59−How to compile this package

60−---------------------------

61−

62−The `cabal2nix.cabal` file for this package is automatically generated by the

63−`generate-cabal-file.hs` program. The easiest way to accomplish that is to run

64−

65− nix-shell release.nix -A cabal2nix.ghc7102.x86_64-linux.env --run "runhaskell generate-cabal-file.hs >cabal2nix.cabal"

66−

67−where `x86_64-linux` should be replaced with whatever system ID is appropriate

68−for your local machine. Basically, `generate-cabal-file.hs` requires the

69−[cartel](http://hackage.haskell.org/package/cartel) library and `git` to run.

70−

71−With the Cabal file in place, this is a normal Haskell project that can be

72−compiled with `cabal-install`.

73−

74−Users of Nix can build this package by running

75−

76− nix-build release.nix -A cabal2nix.ghc7102.x86_64-linux

77−

78−where, again, `x86_64-linux` should be replaced with the appropriate value.

79−This gives you an executable at `result/bin/cabal2nix`. If you'd like to

80−install the latest release version, then

81−

82− nix-env -f "<nixpkgs>" -iA cabal2nix

83−

84−is the way to go.

1+The Future of Haskell Packaging in Nix

2+======================================

3+

4+Fellow Nixers and Haskellers,

5+

6+the [Haskell NG][1] effort allowed us for the first time to distribute the

7+latest version of every package known to Hackage --- well over 8,000 builds in

8+total ---, and this seemed like a crazy leap forward at the time. These days, we

9+distribute [60+ Haskell package sets][2] that represent different views into

10+Hackage built with 8+ different compilers, and there's probably a lot more

11+variety out there, living in our user's `config.nix` files, that we don't even

12+know about. The requirements on our Haskell infrastructure become ever more

13+complex. New questions pop up due to the growing popularity of Stack; our

14+support for old compiler versions is somewhat lacking; and we still don't have

15+convincing answers to questions like: how do I compile my package with

16+profiling support?

17+

18+The issues we have to address are mostly known and understood. What we lack are

19+brilliant ideas how to solve them.

20+

21+This thread is an attempt to make some headway towards that end through open

22+discussion and collaboration. Instead of everyone having to browse a couple of

23+thousand Github tickets to find out what's going on, I'll regularly pick one

24+particular aspect that needs improvement and post a short article outlining the

25+issues we have and potential solutions that we know of so that constructive

26+dialogue can ensue.

27+

28+Everyone is invited to participate in the conversation with ideas, questions,

29+suggestions, or references to Github Pull Requests that implement a perfect,

30+production-ready solution waiting to be merged.

1+Use Function Application To Escape Override Hell

2+================================================

3+

4+The Problem

5+-----------

6+

7+The architecture of the `haskell.packages.*` hierarchy worked fine when Nixpkgs

8+shipped a handful of manually maintained package sets. The addition of LTS

9+Haskell, however, increased the number of active package sets by a factor of

10+10, and that number will grow further since there is a new LTS release coming

11+out every week. Our preferred mechanism to cope with that diversity is the

12+override: `haskellPackages` provides the foundation that other package sets

13+override according to their needs. As of today, this approach requires

14+approximately 25,000 overrides. Furthermore, we use 3 different types of

15+overrides (`override`, `overrideCabal`, and `overrideScope`) that have subtly

16+different purposes and capabilities. The complexity of this technique caused

17+non-trivial issues in the past that manifested in [severe memory leaks][5],

18+[insufficient flexibility][6], and [counter-intuitive behavior][7]. The current

19+approach is not going to scale forever --- particularly in terms of

20+maintainability. We need a better architecture to define Haskell package sets

21+that supports variant builds in a fashion that's simpler and thus easier to

22+understand and maintain.

23+

24+The Situation Today

25+-------------------

26+

27+Nixpkgs distributes over 50 Haskell package sets that differ in which packages

28+they contain, which versions of those packages they contain, and how those

29+builds are configured. For example, package sets intended for use with GHC

30+versions prior to 7.4.x neither build nor run regression test suites, because

31+Cabal introduced that feature only in later versions of the compiler. Package

32+sets compiling with GHC versions prior to 7.8.x don't support shared library

33+builds, because that feature never worked reliably until more recent versions

34+of the compiler. And builds running on Darwin don't generate the Haddock

35+documentation when compiling with GHC versions 7.6.x or earlier, because the

36+Haddock binary on that platform used to interact poorly with Darwin's `cpp` and

37+thus failed until that bug was eventually fixed in GHC 7.8.1.

38+

39+This means that seemingly similar builds like `haskell.packages.ghc763.foo` and

40+`haskell.packages.ghc784.foo` actually differ in multiple dimensions: those two

41+`foo`s may be different versions of the same package; they are almost certainly

42+compiled with different versions of their respective dependencies; and their

43+configurations potentially differ, i.e both builds use different Cabal flags

44+and have different features enabled. In fact, a build of `haskellPackages.foo`

45+that's run on Linux/x86_64 most likely differs non-trivially from the exact

46+same build run on Darwin/x86_64.

47+

48+Nix can handle this diversity, because it describes builds in a Turing-complete

49+functional language. Builds that exist in multiple variants are functions that

50+take the necessary dependencies plus a set of flags to enable/disable the

51+features we intend to support, and then map that information to appropriate

52+build instructions. Those functions live in one central place,

53+[`hackage-packages.nix`][1], and all our crazy package sets simply call those

54+functions with appropriate arguments to define exactly those build variants

55+that they need.

56+

57+What sounds simple and obvious in theory, however, is a bit of a mess in

58+practice. Consider the package `hslua` as an example. `hackage-packages.nix`

59+defines builds for versions 0.3.13, 0.4.0, and 0.4.1. Those definitions look

60+all quite similar, so we'll omit the third definition for brevity:

61+

62+ "hslua_0_3_13" = callPackage

63+ ({ mkDerivation, base, lua5_1, mtl }:

64+ mkDerivation {

65+ pname = "hslua";

66+ version = "0.3.13";

67+ sha256 = "e95774d21ac4378e799af4b8dce9068bfedd3109bf13b717d9ecb5817f86430a";

68+ configureFlags = [ "-fsystem-lua" ];

69+ libraryHaskellDepends = [ base mtl ];

70+ libraryPkgconfigDepends = [ lua5_1 ];

71+ testHaskellDepends = [ base ];

72+ description = "A Lua language interpreter embedding in Haskell";

73+ license = stdenv.lib.licenses.mit;

74+ hydraPlatforms = stdenv.lib.platforms.none;

75+ }) { inherit (pkgs) lua5_1; };

76+

77+ "hslua" = callPackage

78+ ({ mkDerivation, base, bytestring, hspec, hspec-contrib, HUnit

79+ , lua5_1, QuickCheck, quickcheck-instances, text

80+ }:

81+ mkDerivation {

82+ pname = "hslua";

83+ version = "0.4.1";

84+ sha256 = "2df2b4f0566ef2244506f9830e0207fce3bece7c331129f69f446c722136173f";

85+ configureFlags = [ "-fsystem-lua" ];

86+ libraryHaskellDepends = [ base bytestring ];

87+ librarySystemDepends = [ lua5_1 ];

88+ testHaskellDepends = [

89+ base bytestring hspec hspec-contrib HUnit QuickCheck

90+ quickcheck-instances text

91+ ];

92+ description = "A Lua language interpreter embedding in Haskell";

93+ license = stdenv.lib.licenses.mit;

94+ }) { inherit (pkgs) lua5_1; };

95+

96+Let's go through that code step by step. The basic structure of those

97+definitions is

98+

99+ name_version = callPackage f { ... system dependencies ... };

100+

101+where `f` is a function that given a set of build inputs produces a build. The

102+code invokes that function right away, so apparently `name_version` defines a

103+*build*, not a function that generates a build. The arguments passed to `f`

104+contain only system-level dependencies like `lua5_1`. Haskell dependencies like

105+`mtl` are not passed explicitly since the magic `callPackage` function can find

106+them automatically. Haskell attributes have a `_version` suffix only if the

107+attribute refers to an old version, like `hslua_0_3_13`. The latest version,

108+0.4.1, is simply called `hslua`. Last but not least, every Haskell build

109+expects a parameter `mkDerivation` --- our generic Haskell builder, which turns

110+those attribute sets into build instructions that Nix can execute. This

111+argument is also not passed explicitly but found by `callPackage`.

112+

113+The `callPackage` magic relies on two advanced techniques: fixed points and

114+reflection. Nixpkgs defines the Haskell package set recursively as a function

115+`self: { ... }` that takes as an argument the attribute set it's going to

116+produce and then uses that information to the produce the attribute set it's

117+already received as an argument. It's a mind-boggling way to define a recursive

118+attribute set `rec { ... }` without actually using the `rec` keyword. Every

119+computable function of this kind has a fixed point: a value `x` that satisfies

120+`f x = x`. That `x` is the result we actually want --- it's an ordinary

121+attribute set with all the `self`-references resolved and replaced by actual

122+values. The details of fixed points aren't important, though. What's important

123+is that our package set knows its final value already while we're still

124+defining it! This allows for the existence of the `callPackage` function:

125+

126+ self: let

127+ callPackage = stdenv.lib.callPackageWith self;

128+ in

129+ self // { ... Haskell package definitions here ... }

130+

131+The expression `callPackage f args` translates to `stdenv.lib.callPackageWith

132+self f args`. [`callPackageWith`][2] then uses reflection to determine the

133+names of all arguments expected by `f`. It finds those names that don't exist

134+in `args` in `self` and adds them to `args` to complete the function call. In

135+other words, parameters of `f` that are not specified in `args` are

136+automatically filled in from `self` --- the Haskell package set. This is why

137+system packages are passed explicitly (`self` doesn't contain them), but

138+Haskell dependencies are not (`self` does contain them).

139+

140+This feature is nice in package sets human beings write manually, because it

141+allows us to keep function calls short and concise. A computer program

142+generates the file `hackage-packages.nix`, though, so arguably we could have it

143+bind all Haskell names explicitly with `inherit (self) base mtl` just as well.

144+But `callPackage` has another feature that's more important than implicit name

145+resolution: it adds the method `override` to the generated derivation, which

146+can "undo" the function application to change the value of arguments that were

147+used originally. We can say

148+

149+ hslua.override { mtl = self.mtl_2_1_3_1; }

150+

151+to instantiate a variant of `hslua` that compiles with that particular version

152+of `mtl` rather than the default one. The same way, we can change the behavior

153+of `mkDerivation`! For example, the expression

154+

155+ hsload.override {

156+ mkDerivation = args: self.mkDerivation (args // { doCheck=false; });

157+ }

158+

159+gives us a variant of `hslua` that has the test suite disabled. These kind of

160+overrides are so useful that we've defined a whole [set of helper functions][3]

161+that use this technique to customize the default definitions from

162+`hackage-packages.nix` in any way we need.

163+to define

164+Now, Haskell packages sets are just collections of overrides that change the

165+default choices made in `hackage-packages.nix` as required. For example, the

166+package set for [LTS Haskell version 2.8][4] specifies:

167+

168+ "hslua" = doDistribute super."hslua_0_3_13";

169+

170+It renames `hslua_0_3_13` to `hslua` to ensure that all Haskell builds in that

171+package set use the older version instead of the latest one. Furthermore, we

172+would like Hydra builds of `haskell.packages.lts-2_8.hslua` enabled. The

173+original definition from `hackage-packages.nix` disabled those builds via

174+

175+ hydraPlatforms = stdenv.lib.platforms.none

176+

177+which makes sense in `haskellPackages`, because it prefers the latest version

178+of the package, but the older LTS set isn't happy with that choice, so it uses

179+a `doDistribute` override to replace the original empty set of `hydraPlatforms`

180+with something more appropriate.

181+

182+Generally speaking, all of our 50+ Haskell package sets are essentially just

183+variants of `hackage-packages.nix` with certain choices overridden if

184+necessary.

185+

186+Possible Improvements

187+---------------------

188+

189+It's unclear how to improve upon the current architecture.

190+

191+The override approach produces a weird structure: first, we define a build

192+function for every Haskell package --- like one would expect in a purely

193+functional language ---, but then that function isn't exposed. Instead, we call

194+the function right away to create a derivation. However, we can't use an honest

195+function call, because we really need a *function* later, so we're forced to

196+use freaky lazy-evaluation features that allow us to undo the function call

197+with `override` later to make the derivation look like the function again that

198+it probably should have been in the first place.

199+

200+One possible approach is to take `callPackage` out of `hackage-packages.nix`.

201+Instead of derivations, `hackage-packages.nix` could provide functions that

202+package sets then call with appropriate parameters to define the actual build.

203+This would require some 10,000 functions plus another ~7,000 function

204+applications per package set. In the current architecture, some attributes from

205+`hackage-packages.nix` are passed through unmodified, whereas the new approach

206+requires each package set to define every build explicitly. It's unclear how

207+that would affect the Nix interpreter in terms of memory requirements and

208+performance.

209+

210+Furthermore, just taking `callPackage` out of `hackage-packages.nix` won't

211+remedy the need for overriding, because our definitions don't mention any of

212+the build configuration flags, like `doCheck`. It's not possible to call the

213+function

214+

215+ "hslua" =

216+ { mkDerivation, base, bytestring, [... more inputs omitted ...] }:

217+

218+ mkDerivation {

219+ pname = "hslua";

220+ version = "0.4.1";

221+ [... more attributes omitted ...]

222+ };

223+

224+with `hslua { doCheck = false; ... }` because `doCheck` is an argument of

225+`mkDerivation`, which is hidden inside of that function. The established

226+approach to solve that problem is to wrap `mkDerivation`, i.e.

227+

228+ hslua {

229+ mkDerivation = args: self.mkDerivation (args // { doCheck=false; });

230+ }

231+

232+but this feels cumbersome compared to straight function application. We can

233+lift all those `mkDerivation` arguments into the outer function:

234+

235+ "hslua" =

236+ { mkDerivation, base, bytestring, [... more inputs omitted ...]

237+ , doCheck ? true, doHaddock ? true, enableSharedLibraries ? true

238+ }:

239+ mkDerivation {

240+ pname = "hslua";

241+ version = "0.4.1";

242+ inherit doCheck doHaddock;

243+ [... more attributes omitted ...]

244+ };

245+

246+but this adds a dozen highly redundant arguments to every single definition!

247+There might be clever ways around mentioning each of them explicitly, like:

248+

249+ "hslua" =

250+ { mkDerivation, base, bytestring, [... more inputs omitted ...]

251+ , ...

252+ } @ args:

253+ stdenv.lib.callPackageWith args mkDerivation {

254+ pname = "hslua";

255+ version = "0.4.1";

256+ [... more attributes omitted ...]

257+ };

258+

259+Yet that is exactly the kind of stuff we wanted to avoid in the first place. So

260+maybe it would be best to batch all those variant options in an attribute set

261+of their own?

262+

263+ "hslua" =

264+ { mkDerivation, base, bytestring, [... more inputs omitted ...]

265+ , config ? {}

266+ }:

267+ mkDerivation ({

268+ pname = "hslua";

269+ version = "0.4.1";

270+ [... more attributes omitted ...]

271+ } // config);

272+

273+This approach allows us to call `hslua { config.doCheck = false; }`, which

274+seems nice enough. At the same time, it allows us to call

275+

276+ hslua { config.pname = "this-is-not-hslua"; }

277+

278+as well, which feels like a bug.

279+

280+An entirely different approach is to take advantage of lazy evaluation to

281+define all possible build variants at once:

282+

283+ let

284+ showFlag = str: b: (if b then "with" else "without") + "-" + str;

285+

286+ mkDerivation = { pname, version, buildDepends ? []

287+ , doCheck ? true

288+ } @ args:

289+ {

290+ name = pname + "-" + version + "-" + showFlag "check" doCheck;

291+

292+ enableChecking = mkDerivation (args // { doCheck = true; });

293+ disableChecking = mkDerivation (args // { doCheck = false; });

294+ };

295+

296+ "hslua" = { base ? null }:

297+ mkDerivation {

298+ pname = "hslua";

299+ version = "0.4.1";

300+ buildDepends = [ base ];

301+ };

302+ in

303+ [ ((hslua { base = "base"; }).name)

304+ ((hslua { base = "base"; }).disableChecking.name)

305+ ((hslua { base = "base"; }).disableChecking.disableChecking.enableChecking.name)

306+ ]

307+

308+Each of those styles has its own advantages and disadvantages which aren't

309+fully understood yet. Hopefully, this summary provides some food for thought

310+and helps kick off a fruitful discussion.

1+Guarantee Consistent Builds and Obsolete `overrideScope`

2+========================================================

3+

4+The Problem

5+-----------

6+

7+A lot of effort goes into curated package sets like Stackage, but even so we

8+can compile only ~50% of the packages available from Hackage. It appears to be

9+the nature of the game: when `lens` 2.x comes out with a fundamentally new API,

10+then some packages will adopt the new version and others won't. A consistent

11+package set must chose on which side of the fence it wants to live. Either

12+those packages that depend on `lens` 1.x compile or those that depend on 2.x

13+compile --- but not both.

14+

15+Now, Nix is not limited to one particular version of `lens` --- we can have

16+both versions available at the same time. But it's difficult to take advantage

17+of that feature, because once you start mixing `lens` 1.x and 2.x in the same

18+package set, you risk inconsistent builds, i.e. builds where some part of the

19+dependency tree refers to `lens` 1.x and another part refers to `lens` 2.x.

20+It's a bad idea to try and link those two trees together into one executable;

21+we are fortunate that `Cabal` detects this error during the configure phase and

22+aborts the build!

23+

24+We need a mechanism that can mix multiple package versions within a package

25+set, but that also guarantees consistency for every single build. We hoped

26+`overrideScope` would be that mechanism, but somehow it hasn't quite lived up

27+to the promise, mostly because it is hard to understand.

28+

29+The Situation Today

30+-------------------

31+

32+Consider an executable package `foobar` that depends on the libraries `foo` and

33+`bar`, each of which depends on `lens`. The corresponding definitions in

34+`hackage-packages.nix` --- stripped down to the relevant bits --- look as

35+follows:

36+

37+ "lens" = ... lens version 1.x ...;

38+ "lens_2_0" = ... lens version 2.x ...;

39+

40+ "foo" = callPackage

41+ ({ mkDerivation, lens }:

42+ mkDerivation {

43+ pname = "foo";

44+ libraryHaskellDepends = [lens];

45+ }) {};

46+

47+ "bar" = callPackage

48+ ({ mkDerivation, lens }:

49+ mkDerivation {

50+ pname = "bar";

51+ libraryHaskellDepends = [lens];

52+ }) {};

53+

54+ "foobar" = callPackage

55+ ({ mkDerivation, lens }:

56+ mkDerivation {

57+ pname = "foobar"; [...]

58+ libraryHaskellDepends = [foo bar];

59+ }) {};

60+

61+Let's assume that `foo` won't compile in that setup because it requires `lens`

62+version 2.x. We can remedy that by adding an override to

63+`configuration-common.nix` that says:

64+

65+ foo = super.foo.override { lens = self.lens_2_0; };

66+

67+That change fixes the build of `foo`, but `foobar` remains broken, because now

68+it pulls in both `lens` 1.x and 2.x simultaneously through its dependencies. If

69+`bar` works only with `lens` 1.x, then there is nothing we can do: the version

70+constraints conflict and we cannot compile `foobar`. If `bar` *does* support

71+`lens` 2.x, however, then we can just switch it to the newer version with:

72+

73+ bar = super.bar.override { lens = self.lens_2_0; };

74+

75+Now we can compile `foobar`! Unfortunately, that change may break other builds.

76+There is a reason why `lens` 1.x is our default choice. If any other package

77+depends on `bar` as well as `lens` 1.x (directly or indirectly), then it will

78+no longer compile after that change.

79+

80+We can avoid that side-effect by localizing the override to `foobar`:

81+

82+ foobar = super.foobar.override {

83+ bar = self.bar.override { lens = self.lens_2_0; };

84+ };

85+

86+That approach allows us to compile `foobar`, while still leaving the default

87+version of `bar` at `lens` 1.x, like most of our packages require. Overriding

88+build inputs this way works fine, and we have used this technique for many

89+years to fix builds that require non-default versions to compile. The downside

90+of these nested overrides is that the tend to become freaky complicated if a

91+package needs overriding that is sufficiently deep in the dependency tree. The

92+GHC 7.8.4 package set, for example, needed many such overrides because its

93+default version of `mtl` was stuck at version 2.1.x all the while large parts

94+of Hackage had moved on to `mtl` 2.2.x. Since `mtl` is a rather fundamental

95+package, we had nested overrides 3-4 levels deep that were highly repetitious,

96+too. It was a mess.

97+

98+Haskell NG improved on that situation by adding `overrideScope`. That function

99+changes the package set ("scope") in which Nix evaluates a build expression.

100+The override

101+

102+ foobar = super.foobar.overrideScope (self: super: { lens = self.lens_2_0; });

103+

104+creates a new temporary package set, replaces `lens` with `lens_2_0` in it, and

105+then evaluates `foobar`. The `callPackage` function picks up the re-written

106+`lens` attribute, which means that there's no need to override that choice

107+explicitly in all dependencies of `foobar`. One could say that `overrideScope`

108+implements "deep overriding", i.e. it applies an override to the given

109+derivation as well as all sub-derivations that it refers to.

110+

111+Unfortunately, we lack a proper understanding of how expensive that technique

112+is memory and performance-wise. In the past, we've occasionally crashed Nix

113+with this kind of stuff --- keep in mind that the interpreter creates a whole

114+new package set for every build that uses this mechanism ---, but when used

115+sparingly, `overrideScope` seems to work okay.

116+

117+In some cases, `overrideScope` won't work at all, i.e. when confronted with

118+builds that have explicitly passed arguments. For example, let's say that

119+`lens` 3.x comes. So we try to compile `foobar` like this:

120+

121+ foobar = super.foobar.overrideScope (self: super: { lens = self.lens_3_0; });

122+

123+That build will fail, because we added an explicit override for `foo` earlier

124+that committed the build to `lens_2_0`, and `overrideScope` will not affect

125+that choice since that build input is not picked up with `callPackage`. So

126+`foobar` will pull in both `lens` 2.x and 3.x despite the use of

127+`overrideScope`.

128+

129+

130+Possible Improvements

131+---------------------

132+

133+We generate Haskell build expressions automatically with `cabal2nix`, and that

134+tool knows the complete dependency tree for every package. So it would be

135+possible to generate builds that expect as function arguments not just their

136+immediate dependencies but the transitive closure of all dependencies. Build

137+expressions would then call their direct dependencies, passing in appropriate

138+versions of their respective dependencies, etc. For example:

139+

140+ "foobar" = callPackage

141+ ({ mkDerivation, foo, bar, many, other, inputs, of, lens }:

142+ let lens' = lens.override { inherit many other inputs of lens; };

143+ foo' = foo.override { lens = lens'; };

144+ bar' = bar.override { lens = lens'; };

145+ in

146+ mkDerivation {

147+ pname = "foobar"; [...]

148+ libraryHaskellDepends = [foo' bar'];

149+ }) {};

150+

151+Now, `foobar` expects every single package that occurs anywhere inside of its

152+dependency tree as an argument, and it constructs the dependency tree using

153+those arguments. So the build must be consistent. It's impossible for `foobar`

154+to refer to two incompatible versions of `lens`, because its inputs always use

155+the same version.

156+

157+Consequently,

158+

159+ foobar.override { mtl = self.mtl_2.4.0; }

160+

161+gives us is a version of `foobar` that has its entire dependency tree built

162+with `mtl` 2.4.x. We could even get rid of the override altogether if we adopt

163+the suggestions from "Use Function Application To Escape Override Hell" and

164+remove `callPackage` from `hackage-packages.nix`. We'd define all builds as

165+straight functions

166+

167+ "foobar" =

168+ { mkDerivation, foo, bar, many, other, inputs, of, lens }:

169+ let lens' = lens { inherit many other inputs of lens; };

170+ foo' = foo { lens = lens'; };

171+ bar' = bar { lens = lens'; };

172+ in

173+ mkDerivation {

174+ pname = "foobar"; [...]

175+ libraryHaskellDepends = [foo' bar'];

176+ };

177+

178+and invoke them from inside of a package set with:

179+

180+ callPackage foobar { mtl = self.mtl_2.4.0; }

181+

182+This would give us a guarantee for consistent builds without any overrides.

1+Map Cabal Files To Nix Without Information Loss

2+===============================================

3+

4+The Problem

5+-----------

6+

7+Our implementation of `cabal2nix` loses important information, because its

8+mapping from Cabal to Nix is too simplistic. Cabal supports conditional values

9+that depend on

10+

11+- the OS and architecture on which the build takes place,

12+- the compiler version,

13+- the respective versions of the build dependencies, and

14+- Cabal flags.

15+

16+But we don't capture those conditional settings in the generate Nix file.

17+Instead, we resolve those conditions with a set of hard-coded assumptions that

18+work well for Linux/x86_64 using GHC 7.10.2, but other build environments often

19+fail to compile the expression because some essential information is missing.

20+

21+

22+The Situation Today

23+-------------------

24+

25+Consider the Cabal file for [`conduit-1.2.5`][2]. Among other things, it says:

26+

27+ Library

28+ Build-depends: base >= 4.3 && < 5

29+ , resourcet >= 1.1 && < 1.2

30+ , exceptions >= 0.6

31+ , lifted-base >= 0.1

32+ , transformers-base >= 0.4.1 && < 0.5

33+ , transformers >= 0.2.2 && < 0.5

34+ , mtl

35+ , mmorph

36+ if !impl(ghc>=7.9)

37+ build-depends: void >= 0.5.5

38+

39+The library depends on the module `Data.Void`, which GHC's `base` library

40+contains starting with version 7.9.x, but older versions of GHC don't have that

41+module, so the build needs an additional 3rd-party library, `void`, to provide

42+that code. The Nix build expression for `conduit`, however, does not capture

43+that information. `cabal2nix` omits `void` from the list of dependencies

44+entirely:

45+

46+ libraryHaskellDepends = [

47+ base exceptions lifted-base mmorph mtl resourcet transformers

48+ transformers-base

49+ ];

50+

51+The [conversion function][1] used by `cabal2nix` doesn't translate the

52+conditional from Cabal into Nix. Instead, the function

53+[resolves all conditionals][3], assuming that

54+

55+- the build will take place with the same architecture, OS, and compiler

56+version as were used to compile `cabal2nix`,

57+

58+- all Haskell dependencies are available in all versions, and

59+

60+- all Cabal flags have their default value unless specified otherwise in a

61+[hard-coded list][4].

62+

63+For the majority of packages, that heuristic produces build expressions that

64+work fine, but In case of `conduit` the result won't compile with compilers

65+prior to GHC 7.10.x, and thus a

66+[manually configured override is necessary to fix the build][5].

67+

68+The lack of support for conditionals is particularly annoying when it comes to

69+packages that make extensive use of Cabal flags, like `git-annex`. There are

70+numerous flags that determine the feature set supported by the build, i.e.

71+whether to include the "assistant" or not. Now, Stackage package sets like LTS

72+Haskell do contain `git-annex`, but they don't contain all the dependencies

73+that are necessary to build the assistant. Consequently, `git-annex` ought to

74+compile with `-f-assistant` within a context of Stackage. At the same time, we

75+want to provide the assistant feature to Nixpkgs users --- and we can, because

76+we have all of Hackage, not just Stackage!

77+

78+So what we do is this: our generated build expression for `git-annex` by

79+default includes the assistant, and that is the build `gitAndTools.git-annex`

80+refers to. Then we define [variants of that build without the assistant][5],

81+and these are the ones `haskell.packages.lts-x_y.git-annex` refers to. Now, we

82+define that variant by setting the Cabal flag `-f-assistant`, but that override

83+does not change the fact that all those dependencies needed only to build the

84+assistant are still listed as build inputs in the Nix expression for

85+`git-annex`! Cabal won't use these dependencies during the build, but Nix will

86+create them and include them into the build environment nonetheless, which

87+defeats the purpose of having that flag in the first place.

88+

89+Possible Improvements

90+---------------------

91+

92+Nix expressions must capture the complete logic that the underlying Cabal file

93+specifies. In case of the `conduit` example, the generated code should say:

94+

95+ libraryHaskellDepends = [

96+ base exceptions lifted-base mmorph mtl resourcet transformers

97+ transformers-base

98+ ] ++ stdenv.lib.optional (stdenv.lib.versionOlder ghc.version "7.9") void;

99+

100+Furthermore, Cabal flags should be mapped to boolean function arguments that

101+enable/disable the underlying feature and thereby modify how the Nix expression

102+evaluates, so that no extraneous build inputs occur.

1+Set up a Sufficiently Powerful Build Farm

2+=========================================

3+

4+The Problem

5+-----------

6+

7+`hydra.nixos.org` compiles and provides binaries only for the `haskellPackages`

8+package set. The build farm compiles none of our LTS Haskell package sets,

9+which means that users of `haskell.packages.lts-x_y` cannot get any

10+pre-compiled binaries. It also means that those builds aren't verified, i.e. we

11+won't notice when changes to Nixpkgs break builds in those package sets.

12+

13+Furthermore, we have [no pre-compiled binaries with profiling support][1] for

14+any of our package sets.

89+ pkgset builds

90+

91+That gives a total of 111,647 active builds, many of which are identical. All

92+package sets combined define 77,445 distinct store paths, i.e. some 34,202

93+builds are shared across package sets.

94+

95+Now, `hydra.nixos.org` compiles only `haskellPackages` at the moment. Out of a

96+total of [46,862 builds in trunk][2], 15,446 (33%) come from the Haskell

97+package set. If we'd enable every Haskell package set on Linux/i686,

98+Linux/x86_64, and Darwin/x86_64, then we'd have a total of 263,751 builds ---

99+5.6 times as much as before ---, and 88% of all builds would be related to

100+Haskell.

101+

102+A complete build of the active derivations in `haskellPackages` takes up

103+approx. 27 GByte of disk space per platform. That gives about 80 GByte for all

104+of our 3 active platforms. How would that number develop if we'd enable

105+everything? The store path sizes in MByte are distributed as follows (based on

106+7,620 samples excluding `ghc`):

107+

108+ Minimum 1st Quart. Median Mean 3rd Quart. Maximum

109+ 0.0169 0.3557 0.9497 4.6300 3.0640 678.9000

110+

111+Multiplying the average store path size by the number of distinct store paths

112+tells us that storing *everything* requires approx. 360 GByte per platform.

113+With 3 active platforms, we'd need about 1 TByte of disk space for one complete

114+set of Haskell packages.

115+

116+Now, we might be able to reduce that number by disabling some particularly

117+large builds. The store path size distribution is skewed to the left, i.e.

118+towards smaller builds. Approximately 82% of all store paths are actually

119+smaller than the numerical average. Our top-20 biggest Haskell builds are:

120+

121+ pkg size

122+ 1: ghc 895.5

123+ 2: metadata 678.9

124+ 3: uhc-light 253.5

125+ 4: OpenGLRaw 249.3

126+ 5: FpMLv53 229.5

127+ 6: amazonka-ec2 214.8

128+ 7: Agda 212.6

129+ 8: xhb 189.0

130+ 9: unicode-properties 175.0

131+ 10: scholdoc-texmath 165.0

132+ 11: idris 137.7

133+ 12: gf 126.4

134+ 13: pandoc 124.8

135+ 14: unicode-names 118.4

136+ 15: wxcore 113.8

137+ 16: java-character 112.1

138+ 17: hat 111.1

139+ 18: texmath 109.6

140+ 19: open-symbology 107.6

141+ 20: turkish-deasciifier 104.0

142+

143+If we'd make an effort to disable some of those expensive builds --- or maybe

144+reduce their output size ---, then we'd make a noticeable dent into the space

145+requirements. Even so, it's clear that `hydra.nixos.org` cannot provide that

146+much disk space today.

147+

148+Curiously enough, the CPU power necessary to compile all those packages is the

149+least of our problems. Our build farm can easily re-compile everything from

150+scratch within 2-3 days, which is "good enough" for all practical purposes.

151+Also, changes to `stdenv` occur rarely (and we typically know about them in

152+advance). The normal update cycle triggers only a handful of builds -- maybe

153+20-300 per day --, because the versions fundamental Haskell packages are fixed

154+in the LTS package sets.

155+

156+It's unclear whether the Hydra software would cope with 66 package sets with

157+some 111,000 derivations in them that need to be evaluated, say, once an hour.

158+Hydra has undergone some architectural changes recently that might make such a

159+load possible --- i.e. `hydra-evaluator` is more efficient than it used to be

160+---, but I don't have any reliable data concerning the performance of the

161+process, so I cannot say what is possible and what is not.

162+

163+We know for sure that the currently available disk space doesn't suffice. Disk

164+space is notoriously low on `hydra.nixos.org`, and storing another terabyte

165+Haskell data is certainly impossible at the moment.

166+

167+Possible Improvements

168+---------------------

169+

170+We have basically two alternatives:

171+

172+1. Throw hardware (money) at `hydra.nixos.org`.

173+2. Establish a separate build farm for Haskell packages.

174+

175+Either solution requires money, which we could probably raise through crowd

176+funding. At the moment, the NixOS Foundation collects donations for purposes of

177+NixOS in general, but it should be possible to start a funding campaign that

178+collects donations specifically for the purposes of establishing a Haskell

179+build farm so that people who care about that particular topic have an

180+incentive to participate.

181+

182+Now, if we'd go for approach (1), then we could use those funds to buy bigger

183+disks and more RAM for `hydra.nixos.org`, which would be beneficial for

184+everyone -- not just Haskell users. The downside is that `hydra.nixos.org` is a

185+bit of a black box. Only very few people have access to those machines, and

186+that situation is not going to change any time soon. Personally, I have no idea

187+whether adding RAM or disks to the cluster is feasible at all, and whether

188+those upgrades would enable the build farm to cope with the number of builds

189+that we're considering here.

190+

191+Solution (2) seems more manageable, because we could set up an environment from

192+scratch as we see fit. Experience from managing `hydra.cryp.to` suggests that

193+one powerful KVM-based virtual server can serve as the Hydra master. In

194+addition, we'd need 2-3 additional build slaves to compile packages. For

195+massive re-builds, we could spawn another 10-15 builds slaves in EC2 to reduce

196+the time it takes to re-build everything from scratch. Such a setup would

197+probably work well in practice, and it should be available at a yearly cost of

198+1,000 dollars or less.

199+

200+Anyhow, that's just a rough estimate. I don't know, really, what an ideal

201+hardware / service platform for running such a virtual service would be. It

202+would be great if a resident virtual server / NAS / system management guru

203+could chime in with suggestions; I'm sure the NixOS crowd has people who know

204+that kind of stuff and who can design the infrastructure for such a build farm.

1+Publish All of Hackage

2+======================

3+

4+The Problem

5+-----------

6+

7+Users of Nixpkgs want to build Haskell packages that have no recent release,

8+i.e. the software's authors have not updated their code to deal with modern

9+versions of the respective build dependencies. The required old versions,

10+however, may not be available in Nixpkgs, and then the build cannot succeed. At

11+that point, we recommend our users to

12+[add the missing package versions themselves][1] through the override mechanism

13+in `~/.nixpkgs/config.nix`. That approach works fine, but it's challenging for

14+new users and it's certainly inconvenient.

15+

16+The Situation Today

17+-------------------

18+

19+We publish 11,216 package versions out of 62,354 available ones, i.e. 18% of

20+Hackage. We select packages for distribution using the following criteria:

21+

22+1. the latest version of every package (9,058 builds),

23+

24+2. old versions required by LTS Haskell (2,137 builds), and

25+

26+3. old versions manually configured in the `extra-packages` field of

27+ [`configuration-hackage2nix.yaml`][2] (21 builds).

28+

29+The resulting [`hackage-packages.nix`][3] file is ~8.3 MByte large.

30+

31+Now, we could simply publish all of Hackage, i.e. all 62,354 available builds.

32+That would certainly make the lives of many Haskell hackers easier, but

33+unfortunately the resulting `hackage-packages.nix` file would require 52 MByte

34+of space. Furthermore, simple benchmarks suggest that `nix-instantiate` needs a

35+whopping 4 seconds to instantiate a `ghcWithPackages` environment from the new

36+database where instantiating the same environment used to take 0.45 seconds

37+before --- a performance drop by a factor of 8.

38+

39+Possible Improvements

40+---------------------

41+

42+We could continue to publish the "small" `hackage-packages.nix` database by

43+default, but generate an additional large database that we'd store in a

44+separate location. We would then add support for an option to

45+`~/.nixpkgs/config.nix` users could set to opt in to using the large database

46+if they want to. That way, Haskell users would have an option to get all of

47+Hackage without causing a performance drop for everyone else.

48+

49+One issue is that checking that ~50MB file into Nixpkgs might be a bad idea,

50+because it sets a dangerous precedent. Arguably, if we check all of Hackage

51+into Nixpkgs, then we cannot reasonably say *no* to someone who wants to check

52+all of CPAN into Nixpkgs too, and before we know it our Git repository triples

53+in size. So it might be wise to put the full Hackage variant of

54+`hackage-packages.nix` into a separate repository that we fetch via

55+`builtins.fetchurl` if the corresponding option is enabled.

56+

57+An altogether different approach is to improve our tools like `cabal2nix` to

58+make it convenient to add old versions from Hackage into a local Nixpkgs

59+instance, i.e. by extending the program to generate builds for all missing

60+versions to complete the transitive closure of the requested build so that

61+users don't have to run it a dozen times because multiple old versions are

62+missing. Conceivably, we could also provide tools that manage

63+`~/.nixpkgs/config.nix`, which might be a good idea independent of these

64+Haskell-specific issues.

29+* TODO Write a =ghcWithPackages= combinator to create conglomerate workspaces

30+

31+ Thomas Strobel <thomas@strobel.eu> suggested this:

32+

33+ I want to hack on a set of libraries, say transformers and mtl, and I'd like

34+ to do that in an environment that contains criterion, QuickCheck, etc. So I

35+ run

36+

37+ stackWithPackages (hp: {

38+ sources = with hp; [transformers mtl];

39+ env = with hp; [criterion QuickCheck];

40+ })

41+

42+ This should create a conglomerate workspace / nix-shell environment that

43+ contains the source code for transformers and lens in subdirectories plus a

44+ stack.yaml file that builds them both:

45+

46+ stack.yaml

47+ mtl / ...

48+ transformers ...

49+

50+ The environment would contain a GHC with criterion and QuickCheck registered

51+ in appropriate LTS versions so that the stack builds don't compile anything

52+ except the packages I'm hacking on.

53+

54+ The value of env could possibly be auto-determined from the dependencies of

55+ transformers and mtl.

56+* TODO Solve the too-eager evaluation of meta.broken

57+

58+ We'd like to mark builds that are known to fail with `meta.broken = true`,

59+ but this is impractical because users have no way to override that setting if

60+ they discover that the package has been fixed in a new version.

111+

112+# Hackage: Destructive Editing

113+

114+`MonadRandom/0.4/MonadRandom.cabal` contains a line:

115+

116+ x-revision: 2

117+

118+This translates to Nix:

119+

120+ revision = "2";

121+ editedCabalFile = "2e218afd5b29c868...";

122+

123+The build log will say:

124+

125+> Replace Cabal file with edited version from

126+> http://hackage.haskell.org/package/MonadRandom-0.4/revision/2.cabal.

127+

128+-------------------------------------------------------------------------------

129+

130+# Hackage: Conditional Values

131+

132+Values in Cabal files may depend on OS, architecture, compiler, and flags.

133+For example, hint 0.4.2.3 specifies:

134+

135+ Library

136+ if impl(ghc >= 6.8)

137+ build-depends: random, directory

138+ if impl(ghc >= 6.10)

139+ build-depends: base >= 4, base < 5,

140+ ghc-mtl == 1.2.1.*

141+ else

142+ build-depends: base >= 3, base < 4

143+ else

144+ build-depends: utf8-string < 0.3

145+ if !os(windows)

146+ build-depends: unix >= 2.2.0.0

147+

148+-------------------------------------------------------------------------------

149+

150+# Hackage: Cabal Flags

151+

152+Flags can be specified by the user or auto-configured by the build to fit the

153+environment. For example, pandoc 1.15.1.1 defines:

154+

155+ Flag https

156+ Description: Enable support for downloading over https.

157+

158+ Library

159+ Build-Depends: base >= 4.2 && <5,

160+ syb >= 0.1 && < 0.7,

161+ [...]

162+ ghc-prim >= 0.2

163+ if flag(https)

164+ Build-Depends: http-client >= 0.3.2 && < 0.5,

165+ http-client-tls >= 0.2 && < 0.3,

166+ http-types >= 0.8 && < 0.10

167+

168+-------------------------------------------------------------------------------

169+

170+# Stackage: Stable Hackage

171+

172+- 1,605 packages (18% of Hackage)

173+

174+- Build instructions published via Git specify parameters such as "don't run

175+ test suite", "don't run Haddock", etc.

176+

177+- Testing takes place on 64-bit Linux.

178+

179+- Nightly Snapshots contain the latest version of every package such that the

180+ package set is consistent.

181+

182+- LTS minor releases are created weekly and contain only point releases that

183+ don't change the API.

184+

185+- LTS major releases contain API-breaking changes and usually conincide with a

186+ compiler update.

187+

188+-------------------------------------------------------------------------------

189+

190+# cabal2nix & hackage2nix

191+

192+- Code lives at <https://github.com/NixOS/cabal2nix>:

193+ - `distribution-nixpkgs` library

194+ - `cabal2nix` executable

195+ - `hackage2nix` executable

196+

197+- [`update-nixpkgs.sh`](https://github.com/NixOS/cabal2nix/blob/master/hackage2nix/update-nixpkgs.sh)

198+ script runs automatically once per hour.

199+

200+- Changes go to `haskell-updates` branch in [peti's Nixpkgs fork on Github](https://github.com/peti/nixpkgs).

201+

202+- [`hydra.cryp.to`](http://hydra.cryp.to/jobset/nixpkgs/haskell-updates)

203+ continuously builds Stackage Nightly and the latest LTS Haskell package set.

204+

205+- If Hydra builds work sufficiently well, updates are manually merged into

206+ `master` branch of main repository.

207+

208+- [`generate-nixpkgs-haskell-package-list`](https://github.com/peti/package-list)

209+ utility manually publishes new state of Nixpkgs on Hackage.

210+

211+-------------------------------------------------------------------------------

212+

213+# Nixpkgs: `hackage-packages.nix`

214+

215+The package set is represented as a primitive recursive function:

216+

217+ ps = self: {

218+ "3d-graphics-examples" = callPackage ...;

219+ ...

220+ "mtl_2_1_3_1" = callPackage ...;

221+ "mtl" = callPackage ...;

222+ ...

223+ "ztail" = callPackage ...;

224+ };

225+

226+The Nixpkgs attribute set `haskellPackages` refers to the fixpoint of that

227+function which is computed by the expression:

228+

229+ let self = ps self;

230+ in # = ps (ps self) = ps (ps (ps (self))) = ...

231+ self

232+

233+-------------------------------------------------------------------------------

234+

235+# Nixpkgs: hackage-packages.nix

236+

237+We can modify the package set using OO-style inheritance:

238+

239+ fix = f: let self = f self; in self;

240+ extend = rattrs: f: self: let super = rattrs self;

241+ in super // f self super;

242+

243+ ps = self: {

244+ foo = "foo"; bar = "bar";

245+ foobar = self.foo + self.bar;

246+ };

247+

248+ f = self: super: { foo = reverse super.foo; };

249+

250+- `(fix ps).foobar` $\equiv$ `"foobar"`

251+- `(fix (extend ps f)).foobar` $\equiv$ `"oofbar"`

252+- `(fix (extend (extend ps f) f)).foobar` $\equiv$ `"foobar"`

253+

254+-------------------------------------------------------------------------------

255+

256+# Nixpkgs: pkgs/development/haskell-modules/default.nix

257+

258+ { compilerConfig ? (self: super: {})

259+ , packageSetConfig ? (self: super: {})

260+ , overrides ? (self: super: {})

261+ }:

262+

263+ fix

264+ (extend

265+ (extend

266+ (extend

267+ (extend haskellPackages commonConfiguration)

268+ compilerConfig)

269+ packageSetConfig)

270+ overrides)

271+

272+-------------------------------------------------------------------------------

273+

274+# Nixpkgs: Multiple Views Of The Package Set

275+

276+- `hackage-packages.nix` represents "Stackage Nightly".

277+

278+- `configuration-common.nix` "extends" that to work around deficiencies in

279+ `hackage2nix`.

280+

281+- `configuration-ghc-x.y.nix` "extends" that with fixes relevant only for

282+ particular compiler versions: `haskell.packages.ghcXY`.

283+

284+- `configuration-lts-v.w.nix` "extends" those sets to choose default versions

285+ according to "LTS Haskell x.y": `haskell.packages.lts-x_y`.

286+

287+-------------------------------------------------------------------------------

288+

289+# Nixpkgs: `overrideCabal`

290+

291+Haskell derivations take the `mkDerivation` function as an argument:

292+

293+ { mkDerivation, ... }: mkDerivation {

294+ pname = "mtl";

295+ version = "2.2.1";

296+ ...

297+ }

298+

299+The `override` method changes the arguments passed to a derivation --- so we

300+can change the definition of `mkDerivation`:

301+

302+ overrideCabal = drv: f: drv.override (args: args // {

303+ mkDerivation = drv: args.mkDerivation (drv // f drv);

304+ });

305+

306+-------------------------------------------------------------------------------

307+

308+# Nixpkgs: `haskell.lib` Helper Functions

309+

310+ doHaddock = ...;

311+ dontHaddock = drv: overrideCabal drv (drv: {

312+ doHaddock = false;

313+ });

314+

315+ enableLibraryProfiling = ...;

316+ disableLibraryProfiling = drv: overrideCabal drv (drv: {

317+ enableLibraryProfiling = false;

318+ });

319+

320+ addBuildTool = drv: x: addBuildTools drv [x];

321+ addBuildTools = drv: xs: overrideCabal drv (drv: {

322+ buildTools = (drv.buildTools or []) ++ xs;

323+ });

2−title: User's Guide for Haskell in Nixpkgs

3−author: Peter Simons

4−date: 2015-06-01

7−# How to install Haskell packages

8−

9−Nixpkgs distributes build instructions for all Haskell packages registered on

10−[Hackage](http://hackage.haskell.org/), but strangely enough normal Nix package

11−lookups don't seem to discover any of them:

12−

13− $ nix-env -qa cabal-install

14− error: selector ‘cabal-install’ matches no derivations

15−

16− $ nix-env -i ghc

17− error: selector ‘ghc’ matches no derivations

18−

19−The Haskell package set is not registered in the top-level namespace because it

20−is *huge*. If all Haskell packages were visible to these commands, then

21−name-based search/install operations would be much slower than they are now. We

22−avoided that by keeping all Haskell-related packages in a separate attribute

23−set called `haskellPackages`, which the following command will list:

24−

25− $ nix-env -f "<nixpkgs>" -qaP -A haskellPackages

26− haskellPackages.a50 a50-0.5

27− haskellPackages.abacate haskell-abacate-0.0.0.0

28− haskellPackages.abcBridge haskell-abcBridge-0.12

29− haskellPackages.afv afv-0.1.1

30− haskellPackages.alex alex-3.1.4

31− haskellPackages.Allure Allure-0.4.101.1

32− haskellPackages.alms alms-0.6.7

33− [... some 8000 entries omitted ...]

34−

35−To install any of those packages into your profile, refer to them by their

36−attribute path (first column):

37−

38− $ nix-env -f "<nixpkgs>" -iA haskellPackages.Allure ...

39−

40−The attribute path of any Haskell packages corresponds to the name of that

41−particular package on Hackage: the package `cabal-install` has the attribute

42−`haskellPackages.cabal-install`, and so on. (Actually, this convention causes

43−trouble with packages like `3dmodels` and `4Blocks`, because these names are

44−invalid identifiers in the Nix language. The issue of how to deal with these

45−rare corner cases is currently unresolved.)

46−

47−Haskell packages who's Nix name (second column) begins with a `haskell-` prefix

48−are packages that provide a library whereas packages without that prefix

49−provide just executables. Libraries may provide executables too, though: the

50−package `haskell-pandoc`, for example, installs both a library and an

51−application. You can install and use Haskell executables just like any other

52−program in Nixpkgs, but using Haskell libraries for development is a bit

53−trickier and we'll address that subject in great detail in section [How to

54−create a development environment].

55−

56−Attribute paths are deterministic inside of Nixpkgs, but the path necessary to

57−reach Nixpkgs varies from system to system. We dodged that problem by giving

58−`nix-env` an explicit `-f "<nixpkgs>"` parameter, but if you call `nix-env`

59−without that flag, then chances are the invocation fails:

60−

61− $ nix-env -iA haskellPackages.cabal-install

62− error: attribute ‘haskellPackages’ in selection path

63− ‘haskellPackages.cabal-install’ not found

64−

65−On NixOS, for example, Nixpkgs does *not* exist in the top-level namespace by

66−default. To figure out the proper attribute path, it's easiest to query for the

67−path of a well-known Nixpkgs package, i.e.:

68−

69− $ nix-env -qaP coreutils

70− nixos.pkgs.coreutils coreutils-8.23

71−

72−If your system responds like that (most NixOS installatios will), then the

73−attribute path to `haskellPackages` is `nixos.pkgs.haskellPackages`. Thus, if

74−you want to use `nix-env` without giving an explicit `-f` flag, then that's the

75−way to do it:

76−

77− $ nix-env -qaP -A nixos.pkgs.haskellPackages

78− $ nix-env -iA nixos.pkgs.haskellPackages.cabal-install

79−

80−Our current default compiler is GHC 7.10.x and the `haskellPackages` set

81−contains packages built with that particular version. Nixpkgs contains the

82−latest major release of every GHC since 6.10.4, however, and there is a whole

83−family of package sets available that defines Hackage packages built with each

84−of those compilers, too:

85−

86− $ nix-env -f "<nixpkgs>" -qaP -A haskell.packages.ghc6123

87− $ nix-env -f "<nixpkgs>" -qaP -A haskell.packages.ghc763

88−

89−The name `haskellPackages` is really just a synonym for

90−`haskell.packages.ghc7101`, because we prefer that package set internally and

91−recommend it to our users as their default choice, but ultimately you are free

92−to compile your Haskell packages with any GHC version you please. The following

93−command displays the complete list of available compilers:

94−

95− $ nix-env -f "<nixpkgs>" -qaP -A haskell.compiler

96− haskell.compiler.ghc6104 ghc-6.10.4

97− haskell.compiler.ghc6123 ghc-6.12.3

98− haskell.compiler.ghc704 ghc-7.0.4

99− haskell.compiler.ghc722 ghc-7.2.2

116−## How to install a compiler

117−

118−A simple development environment consists of a Haskell compiler and the tool

119−`cabal-install`, and we saw in section [How to install Haskell packages] how

120−you can install those programs into your user profile:

121−

122− $ nix-env -f "<nixpkgs>" -iA haskellPackages.ghc haskellPackages.cabal-install

123−

124−Instead of the default package set `haskellPackages`, you can also use the more

125−precise name `haskell.compiler.ghc7101`, which has the advantage that it refers

126−to the same GHC version regardless of what Nixpkgs considers "default" at any

127−given time.

128−

129−Once you've made those tools available in `$PATH`, it's possible to build

130−Hackage packages the same way people without access to Nix do it all the time:

131−

132− $ cabal get lens-4.11 && cd lens-4.11

133− $ cabal install -j --dependencies-only

134− $ cabal configure

135− $ cabal build

136−

137−If you enjoy working with Cabal sandboxes, then that's entirely possible too:

138−just execute the command

139−

140− $ cabal sandbox init

141−

142−before installing the required dependencies.

143−

144−The `nix-shell` utility makes it easy to switch to a different compiler

145−version; just enter the Nix shell environment with the command

146−

147− $ nix-shell -p haskell.compiler.ghc784

148−

149−to bring GHC 7.8.4 into `$PATH`. Re-running `cabal configure` switches your

150−build to use that compiler instead. If you're working on a project that doesn't

151−depend on any additional system libraries outside of GHC, then it's sufficient

152−even to run the `cabal configure` command inside of the shell:

153−

154− $ nix-shell -p haskell.compiler.ghc784 --command "cabal configure"

155−

156−Afterwards, all other commands like `cabal build` work just fine in any shell

157−environment, because the configure phase recorded the absolute paths to all

158−required tools like GHC in its build configuration inside of the `dist/`

159−directory. Please note, however, that `nix-collect-garbage` can break such an

160−environment because the Nix store paths created by `nix-shell` aren't "alive"

161−anymore once `nix-shell` has terminated. If you find that your Haskell builds

162−no longer work after garbage collection, then you'll have to re-run `cabal

163−configure` inside of a new `nix-shell` environment.

164−

165−## How to install a compiler with libraries

166−

167−GHC expects to find all installed libraries inside of its own `lib` directory.

168−This approach works fine on traditional Unix systems, but it doesn't work for

169−Nix, because GHC's store path is immutable once it's built. We cannot install

170−additional libraries into that location. As a consequence, our copies of GHC

171−don't know any packages except their own core libraries, like `base`,

172−`containers`, `Cabal`, etc.

173−

174−We can register additional libraries to GHC, however, using a special build

175−function called `ghcWithPackages`. That function expects one argument: a

176−function that maps from an attribute set of Haskell packages to a list of

177−packages, which determines the libraries known to that particular version of

178−GHC. For example, the Nix expression `ghcWithPackages (pkgs: [pkgs.mtl])`

179−generates a copy of GHC that has the `mtl` library registered in addition to

180−its normal core packages:

181−

182− $ nix-shell -p "haskellPackages.ghcWithPackages (pkgs: [pkgs.mtl])"

183−

184− [nix-shell:~]$ ghc-pkg list mtl

185− /nix/store/zy79...-ghc-7.10.1/lib/ghc-7.10.1/package.conf.d:

186− mtl-2.2.1

187−

188−This function allows users to define their own development environment by means

189−of an override. After adding the following snippet to `~/.nixpkgs/config.nix`,

190−

191− {

192− packageOverrides = super: let self = super.pkgs; in

193− {

194− myHaskellEnv = self.haskell.packages.ghc7101.ghcWithPackages

195− (haskellPackages: with haskellPackages; [

196− # libraries

197− arrows async cgi criterion

198− # tools

199− cabal-install haskintex

200− ]);

201− };

202− }

203−

204−it's possible to install that compiler with `nix-env -f "<nixpkgs>" -iA

205−myHaskellEnv`. If you'd like to switch that development environment to a

206−different version of GHC, just replace the `ghc7101` bit in the previous

207−definition with the appropriate name. Of course, it's also possible to define

208−any number of these development environments! (You can't install two of them

209−into the same profile at the same time, though, because that would result in

210−file conflicts.)

211−

212−The generated `ghc` program is a wrapper script that re-directs the real

213−GHC executable to use a new `lib` directory --- one that we specifically

214−constructed to contain all those packages the user requested:

215−

216− $ cat $(type -p ghc)

217− #! /nix/store/xlxj...-bash-4.3-p33/bin/bash -e

218− export NIX_GHC=/nix/store/19sm...-ghc-7.10.1/bin/ghc

219− export NIX_GHCPKG=/nix/store/19sm...-ghc-7.10.1/bin/ghc-pkg

220− export NIX_GHC_DOCDIR=/nix/store/19sm...-ghc-7.10.1/share/doc/ghc/html

221− export NIX_GHC_LIBDIR=/nix/store/19sm...-ghc-7.10.1/lib/ghc-7.10.1

222− exec /nix/store/j50p...-ghc-7.10.1/bin/ghc "-B$NIX_GHC_LIBDIR" "$@"

223−

224−The variables `$NIX_GHC`, `$NIX_GHCPKG`, etc. point to the *new* store path

225−`ghcWithPackages` constructed specifically for this environment. The last line

226−of the wrapper script then executes the real `ghc`, but passes the path to the

227−new `lib` directory using GHC's `-B` flag.

228−

229−The purpose of those environment variables is to work around an impurity in the

230−popular [ghc-paths](http://hackage.haskell.org/package/ghc-paths) library. That

231−library promises to give its users access to GHC's installation paths. Only,

232−the library can't possible know that path when it's compiled, because the path

233−GHC considers its own is determined only much later, when the user configures

234−it through `ghcWithPackages`. So we [patched

235−ghc-paths](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/haskell-modules/ghc-paths-nix.patch)

236−to return the paths found in those environment variables at run-time rather

237−than trying to guess them at compile-time.

238−

239−To make sure that mechanism works properly all the time, we recommend that you

240−set those variables to meaningful values in your shell environment, too, i.e.

241−by adding the following code to your `~/.bashrc`:

242−

243− if type >/dev/null 2>&1 -p ghc; then

244− eval "$(egrep ^export "$(type -p ghc)")"

245− fi

246−

247−If you are certain that you'll use only one GHC environment which is located in

248−your user profile, then you can use the following code, too, which has the

249−advantage that it doesn't contain any paths from the Nix store, i.e. those

250−settings always remain valid even if a `nix-env -u` operation updates the GHC

251−environment in your profile:

252−

253− if [ -e ~/.nix-profile/bin/ghc ]; then

254− export NIX_GHC="$HOME/.nix-profile/bin/ghc"

260−## How to create ad hoc environments for `nix-shell`

261−

262−The easiest way to create an ad hoc development environment is to run

263−`nix-shell` with the appropriate GHC environment given on the command-line:

264−

265− nix-shell -p "haskellPackages.ghcWithPackages (pkgs: with pkgs; [mtl pandoc])"

266−

267−For more sophisticated use-cases, however, it's more convenient to save the

268−desired configuration in a file called `shell.nix` that looks like this:

269−

270− { nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7101" }:

271− let

272− inherit (nixpkgs) pkgs;

273− ghc = pkgs.haskell.packages.${compiler}.ghcWithPackages (ps: with ps; [

274− monad-par mtl

275− ]);

276− in

277− pkgs.stdenv.mkDerivation {

278− name = "my-haskell-env-0";

279− buildInputs = [ ghc ];

280− shellHook = "eval $(egrep ^export ${ghc}/bin/ghc)";

281− }

282−

283−Now run `nix-shell` --- or even `nix-shell --pure` --- to enter a shell

284−environment that has the appropriate compiler in `$PATH`. If you use `--pure`,

285−then add all other packages that your development environment needs into the

286−`buildInputs` attribute. If you'd like to switch to a different compiler

287−version, then pass an appropriate `compiler` argument to the expression, i.e.

288−`nix-shell --argstr compiler ghc784`.

289−

290−If you need such an environment because you'd like to compile a Hackage package

291−outside of Nix --- i.e. because you're hacking on the latest version from Git

292−---, then the package set provides suitable nix-shell environments for you

293−already! Every Haskell package has an `env` attribute that provides a shell

294−environment suitable for compiling that particular package. If you'd like to

295−hack the `lens` library, for example, then you just have to check out the

296−source code and enter the appropriate environment:

297−

298− $ cabal get lens-4.11 && cd lens-4.11

299− Downloading lens-4.11...

300− Unpacking to lens-4.11/

301−

302− $ nix-shell "<nixpkgs>" -A haskellPackages.lens.env

303− [nix-shell:/tmp/lens-4.11]$

304−

305−At point, you can run `cabal configure`, `cabal build`, and all the other

306−development commands. Note that you need `cabal-install` installed in your

307−`$PATH` already to use it here --- the `nix-shell` environment does not provide

308−it.

310−# How to create Nix builds for your own private Haskell packages

311−

312−If your own Haskell packages have build instructions for Cabal, then you can

313−convert those automatically into build instructions for Nix using the

314−`cabal2nix` utility, which you can install into your profile by running

315−`nix-env -i cabal2nix`.

316−

317−## How to build a stand-alone project

318−

319−For example, let's assume that you're working on a private project called

320−`foo`. To generate a Nix build expression for it, change into the project's

321−top-level directory and run the command:

322−

323− $ cabal2nix . >foo.nix

324−

325−Then write the following snippet into a file called `default.nix`:

326−

327− { nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7101" }:

328− nixpkgs.pkgs.haskell.packages.${compiler}.callPackage ./foo.nix { }

329−

330−Finally, store the following code in a file called `shell.nix`:

331−

332− { nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7101" }:

333− (import ./default.nix { inherit nixpkgs compiler; }).env

334−

335−At this point, you can run `nix-build` to have Nix compile your project and

336−install it into a Nix store path. The local directory will contain a symlink

337−called `result` after `nix-build` returns that points into that location. Of

338−course, passing the flag `--argstr compiler ghc763` allows switching the build

339−to any version of GHC currently supported.

340−

341−Furthermore, you can call `nix-shell` to enter an interactive development

342−environment in which you can use `cabal configure` and `cabal build` to develop

343−your code. That environment will automatically contain a proper GHC derivation

344−with all the required libraries registered as well as all the system-level

345−libraries your package might need.

346−

347−If your package does not depend on any system-level libraries, then it's

348−sufficient to run

349−

350− $ nix-shell --command "cabal configure"

351−

352−once to set up your build. `cabal-install` determines the absolute paths to all

353−resources required for the build and writes them into a config file in the

354−`dist/` directory. Once that's done, you can run `cabal build` and any other

355−command for that project even outside of the `nix-shell` environment. This

356−feature is particularly nice for those of us who like to edit their code with

357−an IDE, like Emacs' `haskell-mode`, because it's not necessary to start Emacs

358−inside of nix-shell just to make it find out the necessary settings for

359−building the project; `cabal-install` has already done that for us.

360−

361−If you want to do some quick-and-dirty hacking and don't want to bother setting

362−up a `default.nix` and `shell.nix` file manually, then you can use the

363−`--shell` flag offered by `cabal2nix` to have it generate a stand-alone

364−`nix-shell` environment for you. With that feature, running

365−

366− $ cabal2nix --shell . >shell.nix

367− $ nix-shell --command "cabal configure"

368−

369−is usually enough to set up a build environment for any given Haskell package.

370−You can even use that generated file to run `nix-build`, too:

371−

372− $ nix-build shell.nix

373−

374−## How to build projects that depend on each other

375−

376−If you have multiple private Haskell packages that depend on each other, then

377−you'll have to register those packages in the Nixpkgs set to make them visible

378−for the dependency resolution performed by `callPackage`. First of all, change

379−into each of your projects top-level directories and generate a `default.nix`

380−file with `cabal2nix`:

381−

382− $ cd ~/src/foo && cabal2nix . >default.nix

383− $ cd ~/src/bar && cabal2nix . >default.nix

384−

385−Then edit your `~/.nixpkgs/config.nix` file to register those builds in the

386−default Haskell package set:

387−

388− {

389− packageOverrides = super: let self = super.pkgs; in

396− };

397− };

398− }

399−

400−Once that's accomplished, `nix-env -f "<nixpkgs>" -qA haskellPackages` will

402−

403− $ nix-build "<nixpkgs>" -A haskellPackages.foo

415−feature is to replace the default `mkDerivation` function with one that enables

432−## How to override package versions in a compiler-specific package set

433−

434−Nixpkgs provides the latest version of

435−[`ghc-events`](http://hackage.haskell.org/package/ghc-events), which is 0.4.4.0

436−at the time of this writing. This is fine for users of GHC 7.10.x, but GHC

437−7.8.4 cannot compile that binary. Now, one way to solve that problem is to

438−register an older version of `ghc-events` in the 7.8.x-specific package set.

439−The first step is to generate Nix build instructions with `cabal2nix`:

440−

441− $ cabal2nix cabal://ghc-events-0.4.3.0 >~/.nixpkgs/ghc-events-0.4.3.0.nix

442−

443−Then add the override in `~/.nixpkgs/config.nix`:

444−

445− {

446− packageOverrides = super: let self = super.pkgs; in

447− {

448− haskell = super.haskell // {

453− };

454− };

455− };

456− };

457− };

458− }

459−

460−This code is a little crazy, no doubt, but it's necessary because the intuitive

461−version

462−

463− haskell.packages.ghc784 = super.haskell.packages.ghc784.override {

464− overrides = self: super: {

465− ghc-events = self.callPackage ./ghc-events-0.4.3.0.nix {};

466− };

467− };

468−

469−doesn't do what we want it to: that code replaces the `haskell` package set in

470−Nixpkgs with one that contains only one entry,`packages`, which contains only

471−one entry `ghc784`. This override loses the `haskell.compiler` set, and it

472−loses the `haskell.packages.ghcXYZ` sets for all compilers but GHC 7.8.4. To

473−avoid that problem, we have to perform the convoluted little dance from above,

474−iterating over each step in hierarchy.

475−

476−Once it's accomplished, however, we can install a variant of `ghc-events`

477−that's compiled with GHC 7.8.4:

478−

479− nix-env -f "<nixpkgs>" -iA haskell.packages.ghc784.ghc-events

480−

481−Unfortunately, it turns out that this build fails again while executing the

482−test suite! Apparently, the release archive on Hackage is missing some data

483−files that the test suite requires, so we cannot run it. We accomplish that by

484−re-generating the Nix expression with the `--no-check` flag:

485−

486− $ cabal2nix --no-check cabal://ghc-events-0.4.3.0 >~/.nixpkgs/ghc-events-0.4.3.0.nix

487−

488−Now the builds succeeds.

489−

490−Of course, in the concrete example of `ghc-events` this whole exercise is not

491−an ideal solution, because `ghc-events` can analyze the output emitted by any

492−version of GHC later than 6.12 regardless of the compiler version that was used

493−to build the `ghc-events' executable, so strictly speaking there's no reason to

494−prefer one built with GHC 7.8.x in the first place. However, for users who

495−cannot use GHC 7.10.x at all for some reason, the approach of downgrading to an

1+# Hackage2nix

2+

3+This tool is used to update the `hackage-packages.nix` file in the nixpkgs repo.

4+Most of the time we will not need run this manually (since it is run automatically

5+on the upstream nixpkgs). The cases when we would need to run this manually are:

6+

7+* We have changed hackage2nix in some way and we want to check that it

8+behaves correctly.

9+

10+* We have a fork of nixpkgs where we have added or changed

11+the name or location in nixpkgs of a native package used by a hackage package

12+and we want to check that hackage-packages.nix will be updated correctly.

13+

14+**Important:** this must be run on a **case sensitive file system**.

15+On macOS you can use [this](https://gist.github.com/dixson3/8360571) to create one

16+(you can replace 60g with 4g as that should be plenty).

17+

18+There is a [video on YouTube](https://www.youtube.com/watch?v=qX0mgtSm360)

19+that gives a thorough walk-through of these steps.

20+

21+#### Setup

22+Replace `git@github.com:NixOS/nixpkgs.git` with a fork you have access to.

23+```

24+git clone git@github.com:NixOS/cabal2nix.git

25+cd cabal2nix

26+git clone git@github.com:NixOS/nixpkgs.git

27+git clone git@github.com:commercialhaskell/all-cabal-hashes.git --branch hackage hackage

28+cabal install

29+```

30+

31+#### Running Hackage2nix

32+Runs hackage2nix and pushes a commit with the updated `hackage-packages.nix`

8+synopsis: For testing partial and infinite values.

9+description:

10+ Do you ever feel the need to test code involving bottoms (e.g. calls to

11+ the @error@ function), or code involving infinite values? Then this

12+ library could be useful for you.

13+ .

14+ It is usually easy to get a grip on bottoms by showing a value and

15+ waiting to see how much gets printed before the first exception is

16+ encountered. However, that quickly gets tiresome and is hard to automate

17+ using e.g. QuickCheck

18+ (<http://www.cse.chalmers.se/~rjmh/QuickCheck/>). With this library you

19+ can do the tests as simply as the following examples show.

20+ .

21+ Testing explicitly for bottoms:

22+ .

23+ > > isBottom (head [])

24+ > True

25+ .

26+ > > isBottom bottom

27+ > True

28+ .

29+ > > isBottom (\_ -> bottom)

30+ > False

31+ .

32+ > > isBottom (bottom, bottom)

33+ > False

34+ .

35+ Comparing finite, partial values:

36+ .

37+ > > ((bottom, 3) :: (Bool, Int)) ==! (bottom, 2+5-4)

38+ > True

39+ .

40+ > > ((bottom, bottom) :: (Bool, Int)) <! (bottom, 8)

41+ > True

42+ .

43+ Showing partial and infinite values (@\\\/!@ is join and @\/\\!@ is meet):

44+ .

45+ > > approxShow 4 $ (True, bottom) \/! (bottom, 'b')

46+ > "Just (True, 'b')"

47+ .

48+ > > approxShow 4 $ (True, bottom) /\! (bottom, 'b')

49+ > "(_|_, _|_)"

50+ .

51+ > > approxShow 4 $ ([1..] :: [Int])

52+ > "[1, 2, 3, _"

53+ .

54+ > > approxShow 4 $ (cycle [bottom] :: [Bool])

55+ > "[_|_, _|_, _|_, _"

56+ .

57+ Approximately comparing infinite, partial values:

58+ .

59+ > > approx 100 [2,4..] ==! approx 100 (filter even [1..] :: [Int])

60+ > True

61+ .

62+ > > approx 100 [2,4..] /=! approx 100 (filter even [bottom..] :: [Int])

63+ > True

64+ .

65+ The code above relies on the fact that @bottom@, just as @error

66+ \"...\"@, @undefined@ and pattern match failures, yield

67+ exceptions. Sometimes we are dealing with properly non-terminating

68+ computations, such as the following example, and then it can be nice to

69+ be able to apply a time-out:

70+ .

71+ > > timeOut' 1 (reverse [1..5])

72+ > Value [5,4,3,2,1]

73+ .

74+ > > timeOut' 1 (reverse [1..])

75+ > NonTermination

76+ .

77+ The time-out functionality can be used to treat \"slow\" computations as

78+ bottoms:

79+ .

80+ @

81+ \> let tweak = Tweak &#x7b; approxDepth = Just 5, timeOutLimit = Just 2 &#x7d;

82+ \> semanticEq tweak (reverse [1..], [1..]) (bottom :: [Int], [1..] :: [Int])

83+ True

84+ @

85+ .

86+ @

87+ \> let tweak = noTweak &#x7b; timeOutLimit = Just 2 &#x7d;

88+ \> semanticJoin tweak (reverse [1..], True) ([] :: [Int], bottom)

89+ Just ([],True)

90+ @

91+ .

92+ This can of course be dangerous:

93+ .

94+ @

95+ \> let tweak = noTweak &#x7b; timeOutLimit = Just 0 &#x7d;

96+ \> semanticEq tweak (reverse [1..100000000]) (bottom :: [Integer])

97+ True

98+ @

99+ .

100+ Timeouts can also be applied to @IO@ computations:

101+ .

102+ > > let primes () = unfoldr (\(x:xs) -> Just (x, filter ((/= 0) . (`mod` x)) xs)) [2..]

103+ > > timeOutMicro 100 (print $ primes ())

104+ > [2,NonTermination

105+ > > timeOutMicro 10000 (print $ take 10 $ primes ())

106+ > [2,3,5,7,11,13,17,19,23,29]

107+ > Value ()

108+ .

109+ For the underlying theory and a larger example involving use of

110+ QuickCheck, see the article \"Chasing Bottoms, A Case Study in Program

111+ Verification in the Presence of Partial and Infinite Values\"

112+ (<http://www.cse.chalmers.se/~nad/publications/danielsson-jansson-mpc2004.html>).

113+ .

114+ The code has been tested using GHC. Most parts can probably be

115+ ported to other Haskell compilers, but this would require some work.

116+ The @TimeOut@ functions require preemptive scheduling, and most of

117+ the rest requires @Data.Generics@; @isBottom@ only requires

118+ exceptions, though.

10+Synopsis: System clipboard interface.

11+Bug-reports: https://github.com/Daniel-Diaz/Clipboard/issues

12+Description:

13+ /Clipboard/ is a library for easily interfacing with the system clipboard with additional unicode support.

14+ Currently, only in a Windows or GNU/Linux (X11) system.

15+ .

16+ For example, if you type:

17+ .

18+ > $ setClipboardString "Hello, World!"

19+ .

20+ Then you have @\"Hello, World!\"@ available to be pasted wherever you want.

21+ .

22+ Now, if you type:

23+ .

24+ > $ modifyClipboardString reverse

25+ .

26+ You will have @\"!dlroW ,olleH\"@ in your clipboard. So:

27+ .

28+ > $ getClipboardString

29+ > "!dlroW ,olleH"

30+ .

31+ The X11 version depends on the @X11@ package, so you will need the X11 development library

32+ available on your system at compile time. You can install it by @sudo apt-get install libxrandr-dev@

33+ (or the equivalent on your system).

14+

15+-- A longer description of the package.

16+Description:

17+ GenericPretty is a Haskell library that supports automatic

18+ derivation of pretty printing functions on user defined data

19+ types.

20+ .

21+ The form of generics used is based on that introduced in the paper:

22+ Magalhaes, Dijkstra, Jeuring, and Loh,

23+ A Generic Deriving Mechanism for Haskell,

24+ 3'rd ACM Symposium on Haskell, pp. 37-48, September 2010,

25+ <http://dx.doi.org/10.1145/1863523.1863529>.

26+ Changes from the original paper in the GHC implementation

27+ are described here:

28+ <http://www.haskell.org/haskellwiki/GHC.Generics#Changes_from_the_paper>.

29+ .

30+ This package requires the use of the new GHC.Generics features

31+ <http://www.haskell.org/haskellwiki/GHC.Generics>, present from GHC 7.2.

32+ Use of these features is indicated by the DeriveGeneric pragma

33+ or the flag -XDeriveGeneric.

34+ .

35+ Pretty printing produces values of type Text.PrettyPrint.Doc, using

36+ the Text.PrettyPrint library

37+ <http://www.haskell.org/ghc/docs/latest/html/libraries/pretty-1.1.1.0/Text-PrettyPrint.html>.

38+ .

39+ The output provided is a pretty printed version of that provided by

40+ Prelude.show. That is, rendering the document provided by this pretty

41+ printer yields an output identical to that of Prelude.show, except

42+ for extra whitespace.

43+ .

44+ For information about the functions exported by the package please see

45+ the API linked further down this page.

46+

47+ For examples of usage, both basic and more complex see the README file and

48+ the haskell source code files in the TestSuite folder, both included in the package.

10+Synopsis: The Haskell Test Framework

11+Homepage: https://github.com/skogsbaer/HTF/

12+Bug-Reports: https://github.com/skogsbaer/HTF/issues

13+Description:

14+

15+ The Haskell Test Framework (/HTF/ for short) lets you define unit

16+ tests (<http://hunit.sourceforge.net>), QuickCheck properties

17+ (<http://www.cs.chalmers.se/~rjmh/QuickCheck/>), and black box

18+ tests in an easy and convenient way. HTF uses a custom

19+ preprocessor that collects test definitions automatically.

20+ Furthermore, the preprocessor allows HTF to report failing

21+ test cases with exact file name and line number information.

22+ Additionally, HTF tries to produce highly readable output

23+ for failing tests: for example, it colors and pretty prints expected and

24+ actual results and provides a diff between the two values.

25+

26+ .

27+

28+ The documentation of the "Test.Framework.Tutorial" module

29+ provides a tutorial for HTF. There is also a slightly out-dated

30+ blog article (<http://factisresearch.blogspot.de/2011/10/new-version-of-htf-with-diffs-colors.html>)

31+ demonstrating HTF's coloring, pretty-printing and diff functionality.

9+Homepage: https://github.com/haskell/HTTP

10+Category: Network

11+Synopsis: A library for client-side HTTP

12+Description:

13+

14+ The HTTP package supports client-side web programming in Haskell. It lets you set up

15+ HTTP connections, transmitting requests and processing the responses coming back, all

16+ from within the comforts of Haskell. It's dependent on the network package to operate,

17+ but other than that, the implementation is all written in Haskell.

18+ .

19+ A basic API for issuing single HTTP requests + receiving responses is provided. On top

20+ of that, a session-level abstraction is also on offer (the @BrowserAction@ monad);

21+ it taking care of handling the management of persistent connections, proxies,

22+ state (cookies) and authentication credentials required to handle multi-step

23+ interactions with a web server.

24+ .

25+ The representation of the bytes flowing across is extensible via the use of a type class,

26+ letting you pick the representation of requests and responses that best fits your use.

27+ Some pre-packaged, common instances are provided for you (@ByteString@, @String@).

28+ .

29+ Here's an example use:

30+ .

31+ >

32+ > do

33+ > rsp <- Network.HTTP.simpleHTTP (getRequest "http://www.haskell.org/")

34+ > -- fetch document and return it (as a 'String'.)

35+ > fmap (take 100) (getResponseBody rsp)

36+ >

37+ > do

38+ > (_, rsp)

39+ > <- Network.Browser.browse $ do

40+ > setAllowRedirects True -- handle HTTP redirects

41+ > request $ getRequest "http://www.haskell.org/"

42+ > return (take 100 (rspBody rsp))

43+ .

44+ __Note:__ This package does not support HTTPS connections.

45+ If you need HTTPS, take a look at the following packages:

46+ .

47+ * <http://hackage.haskell.org/package/http-streams http-streams>

48+ .

49+ * <http://hackage.haskell.org/package/http-client http-client> (in combination with

50+ <http://hackage.haskell.org/package/http-client-tls http-client-tls>)

14+Synopsis: Automatic testing of Haskell programs

15+Description:

16+ QuickCheck is a library for random testing of program properties.

17+ .

18+ The programmer provides a specification of the program, in the form of

19+ properties which functions should satisfy, and QuickCheck then tests that the

20+ properties hold in a large number of randomly generated cases.

21+ .

22+ Specifications are expressed in Haskell, using combinators defined in the

23+ QuickCheck library. QuickCheck provides combinators to define properties,

24+ observe the distribution of test data, and define test data generators.

25+ .

26+ The <http://www.cse.chalmers.se/~rjmh/QuickCheck/manual.html official QuickCheck manual>

27+ explains how to write generators and properties;

28+ it is out-of-date in some details but still full of useful advice.

29+ .

30+ A user of QuickCheck has written an unofficial, but detailed, tutorial which

31+ you can find at

32+ <https://begriffs.com/posts/2017-01-14-design-use-quickcheck.html>.

1+Name: ReadArgs

2+Version: 1.2.3

3+Synopsis: Simple command line argument parsing

4+

5+Description:

6+

7+ ReadArgs provides the @readArgs@ IO action, which lets you tell the compiler

8+ to parse the command line arguments to fit the type signature you give.

9+ .

10+ For example @(a :: Int, b :: String, c :: Float) <- readArgs@ would

11+ parse the first runtime argument as an @Int@, the second as a @String@ (no

12+ quotes required) and the third as a @Float@.

13+ .

14+ If the runtime arguments are incompatible with the type signature,

15+ then a simple usage statement is given of the types needed.

16+ .

17+ Continuing the previous example, if it was used in a

18+ program named @Example@, the error message for the above

19+ action would be:

20+ .

21+ @

22+ usage: Example Int String Float

23+ @

24+ .

25+ Any type that has both @Typeable@ and @Read@ instances

26+ can be used. @Char@, @String@, and @Text@ are handled specially so that

27+ command line arguments for both do not require quotes (as their

28+ @Read@ instances do). A special instance is provided for @FilePath@ so

29+ that no constructor or quotes are required.

30+ .

31+ @readArgs@ also supports optional arguments and variadic arguments.

32+ Optional arguments are specified using @Maybe@, and variadic arguments

33+ using a list. @(a :: Int, b :: Maybe String, c :: [Float]) <- readArgs@

34+ would successfully parse any of the following sets of command line arguments:

35+ .

36+ @

37+ Example 1

38+ Example 1 2 3 4

39+ Example 1 foo

40+ Example 1 foo 2 3 4

41+ @

42+ .

43+ But not

44+ .

45+ @

46+ Example

47+ Example foo

48+ Example 1.0

49+ @

50+ .

51+ Usage statements for optional and variadic arguments use command-line

52+ parlance:

53+ .

54+ @

55+ usage: Example Int [String] [Float..]

56+ @

57+ .

58+ Note that both optional and variadic parsers are greedy by default

59+ (so @Example 1 2 3 4@ was parsed as @(1, "2", [3.0,4.0])@. They

60+ may both be made non-greedy through use of the @NonGreedy@ constructor:

61+ .

62+ @

63+ ( a :: Int

64+ , NonGreedy b :: NonGreedy Maybe String

65+ , NonGreedy c :: NonGreedy [] Float

66+ ) <- readArgs

7+Synopsis: An embedded language for accelerated array processing

8+

9+Description:

10+ @Data.Array.Accelerate@ defines an embedded array language for computations

11+ for high-performance computing in Haskell. Computations on multi-dimensional,

12+ regular arrays are expressed in the form of parameterised collective

13+ operations, such as maps, reductions, and permutations. These computations may

14+ then be online compiled and executed on a range of architectures.

15+ .

16+ [/A simple example/]

17+ .

18+ As a simple example, consider the computation of a dot product of two vectors

19+ of floating point numbers:

20+ .

21+ > dotp :: Acc (Vector Float) -> Acc (Vector Float) -> Acc (Scalar Float)

22+ > dotp xs ys = fold (+) 0 (zipWith (*) xs ys)

23+ .

24+ Except for the type, this code is almost the same as the corresponding Haskell

25+ code on lists of floats. The types indicate that the computation may be

26+ online-compiled for performance - for example, using

27+ @Data.Array.Accelerate.LLVM.PTX@ it may be on-the-fly off-loaded to the GPU.

28+ .

29+ [/Additional components/]

30+ .

31+ The following supported add-ons are available as separate packages. Install

32+ them from Hackage with @cabal install \<package\>@

33+ .

34+ * @accelerate-llvm-native@: Backend supporting parallel execution on

35+ multicore CPUs.

36+ .

37+ * @accelerate-llvm-ptx@: Backend supporting parallel execution on

38+ CUDA-capable NVIDIA GPUs. Requires a GPU with compute capability 2.0 or

39+ greater. See the following table for supported GPUs:

40+ <http://en.wikipedia.org/wiki/CUDA#Supported_GPUs>

41+ .

42+ * @accelerate-examples@: Computational kernels and applications showcasing

43+ the use of Accelerate as well as a regression test suite, supporting

44+ function and performance testing.

45+ .

46+ * @accelerate-io@: Fast conversions between Accelerate arrays and other

47+ array formats (including vector and repa).

48+ .

49+ * @accelerate-fft@: Discrete Fourier transforms, with FFI bindings to

50+ optimised implementations.

51+ .

52+ * @accelerate-bignum@: Fixed-width large integer arithmetic.

53+ .

54+ * @colour-accelerate@: Colour representations in Accelerate (RGB, sRGB, HSV,

55+ and HSL).

56+ .

57+ * @gloss-accelerate@: Generate gloss pictures from Accelerate.

58+ .

59+ * @gloss-raster-accelerate@: Parallel rendering of raster images and

60+ animations.

61+ .

62+ * @lens-accelerate@: Lens operators for Accelerate types.

63+ .

64+ * @linear-accelerate@: Linear vector spaces in Accelerate.

65+ .

66+ * @mwc-random-accelerate@: Generate Accelerate arrays filled with high

67+ quality pseudorandom numbers.

68+ .

69+ [/Examples and documentation/]

70+ .

71+ Haddock documentation is included in the package

72+ .

73+ The @accelerate-examples@ package demonstrates a range of computational

74+ kernels and several complete applications, including:

75+ .

76+ * An implementation of the Canny edge detection algorithm

77+ .

78+ * An interactive Mandelbrot set generator

79+ .

80+ * A particle-based simulation of stable fluid flows

81+ .

82+ * An /n/-body simulation of gravitational attraction between solid particles

83+ .

84+ * An implementation of the PageRank algorithm

85+ .

86+ * A simple interactive ray tracer

87+ .

88+ * A particle based simulation of stable fluid flows

89+ .

90+ * A cellular automata simulation

91+ .

92+ * A \"password recovery\" tool, for dictionary lookup of MD5 hashes

93+ .

94+ @lulesh-accelerate@ is an implementation of the Livermore Unstructured

95+ Lagrangian Explicit Shock Hydrodynamics (LULESH) mini-app. LULESH represents a

96+ typical hydrodynamics code such as ALE3D, but is highly simplified and

97+ hard-coded to solve the Sedov blast problem on an unstructured hexahedron

98+ mesh.

99+ .

100+ [/Mailing list and contacts/]

101+ .

102+ * Mailing list: <accelerate-haskell@googlegroups.com> (discussion of both

103+ use and development welcome).

104+ .

105+ * Sign up for the mailing list here:

106+ <http://groups.google.com/group/accelerate-haskell>

204+Flag ekg

205+ Default: False

206+ Description:

207+ Enable hooks for monitoring the running application using EKG. Implies

208+ @debug@ mode. In order to view the metrics, your application will need to

209+ call @Data.Array.Accelerate.Debug.beginMonitoring@ before running any

210+ Accelerate computations. This will launch the server on the local machine at

211+ port 8000.

212+ .

213+ Alternatively, if you wish to configure the EKG monitoring server you can

214+ initialise it like so:

215+ .

216+ > import Data.Array.Accelerate.Debug

217+ >

218+ > import System.Metrics

219+ > import System.Remote.Monitoring

220+ >

221+ > main :: IO ()

222+ > main = do

223+ > store <- initAccMetrics

224+ > registerGcMetrics store -- optional

225+ >

226+ > server <- forkServerWith store "localhost" 8000

227+ >

228+ > ...

229+ .

230+ Note that, as with any program utilising EKG, in order to collect Haskell GC

231+ statistics, you must either run the program with:

232+ .

233+ > +RTS -T -RTS

234+ .

235+ or compile it with:

236+ .

237+ > -with-rtsopts=-T

238+ .

239+

16+ A JSON pretty-printing library compatible with aeson as well as

19+ The /library/ provides the function "encodePretty". It is a drop-in

20+ replacement for aeson's "encode" function, producing JSON-ByteStrings for

21+ human readers.

22+ .

23+ The /command-line tool/ reads JSON from stdin and writes prettified JSON

24+ to stdout. It also offers a complementary "compact"-mode, essentially the

25+ opposite of pretty-printing. If you specify @-flib-only@ like this

31+ <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Class.html Algebra.Graph.Class>

32+ and

33+ <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-HigherKinded-Class.html Algebra.Graph.HigherKinded.Class>

34+ can be used for polymorphic graph construction and manipulation. Also see

35+ <http://hackage.haskell.org/package/algebraic-graphs/docs/Algebra-Graph-Fold.html Algebra.Graph.Fold>

36+ that defines the Boehm-Berarducci encoding of algebraic graphs and provides additional

37+ flexibility for polymorphic graph manipulation.

38+ .

39+ This is an experimental library and the API will be unstable until version 1.0.0. Please

40+ consider contributing to the on-going

41+ <https://github.com/snowleopard/alga/issues discussions on the library API>.

4+name: app-settings

5+version: 0.2.0.11

6+synopsis: A library to manage application settings (INI file-like)

7+description:

8+ A library to deal with application settings.

9+ .

10+ This library deals with read-write application settings.

11+ You will have to specify the settings that your application

12+ uses, their name, types and default values.

13+ .

14+ Setting types must implement the 'Read' and 'Show' typeclasses.

15+ .

16+ The settings are saved in a file in an INI-like key-value format

17+ (without sections).

18+ .

19+ Reading and updating settings is done in pure code, the IO

20+ monad is only used to load settings and save them to disk.

21+ It is advised for the user to create a module in your project

22+ holding settings handling.

23+ .

24+ You can then declare settings:

25+ .

26+ > fontSize :: Setting Double

27+ > fontSize = Setting "fontSize" 14

28+ >

29+ > dateFormat :: Setting String

30+ > dateFormat = Setting "dateFormat" "%x"

31+ >

32+ > backgroundColor :: Setting (Int, Int, Int)

33+ > backgroundColor = Setting "backcolor" (255, 0, 0)

34+ .

35+ Optionally you can declare the list of all your settings,

36+ in that case the application will also save the default

37+ values in the configuration file, but commented out:

38+ .

39+ > fontSize=16

40+ > # dateFormat="%x"

41+ > # backcolor=(255,0,0)

42+ .

43+ If you do not specify the list of settings, only the

44+ first line would be present in the configuration file.

45+ .

46+ With an ordinary setting, one row in the configuration file

47+ means one setting. That setting may of course be a list

48+ for instance. This setup works very well for shorter lists

49+ like [1,2,3], however if you have a list of more complex

50+ items, you will get very long lines and a configuration

51+ file very difficult to edit by hand.

52+ .

53+ For these special cases there is also the 'ListSetting'

54+ constructor:

55+ .

56+ > testList :: Setting [String]

57+ > testList = ListSetting "testList" ["list1", "list2", "list3"]

58+ .

59+ Now the configuration file looks like that:

60+ .

61+ > testList_1="list1"

62+ > testList_2="list2"

63+ > testList_3="list3"

64+ .

65+ Which is much more handy for big lists. An empty list is represented

66+ like so:

67+ .

68+ > testList=

69+ .

70+ There is also another technique that you can use if you have too long

71+ lines: you can put line breaks in the setting values if you start the

72+ following lines with a leading space, like so:

73+ .

74+ > testList=["list1",

75+ > "list2", "list3"]

76+ .

77+ In that case don't use the ListSetting option. Any character after the

78+ the leading space in the next lines will go in the setting value. Note

79+ that the library will automatically wrap setting values longer than 80

80+ characters when saving.

81+ .

82+ Once we declared the settings, we can read the configuration

83+ from disk (and your settings module should export your wrapper

84+ around the function offered by this library):

85+ .

86+ > readResult <- try $ readSettings (AutoFromAppName "test")

87+ > case readResult of

88+ > Right (conf, GetSetting getSetting) -> do

89+ > let textSize = getSetting fontSize

90+ > saveSettings emptyDefaultConfig (AutoFromAppName "test") conf

91+ > Left (x :: SomeException) -> error "Error reading the config file!"

92+ .

93+ 'AutoFromAppName' specifies where to save the configuration file.

94+ And we've already covered the getSetting in this snippet, see

95+ the 'readSettings' documentation for further information.

96+ .

97+ You can also look at the tests of the library on the github project for sample use.

4+synopsis: Run IO operations asynchronously and wait for their results

5+

6+description:

7+ This package provides a higher-level interface over

8+ threads, in which an @Async a@ is a concurrent

9+ thread that will eventually deliver a value of

10+ type @a@. The package provides ways to create

11+ @Async@ computations, wait for their results, and

12+ cancel them.

13+ .

14+ Using @Async@ is safer than using threads in two

15+ ways:

16+ .

17+ * When waiting for a thread to return a result,

18+ if the thread dies with an exception then the

19+ caller must either re-throw the exception

20+ ('wait') or handle it ('waitCatch'); the

21+ exception cannot be ignored.

22+ .

23+ * The API makes it possible to build a tree of

24+ threads that are automatically killed when

25+ their parent dies (see 'withAsync').

3+Synopsis: Ability to read, write, and modify BBDB files

4+Description: BBDB (http://savannah.nongnu.org/projects/bbdb/) is a

5+ contact management utility that can be used with

6+ emacs. It stores its data internally as a lisp

7+ expression. This module parses the lisp and

8+ provides some convenience functions to get at and

9+ manipulate the data all from within Haskell. See

10+ the hackage docs for usage and examples.

21+ * Jasper Van Der Jeugt has written a tutorial for /blaze-html/,

22+ which is a sister library of /blaze-svg/. It may not be directly relevant,

23+ but still it gives a good overview on how to use the combinators in

24+ "Text.Blaze.Svg11" and "Text.Blaze.Svg11.Attributes":
