View Source Minipeg.Parsers (Minipeg v0.1.10)
A collection of parsers
Link to this section Summary
Functions
Parses any character in the specified set, defaulting to all characters
Parser that only succeeds on empty input / end of input
parses an escape char and then any char
This parser always fails
Succeeds if any of the given keywords parse
Parses only an exact occurrance of the literal
string
Parses any character but delimiter, unless it is escpaed by escape_char
or
doubled in case allow_doubles
is true.
Parses any char with the exception of chars in the forbidden
set
parses only if parser parses a string with a prefix that is discarded
A classic string parser which parses input like
This parser always succeeds. N.B. It does not advance the input
parses a string up to the first char in charset
fails iff less then min_count
chars are parsed
