GScope (Python GTK-3 frontend for CScope)

GScope is a simple GTK-3 frontend for cscope.

It uses ctags or gotags for local symbols lookup while global requests are managed by cscope.

Setup

To setup run sudo python3 setup.py install

Settings format

Settings are kept in json format in form of

{
"img": {
"close": "close.svg",
"locked": "locked.svg",
"unlocked": "unlocked.svg",
"icon": "gscope.svg"
},
"fonts": {
"source": "Droid Sans Mono 13"
},
"tags": {
".*\\.(go)": ["gotags", ["gotags"]],
".*\\.([cChH])": ["ctags", ["ctags", "--excmd=n", "-u", "-f", "-"]],
"*": ["ctags", ["ctags", "--excmd=n", "-u", "-f", "-"]]
},
"ui": {
"source-view-ratio": 0.65,
"tags-view-ratio": 0.20
},
"loglevel": 4,
"editor": ["gvim", "-R"]
}

where img key represent icons, fonts stays for font selection in source code viewer, tags are needed to parse local tags, ui stands for windows splitting ratio, loglevel for debug printouts (from 1 to 4) and editor for launching external editor on Ctl+e keypress inside source code view.

The default settings are shipped with the package itsels but may be overriden with -f path-to-file.json from command line.
