Description

A module for working with debian relationships http://www.debian.org/doc/debian-policy/ch-relationships.html

Synopsis

type PkgName = String type AndRelation = [OrRelation] type OrRelation = [Relation] type Relations = AndRelation data Relation = Rel PkgName (Maybe VersionReq) (Maybe ArchitectureReq) data ArchitectureReq = ArchOnly [String] | ArchExcept [String] data VersionReq = SLT DebianVersion | LTE DebianVersion | EEQ DebianVersion | GRE DebianVersion | SGR DebianVersion checkVersionReq :: Maybe VersionReq -> Maybe DebianVersion -> Bool type RelParser a = CharParser () a class ParseRelations a where parseRelations :: a -> Either ParseError Relations pRelations :: RelParser Relations

Types

type PkgName = String

type AndRelation = [OrRelation]

type OrRelation = [Relation]

type Relations = AndRelation

data Relation

Constructors Rel PkgName (Maybe VersionReq) (Maybe ArchitectureReq) Instances Eq Relation Ord Relation Show Relation

data ArchitectureReq

Constructors ArchOnly [String] ArchExcept [String] Instances Eq ArchitectureReq Show ArchitectureReq

data VersionReq

Constructors SLT DebianVersion LTE DebianVersion EEQ DebianVersion GRE DebianVersion SGR DebianVersion Instances Eq VersionReq Ord VersionReq Show VersionReq

Helper Functions

checkVersionReq :: Maybe VersionReq -> Maybe DebianVersion -> Bool

Check if a version number satisfies a version requirement.

Relation Parser

type RelParser a = CharParser () a

class ParseRelations a where

Methods parseRelations :: a -> Either ParseError Relations parseRelations parse a debian relation (i.e. the value of a Depends field). Return a parsec error or a value of type Relations Instances ParseRelations ByteString ParseRelations String

pRelations :: RelParser Relations
