Vim plugin for automatically highlighting other uses of the word under the cursor using either LSP, Tree-sitter, or regex matching. Think nvim-cursorword, vim-cursorword, or nvim-cursorword, but better.

Min Neovim Version: v0.7.2

Migration Guide

Remove any vim-illuminate configuration from your init file, simply having the plugin installed will load it and start highlighting the buffers using one of LSP, Tree-sitter, or regex matching (in that order) depending on which is available.

If you don't care to use the latest and greatest, then add let g:Illuminate_useDeprecated = 1 (or vim.g.Illuminate_useDeprecated = 1 for Lua configs) to your init file and everything will continue to work the same as before.

If you have any require('illuminate').on_attach() lines in your config currently, you can remove them since the it now finds the LSP dynamically. Leaving that line in your config is fine too, it'll just cause existing behaviour to be used instead.

You may need to update your highlight groups to use IlluminatedWordText, IlluminatedWordRead, and IlluminatedWordWrite.

More than just highlighting

You can now use <a-n> and <a-p> to jump around the references.

You can also use <a-i> as a textobject for the reference under the cursor.

Full configuration

-- default configuration
require('illuminate').configure({
    -- providers: provider used to get references in the buffer, ordered by priority
    providers = {
        'lsp',
        'treesitter',
        'regex',
    },
    -- delay: delay in milliseconds
    delay = 100,
    -- filetypes_denylist: filetypes to not illuminate, this overrides filetypes_allowlist
    filetypes_denylist = {
