Debian.Version.Common

Description

A module for parsing, comparing, and (eventually) modifying debian version numbers. http://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Version

Synopsis

data DebianVersion class ParseDebianVersion a where parseDebianVersion :: a -> DebianVersion evr :: DebianVersion -> (Maybe Int, String, Maybe String) epoch version revision buildDebianVersion :: Maybe Int -> String -> Maybe String -> DebianVersion parseDV :: CharParser () (Found Int, NonNumeric, Found NonNumeric)

Exported abstract because the internal representation is likely to change

class ParseDebianVersion a where Source

Methods parseDebianVersion :: a -> DebianVersion Source Instances ParseDebianVersion String ParseDebianVersion ByteString

evr :: DebianVersion -> (Maybe Int, String, Maybe String) Source

Split a DebianVersion into its three components: epoch, version, revision. It is not safe to use the parsed version number for this because you will lose information, such as leading zeros.

epoch

version

revision

buildDebianVersion :: Maybe Int -> String -> Maybe String -> DebianVersion Source

parseDV :: CharParser () (Found Int, NonNumeric, Found NonNumeric) Source

Convert a string to a debian version number. May throw an exception if the string is unparsable -- but I am not sure if that can currently happen. Are there any invalid version strings? Perhaps ones with underscore, or something?
