| * Load plugins when compiling each module (#983)Alec Theriault2018-12-201-1/+8
| | | | | | | | | | | | | | | | | | | | * WIP: Load (typechecker) plugins from language pragmas * Revert "Load plugins when starting a GHC session (#905)" This reverts commit 72d82e52f2a6225686d9668790ac33c1d1743193. * Simplify plugin initialization code
* | Use `.hie` files for the Hyperlinker backend (#977)Alec Theriault2019-01-311-45/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | # Summary This is a large architectural change to the Hyperlinker. * extract link (and now also type) information from `.hie` instead of doing ad-hoc SYB traversals of the `RenamedSource`. Also adds a superb type-on-hover feature (#715). * re-engineer the lexer to avoid needless string conversions. By going directly through GHC's `P` monad and taking bytestring slices, we avoid a ton of allocation and have better handling of position pragmas and CPP. In terms of performance, the Haddock side of things has gotten _much_ more efficient. Unfortunately, much of this is cancelled out by the increased GHC workload for generating `.hie` files. For the full set of boot libs (including `ghc`-the-library) * the sum of total time went down by 9-10% overall * the sum of total allocations went down by 6-7% # Motivation Haddock is moving towards working entirely over `.hi` and `.hie` files. This change means we no longer need the `RenamedSource` from `TypecheckedModule` (something which is _not_ in `.hi` files). # Details Along the way a bunch of things were fixed: * Cross package (and other) links are now more reliable (#496) * The lexer tries to recover from errors on every line (instead of at CPP boundaries) * `LINE`/`COLUMN` pragmas are taken into account * filter out zero length tokens before rendering * avoid recomputing the `ModuleName`-based `SrcMap` * remove the last use of `Documentation.Haddock.Utf8` (see #998) * restructure temporary folder logic for `.hi`/`.hie` model

| * Renamer: Warn about ambiguous identifiers (#831)Simon Jakobi2018-06-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Renamer: Warn about ambiguous identifiers Example: Warning: 'elem' is ambiguous. It is defined * in ‘Data.Foldable’ * at /home/simon/tmp/hdk/src/Lib.hs:7:1 You may be able to disambiguate the identifier by qualifying it or by hiding some imports. Defaulting to 'elem' defined at /home/simon/tmp/hdk/src/Lib.hs:7:1 Fixes #830. * Deduplicate warnings Fixes #832.
* | Accumulate explicitly which modules to load for 'attachInstances'Alec Theriault2018-08-211-24/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The old approach to fixing #469, while correct, consumes a lot of memory. We ended up with a HUGE 'GblRdrEnv' in 'ic_rn_gbl_env'. However, 'getNameToInstancesIndex' takes that environment and compresses it down to a much smaller 'ModuleSet'. Now, we compute that 'ModuleSet' explicitly as we process modules. That way we can just tell 'getNameToInstancesIndex' what modules to load (instead of it trying to compute that information from the interactive context). (cherry picked from commit 5c7c596c51d69b92164e9ba920157b36ce2b2ec1)

For example, this warning contains it: ``` Language\Haskell\HsColour\ANSI.hs:62:10: warning: [-Wmissing-methods] • No explicit implementation for ‘toEnum’ • In the instance declaration for ‘Enum Highlight’ ``` `(2)` is caused when the input file of `readFile` contains some Unicode characters. In the case above, '⇒' is the cause. Environment ---- OS: Windows 10 haddock: 2.17.3 GHC: 8.0.1 Solution ==== Add `hSetEncoding handle utf8` to avoid the errors. Note ==== - I found the detailed causes by these changes for debugging: - https://github.com/haskell/haddock/commit/8f29edb6b02691c1cf4c479f6c6f3f922b35a55b - https://github.com/haskell/haddock/commit/1dd23bf2065a1e1f2c14d0f4abd847c906b4ecb4 - These errors happen even after executing `chcp 65001` on the console. According to the debug code, `hGetEncoding stderr` returns `CP932` regardless of the console encoding. * Avoid 'internal error: <stderr>: hPutChar: invalid argument (invalid character)' non UTF-8 Windows Better solution for 59411754a6db41d17820733c076e6a72bcdbd82b's (1)
