Introduction to Po4a
The goal of po4a (PO for anything) project is to ease translations (and more interestingly, the maintenance of translations) using gettext tools on areas where they were not expected like documentation.
In po4a each documentation format is handled by a module. Presently, we have a module for the following formats:
- asciidoc: AsciiDoc format.
- dia: uncompressed Dia diagrams.
- docbook: DocBook XML.
- guide: Gentoo Linux's XML documentation format.
- ini: INI format.
- kernelhelp: Help messages of each kernel compilation option.
- latex: LaTeX format.
- man: Good old manual page format.
- pod: Perl Online Documentation format.
- sgml: either DebianDoc or DocBook DTD.
- texinfo: The info page format.
- tex: generic TeX documents (see also latex).
- text: simple text document.
- wml: WML documents.
- xhtml: XHTML documents.
- xml: generic XML documents (see also docbook).
- yaml: YAML documents.
To install this module type the following:
perl Build.PL ./Build ./Build install
po4a is particularly welcoming contributions from the community. If you are new to Open Source, we'd love to mentor you for your first contributions. Please see the CONTRIBUTING file to see how you could help.
Use without installation
If you want to use a version without installing it (e.g. directly from the git tree), use the PERLLIB environment variable as such:
PERLLIB=~/git-checkouts/po4a/lib ~/git-checkouts/po4a/po4a-gettextize [usual args]
This module being itself internationalized, it needs the Locale::gettext library to translate its own messages. If it is not present, then po4a's messages won't be translated, but po4a will remain fully functional.
This module is used to format po4a's warnings and error messages. It permits to wrap long error messages without splitting words. If it is not present, the formatting of messages will be different, but po4a will remain fully functional.
This module is used to retrieve the terminal's line width. It is not used if Text::WrapI18N is not available. If it is not present, the line width can be specified with the COLUMN environment variable.
SGML module specific dependencies
This is a set of Perl5 routines for processing the output from the onsgmls SGML parser.
opensp (1.5.2) OpenJade group's SGML parsing tools
This is the SGML parser we use.
docbook: used in the tests. Without this package, the test fails with:
onsgmls:<OSFD>0:1:59:W: cannot generate system identifier for public text "-//OASIS//DTD DocBook V4.1//EN" onsgmls:<OSFD>0:6:0:E: reference to entity "REFENTRY" for which no system identifier could be generated onsgmls:<OSFD>0:1:0: entity was defined here onsgmls:<OSFD>0:6:0:E: DTD did not contain element declaration for document type name po4a::sgml: Error while running onsgmls -p. Please check if onsgmls and the DTD are installed.
You don't need it if you don't want to run the tests.
Text module specific dependencies
This module is used to compute text width; it is needed by AsciiDoc to determine two line titles in encodings different from ASCII. https://github.com/hatukanezumi/Unicode-LineBreak
YAML module specific dependencies
This module is used to parse and serialize the YAML file.
