# vim-lookup

This plugin is meant for VimL programmers. It jumps to definitions of variables,
functions, and commands as if tags were used, without needing a tags file. It simply
uses your [runtimepath](https://neovim.io/doc/user/options.html#'rtp').

- [x] `s:var`
- [x] `s:func()`
- [x] `<sid>func()`
- [x] `autoload#foo#var`
- [x] `autoload#foo#func()`
- [x] `'autoload#foo#func'`
- [x] `Command`

Sometimes a function `foo#func()` is not found in `autoload/foo.vim` but
`plugin/foo.vim`. This case is handled as well.

It also works for global functions if they're defined or found in the current
file:

- [x] `GlobalFunc()`
- [x] `g:GlobalFunc()`

### Usage

- Use `lookup#lookup()` to jump to the defintion of the identifier under the
  cursor.
- Use `lookup#pop()` (or the default mapping
  [`<c-o>`](https://github.com/mhinz/vim-galore/#changelist-jumplist)) to jump
  back.

### Configuration

```viml
autocmd FileType vim nnoremap <buffer><silent> <cr>  :call lookup#lookup()<cr>
```

Alternatively, you can replace the default mappings Vim uses for
[tagstack](https://neovim.io/doc/user/tagsrch.html#tag-stack) navigation:

```viml
autocmd FileType vim nnoremap <buffer><silent> <c-]>  :call lookup#lookup()<cr>
autocmd FileType vim nnoremap <buffer><silent> <c-t>  :call lookup#pop()<cr>
```
