*mini.cursorword* Autohighlight word under cursor
MIT License Copyright (c) 2021 Evgeni Chasnovski
------------------------------------------------------------------------------
*MiniCursorword*
Features:
- Autohighlight word under cursor with customizable delay.
- Current word under cursor can be highlighted differently.
- Highlighting is triggered only if current cursor character is a |[:keyword:]|.
- Highlighting stops in insert and terminal modes.
- "Word under cursor" is meant as in Vim's |<cword>|: something user would
get as |iw| text object.
# Setup ~
This module needs a setup with `require('mini.cursorword').setup({})`
(replace `{}` with your `config` table). It will create global Lua table
`MiniCursorword` which you can use for scripting or manually (with
`:lua MiniCursorword.*`).
See |MiniCursorword.config| for `config` structure and default values.
You can override runtime config settings locally to buffer inside
`vim.b.minicursorword_config` which should have same structure as
`MiniCursorword.config`. See |mini.nvim-buffer-local-config| for more details.
# Highlight groups ~
*MiniCursorword-hl-groups*
- `MiniCursorword` - highlight group of a non-current cursor word.
Default: plain underline.
- `MiniCursorwordCurrent` - highlight group of a current word under cursor.
Default: links to `MiniCursorword` (so `:hi clear MiniCursorwordCurrent`
will lead to showing `MiniCursorword` highlight group).
Note: To not highlight it, use the following Lua code: >lua
vim.api.nvim_set_hl(0, 'MiniCursorwordCurrent', {})
<
To change any highlight group, set it directly with |nvim_set_hl()|.
# Disabling ~
To disable core functionality, set `vim.g.minicursorword_disable` (globally) or
`vim.b.minicursorword_disable` (for a buffer) to `true`. Considering high
number of different scenarios and customization intentions, writing exact
rules for disabling module's functionality is left to user. See
|mini.nvim-disabling-recipes| for common recipes. Note: after disabling
there might be highlighting left; it will be removed after next
highlighting update.
Module-specific disabling:
- Don't show highlighting if cursor is on the word that is in a blocklist
of current filetype. In this example, blocklist for "lua" is "local" and
"require" words, for "javascript" - "import": >lua
_G.cursorword_blocklist = function()
local curword = vim.fn.expand('<cword>')
local filetype = vim.bo.filetype
-- Add any disabling global or filetype-specific logic here
local blocklist = {}
if filetype == 'lua' then
blocklist = { 'local', 'require' }
elseif filetype == 'javascript' then
blocklist = { 'import' }
end
vim.b.minicursorword_disable = vim.tbl_contains(blocklist, curword)
end
-- Make sure to add this autocommand *before* calling module's `setup()`.
vim.cmd('au CursorMoved * lua _G.cursorword_blocklist()')
<
------------------------------------------------------------------------------
*MiniCursorword.setup()*
`MiniCursorword.setup`({config})
Module setup
Parameters ~
{config} `(table|nil)` Module config table. See |MiniCursorword.config|.

<
------------------------------------------------------------------------------
*MiniCursorword.config*
`MiniCursorword.config`
Defaults ~
>lua
MiniCursorword.config = {
-- Delay (in ms) between when cursor moved and when highlighting appeared
delay = 100,
}
