L10N/Typo Purification of po Files

This page is a work in progress.

This page describe and explains how to setup and use a python tool that aims at detecting typographic fault in translation files.

Description of the tool

This tool is a python script that can be found at https://github.com/jaaf/po_purifier. It scan a directory for .po files. For each file, it checks translated messages against typographic rules that reside in a configuration file nammed typorules.py. Each time a typographic rule is not satisfied, the program stops and ask the user what to do. The figure 1 below shows how it looks like :

Figure 1: Typographic Fault Detected

• The message to the user, that appears in English here, normally appears in the user's language, provided that the program has been localized. It has 2 parts:
  • The first part that tells the user a typo rule is infringed and that he has to decide for change or not (it is part of the program and has to be localized)
  • The typo rule itself (it belongs to the typorules.py file)

• In this case the French typo rule requires a narrow no break space between a value and its unit and the location of the fault is shown with a green highlight.

• To help the user, the message is shown twice. First with the various spaces colorized according to their type then with the typo fault highlighted.
