Dosn't look like a timeout to me, the error sems to be that i's sending incorrect buffer id for some reason.

[henryoliver]

hi @c0r73x , thanks for replying; the behavior is:

1. Open my vim config file "~/.config/nvim/init.vim" 248L, 7067C

2. Wait 2min without change anything

3. Got the error below:

Very strange error. I will add some exception handling to the part of the code that fails this weekend and try to atleast get some sane error/reason why it crashes.

[henryoliver]

thanks, @c0r73x, appreciate that.

[henryoliver]

hey @c0r73x , did you get a chance to review this issue? I'm getting it every time that I open the vimrc file or the terminal emulator.

Thanks! Henry

[c0r73x]

@henryoliver sorry i've been busy with stuff irl, i will try to get some time soon to debug it.

[henryoliver]

Hey @c0r73x , really appreciate your effort here, thanks!

To be honest I could not figure out how to use this plugin yet, im getting all kind of errors as follow:

Ctags process timed out!

no notification handler registered for ".../.config/nvim/plugged/neotags.nvim/rplugin/python3/neotags:function:NeotagsInit"

I get the correct folder generated, everything seems to look fine, but all of sudden some error appears.

Maybe its something that im doing wrong, can you tell me how can I jump through tags using your plugin, maybe we can start from there, what do you think?

Again, thank you!

[c0r73x]

Humm, what version of ctags are you using?

You jump through them using vims commands, neotags fills vims default tags. https://vim.fandom.com/wiki/Browsing_programs_with_tags

I hope this helps ;)

[henryoliver]

@c0r73x im using:

Every time I try to jump it I get the same message:

Press ENTER or type command to continue

[henryoliver]

Hey @c0r73x , sorry to bother you, but do you have any update on this issue?

I really can't figure out what's wrong with the plugin, so the tag file gets generated inside .vim-tags folder but the plugin never finds it.

Please, let me know if I'm missing anything.

Thanks -- Henry

[c0r73x]

Humm, that's odd. if you run :set tags do the file show up there?

[henryoliver]

@c0r73x the output is: tags=./tags;,tags

Should it point to .vim_tags instead? I'm nothing getting what I'm doing wrong.

Thank you for you help again @c0r73x .

[c0r73x]

Yeah that look incorrect. When neotags has generated new tags for your project it should update the tags variable with a new tagfile. You could try to add it and see if it works, with set tags+=~/.vim_tags/tags

I would recomend running NeotagsVerbosity before you save your file to see if there are any errors.

[henryoliver]

@c0r73x Im suspecting that neovim is not capable to access the bin ctags to generate the tags on the .vim_tags folder:

If I run ctags -R on the terminal it works well.

[c0r73x]

Could you try to set g:neotags_ctags_bin = '/usr/local/bin/ctags'

Looks like the .tag file was created, but I i'm still getting the error below:

Humm i've seen similar issues when using the binary version of neotags 🤔 Other than that i'm out of ideas :(

thats fine @c0r73x i'll just move on. Thanks for your help!
