* Add standard Unicode case predicates isUpperCase and isLowerCase.Pierre Le Marre2022-10-141-2/+53
| | | | | | | | These predicates use the standard Unicode case properties and are more intuitive than isUpper and isLower. Approved by CLC in https://github.com/haskell/core-libraries-committee/issues/90#issuecomment-1276649403. Fixes #14589
* Pure Haskell implementation of GHC.UnicodePierre Le Marre2022-06-011-63/+58
| | | | | | | | | | | | | | | | | | | | | | | | Switch to a pure Haskell implementation of base:GHC.Unicode, based on the implementation of the package unicode-data (https://github.com/composewell/unicode-data/). Approved by CLC as per https://github.com/haskell/core-libraries-committee/issues/59#issuecomment-1132106691. - Remove current Unicode cbits. - Add generator for Unicode property files from Unicode Character Database. - Generate internal modules. - Update GHC.Unicode. - Add unicode003 test for general categories and case mappings. - Add Python scripts to check 'base' Unicode tests outputs and characters properties. Fixes #21375 ------------------------- Metric Decrease: T16875 Metric Increase: T4029 T18304 haddock.base -------------------------
* Correct doctestsOleg Grenrus2021-01-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's simpler to assume that base is NoImplicitPrelude, otherwise running doctest on `GHC.*` modules would be tricky. OTOH, most `GHC.List` (where the most name clashes are) examples could be changed to use `import qualified Data.List as L`. (GHC.List examples won't show for Foldable methods...). With these changes majority of doctest examples are GHCi-"faithful", my WIP GHC-independent doctest runner reports nice summary: Examples: 582; Tried: 546; Skipped: 34; Success: 515; Errors: 33; Property Failures 2 Most error cases are *Hangs forever*. I have yet to figure out how to demonstrate that in GHCi. Some of divergences are actually stack overflows, i.e. caught by runtime. Few errorful cases are examples of infinite output, e.g. >>> cycle [42] [42,42,42,42,42,42,42,42,42,42... while correct, they confuse doctest. Another erroneous cases are where expected output has line comment, like >>> fmap show (Just 1) -- (a -> b) -> f a -> f b Just "1" -- (Int -> String) -> Maybe Int -> Maybe String I think I just have to teach doctest to strip comments from expected output. This is a first patch in a series. There is plenty of stuff already.

* base: Expose GHC.Unicode.unicodeVersionBen Gamari2020-02-121-0/+7
| | | | | | | | | | | | | This exposes a Data.Version.Version representing the version of the Unicode database used by `base`. This should clear up some confusion I have seen in tickets regarding with which Unicode versions a given GHC can be expected to work. While in town I also regenerated (but did not update) the Unicode database with database 12.0.0. Strangely, the file cited in the README no longer existed. Consequently, I used https://www.unicode.org/Public/12.0.0/ucd/UnicodeData.txt and was slightly surprised to find that there were a few changes.

* Fix ambiguous/out-of-scope Haddock identifiersAlec Theriault2018-08-211-1/+1
| | | | | | | | | | | | | | | | | This drastically cuts down on the number of Haddock warnings when making docs for `base`. Plus this means more actual links end up in the docs! Also fixed other small mostly markup issues in the documentation along the way. This is a docs-only change.

* Fixes isAlphaNum re. isAlpha/isNumber and doc fix (trac issue #10412)ARJANEN Loïc Jean David2018-04-191-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Corrects the inconsistency between Data.Char.isAlphaNum, Data.Char.isAlpha and Data.Char.isNumber. Indeed, isAlphaNum was returning True not only when isAlpha or isNumber returned True but also when isMark did. The selectors for the Mn, Mc and Me general categories where removed from the macro generating u_iswalnum in ubconfc. Also, Data.Char.isAlphaNum's documentation was changed to state that isAlphaNum returns true not only for Unicode number digits but for Unicode numbers in general in Unicode.hs.

* Refactor to avoid need for `Unicode.hs-boot`Herbert Valerio Riedel2014-10-111-25/+23
| | | | | | | | | | | This avoids the import-cycle caused by the import of `Foreign.C.Types` by using `Int` instead of `CInt` for the Unicode classification functions. This refactoring also allows to remove a couple of `fromIntegral`s. Reviewed By: rwbarton, ekmett Differential Revision: https://phabricator.haskell.org/D328
* Drop redundant `{-# LANGUAGE #-}` pragmasHerbert Valerio Riedel2013-09-281-1/+1
| | | | | | | | | | | | | This removes language pragmas from Haskell modules which are implicitly active with `default-language: Haskell2010`. Specifically, the following language extension pragmas are removed by this commit: - PatternGuards - ForeignFunctionInterface - EmptyDataDecls - NoBangPatterns Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
* Remove obsolete pre-Haddock-2 `#hide` pragmasHerbert Valerio Riedel2013-09-231-1/+0
| | | | | | | | | | | | The now obsolete (and redundant) `#hide` pragmas have been superseded by `{-# OPTIONS_HADDOCK hide #-}` pragmas which are used by most of the affected modules anyway. This commit also adds proper `{-# OPTIONS_HADDOCK hide #-}` pragmas to `GHC.Desugar` and `GHC.IO.Encoding.Iconv` which had only the ineffective `#hide` annotation.

| | | | | | | | | | Add explicit {-# LANGUAGE xxx #-} pragmas to each module, that say what extensions that module uses. This makes it clearer where different extensions are used in the (large, variagated) base package. Now base.cabal doesn't need any extensions field Thanks to Bas van Dijk for doing all the work.
