#15 Inverse search


Hello. I'm trying to get the inverse search to work with gedit/latex plugin/xdvi.

Compiling to DVI seems to work OK. Xdvi comes up and does not complain about missing Source Spesials when I CTRL left-click in the DVI file. However, nothing happens when I do so, gedit does not skip to another line in the latex-file.

When trying the dbus-send command manually in an xterm, with an extra --print-reply option, I get the following error message:

dbus-send --type=method_call --print-reply --dest=org.gedit.LaTeXPlugin /org/gedit/DBusInterface org.gedit.LaTeXPluginIFace.inverse string:SNLS2.tex int32:10
Error org.freedesktop.DBus.Python.exceptions.AttributeError: Traceback (most recent call last):
File "/var/lib/python-support/python2.4/dbus/service.py", line 696, in _message_cb
retval = candidate_method(self, *args, **keywords)
File "/home/tmac/.gnome2/gedit/plugins/LaTeXPlugin/ipc/DBusController.py", line 45, in inverse
AttributeError: 'WindowHelper' object has no attribute 'set_active_tab_by_filename'

I'm using Debian Unstable, Latex Pluging v0.1.3.1, gedit v2.20.4-1

Best regards

    I was investigating the same issue and I'd like to add that substituting the dbus-send command with simply 'gedit' makes the inverse search work. Just a temporary hack, I know, but at list it works.

    Hi, here are two patches fixing the problem for me (with LaTeXPlugin- and gedit-2.20.3) with (at least I suppose from the initial code) two features more:
    1) the line corresponding to the point clicked on in the dvi is highlighted in the source, instead of just having the cursor on it;
    2) the gedit window is pulled to the front.

    I don't know if I achieved this the "correct" way, as I'm really new to PyGTK and to LaTeXPlugin, which is definitely not a ten-lines plugin, but at least it works!

    Many thanks to Michael for this really great plugin! It is really useful.

    Best regards,
    Yannick Voglaire
