ripper-tags issue

[smileart]

Hi. Trying to use vim-gutentags on Ruby project with these settings:

" =================== VimGutentag ===================
let g:gutentags_define_advanced_commands = 1
let g:gutentags_ctags_executable_ruby = 'ripper-tags'

Thanks to :GutentagsToggleEnabled I've got a log file wich states roughly the next:

Locking tags file...
Running ctags on whole project
ripper-tags -f "tags.temp"  --options=/Users/usernamehere/.vim/bundle/vim-gutentags/res/ctags.options --exclude=*.~ --exclude=*.o --exclude=*.obj --exclude=*.pyc --exclude=.sass-cache --exclude=tmp "."
ripper-tags: invalid option: --options=/Users/usernamehere/.vim/bundle/vim-gutentags/res/ctags.options

Using: ripper-tags 0.3.3 (there is no --options option, at least in the help) in vim 7.4.899 and ruby 2.2.4p230

Hi!

You're not the first one to ask about ripper-tags so I figured I would go take a look at it, and sadly I don't think it can work as-is. Even if gutentags was not passing stuff like --options that ripper-tags doesn't support, the main problem is that it doesn't support --append either (or anything like it for what I can see). That's required to be able to only update the current file when you edit something and save (instead of re-indexing the whole project every time).

I think what needs to happen is that (1) ripper-tags needs to support something like --append and --options to be able to act as a true stand-in to ctags, OR (2) Gutentags would need to be aware of ripper-tags and have special code paths for it to emulate --append -- which is not ideal.

Frankly at this point, since I personally don't code in Ruby, I'm not going to do much about it except look at any good looking patch to solve this. My advice to anybody who needs this is to make Gutentags run a ripper-tags-wrapper script that would:

1. skip stuff like --options
2. emulate --append by running ripper-tags on the single provided file path, but output it into a temporary tags file, which is then appended to the "real" temp tags file, and then sorts that file by symbol order (like ctags does).

I would be ok shipping this wrapper script with Gutentags if anybody wrote it.

Hi @ludovicchabant,

Thanks for your detailed reply! Now I see that this is not vim-gutentags issue at all. Moreover, I found out that these things are already being discussed on ripper-tags issues (like this or this). Thanks again!

Take a look at ripper-tags --ignore-unsupported-options

Fixed in ripper-tags 0.8.0.

let g:gutentags_ctags_executable_ruby = 'ripper-tags --ignore-unsupported-options --recursive'

In case anyone else runs into issues, the latest changes with vim-gutentags requires you to pass in additional arguments as such:

let g:gutentags_ctags_executable_ruby = 'ripper-tags'
let g:gutentags_ctags_extra_args = ['--ignore-unsupported-options', '--recursive']
