Fix hlint Fix hlint * Refactor rawDependencyInformation (#558) * Refactor rawDependencyInformation There are two reasons why this patch is good: 1. We remove the special case of the initial module from the dependency search. It is now treated uniformly like the rest of the modules. 2. rawDependencyInformation can now take a list of files and create dependency information for all of them. This isn't currently used but on my fork we have a rule which gets the dependency information for the whole project in order to create a module graph. It seemed simplest to upstream this part first, which is already a strict improvement to make the overal patch easier to review. * Make indentation not depend on identifier length Co-authored-by: Moritz Kiefer * Remove space leaks in a more robust way (#578) Follow up from #557. We definitely want the progress state to be fully evaluated, so demand that with evaluating functions like evaluate and $!, rather than relying on the compiler to get it right. My guess is the `$!` is unnecessary now we have `evaluate`, but it's also not harmful, so belt and braces approach. * Remove interface loading diagnostics (#579) * Drop interface loading diagnostics * No reason to skip the --test flag anymore * Update to hie-bios 0.5.0 (#552) * Update to hie-bios 0.5.0 * Fix test-cases due to changes in the direct cradle * Update test/exe/Main.hs comment Co-authored-by: Moritz Kiefer Co-authored-by: Moritz Kiefer * Avoid deprecated Shake functions (#584) In 0.18.4 deprioritise was renamed reschedule, so follow the new name. * Make VFSVersion strict (#585) * Remove the ShakeValue on A (#587) * Fix the Hashable instance of Key (#588) * Add Kakoune section to the README (#592) * Add kakoune installation instructions * Add additional files to roots field * Improve the error messages around IdeGlobal's (#598) * #599. register FileExistsMapVar global unconditionally (#600) * Multi Component (#522) * Multi component support In this commit we add support for loading multiple components into one ghcide session. The current behaviour is that each component is loaded lazily into the session. When a file from an unrecognised component is loaded, the cradle is consulted again to get a new set of options for the new component. This will cause all the currently loaded files to be reloaded into a new HscEnv which is shared by all the currently known components. The result of this is that functions such as go-to definition work between components if they have been loaded into the same session but you have to open at least one file from each component before it will work. Only minimal changes are needed to the internals to ghcide to make the file searching logic look in include directories for all currently loaded components. The main changes are in exe/Main.hs which has been heavily rewritten to avoid shake indirections. A global map is created which maps a filepath to the HscEnv which should be used to compile it. When a new component is created this map is completely refreshed so each path maps to a new Which paths belong to a componenent is determined by the targets listed by the cradle. Therefore it is important that each cradle also lists all the targets for the cradle. There are some other choices here as well which are less accurate such as mapping via include directories which is the aproach that I implemented in haskell-ide-engine. The commit has been tested so far with cabal and hadrian. Also deleted the .ghci file which was causing errors during testing and seemed broken anyway.

This is suboptimal in many, many ways: - A hover in module M aborts the typechecking of module M, only to start over! - Read-only commands (hover, code action, completion) need to typecheck all the modules! (or rather, ask Shake to check that the typechecks are current) - There is no way to run non-interfering commands concurrently This is an experiment inspired by the 'ShakeQueue' of @mpickering, and the follow-up discussion in https://github.com/mpickering/ghcide/issues/7 We introduce the concept of the 'ShakeSession' as part of the IDE state. The 'ShakeSession' is initialized by a call to 'shakeRun', and survives until the next call to 'shakeRun'. It is important that the session is restarted as soon as the filesystem changes, to ensure that the database is current. The 'ShakeSession' enables a new command 'shakeRunGently', which appends work to the existing 'ShakeSession'. This command can be called in parallel without any restriction. * Simplify by assuming there is always a ShakeSession * Improved naming and docs * Define runActionSync on top of shakeEnqueue shakeRun is not correct as it never returns anymore * Drive progress reporting from newSession The previous approach reused the shakeProgress thread, which doesn't work anymore as ShakeSession keeps the ShakeDatabase open until the next edit * Deterministic progress messages in tests Dropping the 0.1s sleep to ensure that progress messages during tests are deterministic * Make kick explicit This is required for progress reporting to work, see notes in shakeRun As to whether this is the right thing to do: 1. Less magic, more explicit 2. There's only 2 places where kick is actually used * apply Neil's feedback * avoid a deadlock when the enqueued action throws * Simplify runAction + comments * use a Barrier for clarity A Barrier is a smaller abstraction than an MVar, and the next version of the extra package will come with a suitably small implementation: https://github.com/ndmitchell/extra/commit/98c2a83585d2ca0a9d961dd241c4a967ef87866a * Log timings for code actions, hovers and completions * Rename shakeRun to shakeRestart The action returned by shakeRun now blocks until another call to shakeRun is made, which is a change in behaviour,. but all the current uses of shakeRun ignore this action. Since the new behaviour is not useful, this change simplifies and updates the docs and name accordingly * delete runActionSync as it's just runAction * restart shake session on new component created * requeue pending actions on session restart * hlint * Bumped the delay from 5 to 6 * Add a test for the non-lsp command line * Update exe/Main.hs Co-authored-by: Moritz Kiefer * remove unnecessary FileExists dependency in GetHiFile (#589) * remove unnecessary FileExists dependency It is subsumed by the GetModificationTime dependency.

Thanks @jneira for help discovering them all. There used to be linking errors but I no longer see those after the multi-cradle patch Non Nix ========= The table below shows a couple of combinations of cradles and ghcide versions in a non-Nix environment. All the version mismatches are now handled as follows: - "Cannot satisfy package" - `-package-id` flags referencing package versions not available (generally base) - "bad interface" - tried to load an interface file created by a different version of ghc cradle/ghcide | 8.6 | 8.8 | 8.10 --------------|-----|----|--- Cabal 8.6 | success | cannot satisfy package | cannot satisfy package Cabal 8.8 | cannot satisfy package | success | cannot satisfy package Cabal 8.10 | cannot satisfy package | cannot satisfy package | success Stack 8.6 | success | bad-interface | bad-interfac- Stack 8.8 | bad-interface | success | bad-interface Stack 8.10 | bad-interface | bad-interface | success Nix ========= Because Nix redefines the libdir to point at the run-time ghc installation, it's actually much easier to detect a version mismatch: just compare the compile-time and run-time libdirs * Fix a bug in getHiFileRule (#623) * Fix bug in getHiFileRule * Renamed GetHiFile to GetModIfaceFromDisk for clarity * Add hie.yaml.stack and use none cradle for test data (#626) * Add a none cradle for test data in cabal cradle * Add a stack explicit hie-bios config * Canonicalize the locations in the cradle tests (#628) On macOS, the $TMPDIR folder leads to /var/blahblahblah, but this is canonicalized to /private/var/blahblahblah for reasons beyond my understanding. Either way, there were some test failures because of a mismatch between the two, so canonicalize the Uris inside the locations to fix this * More benchmarks (#625) * Add a benchmark to track startup times * Benchmark automation disable benchmarks easily save GC stats to file cradle, rts, filter and samples options path to ghcide configurable example --help more detailed CSV output hover after edit pause for GC configurable timeout upgrade extra (required to build bench) Include max residency in BenchRun Include all details on output * reduce threadDelay to avoid upsetting lsp-test * Fix startup time measurement * Added new edit experiment * fix doc comment * hlints * Upgrade to lsp-test 0.11.0.2 * Flag failed experiments * Update ghcide.cabal * Performance analysis over time (#629) * benchmark history script * if HEAD no need to rebuild worktree * add bench/README.md * Enable all experiments * Fix dependency tracking for git branches * hlints * Add stack84 extra-deps * Identify failed experiments in graphs * Filter our failed benchmarks from aggregate graphs Otherwise they tend to distort the axis * Improve graphs (more and easier to see colors) * update cradles * customizable output folder * Cache the config for the duration of the script Otherwise the script is vulnerable to config edits * Allow omitting the git: field * Ignore bench-hist intermediate artifacts Handy for including bench-hist results in a branch while avoiding the intermediate artifacts * Write a cabal.project file in the benchmark example (#640) * Write a cabal.project file As suggested in #617. Taken fron #624 * Write a cabal.project.local Otherwise Cabal still errors out * Override default hie dir Otherwise .hi and .hie files end up in different locations, which causes the getDefinition experiment to fail the second time it's run. This is because we assume in ghcide that .hi and .hie files have the same lifetimes, which is not true when the ..hie files are wiped but the .hi files aren't. * Fix crash when writing to a Barrier more than once (#637) * Fix crash when writing to a Barrier more than once * Less confusing now * Report progress when setting up cradle (#644) To do this we pass in the withProgress and withIndefiniteProgress functions from LspFuncs into ShakeExtras * Remove `Strict` from the language extensions used for code actions (#638) Since the code action for language extension suggestions uses substring matching, the presence of the literal name of an extension can trigger a false positive. `Strict` is an identifier that occurs frequently in imports, causing the extension to be suggested rather than the removal of a redundant import. * Cache a ghc session per file of interest (#630) * Cache a GHC session per module We set up a GHC session (load deps, setup finder cache) every time we want to: - typecheck a module - get the span infos This is very expensive, and can be cached. * cache the Ghc session for files of interest only * hlint * fix 8.4 build * Early cut-off for ModSummary rule This allows to bypass work when a module imports & pragmas haven't changed, e.g. GetDependencies, GetDependencyInformation, GetLocatedImports, etc. * remove extraneous reverse Not sure where that came from * review feedback * Add a note on differential benchmarks (#647) * Send WorkDoneProgressEnd only when work is done (#649) * send WorkDoneProgressEnd only when work done * Progress reporting now spans over multiple overlapping kicks * Repurpose benchmark experiments as tests Fixes #650 * use stack to fetch from Hackage * benchmark tests run with the same lsp-test config as other tests * Fix stack cradle in benchmark * Make stack unpack --silent * Fix issues in "code actions after edit" experiment - Repeated breaking edits make ghc run out of suggestions - Diagnostics seem to come and go in-between edits, which leads to a timing issue when asking for code actions. The fix is to wait for diagnostics to be present before asking for code actions * Fix stack.yaml generation in example project * Fix getDefinition in GHC 8.4 Did it break before 0.2.0 or after? * better naming for the progress event TVar * stop progress reporting in shakeShut https://github.com/digital-asset/ghcide/pull/649#discussion_r443408884 * hlint * Finer dependencies for GhcSessionFun (#643) * Cache the results of loadSession until the components change * Track the cradle dependencies * hlint * Add cradle to watched files test * Add comment on sessionVersion field * Retry GHC 8.10 on Windows (#661) It keeps crashing and annoying everyone. The issue is in GHC not in our code and I believe it’s fixed in HEAD already but that doesn’t help us so let’s add some retries for now. * Interface file fixes (#645) * Add test for inconsistent diagnostics * Refactoring ModIfaceFromDisk This started as a pure refactoring to clarify the responsibilities between ModIface and ModIfaceFromDisk, but ended up having some behaviour changes: 1. Regenerate interface when checkOldIface returns something other than UpToDate. This was a bug. 2. Do not generate a diagnostic when regenerating an interface. 2. Previously we conflated stale interface with other errors, and would regenerate in both cases. Now we only regenerate in the first case. Tentative fix for #597 * Split interface tests * Always recompile modules with TH splices Tentative fix for #614 TODO support stability * Fix expectDiagnostics in MacOs * Avoid File does not exist diagnostics for interface files Fixes #642 * Clarify interface tests * hlints * Performance fixes The previous changes were 10X slower, this is 20X faster than those, so 2X faster than upstream, for some benchmarks * formatting * Fix GetModificationTime identity The answer for a GetModification query is independent of the missingFileDiagnostics field (as the diagnostics are not part of the answer) * remove stale comment * Avoid calling ghcSessionDepsDefinition twice * Apply suggestions from code review Co-authored-by: Moritz Kiefer * Code review feedback * Address review feedback https://github.com/digital-asset/ghcide/pull/645/files/49b0d9ac65399edf82a7a9cbbb8d8b5420458d8d#r443383239 * Change recomp to direct cradle Co-authored-by: Zubin Duggal Co-authored-by: Moritz Kiefer * Fix debouncer for 0 delay (#662) * fix debouncer for 0 delay The indirection caused by `async (sleep 0 >> fire)` was causing the progress done messages to be sent before diagnostics, causing the code actions benchmark experiment to fail randomly. * fix exception masking * stack810.yaml: bump (#651) * Delete unused top level binding code action (#657) * Delete unused top level binding code action * Remove redundant brackets according to hlint * Attempt to fix build issue on ghc-8.4 * Fix delete unused binding code action - handle case of top level bindings defined in infix form - when deleting some unused binding expand text deletion range to beginning of next top level binding (if any was found) * Modify delete unused binding code action Sort all inspected bindings by location before processing * Avoid sending top level binding delete action with no TextEdit Happens when there is unused local binding * Make BenchHist non buildable by default and save logs (#666) * [bench-hist] save messages to log file And fix the commitid rule to always rerun the git query * Do not build benchHist by default Hopefully avoiding the additional dependencies for charts * Simplify with FileStdout * Add a flag for bench-hist Could benchHist be a benchmark instead of an executable, removing the need for this flag? Almost. `stack bench` fails because `benchHist` cannot find `ghcide-bench` in the path. It seems like a bad idea to have a benchmark that fails out of the box * Turn benchHist into a benchmark and ghcide-bench into an exe This works out nicely because: 1. benchHist already runs ghcide-bench, 2. benchHist has additional deps, but ghcide-bench does not. (benchmark deps don't get built by default) 3. This is the only way I've found to get ghcide-bench in the PATH for benchHist * Remove redundant dep on applicative-combinators * Bump versions in stack-ghc-lib.yaml * update lower bounds for extra in benchHist executable * Update README guideline on benchmarks * [benchHist] Fix the commitid rule to always rerun the git query * fix caps * Code action: add constraint (#653) * Add missing instance constraint * Add missing instance constraint with existing constraints * Add missing function constraint * Add missing function consraint with existing constraints * Add some comments * Improve type signature regex * Remove redundant bracket * Improve missing constraint searching.

Minor refactor. * Minor refactor * Use stale information if it's available to answer requests quickly (#624) * Use stale information for hover and completions This introduces a new function `useWithStaleFast` which returns with stale information WITHOUT checking freshness like `use` and `useWithStale`. Greatly improve debug logging All actions triggered by shakeRun now also pass an identifier which means that the debug logging shows which actions are starting/finishing We also distinguish between internal and external events. By default external events are ones triggered by runAction and the debug output is displayed to the user in command line and --lsp mode. In order to see internal logging statements, there is a new flag called --verbose which also prints out internal events such as file modification flushes. Cleaner variant using runAfter Step 1: Do not run actions with shakeRun Queue implementation, living, breathing Use a priority queue to schedule shake actions. Most user actions are answered immediately with a cache but also spawn a shake action to check the cached value we consulted was up to date. * Remove DelayedActionExtra * hlint * Fix progress * Always block instead of fail on initial computation * Can block for code lens * Update docs Co-authored-by: Zubin Duggal * Avoid excessive retypechecking of TH codebases (#673) * Hi file stability * fix missing early cutoff in GetModIface * tests for TH reloading * Do not run hlint on test/data * hlints * Fix legacy code path * Update test/exe/Main.hs Co-authored-by: Moritz Kiefer Co-authored-by: Moritz Kiefer * Fix spaninfo Haddocks for local modules (#678) * Fix regression in SpanInfo haddocks for local modules The regression was introduced in #630. I added `GhcSessionDeps` with the idea of reusing the typecheck GHC session for computing the SpanInfo, instead of rebuilding it from scratch. But I forgot to actually reuse it, or maybe the change got lost during the merge. * Add test * Completions need not depend on typecheck of the current file (#670) * Faster completions * optimize withProgressVar We never remove elements from the map so alter is unnecesary * [ghcide-bench] accept ghcide options * Expand completion tests suite * hlints * completions for local foreign decls * Minor improvements for local completions * Restore completion docs in legacy code path * Compatibility with GHC < 8.8 * fix merge issue * address review feedback * Use a global namecache to read `.hie` files (#677) * Use global NameCache for reading HIE files Co-authored-by: Matthew Pickering * ignore hlint * redundant imports * Use hie files as source of truth for name source spans. Since we started reusing `.hi` files, this exposes a bug where definitions aren't available since a bad source span from the `.hi` file gets put into the NameCache. We rectify by ensuring the span in the NameCache always matches the one from the `.hie` file. This has surfaced because an interaction between the commit which uses `.hi` instead of retypechecking and the change to use the shared global NameCache to read `.hie` files. * Add test for missing definitions Co-authored-by: Matthew Pickering * Code action add default type annotation to remove `-Wtype-defaults` warning (#680) * Code action to add default type annotation to satisfy the contraints this is useful when using `traceShow` with with OverloadedStrings and type-defaults warning enabled Handle the following cases: - there is one literal and one contraint to be satisfied - there are mulitple literals and/or multiple constraints Adding type annotations to expressions that trigger type-defaults warning is not part of this changes * Simplify older test * Fix hlint issue * Performance improvements for GetSpanInfo (#681) * Performance improvements getSpanInfo was naively calling getDocumentations multiple times on the same name. Fixed by deduplicating these calls. getDocumentations is implemented on top of InteractiveEval.getDocs, which does a lot of Ghc setup internally and is very inefficient. Fixed by introducing a batch version of getDocs and batching all the calls in getSpanInfo name | success | samples | startup | setup | experiment | maxResidency ------------- | ------- | ------- | ------- | ----- | ---------- | ------------ edit (before) | True | 10 | 6.94s | 0.00s | 6.57s | 177MB edit (after) | True | 10 | 6.44s | 0.00s | 4.38s | 174MB * More performance improvements Played the deduplication trick on lookupName, which is slow for the same reasons as getDocs. Batching made a smaller difference in my measurements, so did not implement it * Fix redundant constraints * Skip the GHCi code paths for documentation We don't use the interactive module, so there's no reason to go through the GHCi code paths. Moreover, they apparently cause problems with ghc-lib. * Skip the GHCi paths for lookupName * Correctly load the module interface * Compatibility with GHC 8.4 and 8.6 * Fix ghc-lib build * Backport HIE files to GHC 8.6 (#689) * Backport HIE files support to 8.6 * Use hie files as source of truth for name source spans. Since we started reusing `.hi` files, this exposes a bug where definitions aren't available since a bad source span from the `.hi` file gets put into the NameCache. We rectify by ensuring the span in the NameCache always matches the one from the `.hie` file. This has surfaced because an interaction between the commit which uses `.hi` instead of retypechecking and the change to use the shared global NameCache to read `.hie` files. * Update to hie-bios 0.6.1 (#693) * Bump lodash from 4.17.15 to 4.17.19 in /extension (#702) Bumps [lodash](https://github.com/lodash/lodash) from 4.17.15 to 4.17.19. - [Release notes](https://github.com/lodash/lodash/releases) - [Commits](https://github.com/lodash/lodash/compare/4.17.15...4.17.19) Signed-off-by: dependabot[bot] Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> * Expect bench experiments to fail with Cabal (#704) * Obtain the GHC libdir at runtime (#696) * Update to hie-bios 0.6.1 * Obtain the GHC libdir at runtime using hie-bios This replaces hardcoding the GHC libdir path with ghc-paths and instead gets it at runtime through the hie-bios cradle. This means that the ghcide binary should be a bit more distributable now, since it won't rely on paths baked at compile time that are local to the machine it was compiled on. And we also no longer need the ghcLibCheck since we are comparing the coompiled and runtime versions with the installationCheck (ghcVersionChecker) Co-authored-by: Fendor * Relax upper bounds for GHC 8.10.1 (#705) * Relax upper bounds for GHC 8.10.1 * Update cabal.project Co-authored-by: Moritz Kiefer * Allow GHC plugins to be called with an updated StringBuffer (#698) * Ignore tags file * Pass an updated StringBuffer in ModSummary construction The `getModSummaryFromBuffer` function constructs a `ModSummary` that will be included in the `ParsedModule` data structure ghcide will later on typecheck, calling any registred plugin in the process. There was a problem, though: such `ModSummary` didn't include the updated `StringBuffer` representing the in-memory content of a file being edited (inclusive of all its unsaved changes). This was causing plugins to not react in real time and emitting diagnostics only upon save. This commit fixes it. * Populate ms_hs_date in GetModSummary rule (#694) * Populate ms_hs_date in GetModSummary rule * More faithful ModSummary timestamps * More ModSummary timestamps * Address duplication * Remove a displaced comment * Fix Binary instance of Q to handle empty file paths (#707) * Code action: remove redundant constraints for type signature (#692) * Code action: remove redundant constraints for type signature * Handle peculiar formatting Make the content parsing safe for type signature formatted with an arbitrary and unexpected number of spaces and/or line feeds. * Move session loading logic into ghcide library (#697) * Split out the session loading logic into a sublibrary This way haskell-language-server can also reuse this logic. Note that this sublibrary is public so it requires cabal-version: 3.0 Part of the work towards #478 * Move Development.IDE.Session into ghcide itself Sublibraries do not seem to play well. Hide this behind the ghc-lib flag so that the Haskell specific hie-bios stuff can be disabled Note that we need to put the template-haskell part of this module into a separate module because of an access exception when compiling with Stack, GHC 8.10.1 and Windows. * Expose GHC.Compat module (#709) For use in haskell-language-server plugins * Add links to haddock and hscolour pages in documentation (#699) Currently this only searches local documentation (generated with `cabal haddock --haddock-hyperlink-source` or equivalent) but could be extended to support searching via Hoogle in the future. And it works for any of the core libraries since they come installed with documentation. Will show up in hover and (non-local) completions. Also fixes extra markdown horizontal rules being inserted with no content in between them. * Codeaction for exporting unused top-level bindings (#711) * Add PatSynBind to GHC.Compat * Tests for "export unused top level binding" codeaction * Add "export unused top-level binding" codeaction * exportUnusedTests refactored * Fix export unused codeaction * NFC: remove unused import * hlint * add exports to the end of list instead * handle the case where last export end with comma * Add session-loader to hie.yaml (#714) * CI: remove (internal) DA Slack notifications (#750) With the repo now officially transferred from Digital Asset's control to the open-source Haskell organization, there is no good reason for master builds to ping DA anymore. This (the corresponding Slack token "secret") is also the only piece of non-open-source configuration in the existing build process, so it needs to be removed before the CI can be transferred. * Prepare release of ghcide 0.3.0 (#753) * Prepare release of ghcide 0.3.0 * Add ghcide contributors to copyright * Typecheck entire project on Initial Load and typecheck reverse dependencies of a file on saving (#688) * Add new command to GetModuleGraph for a session and propate changes to modules Only propagate changes to parent modules when saving Typecheck files when they are opened, don't TC FOI Add known files rule Don't save ifaces for files with defered errors Co-authored-by: Zubin Duggal * Add configuration for parent typechecking * hlint ignore * Use targets to filter located imports (#10) * Use targets to filter located imports * Remove import paths from the GHC session Otherwise GHC will prioritize source files found in the import path * Update session-loader/Development/IDE/Session.hs Co-authored-by: Pepe Iborra * Add session-loader to hie.yaml (#714) * move known files rule to RuleTypes * Disable checkParents on open and close document (#12) * Really disable expensive checkParents * Add an option to check parents on close Co-authored-by: Matthew Pickering Co-authored-by: Pepe Iborra Co-authored-by: Luke Lau * output which cradle files were found (#716) * Use argsVerbose to determine log level in test mode (#717) * Fix `.hie` file location for `.hs-boot` files (#690) * Find source for boot files * fix modlocs for boot files * Add test * Fix build on 8.6 * Generate doc file URL via LSP (to fix it for Windows) (#721) * use three slashes in doc file URLs to fix it for Windows * generate normalized doc file URL using LSP * Fix issue #710: fix suggest delete binding (#728) * [CodeAction] reimplement suggestDeleteBinding * [CodeAction] handle whole line removal for suggestDeleteUnusedBinding * [CodeAction] add test for bug #710 * [CodeAction] add more tests for suggesting unused binding * fix hlint warnings * fix hlint warnings * remove unused imports * fix compilation problem for 8.4 * remove redundant pattern matching * reconcile the disagreement of a pattern matching is redundant * Ignore -Werror (#738) * Ignore -Werror Fixes #735 * Compat with GHC < 8.8 * Bump hie-bios bounds (#744) * module Development.IDE (#724) A single module to reexport all the commonly used names to simplify the use of ghcide as a library * Include module path in progress message (#746) * Suggest open imports (#740) Also fixes two bugs with qualified imports Fixes #480 * Show documentation on hover for symbols defined in the same module (#691) * Show documentation on hover for symbols defined in the same module When parsing a module, if parsing haddocks succeeds, then use them Previously, even though we were parsing modules twice, with and without haddocks, we were just returning the result of parsing without haddocks. The reason for this was that Opt_KeepRawTokenStream and Opt_Haddock do not interact nicely. We decided that for now it was better to fix an actual issue and then solve the problem when hlint requires a module with Opt_KeepRawTokenStream. * Add option to decide which ParsedModule to return * Use InitializeParams.rootUri for initial session setup (#713) * add rootUri tests * use rootUri in session loader * Don't report nonsense file names (#718) * Don't report nonsense file names * add and fix -Wincomplete-uni-patterns * Add a test case involving -fno-warn-missing-signatures (#720) * Only enable non-fatal warnings * Revert the change since it has been taken care of in #738 * Dynamically load libm on Linux for each new session (#723) This fixes the issue on Linux where the binary was statically linked and Template Haskell (or the eval plugin on haskell-language-server) tried to evaluate some code. It would previously fail to load ghc-prim because it couldn't lookup symbols from libm which are usually dynamically linked in. * Suggestions for missing imports from local modules (#739) * Suggestions for missing imports from local modules * Avoid unnecessary work on InitialLoad when checkProject is off * Expose `getCompletionsLSP` to allow completions in hls (#756) Co-authored-by: Koray Al * Remove duplicate line from changelog (#754) * Remove duplicate line from changelog * Bump release date * Fix haddock to markdown conversion (#757) * Minimal nix-shell script (#749) * Add ghc-check >=0.5.0.1 version bound (#761) * Increase timeout of azure windows job (#762) * Handle multiple user actions concurrently (#727) * tighten some return types * Extract ShakeQueue from shakeSession Instead of creating a new TQueue on every restart, we reuse the same TQueue over and over. The trickiest bit is to ensure that enqueued actions are always retried when a Shake session is cancelled. The ActionQueue datatype is intended to manage this complexity. * Handle multiple user actions concurrently * Fixes for .ghci Unfortunately these are dependent on the ghc version * redundant parens * Formatting * Attempt fix for completion tests These tests are failing because ghcide is sending diagnostics interleaved with completions now (which is good) and the tests cannot handle it * remove debugging printout * simplify * Fix a test * Fix flaky tests * Don't typecheck parents when there are no known files (#758) * Refinement holes (#748) * Refinement holes * Set more GHC options and use indentation for parsing * Add an option to customize the typed holes settings Refinement hole fits are very cool, but currently too slow to enable at deeper levels.

Import paths are relative to cradle I noticed ghcide HEAD was broken on the ghcide submodule of the hls repo. * remove unused * Fix comment placement * Special case the implicit cradle The implicit cradle comes without import paths, so we need to preserve the old logic that synthetised them from the current module * Hlint * Fix timing issue: update known files before restarting the session Also, DO NOT filter out missing targets * Use --verbose when running tests * Log test outputs on 3rd attempt * Fall back to filtering known files * hlint * Upgrade KnownFiles to KnownTargets * Use

Instead we send precisely one. This has some consequences for the behaviour of the fast file existence lookup, which I've noted in the code, alongside a description of how it works (I spent a while figuring it out, I thought I might as well write it down).

This is particularly interesting for people building command line tools using `ghcide`, like the our DAML compiler at Digital Asset. tools with command line drivers, like us at Digital Asset. I would argue that VS Code has the ultimate authority on this since we can't change what it displays without also moving the squiggly lines. This PR fixes the discrepance by simply adding one to the column number in the prtty printer, like we do for the line number. * Add code action for remove all redundant imports (#867) * Add code action for remove all redundant imports * Call suggestRemoveRedundantImport only once * Adjust tests for code action removing all redundant imports * Update src/Development/IDE/Plugin/CodeAction.hs Co-authored-by: Pepe Iborra * Refactor removeAll * Update the test of remove all redundant imports Co-authored-by: Pepe Iborra * Switch back to bytecode (#873) * Switch back to bytecode * return a HomeModInfo even if we can't generate a linkable * set target to HscNothing * add rule for GetModIfaceWithoutLinkable * use IdeGlobal for compiled linkables * Fix the guard target (#876) * Add a test to check diagnistic ranges are printed 1-based (#878) Recently, we fixed a bug in `prettyRange` where lines where rendered 1-based but columns 0-based. Let's make sure we don't get into such weird situations again by adding a test. * Move HIE files stuff to a new hie-compat package (#877) * Move HIE files stuff to a new hie-compat package * add ghc-lib flag for hie-compat * ghc-lib :( * ghc-lib :((( * ghc-lib :(((( * ghc-lib :((((( * Fix cabal check for hie-compat (#879) * Fix cabal check for hie-compat * ghc-lib :(((((( * simplify things unnecessarily running in GhcM (#875) * simplify things unnecessarily running in GhcM * untick catchSrcErrors * set useUnicode * Clarify and downgrade implicit-hie message (#883) * Don't need to invoke full typechecking logic for completions (#882) * Don't need to invoke full typechecking logic for completions tcRnImportDecls is sufficient * return imports along with ModSummary * Use implicit-hie-0.1.2.0 (#880) * Simplify and deduplicate ModSummary logic (#884) * Simplify and dedup parsing logic * delete removePackageImports * add dependencies on included files * hlint * Expose Development.IDE.Core.Preprocessor (#887) * Disable CI benchmark suite (#893) * Test the stack version in the benchmark CI script * [bench script] specify cwd in findGhc * Disable CI bench script * Expose Development.IDE.GHC.Orphans (#894) * Compatibility with fbghc (#892) * Compatibility with fbghc Rather than forking ghcide, we use conditional compilation to build with https://github.com/facebook/fbghc hopefully only until certain changes have been upstreamed. * Reexport DynFlags from Compat.GHC * Add a link to the fbghc repo * GitHub actions (#895) * Add Github action for benchmarks * Change action name to benchmark * Fix - remove empty env section * Rename step * Add steps to print and upload results * Shrink the matrix of versions for benchmarking * Enable benchmarks * rename job * Fix fetch * bump actions/setup-haskell * disable windows - bench script requires Cairo * Delete Azure bench script * add comment on git fetch call * clean up cache key * Update archive step * Prepare for 0.5.0 release (#896) The changelog is a trimmed down summary of the git log.
