This parser can be told to parse from ‘m’ to ‘n’ occurrences of some
thing. Old parser ‘count’ is now named ‘count’' and defined in terms of
that more powerful one.
This commit also reorders functions in module
‘Text.Megaparsec.Combinator’ and everywhere where the functions are
listed. The same order is used everywhere.
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.
New tests shows that I had wrong assumption about workings of this
particular function. This is not a problem, though, complete test-suite
will eliminate this sort of nuisance soon.
