When I install I get the following on startup:

Error detected while processing VimEnter Auto commands for "*":
E117: Unknown function: NeotagsInit
Press ENTER or type command to continue

And this when I try and run :NeotagsToggle

E117: Unknown function: NeotagsToggle

Neotags generate tags automatically and set tag file into tags variable. but when i echo tagfiles() it's return an empty array (using set tags? it's return tags=./tags;,tags,/tmp/nvim9khncX/75). Using command like :tag tagname neovim says No tags file.

Is i must generate ctags manually or using other plugin for generate ctags ?.
thanks before.

Looks like trying to call UpdateRemotePlugins throws an error.

Seems there is no ctags module to import. Any ideas?

Hi, I stumbled across your project and was curious about how it differs from atags: https://github.com/fntlnz/atags.vim
I'm also trying to find async alternative to easytags.

Hello,

Would it be possible to enable/disable tags highlighting without restarting nvim? Tag highlighting is awesome but it makes vim deadly slow, I'd love to just enable it when i need.

Or maybe it can be done already?

I have installed the requirements (psutils, neovim python client, universal c-tags) but I'm stuck with this error.
I'm on Linux Mint 64 bit.

@roflcopter4 not sure why this happends since the last commit, everything works as it should in C but in JavaScript i get the following error.

I'm not really sure how to debug this, or provide consistent or clear reproduction advice.

Sometimes I noticed that neotags simply doesn't highlight anything. Forcing it off and on again (:NeotagsToggle() twice) fixes it. As does switching to a different buffer and back (sometimes).

I use a lot of split buffers (:vsp etc.), maybe that has something to do with it?

I don't notice anything odd in :messages. I haven't had time to investigate this properly yet.

Today I'm trying to bring some better highlight on my neovim config. Because I really think that could help if this code was more readable:

#define FOO int

FOO test;

Class Foo2 {};

Foo2 test2;

I want to see FOO and Foo2 with some colors, and that's why I wanted to use [neotags][1] (so neotags should be able to resolve this right?)

So why even with let g:neotags_enabled = 1 and the tags file which is generated correctly (I can see define and class), I still don't have colors even when I remove every other plugins?

I have the python3 neovim and psutils packages installed, and I have installed Neotags using vim-plug. On vim startup, I get the message
Error detected while processing VimEnter Auto commands for "*": E117: Unknown function: NeotagsInit
Would you happen to know what might be tripping vim up?

Hi, just install this plugin, and restarted, I get this error :

From a quick look at the code at that line:

    def _parse(self, ft, match_list, groups, languages, ignored_tags, equivalent, order):
        dia.debug_start()
        key_lang = languages[0]

        if key_lang in ('c', 'cpp', 'java', 'go', 'rust', 'cs'):
            buf = strip_c(self.__slurp, dia)
        else:
            buf = bytes(self.__slurp, 'ascii', errors='replace')

        toks = sorted(tokenize(buf, dia))

        for match in match_list:
            if (bindex(toks, match['name']) != (-1)
                    or b'$' in match['name']
                    or b'.' in match['name']):
                key = "%s#%s" % (self.ft, match['kind'].decode('ascii'))
                groups[key].add(match['name'])

        dia.debug_end("Finished _parse, found %d items."
                      % sum(map(len, groups.values())))

It looks like the self.ft should just be ft.

I have a project with a large tags file (wc -l tags -> 8949), and enabling neotags absolutely cripples vim's performance. Even simple tasks such as j/k are slow, and saving (:w) takes a good 5-10 seconds. This makes editing any file almost impossible.

Also, even with a smaller tags file (e.g. just 1-2k tags), it's still noticeably choppier when scrolling around or saving files.

Is there a way to speed up neotags? Other highlighting plugins (e.g. TagHighlight) do not have this issue.

Should there be an option to exclude folders such as .git or node_modules?

Or a setting like this wouldn't make sense?

It seems like neotags.nvim does not work unless neotags itself is in charge of actually generating the tags file. But I don't like the way neoplete generates tags.

The plugin I'm using currently for that, vim-autotag, only updates tags related to the buffer I just saved. So I can manually run ctags to add additional source files, which will not get clobbered by the script. If I try doing the same with neotags, they get removed:

$ ctags -R --extras=+f --fields=\* /usr/include/vulkan .
$ grep -c 'vulkan.h' tags
3736
# save buffer with neotags running
$ grep -c 'vulkan.h' tags
0

It would be great if you could either modify this script to behave more like vim-autotag (thus preserving the existing tags), or alternatively make it possible to combine neotags with vim-autotag somehow (so I can use neoplete for tag highlighting and vim-autotag for tag updating).

Hi,
Thanks for awesome plugin. My issue is that neovim in windows because extremely sluggish when neotags is enabled for big projects. On the other side I dont even see any highlight difference. I assume is because is busy _parseLine() and not done yet. The neotags file that it creates is ~8.8kb. However, if I use the default options:

let g:neotags_ctags_args = [
            \ '-L -',
            \ '--fields=+l',
            \ '--c-kinds=+p',
            \ '--c++-kinds=+p',
            \ '--sort=no',
            \ '--extra=+q'
            \ ]

Then neotags ctags file is created but always with size 0.
This below is my configuration:

Plug 'c0r73x/neotags.nvim' " Depends on pip3 install --user psutil
	let g:neotags_enabled = 1
	let g:neotags_file = g:cache_path . 'neotags'

	let g:neotags_appendpath = 0
	let g:neotags_recursive = 0
	let g:neotags_ctags_bin = 'rg --files -t cpp "'. getcwd() .'" | ctags'
	let g:neotags_ctags_args = [
				\ '-L -',
				\ '--fields=+iaSl',
				\ '--c-kinds=+p',
				\ '--c++-kinds=+p',
				\ '--sort=no',
				\ '--extra=+q'
				\ ]

Thanks for the support

Upon executing :UpdateRemotePlugins, this error appeared:

  File "/Users/amadan/.local/share/nvim/plugged/neotags.nvim/rplugin/python3/neotag

SyntaxError: invalid syntax

I expect this is due to async being a keyword in Python since 3.7.0:

import keyword
keyword.iskeyword('async')
# => True
import sys
sys.version
# => '3.7.0 (default, Jun 29 2018, 20:13:13) \n[Clang 9.1.0 (clang-902.0.39.2)]'

After opening a buffer, all of the highlighted type names etc. end up flickering back and forth between the chosen highlight color and the normal highlighting while neotags is recomputing the highlighting rules.

It flickers back and forth a good 5-10 times or so, and is quite distracting.

• The default for neotags_ctags_args should contain −−extra=[+|−]flags not --extras=[+|-]flags
• I am not able to see any difference, when invoking NeotagsToogle.
  My Config:

let g:neotags_enabled = 1
let g:neotags_ctags_args = [ \ '--fields=+l', \ '--c-kinds=+p', \ '--c++-kinds=+p', \ '--sort=no', \ '--extra=+q', \ ]
let g:neotags_highlight = 1

Work only default highlight for C language.
User-defined types and macroses aren't highlighted.

My config:
let g:neotags_enabled = 1
let g:neotags_highlight = 1
let g:neotags#c#order = 'cgstuedfpm'
let g:neotags#cpp#order = 'cgstuedfpm'

Other plugins:
NerdTree
ctrlp
tagbar

The current highlight rules are rather limiting, compared to what kind of information ctags can actually detect. This file, from TagHighlight.vim (which is what I was using previously until it stopped working) provides a much more complete list:

https://github.com/vim-scripts/TagHighlight/blob/9ee760281ab6e8443ea9bb9ae484b0233b3f0e29/plugin/TagHighlight/data/kinds.txt

It would be great if you could add at least a couple of these to neotags as well.

ModuleNotFoundError: No module named 'neovim.api.nvim'

I'm using Neovim v0.3.1

It looks like the python module was renamed from neovim to pynvim. (see this commit)

cTypeTag etc. are all completely undefined by default, which sort of defeats the purpose of a highlighting engine. (And no, I don't plan on adding this boilerplate for every language in existence to my own .vimrc)

IMO the default should be linked to sane values like cTypeTag -> Type, cFunctionTag -> Function etc..

The way the following is written is unclear to me:

To use the_silver_searcher or similar applications when generating tags you can do something like this.

let g:neotags_appendpath = 0
let g:neotags_recursive = 0

" Use this option for the_silver_searcher
let g:neotags_ctags_bin = 'ag -g "" '. getcwd() .' | ctags'
" Or this one for ripgrep. Not both.
let g:neotags_ctags_bin = 'rg --files '. getcwd() .' | ctags'
let g:neotags_ctags_args = [
\ '-L -',
\ '--fields=+l',
\ '--c-kinds=+p',
\ '--c++-kinds=+p',
\ '--sort=no',
\ '--extras=+q'
\ ]

Is the ctags_args setting applicable to both the ag and the ripgrep setup?

I noticed that the .tags file has a lot of the information found in the .venv folder. Is there a way to exclude it?

After some time I updated all my plugins in neovim and I found that some of the highlights are not working like cType and others

I'm using rakr/vim-one as my colour scheme I don't see any strange change there.
Anyone can point to me what to look for? I'm getting a bit crazy here

If my project heavily relies on identifiers exported by third parties libraries, I would like to be able to add their include directories to my tag list.

On the command line, I can do this with e.g. ctags . /usr/include/foo/. It seems like neotags has no concept of doing this (except perhaps by overriding the ctags arguments itself via a local vimrc or something).

It would be hugely useful if you could allow adding third party directories like this.

Note that I discussed this before in #12, but the recommended solution in that thread (to disable neotags tag generation in favor of other scripts like autotags) no longer works because neotags no longer consults the tags file, instead storing its tags in ~/.vim_tags. So proper support for this in neotags is needed.

Hi guys,

I installed neotags.vim, compiled the binary and added this config in init.vim:

let g:neotags_enabled = 1
let g:neotags_highlight = 1
let g:neotags_run_ctags = 1
let g:neotags_verbose = 1
let g:neotags_recursive = 1
let g:neotags_no_autoconf = 1

For some reason, when starting neovim, I get this error:

Edited - problem still exists

Get this error while starting nvim.
