What Parsec used is called “FreeBSD” or “BSD 2 clause”. Addition of the
third clause may require contacting all the authors. To hell with it,
let it be “FreeBSD” (which is anyway better than “BSD-like”), I'm a
hacker, not a lawyer (tm).
This commit clarifies license of the software replacing “BSD3” with more
conventional “BSD 3 clause”.
Another change is addition of the third clause originally missing in
license of Parsec (which is licensed under BSD 2 clause license). The
addition of the third clause in form:
* Neither the names of the copyright holders nor the names of
contributors may be used to endorse or promote products derived from
this software without specific prior written permission.
does not violate original BSD 2 clause license effectively making it BSD
3 clause license (which I find preferable).
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
* Removed ‘optionMaybe’ parser, because ‘optional’ from
‘Control.Applicative’ does the same thing.
* Renamed ‘tokenPrim’ → ‘token’, removed old ‘token’, because
‘tokenPrim’ is more general and ‘token’ is little used.
* Fixed bug with ‘notFollowedBy’ always succeeded with parsers that
don't consume input, see #6.
* Hint system introduced that greatly improved quality of error messages
and made code of ‘Text.Megaparsec.Prim’ a lot clearer.
The improvements affected other modules too:
* Some parsers from ‘Text.Megaparsec.Combinators’ now live in
‘Text.Megaparsec.Prim’.
* Hint system improved error messages, so I needed to rewrite test for
‘Text.Megaparsec.Char.eol’, since it's error messages are very
intelligent now and cannot be emulated by ‘newline’ and ‘crlf’ parsers
used separately.
* Test for Bug9 from old-tests is passed successfully again.
Added new character parsers in ‘Text.Megaparsec.Char’:
* ‘controlChar’
* ‘printChar’
* ‘markChar’
* ‘numberChar’
* ‘punctuationChar’
* ‘symbolChar’
* ‘separatorChar’
* ‘asciiChar’
* ‘latin1Char’
* ‘charCategory’
Renamed some parsers:
‘spaces’ → ‘space’
‘space’ → ‘spaceChar’
‘lower’ → ‘lowerChar’
‘upper’ → ‘upperChar’
‘letter’ → ‘letterChar’
‘alphaNum’ → ‘alphaNumChar’
‘digit’ → ‘digitChar’
‘octDigit’ → ‘octDigitChar’
‘hexDigit’ → ‘hexDigitChar’
Descriptions of old parsers have been updated to accent some
Unicode-specific moments. For example, old description of ‘letter’
stated that it parses letters from “a” to “z” and from “A” to “Z”. This
is wrong, since it used ‘Data.Char.isAlpha’ predicate internally and
thus parsed many more characters.
