Fix crash in `haddock-library` on unicode space

2020-03-28T00:34:33+00:00

Our quickcheck tests for `haddock-library` stumbled across an edge case input that was causing Haddock to crash: it was a unicode space character. The root cause of the crash is that we were implicitly assuming that if a space character was not " \t\f\v\r", it would have to be "\n". We fix this by instead defining horizontal space as: any space character that is not '\n'. Fixes #1142

Fix build-failure regression for base < 4.7

2019-12-08T11:09:54+00:00

The `$>` operator definition is available only since base-4.7 which unfortunately wasn't caught before release to Hackage (but has been fixed up by a metadata-revision) This commit introduces a `CompatPrelude` module which allows to reduce the amount of CPP by ousting it to a central location, i.e. the new `CompatPrelude` module. This pattern also tends to reduce the tricks needed to silence unused import warnings. Addresses #1119

Release haddock-2.23, haddock-library-1.8.0

2019-05-26T21:57:52+00:00

Tentatively adjust bounds and changelogs for the release to be bundled with GHC 8.8.1.

Better identifier parsing

2019-02-25T08:42:46+00:00

* '(<|>)' and '`elem`' now get parsed and rendered properly as links * 'DbModule'/'DbUnitId' now properly get split apart into two links * tuple names now get parsed properly * some more small niceties... The identifier parsing code is more precise and more efficient (although to be fair: it is also longer and in its own module). On the rendering side, we need to pipe through information about backticks/parens/neither all the way through from renaming to the backends. In terms of impact: a total of 35 modules in the entirety of the bootlib + ghc lib docs change. The only "regression" is things like '\0'. These should be changed to @\\0@ (the path by which this previously worked seems accidental).

Faster 'Text' driven parser combinators

2018-11-05T23:54:22+00:00

Perf only change: * use 'getParserState'/'setParserState' to make 'Text'-optimized parser combinators * minimize uses of 'Data.Text.{pack,unpack,cons,snoc}'

Build on 7.4 and 7.8

Replace 'attoparsec' with 'parsec' (#799)

2018-04-25T18:24:07+00:00

* Remove attoparsec with parsec and start fixing failed parses * Make tests pass * Fix encoding issues The Haddock parser no longer needs to worry about bytestrings. All the internal parsing work in haddock-library happens over 'Text'. * Remove attoparsec vendor * Fix stuff broken in 'attoparsec' -> 'parsec' * hyperlinks * codeblocks * examples Pretty much all issues are due to attoparsec's backtracking failure behaviour vs. parsec's non-backtracking failure behaviour. * Fix small TODOs * Missing quote + Haddocks * Better handle spaces before/after paragraphs * Address review comments

Remove bang pattern

Support unicode operators, proper modules

2018-03-02T14:48:36+00:00

Unicode operators are a pretty big thing in Haskell, so supporting linking them seems like it outweighs the cost of the extra machinery to force Attoparsec to look for unicode. Fixes #458.

Consequently use inClass and notInClass in haddock-library (#617)

2017-05-13T10:48:10+00:00

These allow attoparsec to do some clever lookup optimization
