Perf only change:

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

Alec Theriault authored 6 years ago and Alex Biehl committed 6 years ago

* 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

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.

Previously, it was `data` wrapping a `Maybe`, which seems a bit
silly. Obviously, this can be changed back if anyone wants to add
more fields some day.
