wxWidgets XRC Ampersands Checker

This is Python 3.2 script which tries to detect conflicts in keyboard shortcuts on dialogs, panels, menus etc. Although they don't need to be unique it's better if they are. Note that this tool can check only those parts of dialogs which are defined in XRC files, it cannot check conflicts with parts generated at runtime by the application. I only tested it with FileZilla, but theoretically it should work with any application which is based on XRC and gettext.


  1. Python 3.2.
  2. MO file with your translation. It makes sense to test only fully completed translation.
  3. XRC files. These files contain dialogs definitions. They are distributed as a part of FileZilla sources. They should correspond to filezilla.pot you've used to update yours PO file. If you are using POT from the FileZilla's Translation page then download newest Source snapshot from the Nightly Builds page. Unpack the sources somewhere. The locales\filezilla.pot file should be the same as the POT file from the Translations page you've used. (If not use it for updating PO file.) XRC files should be in the src\interface\resources directory.


  1. Download Ampersands Checker and unpack it somewhere.
  2. (Windows) If you are not going to run Ampersands Checker from command prompt window and you've not installed Python into C:\Python32 update the amps_checker.bat accordingly.
  3. Edit the config.txt, see comments in that file to configure it properly.


  1. Run amps_checker.bat (or amps_checker.py if you are in the command line or shell). If no error happened then you should find the results in the output file specified in config.txt.
  2. Results should look like this:
    Processing dialog dialogs.xrc wxDialog ID_COLUMN_SETUP Column setup
    Processing dialog dialogs.xrc wxDialog ID_MANUALTRANSFER Manual transfer
        String "Sou&bor:" and "Způso&b přihlašování:" contains same shortcut!
        String "S&erver" and "Úč&et:" contains same shortcut!
        Used characters on this dialog: b d e h l m o p r s u v y z
    This means that no conflicts were found in the dialog "Column setup" and two conflicts were found in the "Manual transfer" dialog. It also tells you which characters are already in use so you know which are free to use.


This simple Python 3.2 script replaces lines like
#: resources.h:775
in the PO file with lines like
#line 525 "./settings.xrc"
sou you can look inside the XRC file for the context of translated message. This script takes two arguments: resource.h and the PO file. It writes results to the file with same name as the PO file + ".out". How to get resource.h? Download FileZilla sources (must be the exactly same version as was used for generating POT file which was last time used for updating PO file or the line numbers won't match). Unpack them and in the directory with XRC files (see above) run:
wxrc /g /o resource.h *.xrc
wxrc is part of the wxWidgets. Precompiled Windows binary is part of the resh2xrc_line_no package.

Patch for poEdit

This is my experimental patch against poEdit git which adds option for ignoring ampersands in the messages when sorting. (So &b is placed between a and c.) Sorry, no binaries.
