I'm looking for a way to define or view and modify which characters are considered word boundaries by GNOME, similar to the "select-by-word" characters used in GNOME Terminal (related question) or cutchars in rxvt.

For example, when I am using gedit I can type abc123xyz and double-click, but only three characters will be selected, since the numbers are treated as a boundary by default. I see the same behavior in Tomboy, and at least a few other other GNOME/GTK+ applications I've tested. It's also present--and particularly annoying--inside the location bar (but not inside pages) of Google Chrome. Firefox seems OK, I believe since its UI is written in XUL, which is doing its own thing.

Please note that I am looking for a general solution, if one exists--I already know that there are plugins for gedit in particular, and maybe other per-application tweaks, but I want to know if this can be done in a way that affects most or all programs that inherit this behavior from the window manager (I presume?).

Please also let me know if you can't reproduce this behavior. If that's the case, I suspect it may have something to do with locales.. I'm on Debian wheezy, using GNOME 3, en_US.UTF-8 locale (sometimes fr_FR.UTF-8). –  Noyo Sep 26 '13 at 9:35
    
More research hints that it's maybe not locale-related, but rather a well-established mystery related to the way (all?) Gtk+ applications seem to behave by default: mail.gnome.org/archives/gtk-list/2011-June/msg00060.html and mail.gnome.org/archives/gtk-i18n-list/2011-June/msg00003.html –  Noyo Sep 26 '13 at 13:31

Apparently, this was fixed in version 1.34.1. Check the git log and the commits between 1.34.0 and 1.34.1 tags. Ubuntu 13.04 has version 1.32.5 of libpango1.0-0 same as sid. So, no joy for now for Debian-based distributions. If you need the library, you may compile it from sources.

This is an issue with the PangoLogAttr() function that seems that nobody has reported a bug complaining about it. The issue goes back to 2003 till the current time. Appart of the mails that you supply there are:

If my interpretation of the guidelines is correct, then it's expected that a word containing numbers, the word is limited by the numbers the same that by spaces and symbols except the '.

Good research, thanks! Strange, though, that even the example given in the guidelines doesn't follow the default of having . as a boundary.. In any case, it may be more of a feature request than a bug. Can you include a link to where one might file a bug? –  Noyo Oct 2 '13 at 14:50
    
Thanks again! After some quick searching, it does look like people want this and have indeed filed bugs/feature requests: bugzilla.gnome.org/show_bug.cgi?id=111503 and bugzilla.gnome.org/show_bug.cgi?id=530427 and bugzilla.gnome.org/show_bug.cgi?id=97545 at least. Maybe I'll just follow/comment on one of those for now. –  Noyo Oct 2 '13 at 16:39
    
Actually, according to that last one, a fix for my specific "abcc123" example has been committed: bug97545.bugzilla-attachments.gnome.org/… . No idea though when that version makes it to my Linux distro. –  Noyo Oct 2 '13 at 16:52
    
It is merged, but it's much more recent than the link in your comment. See here: git.gnome.org/browse/pango/commit/pango/… . Now sure if that version is included in any stable version of a Linux distro at the moment. –  Noyo Oct 2 '13 at 17:34
    
@Noyo any reason to no accept the answer? –  Braiam Oct 4 '13 at 12:45
