.. _md2po#examples:

Examples
========

::

  md2po -P source-md-dir pot

This will find all Markdown files (.md, .markdown, .txt, .text) in
*source-md-dir*, convert them to POT files (that is, extract all translatable
content) and place them in *pot*.

See the :doc:`pot2po` command for more information about how to create PO files
from the POT files, and to update existing PO files when the POT files have
changed.

Suppose you have created PO files for translation to Xhosa and placed them in
the directory *xh*. You can then generate the translated version of the Markdown
documents like so:

::

  po2md -i xh -t source-md-dir -o xh-md-dir

All the PO translations in *xh* will be converted to Markdown using Markdown
files in *source-md-dir* as templates and outputting new translated Markdown
files in *xh-md-dir*.

Should you prefer a single PO/POT file for your collection of Markdown files,
this is how to do it:

::

  md2po -P --multifile=onefile source-md-dir file.pot

And similarly, to generate multiple translated output files from a single PO
file, invoke po2md like so:

::

  po2md -i xh.po -t source-md-dir -o xh-md-dir

In this example, *xh.po* is the translation file for Xhosa, *source-md-dir* is
the directory where the Markdown files in the source language can be found, and
*xh-md-dir* is the directory where the translated Markdown files will end up.
