39−from each component.

40−3. There is a known issue where if you have three components, such that A depends on B which depends on C

41−then if you load A and C into the session but not B then under certain situations you

42−can get strange errors about a type coming from two different places. See [this repo](https://github.com/fendor/ghcide-bad-interface-files) for

95−

96−`ghcide` has been designed to handle projects with hundreds or thousands of modules. If `ghci` can handle it, then `ghcide` should be able to handle it. The only caveat is that this currently requires GHC >= 8.6, and that the first time a module is loaded in the editor will trigger generation of support files in the background if those do not already exist.

326270## History and relationship to other Haskell IDE's

327271

328−The teams behind this project and the [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme) have agreed to join forces under the [`haskell-language-server` project](https://github.com/haskell/haskell-language-server), see the [original announcement](https://neilmitchell.blogspot.com/2020/01/one-haskell-ide-to-rule-them-all.html). The technical work is ongoing, with the likely model being that this project serves as the core, while plugins and integrations are kept in the [`haskell-language-server` project](https://github.com/haskell/haskell-language-server).

329−

330272The code behind `ghcide` was originally developed by [Digital Asset](https://digitalasset.com/) as part of the [DAML programming language](https://github.com/digital-asset/daml). DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming language has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset. All contributions require a [Contributor License Agreement](https://cla.digitalasset.com/digital-asset/ghcide) that states you license the code under the [Apache License](LICENSE).

Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files.

We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors.

However, since that talk the project has renamed from `hie-core` to `ghcide`, and the repo has moved to [this location](https://github.com/digital-asset/ghcide/).

6−

7− > https://neilmitchell.blogspot.com/2020/05/fixing-space-leaks-in-ghcide.html

8−

9− As an example project, it unpacks Cabal-3.2.0.0 in the local filesystem and

10− loads the module 'Distribution.Simple'. The rationale for this choice is:

11−

12− - It's convenient to download with `cabal unpack Cabal-3.2.0.0`

13− - It has very few dependencies, and all are already needed to build ghcide

14− - Distribution.Simple has 235 transitive module dependencies, so non trivial

15−

16− The experiments are sequences of lsp commands scripted using lsp-test.

17− A more refined approach would be to record and replay real IDE interactions,

18− once the replay functionality is available in lsp-test.

19− A more declarative approach would be to reuse ide-debug-driver:

20−

21− > https://github.com/digital-asset/daml/blob/master/compiler/damlc/ide-debug-driver/README.md

22−

23− The result of an experiment is a total duration in seconds after a preset

24− number of iterations. There is ample room for improvement:

25− - Statistical analysis to detect outliers and auto infer the number of iterations needed

26− - GC stats analysis (currently -S is printed as part of the experiment)

27− - Analyisis of performance over the commit history of the project

28−

29− How to run:

30− 1. `cabal bench`

31− 2. `cabal exec <absolute-path-to-ghcide-bench> -- ghcide-bench-options`

32−

33− Note that the package database influences the response times of certain actions,

34− e.g. code actions, and therefore the two methods above do not necessarily

35− produce the same results.

437−~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

438−Originally, we set the cache directory for the various components once

439−on the first occurrence of the component.

440−This works fine if these components have no references to each other,

441−but you have components that depend on each other, the interface files are

442−updated for each component.

443−After restarting the session and only opening the component that depended

444−on the other, suddenly the interface files of this component are stale.

445−However, from the point of view of `ghcide`, they do not look stale,

446−thus, not regenerated and the IDE shows weird errors such as:

447−```

448−typecheckIface

449−Declaration for Rep_ClientRunFlags

450−Axiom branches Rep_ClientRunFlags:

451− Failed to load interface for ‘Distribution.Simple.Flag’

452− Use -v to see a list of the files searched for.

453−```

454−and

455−```

456−expectJust checkFamInstConsistency

457−CallStack (from HasCallStack):

458− error, called at compiler\\utils\\Maybes.hs:55:27 in ghc:Maybes

459− expectJust, called at compiler\\typecheck\\FamInst.hs:461:30 in ghc:FamInst

460−```

461−

462−To mitigate this, we set the cache directory for each component dependent

463−on the components of the current `HscEnv`, additionally to the component options

464−of the respective components.

465−Assume two components, c1, c2, where c2 depends on c1, and the options of the

466−respective components are co1, co2.

467−If we want to load component c2, followed by c1, we set the cache directory for

468−each component in this way:

469−

470− * Load component c2

471− * (Cache Directory State)

472− - name of c2 + co2

473− * Load component c1

474− * (Cache Directory State)

475− - name of c2 + name of c1 + co2

476− - name of c2 + name of c1 + co1

477−

478−Overall, we created three cache directories. If we opened c1 first, then we

479−create a fourth cache directory.

480−This makes sure that interface files are always correctly updated.

481−

482−Since this causes a lot of recompilation, we only update the cache-directory,

483−if the dependencies of a component have really changed.

484−E.g. when you load two executables, they can not depend on each other. They

485−should be filtered out, such that we dont have to re-compile everything.

63−When updating the code in this file for changes in the GHC AST, you

64−need to pay attention to the following things:

65−

66−1) Symbols (Names/Vars/Modules) in the following categories:

67−

68− a) Symbols that appear in the source file that directly correspond to

69− something the user typed

70− b) Symbols that don't appear in the source, but should be in some sense

71− "visible" to a user, particularly via IDE tooling or the like. This

72− includes things like the names introduced by RecordWildcards (We record

73− all the names introduced by a (..) in HIE files), and will include implicit

74− parameters and evidence variables after one of my pending MRs lands.

75−

76−2) Subtrees that may contain such symbols, or correspond to a SrcSpan in

77− the file. This includes all `Located` things

78−

79−For 1), you need to call `toHie` for one of the following instances

80−

81−instance ToHie (Context (Located Name)) where ...

82−instance ToHie (Context (Located Var)) where ...

83−instance ToHie (IEContext (Located ModuleName)) where ...

84−

85−`Context` is a data type that looks like:

86−

87−data Context a = C ContextInfo a -- Used for names and bindings

88−

89−`ContextInfo` is defined in `HieTypes`, and looks like

90−

91−data ContextInfo

92− = Use -- ^ regular variable

93− | MatchBind

94− | IEThing IEType -- ^ import/export

95− | TyDecl

96− -- | Value binding

97− | ValBind

98− BindType -- ^ whether or not the binding is in an instance

99− Scope -- ^ scope over which the value is bound

100− (Maybe Span) -- ^ span of entire binding

101− ...

102−

103−It is used to annotate symbols in the .hie files with some extra information on

104−the context in which they occur and should be fairly self explanatory. You need

105−to select one that looks appropriate for the symbol usage. In very rare cases,

106−you might need to extend this sum type if none of the cases seem appropriate.

107−

108−So, given a `Located Name` that is just being "used", and not defined at a

109−particular location, you would do the following:

110−

111− toHie $ C Use located_name

112−

113−If you select one that corresponds to a binding site, you will need to

114−provide a `Scope` and a `Span` for your binding. Both of these are basically

115−`SrcSpans`.

116−

117−The `SrcSpan` in the `Scope` is supposed to span over the part of the source

118−where the symbol can be legally allowed to occur. For more details on how to

119−calculate this, see Note [Capturing Scopes and other non local information]

120−in HieAst.

121−

122−The binding `Span` is supposed to be the span of the entire binding for

123−the name.

124−

125−For a function definition `foo`:

126−

127−foo x = x + y

128− where y = x^2

129−

130−The binding `Span` is the span of the entire function definition from `foo x`

131−to `x^2`. For a class definition, this is the span of the entire class, and

132−so on. If this isn't well defined for your bit of syntax (like a variable

133−bound by a lambda), then you can just supply a `Nothing`

134−

135−There is a test that checks that all symbols in the resulting HIE file

136−occur inside their stated `Scope`. This can be turned on by passing the

137−-fvalidate-ide-info flag to ghc along with -fwrite-ide-info to generate the

138−.hie file.

139−

140−You may also want to provide a test in testsuite/test/hiefile that includes

141−a file containing your new construction, and tests that the calculated scope

142−is valid (by using -fvalidate-ide-info)

143−

144−For subtrees in the AST that may contain symbols, the procedure is fairly

145−straightforward. If you are extending the GHC AST, you will need to provide a

146−`ToHie` instance for any new types you may have introduced in the AST.

147−

148−Here are is an extract from the `ToHie` instance for (LHsExpr (GhcPass p)):

149−

150− toHie e@(L mspan oexpr) = concatM $ getTypeNode e : case oexpr of

151− HsVar _ (L _ var) ->

152− [ toHie $ C Use (L mspan var)

153− -- Patch up var location since typechecker removes it

154− ]

155− HsConLikeOut _ con ->

156− [ toHie $ C Use $ L mspan $ conLikeName con

157− ]

158− ...

159− HsApp _ a b ->

160− [ toHie a

161− , toHie b

162− ]

163−

164−If your subtree is `Located` or has a `SrcSpan` available, the output list

165−should contain a HieAst `Node` corresponding to the subtree. You can use

166−either `makeNode` or `getTypeNode` for this purpose, depending on whether it

167−makes sense to assign a `Type` to the subtree. After this, you just need

168−to concatenate the result of calling `toHie` on all subexpressions and

169−appropriately annotated symbols contained in the subtree.

170−

171−The code above from the ToHie instance of `LhsExpr (GhcPass p)` is supposed

172−to work for both the renamed and typechecked source. `getTypeNode` is from

173−the `HasType` class defined in this file, and it has different instances

174−for `GhcTc` and `GhcRn` that allow it to access the type of the expression

175−when given a typechecked AST:

176−

177−class Data a => HasType a where

178− getTypeNode :: a -> HieM [HieAST Type]

179−instance HasType (LHsExpr GhcTc) where

180− getTypeNode e@(L spn e') = ... -- Actually get the type for this expression

181−instance HasType (LHsExpr GhcRn) where

182− getTypeNode (L spn e) = makeNode e spn -- Fallback to a regular `makeNode` without recording the type

183−

184−If your subtree doesn't have a span available, you can omit the `makeNode`

185−call and just recurse directly in to the subexpressions.
