Data.Gettext.Parsers

This module contains parsers for:

• Catalog headers (Name: Value lines, that are specified as translation for empty string in po file);
• Plural form selection expressions (specified in Plural-Forms header).

These parsers are already used by main module; but they can be useful for other libraries working with gettext's files.

Types

type Header = (Text, Text)

Catalog header, i.e. one Name: Value line in po file

type Headers = [Header]

List of catalog headers

Parsing functions

parseHeaders :: Text -> Either String Headers

Parse catalog headers. NB: for now this function does not use Parsec.

parsePlural :: Headers -> Either String (Int, Expr)

Parse plural form selection definition. Return value is (number of possible plural forms; selection expression).

Parsec parsers

pHeaders :: Parser Headers

Parsec parser for catalog headers

pExpr :: Parser Expr

Parse plural form selection expression. Note: this parses only part which goes after plural=.

pPlural :: Parser (Int, Expr)

Parse plural form selection definition. This parses the whole value of Plural-Forms header, starting from nplurals=.
