Add support for fuzzy tag search about ctrlp.vim HOT 42 CLOSED

I was about to post this as well... but thought that someone would implement it, since ctrlp now has support for user extensions (judging by commits)

I already ditched Command-T :D, FuzzyFinder to be next

from ctrlp.vim.

Yup, I've made it very simple to add extensions to ctrlp. Everything you need to know is here.

But I guess it's unlikely that someone will do this, so I'll give it a shot once I have some more free time.

Thanks for the suggestion!

from ctrlp.vim.

Added along with another extension for quickfix. You can enable it with:

let g:ctrlp_extensions = ['tag']

Start in tag mode with :CtrlPTag.

If you find any problem or see anything that can be improved, let me know.

Thanks!

from ctrlp.vim.

I also use EazyTags, and I'd like to leave tag updating to it.
Right now when I start CtrlPTag EasyTags complains that updatetime is set to less than 400.
(I know I can set g:easytags_updatetime_min which would resolve, that but that's not what I want)

Also I don't see any tags if EasyTags is enabled

(Didn't thought this extensions will be ready so soon and so short :) )

Feel free to check my vim config for details:
https://github.com/graudeejs/dot.vim

to install extensions run make in ~/.vim

from ctrlp.vim.

This problem also occurs with tags extension disabled.

from ctrlp.vim.

c3b316a should take care of the updatetime complaint from easytags.

This tag extension only looks for tags files defined with the Vim's tags option. So you'll need to include the name and location of the tags file generated by easytags in this option. Try something like this for your vimrc:

let &tags .= ','.vim_tmp.'/easytags'

from ctrlp.vim.

Yes the issue is solved, but I still don't see tags

Yes tags file is included. But I've set easytags to create tags file for each filetype I edit.
So when I edit ruby my tagsfile is ~/tmp/.vim/eazytags/ruby, when I edit sh it's ~/tmp/.vim/eazytags/sh

I suppose CtrlPTag should check tag file after each time it's invoked (since tags setting is dynamic)

(EasyTags is managing last tags option (path to file))

from ctrlp.vim.

Assuming that the tags option is changed each time you switch to a different filetype, then I think pressing <F5> will update the results. Can you test that and let me know if it helps at all?

from ctrlp.vim.

When I try and launch the :CtrlPTag, the vim process instantly goes to 100% CPU and never loads the tags. I tried with both MacVim snapshot 62 and my MacPorts compiled vim. Here is the console vim version info:

Nope, F5 doesn't help

from ctrlp.vim.

Let know me know how a4b8d4c works?

Thanks!

from ctrlp.vim.

Still nothing... I'll get home and check my config... perhaps I'm missing something...

from ctrlp.vim.

:set tags output:

tags=~/.vim/.git/vim.tags,~/.vim/.git/tags,./tags,./TAGS,tags,TAGS,~/.vimtags,/tmp/.graudeejs/.vim/easytags/vim

(~/tmp is link to /tmp/.graudeejs)
However CtrlPTag show nothing (tagfile is generated)

from ctrlp.vim.

Do :echo tagfiles() and :echo taglist('.*') return anything before and
after running :CtrlPTag? What's the output of :echo tagfiles()?

from ctrlp.vim.

:echo tagfiles() returns ['/tmp/.graudeejs/.vim/easytags/vim']
Which is correct. After running :CtrlPTag output is the same.

:echo taglist('.*') before and after return massive array of
dictionaries with tags

[{'cmd': '/^map ,$ <plug>NERDCommenterToEOL$/', 'static': 0, 'name':
',$', 'language': 'Vim', 'kind': 'm', 'filename': '/home/graudeejs/
.vim/vimrc'},...

I was able to reproduce this by setting path_mode to 0. However, it should
still work with absolute path like
/tmp/.graudeejs/.vim/easytags/vim but somehow doesn't in your case.

I'll investigate further and try to find a fix soon.

I disabled EasyTags (removed plugin) and manyally set tags path to /tmp/.graudeejs/.vim/easytags/vim with

:set tags+=/tmp/.graudeejs/.vim/easytags/vim

and CtrlPTag works.

Btw, I have suggestion:
tagfile might contain duplicates, so you should (somehow) filter these out

from ctrlp.vim.

Let me know how the new commit works. Thanks!

As for filtering duplicates, the :tag command already kind of does this, it
jumps to the first matching tag if there are several ones. Manually
filtering the tags list can be costly, and probably too much for the few
times it actually catches something.

Yey, it works.

Now one more thing:
There should be 2 modes:

1. search tags in current buffer
2. search tags in all buffers (or in entire tagfile)

For second, perhaps it would be good to enter tag name, and then search for file where this tag is. perhaps tag@file format (or should I make new Feature request?)

from ctrlp.vim.

That'll require some non-trivial changes in how ctrlp does the whole pattern matching. Sounds really cool though, so I'll definitely look into it. As for seaching tags in current buffer, it's much more complicated, and I think tagbar and taglist already do it and do it better, so I probably won't make this.

@claytron: Can you let me know how it works for you now?

Thanks!

from ctrlp.vim.

Pretty sweet stuff going on in here! :D

from ctrlp.vim.

I just came to work. I'll work with it for few hours, then I'll let you know...

from ctrlp.vim.

Ok, found a minor problem.

When you work with multiple files, ctrlp caches tags for first file.
When you switch to another file you need to Hit F5 for tags to be updated.

I suggest doing that automatically when CtrlPTag is opened, because it will be annoying as hell to update tags every time I open ctrlp. Also that could prevent CtrlPTag from jumping to wrong line of code, if file was updated (I haven't tested, but I suppose it would jump to wrong line)

I hit a bug..... CtrlPTag can't find tag... when I select any tag and hit Enter it opens Empty buffer saying: "CtrlP: Tag not found."

from ctrlp.vim.

Wow... this happens even if I delete tags file and EasyTags creates new (fresh) one

from ctrlp.vim.

Can you provide steps to reproduce the "Tag not found" error?

For the caching, I'll use something other than just checking for filenames.

from ctrlp.vim.

For sake of environment differences I suggest you take my vim config

git clone https://github.com/graudeejs/dot.vim
cd ~/.vim
make
rm -f ~/tmp/.vim/eazytags/*
vim vimrc

Wait 4-5 seconds for EasyTags to generate tags
now when you open CtrlPTag select tag and press Enter it will show "Tag not found" error.

from ctrlp.vim.

Good idea, I'll try that.

My guess is that easytags changes the results returned by tagfiles() when
switching to a new buffer, hence the tags files are not found when CtrlPTag
trying to run :tag. So there's an option to not create a new buffer/split
or tab (i.e how fuzzyfinder does it).

Anyway, thanks for your time!

It works after last commit

Will do more testing...

from ctrlp.vim.

@kien I don't think it can handle the size of my tags file:

$ wc -l tags 
  144321 tags

I can let it run for a while to see how long it takes to complete. But right now it isn't usable for that many tags.

from ctrlp.vim.

I see. Well, give me a couple of days I'll try adding persistent caching to
this and see if it helps, since the taglist() function seems to be much
slower than readfile().

@kied..... CtrlPTag really needs to show tags of current file by default.

I don't think it would be hard to implement (Need an idea on this?)

from ctrlp.vim.

Sure, I'm listening!

taglist('.*') return list of hashes.
Simple algorithm would be check each element in list.
All you need to check is if filename keys value of each element (hash) match current files name

The result should probably be stored in other list. This would allow to implement quick switching to all tags mode and back to current buffers tags.

I don't think it would be slow, but I'm VimL noob. Anyway, I think user will work with current buffers tags most of the time (also would be good to sort tags by weight according to filename path, similar to how file fuzzy searching is implemented now)

from ctrlp.vim.

Another bug: Currently when you search for tag it show all tags. Now if there are multiple tags with same name but in different files, CtrlPTag can jump to wrong file (even if you manually [with arrow keys] select which tag you want to jump to)

from ctrlp.vim.

@claytron: How does it work for you now? In addition to adding persistent caching, I also remove taglist() altogether and use readfile() for everything.

@graudeejs: That could potentially lead to listing the wrong tags from the wrong file, and would be much slower than using ctags, for example. As for the problem with multiple tags with the same name, tag.vim now uses the tag-matchlist commands as a workaround.

from ctrlp.vim.

It is now showing list of tags and from where they are, and asks me to enter number of tag that I want to open. No good.
http://failiem.lv/thumb_show.php?i=svvoeax&n=not_so_good.jpg

from ctrlp.vim.

It only does that if there's at least one other tag with the same name (there are 2 'index' in your case).

This should be good enough for now, as using the filename to identify the tag isn't reliable.

from ctrlp.vim.

Why not?

Most of time while I work (as Rails programmer) I'll have more >1 tags with same name

from ctrlp.vim.

For people who don't use easytags and have more than one tag file, the filenames can also be the same, as their locations are relative to the tags files.

It's like this:

dir_a
|- file.ext
`- tags (path to file is 'file.ext')

dir_b
|- file.ext
`- tags (path to file is also 'file.ext')

And the tags option:

set tags+=./dir_a/tags,./dir_b/tags

The listing would look like this:

'mytag'    file.ext
'mytag'    file.ext

So unless I'm missing something, there's no easy way out but using tag-matchlist.

from ctrlp.vim.

I see

from ctrlp.vim.

It should be much faster now. I did a few tests with a tags file that has 200000 tags and it seemed to work reasonably well. There are probably a few ugly trade-offs, but at least it loads up in this extreme case.

I also added a tag-count finder, with it you only get the matchlist prompt when the tags are actually identical.

from ctrlp.vim.

Closing this as it's gotten really long and the main issues have been resolved.

Thanks everyone for the feedbacks!

Lastly, just to clarify, you also get the matchlist prompt (see in @graudeejs' screenshot) with :FufTag when jumping to a tag that has duplications. This is the default behavior of :tjump and :stjump. :FufTag just hides the duplications so that you don't know they are there, but if you select one, it'll show that prompt.

So what the tag-count finder does here is it helps switching to the :tag command when possible (differences in path/filename), since the :tag command accepts a count argument. And with this, the prompt only shows up in the rare cases where the duplicate tags have the same filename.
