Add Option to Ignore Declaration Tags about vim-gutentags

[justinmk]

You can configure ctags however you like, via the .gutctags in particular. There is no need for numerous plugin options. taglist.vim tries to do far too much, and it doesn't work very well.

Thanks for the kind words, and the name was sadly not my idea (follow the Reddit link... but I wish I thought about it!)

Yep, @justinmk is right, unless I'm misunderstanding your problem, you can create a .gutctags at the root of your project and specify what you want (probably using --pascal-kinds options and such... see the ctags documentation).

I did check in ctags -- list-kinds but, of the 41 languages supported by ctags, only 3 (VHDL, Perl, SML) specify a declaration "kind", which could be switched off.

So in the chain of "Ctags -> GutenTags -> CtrlP" I supposed that the most suitable link to implement my proposed feature is GutenTags, because "taglist.vim" did it (and I replaced this plugin with GutenTags). Every IDE I used also didn't show the function declarations in the Code Structure/Navigation panel, so I'm not crazy :P

Maybe there could be a hook once the tags file is generated to sort the tags file, and delete the "duplicate" functions?

[ludovicchabant]

Mmmh I'm confused, are you using some custom filter with taglist.vim, or does it somehow remove those "duplicates" automatically? I tried disabling Gutentags and installing taglist.vim and I see both entries for each function on a Pascal codebase in the TlistOpen window (and actually I don't know about Pascal but in C++ I definitely want to see both declaration and implementation in the tag list).

[dbedrenko]

Damn, you're right. Sorry about that oversight, I messed up.

But is it still possible to have a hook in place after the tags file has been written to filter and re-process the tags file according to some custom rules (I will manipulate it with regexps and with sorting)? It would make this plugin a lot more extensible.

Something like g:gutentags_custom_commands that points to an executable file and runs wherever the tags file is stored.

I don't know C++, but in Obj Pascal almost all functions have a declaration line exactly like the definition line (rarely, a directive like "overload" is added which is included only in the declaration). So the only time you want to go to the declaration is if you're changing it, which is a rare occurence.

I suppose some option to run custom processing would be useful, yeah... you can send a pull request if you're up to it :) Otherwise I'll try writing up something when I get some free time, but this will likely be low priority for me.

[ludovicchabant]

Well obviously I don't have enough free time these days to implement this kind of feature, especially since I would not use it myself. Anybody's free to send a pull request though :)
