Documentation
valueP :: Parser (Doc ann) Source #
Prettyparser for a constructor, which is roughly a word applied to arguments.
>>>
testParse valueP "Just ('c', Left ())"
Just ('c',Left ())
identifierP :: Parser (Doc ann) Source #
An identifier is a liberal version of a "variable or constructor", which roughly means that it's a printable word without parentheses.
>>>
testParse identifierP "_foo'bar"
_foo'bar
numberP :: Parser (Doc ann) Source #
Number in integer or scientific notation.
>>>
testParse numberP "123456"
123456
>>>
testParse numberP "-123.4e56"
-1.234e58
stringLitP :: Parser (Doc ann) Source #
>>>
testParse stringLitP "\"Hello world!\""
"Hello world!"
argP :: Parser (Doc ann) Source #
Anything that could be considered an argument to something else.
>>>
testParse argP "()"
()
>>>
testParse argP "['h', 'e', 'l', 'l', 'o']"
['h','e','l','l','o']
tupleP :: Parser (Doc ann) Source #
Prettyparser for tuples from size 1. Since 1-tuples are just parenthesized expressions to first order approximation, this parser handles those as well.
>>>
testParse tupleP "((), True, 'c')"
((),True,'c')
