I just released translation-filter 0.3. You can download it from here.
The scope of development is to create a rudimentary tool that can allow comparing the quality of string translations in an offline mode. For example, the KDE Project uses a web based tool that allows strings to be searched in translated content.
The current set of requirements for this offline tool are:
It uses PyQt4 for the gui, used QWebView to render the result. You will also require translate-toolkit (at least 1.0.1 version, available in Fedora 9).
Among the new features (mostly in the command line version) , using -t or –term you can search for any single term. You can even check for unattached dependent vowel signs of Indic languages using -d option.
