This patch introduces compatibility to base-4.7.0.x. It was tested
on Win 8.1 x86_64, using GHC 7.8.4. It mainly consists of a bunch
of #if !MIN_VERSION(4,8,0) ... #endif additions and a lower bound
on base in the cabal file as well as a general introduction of the
CPP extension via default-extensions.
It also removes a potential error source in tests/Util.hs, since
the backslash in /=\ can lead to strange quirks on certain systems
(backslash and newline only separated by whitespace).
Other, squashed commits:
- Remove 'recent version of base' from Readme
- Change necessary version of GHC
This code benchmarks the "string" primitive and various non-primitive combinators.
The code coverage of these benchmarks is not 100%: new benchmarks should be added
as relevant performance questions are discovered.
Eliminated ‘Text.Megaparsec.Language’ module because at this point it is
clear that already existing definitions are of little use in
Megaparsec. I started writing “default” language definition in
‘Text.Megaparsec.Lexer’.
At this point it should be possible to parse languages where indentation
matters, although we will need to provide more helpers to make it
easier.
The single test covers 100 % of the module's code. However it doesn't
check quality of error messages, so we still have room for improvement.
Manual tests show that error messages are good.
