32+## Help! Something isn't working

9433

95−To use precompiled binaries you'll need:

34+The #1 problem that people have when using `haskell.nix` is that they find themselves building GHC.

35+This should not happen, but you *must* follow the `haskell.nix` setup instructions properly to avoid it.

36+If you find this happening to you, please check that you have followed the

37+[getting started instructions](https://input-output-hk.github.io/haskell.nix/tutorials/getting-started.html#setting-up-the-binary-cache) and

38+consult the corresponding [troubleshooting section](https://input-output-hk.github.io/haskell.nix/troubleshooting.html#why-am-i-building-ghc).

9639

97−- to configure a binary cache by following instructions on [iohk.cachix.org](https://iohk.cachix.org).

98−- to pin `nixpkgs` according to [nix/sources.json](nix/sources.json).

40+The troubleshooting documentation also contains some help for other common issues.

41+Please give it a read before asking on IRC or opening an issue.

9942

43+If you're still stuck, join the [#haskell.nix](https://www.irccloud.com/invite?channel=%23haskell.nix&hostname=irc.libera.chat&port=6697&ssl=1) channel on [irc.libera.chat](https://libera.chat/), or open an issue.

11This file contains a summary of changes to Haskell.nix and `nix-tools`

22that will impact users.

33

4+## Jul 27, 2022

5+* Removed reliance on `builtins.currentSystem`. It was used it to provide

6+ `pkgs.evalPackages` via an overlay that it used to run derivations

7+ used in imports from derivation (IFDs).

8+

9+ These derivations are now run on `buildPackages` by default.

10+

11+ Passsing `evalPackages` to a project function will change where all the

12+ derivations used in IFDs are run for that project (including shell tools):

13+ evalPackages = import nixpkgs haskellNix.nixpkgsArgs;

14+

15+ Passing `evalSystem` instead will use create a suitable `nixpkgs` using `pkgs.path`

16+ and `pkgs.overlay`:

17+ evalSystem = "x86_64-linux";

18+ or

19+ evalSystem = builtins.currentSystem;

20+

21+ The `haskellLib.cleanGit` function is also affected by this change. If you are cross

22+ compiling and using `cleanGit` you should probably do something like:

23+ pkgs = import nixpkgs haskellNix.nixpkgsArgs;

24+ evalPackages = import nixpkgs (haskellNix.nixpkgsArgs // { system = evalSystem; });

25+ p = pkgs.pkgsCross.mingwW64.haskell-nix.cabalProject {

26+ inherit evalPackages;

27+ src = evalPackages.haskell-nix.haskellLib.cleanGit { src = ./.; };

28+ };

29+

30+## Feb 16, 2022

31+* Removed lookupSha256 argument from project functions.

32+ Pass a `sha256map` instead.

33+* Added better support for `repository` in `cabal.project`. These

34+ blocks should now work without the need for passing `extra-hackages` and

35+ `extra-hackage-tarballs`.

36+

37+## Aug 6, 2021

38+* Included dependencies of haskell.nix that were tracked in `nix/sources.json`

39+ as flake inputs (`flake.lock` replaces `nix/sources.json`).

40+* Uses `flake-compat` to continue to provide a compatible interface for non

41+ flake projects.

42+

43+## Jul 23, 2021

44+* `source-repository-package` references in `cabal.project` files are now

45+ left as a `source-repository-package` when calculating the the `plan-nix` for

46+ `cabalProject` based functions.

47+ This makes haskell.nix match the behaviour of `cabal` better.

48+ Materialized files for projects that use `source-repository-package`

49+ references will need to be updated.

50+* Only planned components are included in a haskell.nix cabal project.

51+ If cabal solver does not include the component in the `plan.json` file it

52+ will not be present in `hsPkgs.pkg.components`.

53+* When the same package occurs more than once in a plan.json file

54+ the latest version is picked by haskell.nix.

55+

56+## Apr 8, 2021

57+* Project arguments are now validated with the Nix module system.

58+ If unexpected argments are passed to a project function this may now

59+ result in an error.

60+

61+## Feb 22, 2021

62+* Add `.dwarf` to build any component with DWARF dubug info on linux

63+ (ghc >=8.10.2).

64+* Pass `enableDWARF` to `shellFor` for to get a shell where all the

65+ components are the `.dwarf` ones.

66+

67+## Feb 18, 2021

68+* `ghcOptions` has been moved from package and is now a list of strings.

69+ old: packages.x.package.ghcOptions = "someGHCoption";

70+ new: packages.x.ghcOptions = ["someGHCoption"];

71+ To specify ghcOptions for all packages:

72+ ghcOptions = ["someGHCoption"];

73+ For a single component:

74+ packages.x.compoents.library.ghcOptions = ["someGHCoption"];

75+

76+## Feb 8, 2021

77+* Removed older versions of haskell-language-server from custom-tools

78+ (0.8.0 is in hackage so we can still get that version).

79+

80+## Jan 14, 2021

81+* Added support for cross package refs (with a project). Relative

82+ directory references between packages within a project should now

83+ work.

84+* Added `includeSiblings` to `cleanSourceWith`. When `true` it

85+ prevents the `subDir` arg from causing filtering of other directories.

86+* Added `keepGitDir` to `cleanGit` to allow `.git` directory to be kept

87+ (useful for components that use the `githash` package).

88+

89+## Nov 26, 2020

90+* Renamed `otherShells` arg for `shellFor` to `inputsFrom

91+

92+## Nov 25, 2020

93+* The `shellFor` `makeConfigFiles` `ghcWithHoogle` and `ghcWithPackages`

94+ functions have been removed from `project.hsPkgs`. Instead access

95+ them from `project` itself (e.g. change `p.hsPkgs.shellFor` to `p.shellFor`).

96+* The reflex-platform like `project.shells.ghc` has been removed.

97+ If needed, add something like `p // { shells.ghc = p.shellFor {} }`

98+ to `shell.nix`.

99+

100+## Nov 24, 2020

101+* Added `${targetPrefix}cabal` wrapper script for running cross

102+ compilers in `shellFor`.

103+* `otherShells` arg added to `shellFor`.

104+

105+## Oct 31, 2020

106+* Passing `tools.hoogle` to `shellFor` with a value suitable for `haskel-nix.tool` will

107+ use the specified `hoogle` inside `shellFor`. This allows for materialization

108+ of `hoogle`.

109+

110+## Oct 28, 2020

111+* Passing `compiler-nix-name` to project functions for `stack.yaml`

112+ based projects now overrides the compiler used (was ignored before).

113+

114+## Sep 8, 2020

115+* Added the ability to generate coverage reports for packages and

116+ projects.

117+* Added the `doCoverage` module option that allows users to choose

118+ packages to enable coverage for.

119+* Added a `doCoverage` flag to the component builder that outputs HPC

120+ information when coverage is enabled.

121+* Added test for coverage.

122+

123+## July 21, 2020

124+* Removed `components.all`, use `symlinkJoin` on components.exes or

125+ `shellFor` if you need a shell.

126+* Added `components` argument to `shellFor`.

127+

128+## July 21, 2020

129+* Added GHC 8.8.4 and replaced 8.8.3 in tests and as the ghc

130+ used to build nix-tools for stack projects.

131+

132+## July 20, 2020

133+* Changed `haskell-nix.roots` and `p.roots` to single derivations.

134+

135+## July 8, 2020

136+* Removed `sources.nixpkgs-default`, use `sources.nixpkgs` instead.

137+* Removed `./nixpkgs` directory, use `(import ./. {}).sources`

138+ or `./nix/sources.nix` instead.

139+* Removes V1 interface for details on how to fix old code see:

140+ https://github.com/input-output-hk/haskell.nix/issues/709

141+* Removed defaultCompilerNixName.

142+* cabalProject, cabalProject', hackage-project and hackage-package

143+ now require a `compiler-nix-name` argument.

144+* `haskell-nix.tool` and `.tools` now require a `compiler-nix-name` argument.

145+ New functions `p.tool` and `p.tools` (where p is a project) do not.

146+ Like `shellFor { tools = ... }` they will use the compiler nix name

147+ from the project (including stack projects where it is derived from

148+ the resolver).

149+* `haskell-nix.alex` and `haskell-nix.happy` have been removed. Use

150+ `p.tool "alex" "3.2.5"` or `shellFor { tools = { alex = "3.2.5"; } }`.

151+* `haskell-nix.nix-tools` -> `haskell-nix.nix-tools.ghc883` (it includes

152+ the hpack exe now).

153+* `haskell-nix.cabal-install` ->

154+ `p.tool "cabal" "3.2.0.0"` or `shellFor { tools = { cabal = "3.2.0.0"; } }`

155+* `haskell-nix.haskellNixRoots` -> `haskell-nix.roots ghc883` or `p.roots`

156+

157+## June 25, 2020

158+* Haddock docs are now built in their own derivation when needed (not as part

159+ of the component build).

160+ They should build automatically when something (such as `shellFor`) attempts

161+ to accesses the `.doc` attribute of component.

162+

4163## December 27, 2019

5164* Fix overlays/bootstrap.nix to provide LLVM 6, not LLVM 5, to ghc-8.6.X compilers.

1+# Developer Coverage Overview

2+

3+## Building

4+

5+The implementation of coverage starts with the "doCoverage" flag on

6+the builder in `comp-builder.nix`. The doCoverage flag enables and

7+disables the Cabal coverage flag and copies any generated coverage

8+data to "$out/share/hpc".

9+

10+### Mix and tix files

11+

12+The coverage information for any derivation consists of "mix" and

13+"tix" files.

14+

15+Mix files record static information about a source file and are

16+generated at build time. They primarily contain a path to the source

17+file and information about expressions and regions of the source file,

18+which are later referenced by tix files.

19+

20+Tix files contain dynamic information about a test run, recording when

21+a portion of a source file is touched by a test. These are generated

22+when the test is run.

23+

24+### Multiple local packages

25+

26+In the context of multiple local packages, there are a few types of

27+coverage we might be interested in:

28+ - How well does the tests for this package cover the package library?

29+ - How well does the tests for this package cover the libraries of

30+ other packages in this project?

31+ - Both of the above.

32+

33+To facilitate expressing any of these classifications of coverage, the

34+`lib/cover.nix` function provides the `mixLibraries` argument. If

35+you're just interested in how the tests cover the package library, you

36+provide that library as an argument to `mixLibraries`. If you're

37+interested in how the tests also cover other local packages in the

38+project, you can also provide those libraries as arguments to

39+mixLibraries.

40+

41+The `projectCoverageReport` and `coverageReport` attributes that are

42+provided by default on projects and packages respectively provide

43+coverage information for *all* local packages in the project. This is

44+to mimic the behaviour of Stack, which seems to be the expectation of

45+most people. Of course, you can use the `projectCoverageReport` and

46+`coverageReport` functions to construct your own custom coverage

47+reports (as detailed in the [coverage tutorial](../tutorials/coverage.md#custom)).

48+

49+## Coverage reports

109+This file contains the stackage resolver, as well as set of extra

110+packages. The extras specifies which `extra-deps` (here:

112+local packages we want (here: `my-package`).

113+

114+## Using Cabal

115+

116+### Generating `plan.json`

117+

118+To get a plan, you need Cabal and GHC. See the [How to install a

119+compiler section of the Nixpkgs Manual][compiler] for information

120+about how to choose a specific compiler version.

121+

122+[compiler]: https://nixos.org/nixpkgs/manual/#how-to-install-a-compiler

123+

124+!!! note "Cabal version"

125+ The minimum Cabal version is 2.4. This version is available

126+ in the NixOS 19.03 release.

127+

128+For this example, we will run a `nix-shell` with the default GHC

129+version for Nixpkgs.

130+

131+```bash

132+nix-shell -p haskellPackages.cabal-install haskellPackages.ghc \

133+ --run "cabal new-configure"

134+```

135+

136+If all goes well, you should now have the file

137+`dist-newstyle/cache/plan.json`.

138+

139+!!! tip "Specifying the GHC version"

140+ To use a specific compiler version, replace `haskellPackages.ghc`

141+ with something like `haskell-nix.compiler.ghc865`. The given compiler

142+ must exist in your Nixpkgs version, of course. See also the

143+ [Nixpkgs Manual][compiler].

144+

145+### Using `plan-to-nix`

146+

147+With [nix-tools installed](./installing-nix-tools.md), we can then run the

148+following command on a Cabal project and its build plan. Omit the

149+`--cabal-project` option if you don't have a project file.

150+

151+```bash

152+# convert the plan.json file into a pkgs.nix file

153+plan-to-nix --output . \

154+ --plan-json dist-newstyle/cache/plan.json

155+ --cabal-project cabal.project

156+```

157+

158+This will produce a `pkgs.nix` file that looks like the following:

159+

160+```nix

161+{

162+ pkgs = hackage:

163+ {

172+ { packages = { my-package = ./.plan.nix/my-package.nix; }; };

173+}

174+```

175+

176+It has converted Cabal's build plan into a Nix expression that selects

177+dependencies from `hackage.nix`. All local packages in the project are

1+# Supported GHC Versions

2+

3+The following GHC versions are defined in `haskell.nix` (there is a derivation

4+for each, though not all are cached or tested by CI):

5+- 8.4.4

6+- 8.6.{1,2,3,4,5}

7+- 8.8.{1,2,3,4}

8+- 8.10.{1,2,3,4,5}

9+- 9.0.1

10+- 9.2.1

11+- 9.2.2

12+

13+The following table shows the Nixpkgs/GHC versions which are built/cached, and

14+which of those are further tested. If you use a combination of Nixpkgs version

15+and GHC version which is in this table, you should hit our cache, saving

16+considering time by not building GHC and a few additional tools.

17+

18+Note that if you try to use `haskell.nix` as an overlay over Nixpkgs from a

19+standard Nixpkgs channel you will likely get a cache miss. To hit our cache you

20+really should use an instance of Nixpkgs provided by `haskell.nix` itself.

21+

1+# Troubleshooting

2+

3+## Issues with building and garbage-collection

4+

5+### Why am I building GHC?

6+

7+It's easier to list the reverse: when will you *not* build GHC?

8+

9+- You have configured the [binary cache](tutorials/getting-started.md) correctly.

10+- You are using one of the GHC versions which [we support](reference/supported-ghc-versions.md).

11+- You are using one of the nixpkgs versions used by our CI (you can access the sources for these [through haskell.nix](tutorials/getting-started.md).

12+

13+If you think you are doing all of these and you still find you're building GHC, drop us a line.

14+

15+### Why am I building lots of Haskell packages?

16+

17+We don't generally cache much of Hackage (there's a lot of it!), except for the parts which are used by our tests.

18+So this is expected, unfortunately.

19+

20+### How do I prevent the evaluation-time dependencies of my project from being garbage-collected?

21+

22+The `haskell-nix.roots "ghc884"` should include all the evaluation-time dependencies

23+and the main build time dependencies of a project using ghc 8.8.4.

24+So you can add that to the relevant GC root.

25+In practice, if you're using a CI system like Hydra/Hercules, this means adding it to a job in `release.nix`/`ci.nix`.

26+

27+## General troubleshooting when using `cabalProject`/`stackProject`/`project`

28+

29+### Does the cabal/stack build work?

30+

31+In `haskell.nix`, we strive to take the build configuration from the cabal/stack configuration files.

32+So if you have a problem with your cabal/stack configuration, it is likely that you will have a problem with the `haskell.nix` build too.

33+

34+So the first thing to do is make sure that the build works with `cabal` or `stack` as normal.

35+If it *does* work, then the `haskell.nix` one should as well.

36+If, on the other hand, there is a failure, the `cabal` or `stack` build is usually easier to debug (or at least it is no longer a `haskell.nix` problem).

37+

38+### Is the `haskell.nix` configuration completely in line with the cabal/stack configuration?

39+

40+The `haskell.nix` configuration can come apart from the cabal/stack configuration in a number of ways:

41+

42+#### Compiler version

43+

44+(Cabal users only. For stack users this comes from the snapshot, so stack and `haskell.nix` will agree.)

45+

46+The compiler version used by `haskell.nix` is selected by the `compiler-nix-name` argument; or if you do not specify it, by some default version (we recommend specifying it!).

47+Cabal does not provide an easy way to pin a *version* of the compiler (`with-compiler` lets you pick a particular executable, which is nearly but not quite what we want).

48+Hence, the two can come apart.

49+

50+Make sure you are using the same compiler for the cabal build as for the `haskell.nix` build.

51+

52+#### Hackage index state

53+

54+(Cabal users only. For stack users, package versions come from the snapshot, so stack and `haskell.nix` will agree.)

55+

56+Cabal has the concept of the Hackage "index state".

57+This is a timestamp, and it tells Cabal to behave "as if" it was seeing Hackage at that point in time.

58+Pinning it is generally good for reproducibility regardless of whether you use `haskell.nix` (you can do so in `cabal.project`).

59+

60+If you do not set an `index-state` in `cabal.project`, then Cabal will use the latest one based on when you last called `cabal update`, and `haskell.nix` will use the latest one it knows about from `hackage.nix`.

61+These may not be the same!

62+So if you use `haskell.nix` we strongly recommend pinning the `index-state`.

63+

64+#### Nix-only configuration options

65+

66+You can set configuration options in your Nix code that are not present in the cabal/stack configuration.

67+For example, you might enable profiling.

68+

69+Where possible, try to do the configuration in your cabal/stack configuration, e.g. setting `profiling: true` in `cabal.project`.

70+This will ensure that the two builds agree.

71+

72+If you want or need to set some of them in Nix, try bringing the two into sync temporarily for troubleshooting.

73+

74+## Other specific issues

75+

76+### Why does the build complain about some files being missing?

77+

78+Sometimes your build works fine outside `haskell.nix`, but inside the `haskell.nix` build, cabal complains that some file is missing.

79+What is going on?

80+

81+The answer is that `haskell.nix` *thoroughly* cleans the source *by following what is mentioned as required in the cabal file*.

82+So we only include Haskell sources if they appear in a `hs-source-dirs` somewhere; and we only include non-Haskell files if they are included in `extra-source-files` or similar.

83+

84+This is good practice anyway: if you do not include such files in `extra-source-files` then they will not be included in `cabal sdist`, which will cause problems if you ever upload your package to Hackage.

85+But `haskell.nix` is very picky about it.

86+

87+### Why does my executable depend on GHC/GCC?

88+

89+You may want to set the `dontStrip` option to `false` (see https://github.com/input-output-hk/haskell.nix/issues/829).

90+This is not set by default because it can occasionally cause breakage.

1+# Content addressed derivations

2+## Introduction

3+

4+Floating content addressed derivations (from now *CA derivations*) is an experimental feature which substantially change how the hashes in the store paths are calculated.

5+Indeed, normally derivations are input addressed i.e. the outputs store paths depends only on the derivation inputs, instead with CA derivations they depend on the content of the outputs.

6+

7+This has two main advantages:

8+

9+- The so-called "early cutoff", namely the ability of Nix to stop a build if the build outputs would be something already built.

10+For example suppose you add a comment in an Haskell source, at this point Nix will rebuild the component depending on this source but since the output will be the same (adding a comment is an "output-invariant" change for `ghc`) every other component that depends on that will not be rebuilt.

11+- Users of the same Nix store does not need to trust each other when using substituters.

12+

13+You can find more information in the [ca-derivations page on the wiki](https://nixos.wiki/wiki/Ca-derivations) (and in the other resources linked there).

14+

15+## Usage

16+### Enable CA derivations in your system

17+First of all your Nix installation must support the `ca-derivations` experimental feature, this can done by adding the following in your `nix.conf`:

18+

19+```

20+experimental-features = ca-derivations

21+```

22+

23+Or if you use NixOS:

24+```

25+nix.extraOptions = ''

26+ experimental-features = ca-derivations

27+'';

28+```

29+

30+## Enable CA derivations in your project

31+At this point you can pass a new module to `project'` that tells `haskell.nix` to build every component in the project as CA derivation.

32+

33+```

34+haskell-nix.project' {

35+ # ...

36+

37+ modules = [{

38+ contentAddressed = true;

39+ # packages.project-name.components.exes.executable.contentAddressed = true;

40+ }];

41+};

42+```

43+

44+Optionally you can also specify which components you don't want to be content addressed.

45+

46+## Known problems

47+### Limitation of the current CA derivations implementation

48+

49+As explained in the [RFC 62](https://github.com/tweag/rfcs/blob/cas-rfc/rfcs/0062-content-addressed-paths.md)

50+

51+> The current implementation has a naive approach that just forbids fetching a path if the local system has a different realisation for the same drv output. This approach is simple and correct, but it's possible that it might not be good-enough in practice as it can result in a totally useless binary cache in some pathological cases.

52+

53+For example, suppose that your machine builds a derivation `A` producing an output `A.out` in your store and that after that a CI machine builds the same derivation `A` but producing a different output `A.out'` and populating a cache with this output.

54+At this point, if you need to build a derivation `B` that depends on `A`, since you already have the realisation `A.out` in your local store and you can't get `B.out` from the cache and you will end up building `B` even if one of its realisation is in the cache.

55+

56+This means that, in some cases, enabling CA derivations would lead to more rebuilds than not having it.

57+

58+### Hydra

59+Hydra currently doesn't support CA derivations, efforts are being made in this direction.

60+

61+

62+### GHC is not deterministic

63+Currently `ghc` is determinstic only disabling the parallel building i.e. passing `-j1`. [Here](https://gitlab.haskell.org/ghc/ghc/-/issues/12935) the upstream issue.

64+

65+Having a deterministic `ghc` would be a dream since it will automatically fix all the pathological cases about substituters discussed above and would allow `haskell.nix` to parallel build even when using CA derivations.

13+IMPORTANT: you *must* do this or you *will* build several copies of GHC!

14+

15+You can configure Nix to use our binary cache, which is pushed to by CI, so should contain the artifacts that you need.

16+

17+You need to add the following sections to `/etc/nix/nix.conf` or, if you are a trusted user, `~/.config/nix/nix.conf` (if you don't know what a "trusted user" is, you probably want to do the former).

18+

19+```

21+substituters = [...] https://cache.iog.io [...]

22+```

23+

24+If you're running NixOS, you need to add/update the following in your `/etc/nixos/configuration.nix` files instead.

25+

26+```

27+# Binary Cache for Haskell.nix

28+nix.settings.trusted-public-keys = [

50+## Niv

51+

52+[Niv](https://github.com/nmattia/niv) is a command line tool for keeping track of Nix project dependencies.

53+

54+This guide assumes that the `sources.haskellNix` will be set to point

55+a pinned copy of the haskell.nix github repo. One easy way to do this

56+is to use Niv. If you prefer not to use Niv another option is described

57+in the in the "Using haskell.nix without niv" section of this document.

58+

59+If you want to use Nix Flakes to pin your dependencies then you should

60+consider following the [Getting started with flakes](./getting-started-flakes.md)

61+document instead of this one.

62+

63+After installing niv you can initialize niv and pin the latest haskell.nix

64+commit by running the following in the root directory of the project:

65+

66+```

67+niv init

68+niv add input-output-hk/haskell.nix -n haskellNix

69+```

70+

71+Then when you want to update to the latest version of haskellNix use:

72+

73+```

74+niv update haskellNix

75+```

76+

77+## Scaffolding

78+

79+The following work with `stack.yaml` and `cabal.project` based

80+projects.

81+

82+Add `default.nix`:

83+

84+```nix

85+let

86+ # Read in the Niv sources

87+ sources = import ./nix/sources.nix {};

88+ # If ./nix/sources.nix file is not found run:

90+ # niv add input-output-hk/haskell.nix -n haskellNix

91+

92+ # Fetch the haskell.nix commit we have pinned with Niv

93+ haskellNix = import sources.haskellNix {};

94+ # If haskellNix is not found run:

95+ # niv add input-output-hk/haskell.nix -n haskellNix

98+ pkgs = import

99+ # haskell.nix provides access to the nixpkgs pins which are used by our CI,

100+ # hence you will be more likely to get cache hits when using these.

101+ # But you can also just use your own, e.g. '<nixpkgs>'.

102+ haskellNix.sources.nixpkgs-unstable

103+ # These arguments passed to nixpkgs, include some patches and also

104+ # the haskell.nix functionality itself as an overlay.

110+ src = ./.;

111+ };

112+ # Specify the GHC version to use.

113+ compiler-nix-name = "ghc8102"; # Not required for `stack.yaml` based projects.

114+}

115+```

116+

117+!!! note "git dependencies"

118+ If you have git dependencies in your project, you'll need

119+ to [calculate sha256 hashes for them](./source-repository-hashes.md).

120+

121+### Working with a project

122+

123+Top-level attributes are Haskell packages (incl. dependencies) part of your project.

124+

125+To build the library component of a package in the project run:

126+

127+```shell

128+nix-build -A your-package-name.components.library

129+```

130+

131+There are also other components such as `exes`, `tests`, `benchmarks` and `all`.

132+To build an executable:

133+

134+```shell

135+nix-build -A your-package-name.components.exes.your-exe-name

137+

138+To cross compile use the `projectCross` attribute:

143+```

144+

145+To open a shell for use with `cabal`, `hlint` and `haskell-language-server` add `shell.nix`:

146+

147+```nix

148+(import ./default.nix).shellFor {

149+ tools = {

155+```

156+

164+

165+To open a shell for use with `stack` see [the following issue](https://github.com/input-output-hk/haskell.nix/issues/689#issuecomment-643832619).

166+

167+## Using haskell.nix without Niv

168+

169+If you would prefer not to use niv you can replace

170+`sources = import ./nix/sources.nix {};` in the examples with:

171+

172+```nix

173+let sources = {

174+ haskellNix = builtins.fetchTarball "https://github.com/input-output-hk/haskell.nix/archive/master.tar.gz";

176+```

177+

178+The `fetchTarball` call above will always get the latest version, and is

179+similar to an auto-updating Nix channel.

180+

181+However, in your own project, you may wish to pin [haskell.nix][] (as

182+you would pin Nixpkgs). This will make your builds reproducible, more

183+predictable, and faster (because the fixed version is cached).

184+

185+Straightforward way of doing this is to change the branch name to a revision.

186+

187+```nix

188+let sources = {

189+ haskellNix = builtins.fetchTarball "https://github.com/input-output-hk/haskell.nix/archive/f1a94a4c82a2ab999a67c3b84269da78d89f0075.tar.gz";

192+

193+There are other possible schemes for pinning. See

1+# Bumping Hackage and Stackage snapshots

2+

3+`haskell.nix` relies on some generated data providing information about packages in Hackage and Stackage snapshots.

4+These are kept in [`hackage.nix`](https://github.com/input-output-hk/hackage.nix) and [`stackage.nix`](https://github.com/input-output-hk/stackage.nix) respectively.

5+If your project depends on a Hackage package, then the `hackage.nix` revision used must be new enough to contain that, and likewise for Stackage snaphots and `stackage.nix`.

6+

7+## Updating and pinning `hackage.nix` and `stackage.nix`

8+

9+`haskell.nix` pins particular revisions of these repositories internally, both for our own usage in testing, and so that users have a sensible default when getting started.

10+These revisions are updated nightly, so you can get newer revisions of `hackage.nix` and `stackage.nix` by updating your revision of `haskell.nix` itself.

11+

12+However, this exposes you to changes in `haskell.nix` which you may not want, such as changes that force compiler rebuilds, or the occasional bug.

13+Instead, you can pin `hackage.nix` and `stackage.nix` independently. For example:

14+

15+```nix

16+let

17+ # You can use a tool like `niv` to manage this boilerplate

18+ hackageSrc = builtins.fetchTarball https://github.com/input-output-hk/hackage.nix/archive/master.tar.gz;

19+ stackageSrc = builtins.fetchTarball https://github.com/input-output-hk/stackage.nix/archive/master.tar.gz;

20+ haskellSrc = builtins.fetchTarball https://github.com/input-output-hk/haskell.nix/archive/master.tar.gz;

21+

22+ haskellNix = import haskellSrc {

23+ # This allows you to override the pins used by `haskell.nix` internally

24+ sourcesOverride = {

25+ hackage = hackageSrc;

26+ stackage = stackageSrc;

27+ };

28+ };

29+in ...

30+```

31+

32+This way you can change the revisions of `hackage.nix` and `stackage.nix`

33+without changing `haskell.nix`.

34+

35+However, bear in mind that Stackage refers to Hackage, so your Stackage pin

36+should never be newer than your Hackage pin.

1+# Materialization

2+

3+## What is materialization?

4+

5+Capturing and storing the Nix files for a project so that they do

6+not need to be built (or checked). This allows us to cache the input

7+of an IFD (import from derivation).

8+

9+## Why use materialization?

10+

11+Using functions like `project`, `cabalProject`, `stackProject`

12+and `hackage-package` results in a lot of dependencies (all the

13+dependencies of nix-tools for instance).

14+

15+* They can be slow to calculate (even if no work needs to be done it

16+ is not unusual for it to take 5 seconds per project).

17+

18+* They can be slow to build (or download) on machines that do not

19+ yet have them in the Nix store.

20+

21+* Hydra does not show progress because it does not provide feedback until it

22+ has a list of jobs and the list of jobs cannot depend on the Nix expressions

23+ being present (although this is often blamed on IFD it would be the same if

24+ it wrote out JSON files and read them in)

25+

26+## When is it OK to materialize?

27+

28+* The Nix expressions are unlikely to change frequently (and when it does you

29+ are happy to manually update it).

30+

31+* You are happy to script something to update the materialized Nix files

32+ automatically.

33+

34+* You are certain that the IFD you materialize is not `system`-dependent. If it

35+ was you'd obtain different Nix expressions depending on which `system` the

36+ IFD was evaluated.

37+

38+## How can we materialize the Nix files?

39+

40+Lets say we want to build `hlint`. We might start with an `hlint.nix`

41+file that looks like this:

42+

43+```nix

44+let inherit (import ./. {}) sources nixpkgsArgs;

45+ pkgs = import sources.nixpkgs nixpkgsArgs;

46+ hlint = pkgs.haskell-nix.hackage-package {

47+ compiler-nix-name = "ghc8102";

48+ name = "hlint";

49+ version = "2.2.11";

50+ };

51+in hlint

52+```

53+

54+Building this may result in a lot of output, but if you build

55+it again it should give just:

56+

57+```

58+$ nix-build hlint.nix -A components.exes.hlint

61+```

62+

63+To materialize the Nix files we need to take care to pin down the inputs. Stack

64+projects have their inputs pinned through specifying the snapshot. For cabal

65+projects this means we must specify the `index-state` of hackage we want to

66+use:

67+

68+```nix

69+let inherit (import ./. {}) sources nixpkgsArgs;

70+ pkgs = import sources.nixpkgs nixpkgsArgs;

78+```

79+

116+have the dependencies in their store will have to wait while they are built or

117+downloaded.

1+# Mapping non-Haskell dependencies to Nixpkgs

2+

3+Cabal files may contain dependencies to external non-Haskell

4+dependencies via:

5+

6+* [`build-tool-depends`](https://cabal.readthedocs.io/en/latest/cabal-package.html#pkg-field-build-tool-depends)

7+* [`pkgconfig-depends`](https://cabal.readthedocs.io/en/latest/cabal-package.html#pkg-field-pkgconfig-depends)

8+* [`frameworks`](https://cabal.readthedocs.io/en/latest/cabal-package.html#pkg-field-frameworks)

9+* [`extra-libraries`](https://cabal.readthedocs.io/en/latest/cabal-package.html#pkg-field-extra-libraries)

10+

11+If there is a `pkgs` attribute in Nixpkgs that matches the name given

12+in the Cabal file, then it will be added as a dependency (see the

13+output of `cabal-to-nix`). Otherwise, there needs to be a mapping from

14+Cabal file names (decided by the package author) to Nix package

15+identifiers.

16+

17+### Nixpkgs overlay

18+

19+The user may solve it by themself by overriding Nixpkgs and adding a

20+package alias. For example:

21+

22+```nix

23+nixpkgs.overlays = [

24+ (self: super: {

25+ icuuc = self.icu;

26+ icui18n = self.icu;

27+ icudata = self.icu;

28+ })

29+];

30+```

31+

32+### Replace libraries of components

33+

34+If a component is missing a dependency it can be added via modules. For example:

35+

36+``` nix

37+project = pkgs.haskell-nix.project' {

38+ src = self;

39+ compiler-nix-name = "ghc8102";

40+ modules = [{

41+ # Replace `extra-libraries` dependencies

42+ packages.X11.components.library.libs = pkgs.lib.mkForce (with pkgs.xorg;

43+ [ libX11 libXrandr libXext libXScrnSaver libXinerama ]);

44+ }];

45+};

46+```

47+

48+### Mapping in Haskell.nix

49+

50+Alternatively, if the name is commonly used, an alias can be added to

51+the Haskell.nix sources, so that it's solved for all users.

52+

53+* [`lib/pkgconf-nixpkgs-map.nix`](https://github.com/input-output-hk/haskell.nix/blob/master/lib/pkgconf-nixpkgs-map.nix)

54+ — for `pkgconfig-depends`.

55+

56+ Each mapping entry is a list of packages.

57+

58+* [`lib/system-nixpkgs-map.nix`](https://github.com/input-output-hk/haskell.nix/blob/master/lib/system-nixpkgs-map.nix)

59+ — for `build-tool-depends`, `frameworks`, `extra-libraries`, etc.

60+

61+ Each name can be mapped to:

62+ 1. A single package from nixkpgs.

63+ 2. `null` — eliminates the dependency

64+ 3. A list of packages — sometimes needed for dependencies such as `X11`.

65+

66+!!! tip "Open a PR"

67+ Please go ahead and open a [pull request](https://github.com/input-output-hk/haskell.nix/pulls)

68+ to improve the package mappings.

2−

3−[Haskell.nix][] can be use for two different use cases:

4−

5−### Use 1 : to build a specific package from hackage or a [stackage][] lts or nightly set.

6−

7−To build a package, say [lens][], from a stackage snapshot, say [lts-13.28][],

8−you could run

9−```bash

10−nix build '(with import <nixpkgs> (import ./. {}).nixpkgsArgs; haskell-nix.snapshots."lts-13.28").lens.components.library'

11−```

12−which would build the [lens][] library component from the lens package as fixed

13−by the [lts-13.28][] stackage snapshot.

14−

15−To build any package from hackage, say [lens][], in version, say 4.17.1, you

16−could run

17−```bash

18−nix build '(with import <nixpkgs> (import ./. {}).nixpkgsArgs; (haskell-nix.hackage-package { name = "lens"; version = "4.17.1"; })).components.library'

19−```

20−which would build the [lens][] library component from the [lens-4.17.1][] package

21−from hackage. The dependencies would be solved against the most recent

22−[hackage-index-state][] that comes via the [hackage.nix][] pin with your

23−[haskell.nix][] checkout. A specific one can be specified as well:

24−```bash

25−nix build '(with import <nixpkgs> (import ./. {}).nixpkgsArgs; (haskell-nix.hackage-package { name = "lens"; version = "4.17.1"; index-state = "2019-07-14T00:00:00Z"; })).components.library'

27−which would use the hackage index as of `2019-07-14T00:00:00Z` to produce a build plan

28−for the [lens-4.17.1][] package.

30−

31−### Use 2 : to build a stack or cabal project.

32−

33−So you want to use [Haskell.nix][] with your stack or cabal project. The

34−general approach will be to pick the right tool from `nix-tools` and

35−produce a `pkgs.nix` expression. Getting a copy of the `nix-tools`

36−(and potentially the [Haskell.nix][] source), will then equip us to

37−produce derivations that we can `nix build`.

79−`substituter` for `nix` and add the public key found at the url to

80−`trusted-public-keys`.

81−

82−## Using [Haskell.nix][] with your project

83−

84−The easiest way to get a hold of [Haskell.nix][] is with

86−

87−```nix

90−

91−### Using your cabal.project file

92−

93−If your project has a `cabal.project` you can add a `default.nix` like this:

94−

95−```nix

96−{ pkgs ? import <nixpkgs> (import (builtins.fetchTarball https://github.com/input-output-hk/haskell.nix/archive/master.tar.gz) {}).nixpkgsArgs

97−, compiler-nix-name ? "ghc865"

98−}:

99− pkgs.haskell-nix.cabalProject {

100− src = pkgs.haskell-nix.haskellLib.cleanGit { src = ./.; };

101− inherit compiler-nix-name;

102− # pkg-def-extras = [

103− # # Additional packages ontop of all those listed in `cabal.project`

104− # ];

105− # modules = [{

106− # # Specific package overrides would go here for example:

107− # packages.cbors.package.ghcOptions = "-Werror";

108− # packages.cbors.patches = [ ./one.patch ];

109− # packages.cbors.flags.optimize-gmp = false;

110− # # It may be better to set flags in `cabal.project` instead

111− # # (`plan-to-nix` will include them as defaults).

112− # }];

113− }

114−```

115−

116−Note: The `cleanGit` call will exclude any files not in the index file

117−in the local `.git` directory. This is extremely useful as it avoids

118−unwanted builds (for instance when the contents of `dist-newstyle` are

119−modified by cabal). It is important that `src` is the root directory

120−of the repo (so `cleanGit` can find the `.git` directory). If the project

121−is not at the root of the repo, then also pass `subDir` to `cleanGit` with the

122−location of the project relative to `src` as a string ([more information

123−on using cleanGit](clean-git.md)). For example:

124−

125−```

126− src = pkgs.haskell-nix.haskellLib.cleanGit

127− { src = ./.; subDir = "subdir/another-subdir"; };

128−```

129−

130−If you want to use a custom filtering function, don't use the built-in nix `filterSource` function.

131−Due to some technicalities about how filtering and the nix store work, it will cause all components in

132−your project to be rebuilt any time any part of the project source changes. Use `cleanSourceWith` instead:

133−

134−```

135− src = pkgs.haskell-nix.haskellLib.cleanSourceWith

136− { src = ./.; filter = myFilterFunction; };

137−```

138−

139−Note that `cleanSourceWith` will also take the `subDir` argument.

140−

141−You can build a component from your project with `nix-build` (in this

142−case the `hello` executable in a `helloworld` package):

143−

144−```bash

145−nix-build -A helloworld.components.exes.hello

146−```

147−

148−For interactive development you can run:

149−

150−```bash

151−nix-shell -A shellFor

152−```

153−

154−The resulting shell will include all the dependencies of the local packages

155−listed in your `cabal.project` file (but it will not build those local

156−packages).

157−

158−Inside the shell use `cabal new-build` and `cabal new-repl` to work on the

159−cabal project as you normally would. They will use the packages provided

160−by nix whenever possible.

161−

162−It is a good idea to add `write-ghc-environment-files: never` to your

163−`cabal.project` file to prevent unwanted `.ghc.environment.*` files

164−(they will prevent subsequent `nix-shell` invocations from working

165−properly).

166−

167−Adding an `index-state` to your `cabal.project` can pin the plan used so that

168−the same packages will be built each time (until you change the index-state

169−or one of the constraints in your local `.cabal` files).

170−

171−### Using your stack.yaml file

172−

173−If your project has a `stack.yaml` you can add a `default.nix` like this:

174−

175−```nix

176−{ pkgs ? import <nixpkgs> (import (builtins.fetchTarball https://github.com/input-output-hk/haskell.nix/archive/master.tar.gz) {}).nixpkgsArgs

201−### Pinning the [Haskell.nix][] version

202−

203−For simplicity's sake we will use `fetchTarball` for the examples in

204−this documentation. This will always get the latest version, and is

205−similar to an auto-updating Nix channel.

206−

207−However, in your own project, you may wish to pin [Haskell.nix][] (as

208−you would pin Nixpkgs). This will make your builds reproducable, more

209−predictable, and faster (because the fixed version is cached).

210−

211−One way of doing this is to use `nix-prefetch-git` to get a JSON file

212−with a revision and SHA-256 hash of [Haskell.nix][].

213−

214−```

224−

225−(The `tee` command is just to show you the result.)

226−Use the following expression to import that version:

236− };

237−in

238− import nixpkgs (import haskell-nix-src)

239−```

240−

241−There are other possible schemes for pinning. See

242−[`haskell.nix/lib/fetch-external.nix`](https://github.com/input-output-hk/haskell.nix/blob/master/lib/fetch-external.nix),

243−the [niv](https://github.com/nmattia/niv) tool, or the Nix Flakes

244−proposal.

245−

246−### Overriding the Hackage version

247−

248−Sometimes you might want to use a chosen version of Haskell.nix with a

249−recent update of Hackage or Stackage. This can be done with JSON pins:

250−

4−

5−Generating package sets for Cabal projects, is slightly more involved,

7−dependencies of your package(s).

8−

9−## Generating `plan.json`

10−

11−To get a plan, you need Cabal and GHC. See the [How to install a

33− To use a specific compiler version, replace `haskellPackages.ghc`

34− with something like `haskell-nix.compiler.ghc865`. The given compiler

35− must exist in your Nixpkgs version, of course. See also the

3−## What is materialization?

4−

5−Capturing and storing the nix files for a project so that they do

6−not need to be built (or checked). This allows us to cache the input

7−of an IFD (import from derviation).

8−

9−## Why use materialization?

10−

11−Using functions like `cabalProject`, `stackProject` and `hackage-package`

12−results in a lot of dependencies (all the dependencies of nix-tools

13−for instance).

14−

15−* They can be slow to calculate (even if no work needs to be done it

16− is not unusual for it to take 5 seconds per project).

17−

18−* They can be slow to build (or download) on machines that do not

19− yet have them in the nix store.

20−

21−* Hydra does not show progress because it does not provide feedback

22− until it has a list of jobs and the list of jobs cannot depends

23− on the nix being present (although this is often blamed on IFD

24− it would be the same if it wrote out JSON files and read them in)

25−

26−## When is it ok to materialize?

27−

28−* The nix is unlikely to change frequently (and when it does you

29− are happy to manually update it).

30−

31−* You are happy to script something to update the materialized

32− nix files automatically.

33−* You are certain that the IFD you materialize is not `system`-dependent. If it was you'd

34− obtain different nix expressions depending on which `system` the IFD was evaluated.

35−

36−## How can we materialize the nix files?

37−

38−Lets say we want to build `hlint`. We might start with an `hlint`

39−file that looks like this:

40−

41−```nix

46− version = "2.2.11";

61−To materialize the nix files we need to take care to pin down the

62−inputs. For `cabalProject` and `hackage-package` this means

364+ Fast, compact, strict and lazy byte strings with a list interface

365+description:

366+ An efficient compact, immutable byte string type (both strict and lazy)

367+ suitable for binary or 8-bit character data.

368+ The 'ByteString' type represents sequences of bytes or 8-bit characters.

369+ It is suitable for high performance use, both in terms of large data

370+ quantities, or high speed requirements. The 'ByteString' functions follow

371+ the same style as Haskell\'s ordinary lists, so it is easy to convert code

372+ from using 'String' to 'ByteString'.

373+ Two 'ByteString' variants are provided:

374+ * Strict 'ByteString's keep the string as a single large array. This

375+ makes them convenient for passing data between C and Haskell.

376+ * Lazy 'ByteString's use a lazy list of strict chunks which makes it

377+ suitable for I\/O streaming tasks.

378+ The @Char8@ modules provide a character-based view of the same

379+ underlying 'ByteString' types. This makes it convenient to handle mixed

380+ binary and 8-bit character content (which is common in many file formats

381+ and network protocols).

382+ The 'Builder' module provides an efficient way to build up 'ByteString's

383+ in an ad-hoc way by repeated concatenation. This is ideal for fast

384+ serialisation or pretty printing.

385+ There is also a 'ShortByteString' type which has a lower memory overhead

386+ and can can be converted to or from a 'ByteString', but supports very few

387+ other operations. It is suitable for keeping many short strings in memory.

388+ 'ByteString's are not designed for Unicode. For Unicode strings you should

389+ use the 'Text' type from the @text@ package.

390+ These modules are intended to be imported qualified, to avoid name clashes

391+ with "Prelude" functions, e.g.

477+synopsis: Deep evaluation of data structures

478+description:

479+ This package provides methods for fully evaluating data structures

480+ (\"deep evaluation\"). Deep evaluation is often used for adding

481+ strictness to a program, e.g. in order to force pending exceptions,

482+ remove space leaks, or force lazy I/O to happen. It is also useful

483+ in parallel programs, to ensure pending work does not migrate to the

484+ wrong thread.

485+ The primary use of this package is via the 'deepseq' function, a

486+ \"deep\" version of 'seq'. It is implemented on top of an 'NFData'

487+ typeclass (\"Normal Form Data\", data structures with no unevaluated

488+ components) which defines strategies for fully evaluating different

489+ data types. See module documentation in "Control.DeepSeq" for more

574+description:

575+ This package provides functionality for manipulating @FilePath@ values, and is shipped with both <https://www.haskell.org/ghc/ GHC> and the <https://www.haskell.org/platform/ Haskell Platform>. It provides three modules:

576+ * "System.FilePath.Posix" manipulates POSIX\/Linux style @FilePath@ values (with @\/@ as the path separator).

577+ * "System.FilePath.Windows" manipulates Windows style @FilePath@ values (with either @\\@ or @\/@ as the path separator, and deals with drives).

578+ * "System.FilePath" is an alias for the module appropriate to your platform.

579+ All three modules provide the same API, and the same documentation (calling out differences in the different variants).

601+description:

602+ This library is shared between GHC, ghc-pkg, and other boot

603+ libraries.

604+ A note about "GHC.PackageDb": it only deals with the subset of

605+ the package database that the compiler cares about: modules

606+ paths etc and not package metadata like description, authors

607+ etc. It is thus not a library interface to ghc-pkg and is *not*

608+ suitable for modifying GHC package databases.

609+ The package database format and this library are constructed in

610+ such a way that while ghc-pkg depends on Cabal, the GHC library

611+ and program do not have to depend on Cabal.

666+synopsis: In memory storage of deeply evaluated data structure

667+description:

668+ This package provides minimal functionality for working with

669+ "compact regions", which hold a fully evaluated Haskell object graph.

670+ These regions maintain the invariant that no pointers live inside the struct

671+ that point outside it, which ensures efficient garbage collection without

672+ ever reading the structure contents (effectively, it works as a manually

673+ managed "oldest generation" which is never freed until the whole is

674+ released).

675+ Internally, the struct is stored a single contiguous block of memory,

676+ which allows efficient serialization and deserialization of structs

677+ for distributed computing.

967+ stacked on arbitrary monads, and it is also parametric in the

968+ input stream type.

969+ The main entry point is the "Text.Parsec" module which provides

970+ defaults for parsing 'Char'acter data.

971+ The "Text.ParserCombinators.Parsec" module hierarchy contains

1075+description:

1076+ Software Transactional Memory, or STM, is an abstraction for

1077+ concurrent communication. The main benefits of STM are

1078+ /composability/ and /modularity/. That is, using STM you can write

1079+ concurrent abstractions that can be easily composed with any other

1080+ abstraction built using STM, without exposing the details of how

1081+ your abstraction ensures safety. This is typically not the case

1082+ with other forms of concurrent communication, such as locks or

1083+ 'MVar's.

1144+synopsis: An efficient packed Unicode text type.

1145+description:

1146+ An efficient packed, immutable Unicode text type (both strict and

1147+ lazy), with a powerful loop fusion optimization framework.

1148+ The 'Text' type represents Unicode character strings, in a time and

1149+ space-efficient manner. This package provides text processing

1150+ capabilities that are optimized for performance critical use, both

1151+ in terms of large data quantities and high speed.

1152+ The 'Text' type provides character-encoding, type-safe case

1153+ conversion via whole-string case conversion functions (see "Data.Text").

1154+ It also provides a range of functions for converting 'Text' values to

1155+ and from 'ByteStrings', using several standard encodings

1156+ (see "Data.Text.Encoding").

1157+ Efficient locale-sensitive support for text IO is also supported

1158+ (see "Data.Text.IO").

1159+ These modules are intended to be imported qualified, to avoid name

1160+ clashes with Prelude functions, e.g.

1161+ > import qualified Data.Text as T

1162+ To use an extended and very rich family of functions for working

1163+ with Unicode text (including normalization, regular expressions,

1164+ non-standard encodings, text breaking, and locales), see

1165+ the [text-icu package](https://hackage.haskell.org/package/text-icu)

1166+ based on the well-respected and liberally

1167+ licensed [ICU library](http://site.icu-project.org/).

1264+synopsis: Concrete functor and monad transformers

1265+description:

1266+ A portable library of functor and monad transformers, inspired by

1267+ the paper

1268+ * \"Functional Programming with Overloading and Higher-Order

1269+ Polymorphism\", by Mark P Jones,

1270+ in /Advanced School of Functional Programming/, 1995

1271+ (<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>).

1272+ This package contains:

1273+ * the monad transformer class (in "Control.Monad.Trans.Class")

1274+ * concrete functor and monad transformers, each with associated

1275+ operations and functions to lift operations associated with other

1276+ transformers.

1277+ The package can be used on its own in portable Haskell code, in

1278+ which case operations need to be manually lifted through transformer

1279+ stacks (see "Control.Monad.Trans.Class" for some examples).

1280+ Alternatively, it can be used with the non-portable monad classes in

1281+ the @mtl@ or @monads-tf@ packages, which automatically lift operations

1282+ introduced by monad transformers through other transformers.

321+ Efficient, pure binary serialisation using lazy ByteStrings.

322+ Haskell values may be encoded to and from binary formats,

365+ Fast, compact, strict and lazy byte strings with a list interface

366+description:

367+ An efficient compact, immutable byte string type (both strict and lazy)

368+ suitable for binary or 8-bit character data.

369+ The 'ByteString' type represents sequences of bytes or 8-bit characters.

370+ It is suitable for high performance use, both in terms of large data

371+ quantities, or high speed requirements. The 'ByteString' functions follow

372+ the same style as Haskell\'s ordinary lists, so it is easy to convert code

373+ from using 'String' to 'ByteString'.

374+ Two 'ByteString' variants are provided:

375+ * Strict 'ByteString's keep the string as a single large array. This

376+ makes them convenient for passing data between C and Haskell.

377+ * Lazy 'ByteString's use a lazy list of strict chunks which makes it

378+ suitable for I\/O streaming tasks.

379+ The @Char8@ modules provide a character-based view of the same

380+ underlying 'ByteString' types. This makes it convenient to handle mixed

381+ binary and 8-bit character content (which is common in many file formats

382+ and network protocols).

383+ The 'Builder' module provides an efficient way to build up 'ByteString's

384+ in an ad-hoc way by repeated concatenation. This is ideal for fast

385+ serialisation or pretty printing.

386+ There is also a 'ShortByteString' type which has a lower memory overhead

387+ and can can be converted to or from a 'ByteString', but supports very few

388+ other operations. It is suitable for keeping many short strings in memory.

389+ 'ByteString's are not designed for Unicode. For Unicode strings you should

390+ use the 'Text' type from the @text@ package.

391+ These modules are intended to be imported qualified, to avoid name clashes

392+ with "Prelude" functions, e.g.

478+synopsis: Deep evaluation of data structures

479+description:

480+ This package provides methods for fully evaluating data structures

481+ (\"deep evaluation\"). Deep evaluation is often used for adding

482+ strictness to a program, e.g. in order to force pending exceptions,

483+ remove space leaks, or force lazy I/O to happen. It is also useful

484+ in parallel programs, to ensure pending work does not migrate to the

485+ wrong thread.

486+ The primary use of this package is via the 'deepseq' function, a

487+ \"deep\" version of 'seq'. It is implemented on top of an 'NFData'

488+ typeclass (\"Normal Form Data\", data structures with no unevaluated

489+ components) which defines strategies for fully evaluating different

490+ data types. See module documentation in "Control.DeepSeq" for more

967+ and is fast. It is defined as a monad transformer that can be

968+ stacked on arbitrary monads, and it is also parametric in the

969+ input stream type.

970+ The main entry point is the "Text.Parsec" module which provides

971+ defaults for parsing 'Char'acter data.

972+ The "Text.ParserCombinators.Parsec" module hierarchy contains

973+ the legacy @parsec-2@ API and may be removed at some point in

974+ the future.

1145+synopsis: An efficient packed Unicode text type.

1146+description:

1147+ An efficient packed, immutable Unicode text type (both strict and

1148+ lazy), with a powerful loop fusion optimization framework.

1149+ The 'Text' type represents Unicode character strings, in a time and

1150+ space-efficient manner. This package provides text processing

1151+ capabilities that are optimized for performance critical use, both

1152+ in terms of large data quantities and high speed.

1153+ The 'Text' type provides character-encoding, type-safe case

1154+ conversion via whole-string case conversion functions (see "Data.Text").

1155+ It also provides a range of functions for converting 'Text' values to

1156+ and from 'ByteStrings', using several standard encodings

1157+ (see "Data.Text.Encoding").

1158+ Efficient locale-sensitive support for text IO is also supported

1159+ (see "Data.Text.IO").

1160+ These modules are intended to be imported qualified, to avoid name

1161+ clashes with Prelude functions, e.g.

1162+ > import qualified Data.Text as T

1163+ == ICU Support

1164+ To use an extended and very rich family of functions for working

1165+ with Unicode text (including normalization, regular expressions,

1166+ non-standard encodings, text breaking, and locales), see

1167+ the [text-icu package](https://hackage.haskell.org/package/text-icu)

1168+ based on the well-respected and liberally

1169+ licensed [ICU library](http://site.icu-project.org/).

1170+ == Internal Representation: UTF-16 vs. UTF-8

1171+ Currently the @text@ library uses UTF-16 as its internal representation

1172+ which is [neither a fixed-width nor always the most dense representation](http://utf8everywhere.org/)

1173+ for Unicode text. We're currently investigating the feasibility

1174+ of [changing Text's internal representation to UTF-8](https://github.com/text-utf8)

1175+ and if you need such a 'Text' type right now you might be interested in using the spin-off

1176+ packages <https://hackage.haskell.org/package/text-utf8 text-utf8> and

1177+ <https://hackage.haskell.org/package/text-short text-short>.

1276+synopsis: Concrete functor and monad transformers

1277+description:

1278+ A portable library of functor and monad transformers, inspired by

1279+ the paper

1280+ * \"Functional Programming with Overloading and Higher-Order

1281+ Polymorphism\", by Mark P Jones,

1282+ in /Advanced School of Functional Programming/, 1995

1283+ (<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>).

1284+ This package contains:

1285+ * the monad transformer class (in "Control.Monad.Trans.Class")

1286+ * concrete functor and monad transformers, each with associated

1287+ operations and functions to lift operations associated with other

1288+ transformers.

1289+ The package can be used on its own in portable Haskell code, in

1290+ which case operations need to be manually lifted through transformer

1291+ stacks (see "Control.Monad.Trans.Class" for some examples).

1292+ Alternatively, it can be used with the non-portable monad classes in

1293+ the @mtl@ or @monads-tf@ packages, which automatically lift operations

1294+ introduced by monad transformers through other transformers.

364+synopsis:

365+ Fast, compact, strict and lazy byte strings with a list interface

366+description:

367+ An efficient compact, immutable byte string type (both strict and lazy)

368+ suitable for binary or 8-bit character data.

369+ The 'ByteString' type represents sequences of bytes or 8-bit characters.

370+ It is suitable for high performance use, both in terms of large data

371+ quantities, or high speed requirements. The 'ByteString' functions follow

372+ the same style as Haskell\'s ordinary lists, so it is easy to convert code

373+ from using 'String' to 'ByteString'.

374+ Two 'ByteString' variants are provided:

375+ * Strict 'ByteString's keep the string as a single large array. This

376+ makes them convenient for passing data between C and Haskell.

377+ * Lazy 'ByteString's use a lazy list of strict chunks which makes it

378+ suitable for I\/O streaming tasks.

379+ The @Char8@ modules provide a character-based view of the same

380+ underlying 'ByteString' types. This makes it convenient to handle mixed

381+ binary and 8-bit character content (which is common in many file formats

382+ and network protocols).

383+ The 'Builder' module provides an efficient way to build up 'ByteString's

384+ in an ad-hoc way by repeated concatenation. This is ideal for fast

386+ There is also a 'ShortByteString' type which has a lower memory overhead

387+ and can can be converted to or from a 'ByteString', but supports very few

478+synopsis: Deep evaluation of data structures

479+description:

480+ This package provides methods for fully evaluating data structures

481+ (\"deep evaluation\"). Deep evaluation is often used for adding

482+ strictness to a program, e.g. in order to force pending exceptions,

483+ remove space leaks, or force lazy I/O to happen. It is also useful

484+ in parallel programs, to ensure pending work does not migrate to the

485+ wrong thread.

486+ The primary use of this package is via the 'deepseq' function, a

487+ \"deep\" version of 'seq'. It is implemented on top of an 'NFData'

488+ typeclass (\"Normal Form Data\", data structures with no unevaluated

489+ components) which defines strategies for fully evaluating different

490+ data types. See module documentation in "Control.DeepSeq" for more

491+ details.

668+description:

669+ This package provides minimal functionality for working with

671+ These regions maintain the invariant that no pointers live inside the struct

672+ that point outside it, which ensures efficient garbage collection without

673+ ever reading the structure contents (effectively, it works as a manually

674+ managed "oldest generation" which is never freed until the whole is

675+ released).

676+ Internally, the struct is stored a single contiguous block of memory,

677+ which allows efficient serialization and deserialization of structs

678+ for distributed computing.

963+description:

964+ Parsec is designed from scratch as an industrial-strength parser

965+ library. It is simple, safe, well documented (on the package

966+ homepage), has extensive libraries, good error messages,

967+ and is fast. It is defined as a monad transformer that can be

968+ stacked on arbitrary monads, and it is also parametric in the

969+ input stream type.

970+ The main entry point is the "Text.Parsec" module which provides

971+ defaults for parsing 'Char'acter data.

972+ The "Text.ParserCombinators.Parsec" module hierarchy contains

973+ the legacy @parsec-2@ API and may be removed at some point in

974+ the future.

1145+synopsis: An efficient packed Unicode text type.

1146+description:

1147+ An efficient packed, immutable Unicode text type (both strict and

1148+ lazy), with a powerful loop fusion optimization framework.

1149+ The 'Text' type represents Unicode character strings, in a time and

1150+ space-efficient manner. This package provides text processing

1151+ capabilities that are optimized for performance critical use, both

1152+ in terms of large data quantities and high speed.

1153+ The 'Text' type provides character-encoding, type-safe case

1154+ conversion via whole-string case conversion functions (see "Data.Text").

1155+ It also provides a range of functions for converting 'Text' values to

1156+ and from 'ByteStrings', using several standard encodings

1157+ (see "Data.Text.Encoding").

1158+ Efficient locale-sensitive support for text IO is also supported

1159+ (see "Data.Text.IO").

1160+ These modules are intended to be imported qualified, to avoid name

1161+ clashes with Prelude functions, e.g.

1162+ > import qualified Data.Text as T

1163+ == ICU Support

1164+ To use an extended and very rich family of functions for working

1165+ with Unicode text (including normalization, regular expressions,

1166+ non-standard encodings, text breaking, and locales), see

1167+ the [text-icu package](https://hackage.haskell.org/package/text-icu)

1168+ based on the well-respected and liberally

1169+ licensed [ICU library](http://site.icu-project.org/).

1170+ == Internal Representation: UTF-16 vs. UTF-8

1171+ Currently the @text@ library uses UTF-16 as its internal representation

1172+ which is [neither a fixed-width nor always the most dense representation](http://utf8everywhere.org/)

1173+ for Unicode text. We're currently investigating the feasibility

1174+ of [changing Text's internal representation to UTF-8](https://github.com/text-utf8)

1175+ and if you need such a 'Text' type right now you might be interested in using the spin-off

1176+ packages <https://hackage.haskell.org/package/text-utf8 text-utf8> and

1177+ <https://hackage.haskell.org/package/text-short text-short>.

1277+description:

1278+ A portable library of functor and monad transformers, inspired by

1280+ * \"Functional Programming with Overloading and Higher-Order

1282+ in /Advanced School of Functional Programming/, 1995

1283+ (<http://web.cecs.pdx.edu/~mpj/pubs/springschool.html>).

1284+ This package contains:

1285+ * the monad transformer class (in "Control.Monad.Trans.Class")

1286+ * concrete functor and monad transformers, each with associated

1287+ operations and functions to lift operations associated with other

1288+ transformers.

1289+ The package can be used on its own in portable Haskell code, in

1290+ which case operations need to be manually lifted through transformer

1291+ stacks (see "Control.Monad.Trans.Class" for some examples).

1292+ Alternatively, it can be used with the non-portable monad classes in

1293+ the @mtl@ or @monads-tf@ packages, which automatically lift operations

1294+ introduced by monad transformers through other transformers.
