* | Specialize some SYB functionsAlec Theriault2018-11-051-4/+4
| | | | | | | | | | | | | | Perf only change: * Add a 'SPECIALIZE' pragma to help GHC optimize a 'Data a =>' constraint * Manually specialize the needlessly general type of 'specializeTyVarBndrs'
* | Deduplicate some work in 'AttachInstances'Alec Theriault2018-11-051-27/+40
| | | | | | | | | | | | | | | | | | Perf only change: * avoid needlessly union-ing maps * avoid synify-ing instances twice Took this opportunity to add some docs too
* | More explicit foralls (GHC Proposal 0007)Matthew Yacavone2018-10-272-4/+13

* | Set UTF-8 encoding before writing files (#934)Alec Theriault2018-10-165-14/+21
| | | | | | | | | | This should fix #929, as well as guard against future problems of this sort in other places. Basically replaces 'writeFile' (which selects the users default locale) with 'writeUtf8File' (which always uses utf8).

| | * Fix broken instance source links (#869)Alec Theriault2018-07-202-19/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | The problem manifests itself in instances that are defined in modules other than the module where the class is defined. The fix is just to thread through the 'Module' of the instance further along. Since orphan instances appear to already have been working, I didn't do anything there.
| | * Preserve docs on type family instances (#867)Alec Theriault2018-07-202-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Preserve docs on type family instances The only problem was that the instance location was slightly off for type family instances. * Accept output
| | * tyThingToLHsDecl: Preserve type synonyms that contain a forall (#880)Simon Jakobi2018-07-191-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tyThingToLHsDecls: Preserve type synonyms that contain a forall Fixes #879. * Add Note [Invariant: Never expand type synonyms] * Clarify Note [Invariant: Never expand type synonyms]
| | * Avoid line breaks due to line length in Hoogle (#868)Alec Theriault2018-07-061-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Avoid line breaks due to line length in Hoogle Hoogle operates in a line-oriented fashion, so we should avoid ever breaking due to long lines. One way of doing this non-intrusively is to modify the 'DynFlags' that are threaded through the 'Hoogle' module (note this is anyways only passed through for use in the various 'showSDoc' functions). * Amend test case
| | * Export more fixities for Hoogle (#871)Alec Theriault2018-07-051-2/+2
| | | | | | | | | | | | This exports fixities for more things, including class methods and type-level operators.
| | * Renamer: Warn about ambiguous identifiers (#831)Simon Jakobi2018-06-082-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
| | * Improve hyperlinker's 'spanToNewline' (#846)Alec Theriault2018-06-051-7/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'spanToNewline' is used to help break apart the source into lines which can then be partioned into CPP and non-CPP chunks. It is important that 'spanToNewline' not break apart tokens, so it needs to properly handle things like * block comments, possibly nested * string literals, possibly multi-line * CPP macros, possibly multi-line String literals in particular were not being properly handled. The fix is to to fall back in 'Text.Read.lex' to help lex things that are not comments. Fixes #837.
| | * Use `ClassOpSig` instead of `TypeSig` for class methods (#835)Alec Theriault2018-05-231-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | * Fix minimal pragma handling Class declarations contain 'ClassOpSig' not 'Typesig'. This should fix #834. * Accept html-test output

| | * Renamer: Warn about out of scope identifiers. (#819)Simon Jakobi2018-05-081-6/+11
| | |
| | * Remove 'TokenGroup' from Hyperlinker (#818)Alec Theriault2018-05-081-50/+14
| | | | | | | | | | | | | | | Since the hyperlinker backend now relies on the GHC tokenizer, something like 'Bar.Baz.foo' already gets bunched together into one token (as opposed to being spread across 'Bar', '.', 'Baz', '.', and 'foo').
| | * Filter out CRLFs in hyperlinker backend (#813)Alec Theriault2018-05-071-2/+7
| | | | | | | | | This prevents spurious lines from appearing in the final output.
| * | Accumulate explicitly which modules to load for 'attachInstances'Alec Theriault2018-08-212-28/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
