vim-tag-peek

A neovim plugin for peeking at tag definitions using the nvim_open_win "floating window" feature.

Usage

Assuming you have installed this plugin and have ctags properly setup, map a command to peek at the tag under the cursor

nnoremap <leader>q :call tag_peek#ShowTag()<CR>

You can also invoke the function directly to view a specific tag definition. e.g. to view the tag delete you could do :call tag_peek#ShowTag("delete")

Preview Mappings

Unless you opt-out of mappings (via let g:tag_peek_mappings=0), the following normal-mode key mappings will be setup for the preview window:

key	behavior
q	Close the preview window
<c-n>	Jump to the next definition of the tag
<c-p>	Jump to the previous definition of the tag
<c-e>	Edit the currently previewed file in a split

Configuration

This plugin aims to have reasonable defaults but a few configuration variables are provided for power-users.

variable	usage
g:tag_peek_mappings	set to 0 to opt-out of the default preview mappings
g:tag_peek_split_command	control how a split is opened from the preview window (this is vsplit by default but you might prefer split or tabnew)
g:tag_peek_float_config	set this to a custom function name to control the config passed to control the display of the preview window. See below for an example and :help nvim_open_win for more info.

Example g:tag_peek_float_config usage:

function! MyFloatConfig()
  return {
        \ 'relative': 'editor',
        \ 'row': 10,
        \ 'col': 10,
        \ 'width': 80,
        \ 'height': 20
        \ }
endfunction

let g:tag_peek_float_config="MyFloatConfig"
