Documentation
lvsSeparator :: Char Source #
The separator of the fields returned by lvs
Utility functions
skipSpaces :: Parser () Source #
Our own space-skipping function, because A.skipSpace also skips newline characters. It skips ZERO or more spaces, so it does not fail if there are no spaces.
A parser recognizing a number of bytes, represented as a number preceeded by a separator and followed by the B character.
stringP :: Parser String Source #
A parser recognizing a string starting with and closed by a separator (both are discarded)
Parser implementation
oneLvParser :: Parser LVInfo Source #
The parser for one line of the diskstatus file.
