Examples

html2po -P site pot

This will find all HTML files (.htm, .html, .xhtml) in site, convert them to POT files and place them in pot.

You can create and update PO files for different languages using the pot2po command. For example, you can create PO files for a translation to Xhosa like this:

pot2po -i pot -t site -o xh

This will merge the POT files in pot into the PO files in xh (if any).

And then, after editing the PO files in xh, you can generate the translated version of the web site like so:

po2html -i xh -t site -o site-xh

All the PO translations in xh will be converted to HTML using HTML files in site as templates and outputting new translated HTML files in site-xh.

Should you prefer a single PO/POT file for your web site, you can create one like so:

html2po -P --multifile=onefile site file.pot

When po2html is invoked with a single PO file as input, and a directory of template HTML files, it will produce one output file per template file. So to generate translated output files from a single PO file, invoke po2html like so:

po2html -i xh.po -t site -o site-xh

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

Notes

The HTML format description gives more details on the format of the localisable HTML content and the capabilities of this converter.

Bugs

Some items end up in the msgid’s that should not be translated
