I am trying to run gtags on a python code base with a pygments plug-in parser, but the GTAGS file produced is empty and the GRTAGS references stuff like "str" which just seems wrong to me.
Here are relevant parts of the .globalrc:
default:\
:tc=native:tc=pygments:
pygments:\
:tc=pygments-parser:tc=htags:
and pygments-parser is pretty straightforward, I guess. Global is version 6.6.2. I have read this might be a problem with ctags, which pygment uses for definition tags, however gtags --explain does not mention any usage of ctags - should it? The .globalrc does not specify any configuration of ctags, but judging by the pygments plug-in manual this should not be necessary as pygments uses it internally. Is that correct? What could be the cause
I also use global (GNU GLOBAL) 6.6.2. I don't have my own
.globalrc. The following method described in
/usr/share/gtags/PLUGIN_HOWTO.pygments works for me:
$ export GTAGSCONF=/usr/share/gtags/gtags.conf
$ export GTAGSLABEL=pygments
$ gtags
$ ls -Al G*
-rw-r--r-- 1 ja users 32768 May 28 22:22 GPATH
-rw-r--r-- 1 ja users 458752 May 28 22:22 GRTAGS
-rw-r--r-- 1 ja users 253952 May 28 22:22 GTAGS
After doing that I can use gtags
mode
inside Emacs to jump to a function definition and calls.
EDIT: I checked that in order for this to work I need to have a working ctags binary in my $PATH, it's also described in the help file I mentioned:
Make sure python and ctags can be invoked in your command line.
$ type python
python is /usr/bin/python
$ type ctags
ctags is /usr/local/bin/ctags
