Plugins/hooks inside ctags pipeline processing
Opened this issue · 1 comments
I wish for being able to annotate tags by their author (from git blame).
How can it be reasonably achieved?
The tags output you expect:
main foo.c /^main(void)$/;" kind:function line:2 blame:john@doe.com
I suppose it's quite possible to do through external wrapper script to annotate tags fed from ctags output.
But can I achive the reverse thing -- plug this script into the middle of ctags pipeline?
Which benefits could it provide comparing with plugging it after ctags?
I strive for most naturally flowing solution.
Interesting idea. I myself want to implement it. However, I have no time.
I would like to write how I will do.
First of all, I think attaching the blame fields should be done in out of u-ctags; implanting a command processing tags file is better.
The command can use readtags.[ch] (https://github.com/universal-ctags/ctags/tree/master/read).
However, you may want to more functions to the API readtags provides.
- a function for writing tags entries, and
- a function attaching an extra field to the data structure representing tag entry.
