VIM set ctags in .vimrc

vim ctags

Solution 1

That is because the current directory of vim is the home directory. You either need to change the path or create nerdtree plugin. See nerdtree_plugin directory for an example. I think that you'll find this function interesting:

g:NERDTreeFileNode.GetSelected()

Solution 2

Functions are supposed to start with a capital letter. Change createTags to CreateTags.
To use project-specific tags files you will need to add something like that to your .vimrc:
```
set tags=./tags,tags;
```
so that Vim looks for a tags file in the current directory first and up and up until it finds it. Additionnaly, I like to set autochdir: the working directory is always the one containing the current file.

I have my projects in /srv/http/dev folder. I generated ctags file for one project:
```
$ ctags -R --languages=php .
```
Now I set ctags path:
```
:set tags=/srv/http/dev/proj/tags
```
And it's working fine.

But I have many projects in dev/ folder. How can I set ctags in .vimrc file? set tags=tags not working properly.

And I would like to generate tags file by pressing hotkey on selected NERDTree folder. I tried:
```
nmap <silent> <F4>
    \ :!ctags -R
    \ --languages=php .<CR>
```
But it creates tags file in home folder and shows warnings about scanning home folder..

EDIT: As @Alexandru Plugaru advised I should use g:NERDTreeFileNode.GetSelected() function.

I am just newbie vim user, so I have one more question. I have added in my .vimrc file:
```
function createTags()
    let curNodePath = g:NERDTreeFileNode.GetSelected().path.str
    exec ':!ctags -R --languages=php ' . curNodePath
endfunction
nmap <silent> <F4> :execute createTags()<CR>
```
But by pressing on F4 I see:
```
E117: Unknown function: createTags
E15: Invalid expression: createTags
```
EDIT 2: Thanks to @Alexandru Plugaru I got this:
```
function CreateTags()
    let curNodePath = g:NERDTreeFileNode.GetSelected().path.str()
    exec ':!ctags -R --languages=php -f ' . curNodePath . '/tags ' . curNodePath
endfunction
nmap <silent> <F4> :call CreateTags()<CR>
```
And it works! By pressing F4 I get tags file in project folder.

  try :call createTags() also try naming the function with a capital letter.

Thanks, I think it is what I need. Can you answer on more question please? See my EDIT.

Ok, it's works. But what about more one projects. After creating new project I must add full path to this new project? And so again and again? May be it can be automated?

I understand what you mean, but I can't understand how to do it) I added set tags=./tags,tags and set autochdir in my .vimrc file. But tags not founded because vim starts to find them from /home..

Vim starts from home because it's probably the working directory. What does :pwd says?

Oh, I'm sorry) I forgot semicolon after set tags=./tags,tags. Thank you very much!

using ./tags; as mentioned in another answer is highly preferable to hard-coding paths in .vimrc.

Is the semicolon behavior documented anywhere? It's not mentioned in :help 'tags'.

you could also use github.com/embear/vim-localvimrc to have a "local vimrc" per project where you define different tags.
