lsp-document-highlight.nvim

provides you with the power of the textDocument.documentHighlight LSP method in a speedy way

[!TIP]
textDocument.documentHighlight, aka. "cursor word highlighting" or "reference highlighting", is the UI feature where all references to the symbol under the cursor are shown using a highlight.

why does this exist

• instantaneous*, live updating unlike putting vim.lsp.buf.document_highlight() in an autocmd on CursorHold

• no performance issues (configurable lsp call throttling) unlike putting vim.lsp.buf.document_highlight() in an autocmd on CursorMoved

• no flickering (due to slow lsp) when moving within the same symbol unlike any autocmd solution or vim-illuminate

• throttling instead of debouncing so updates trigger immediately when possible unlike snacks.nvim words

• also supports navigating between references (see keymapping below).

*: assuming your lsp is not being slow (*cough* *cough* lua_ls... i've heard typescript lsp is also slow but :shrug: not something i use)

installation

consult your favorite plugin manager.

this plugin loads itself -- no need to call any setup function.
this plugin is self-lazy-loading. (although setup() currently triggers loading... but there's so little code anyway)

configuration

see config.lua for the defaults and types.lua for annotations on what the keys mean.
if you have lua_ls set up, you can also enjoy autocompletion and hover documentation in your plugin config if you annotate the table with the LDH.config type.

example setup with keymaps to navigate references (using lazy.nvim):

---@type LazySpec
return {
  {
    "akioweh/lsp-document-highlight.nvim",
    lazy = false,
    keys = {
      {
        "[[",
        function()
          require("lsp-document-highlight").jump(-vim.v.count1, true)
        end,
        desc = "Previous Reference",
      },
      {
        "]]",
        function()
          require("lsp-document-highlight").jump(vim.v.count1, true)
        end,
        desc = "Next Reference",
      },
    },
    ---@type LDH.config
    opts = {
      throttle = 50,
    },
  },
}

[!TIP]
passing vim.v.count1 into jump allows one to naturally use vim keycounts to jump multiple references at once.

lua api

the module is called lsp-document-highlight. require it to access all the public functions (see the code ).

the only thing of interest now is the require("lsp-document-highlight").jump(count, wrap) function:

--- jumps to the next count-th (or previous if negative) reference
--- @param count number
--- @param wrap? boolean definitely self-explanatory
function M.jump(count, wrap)
  -- ...
end

[!NOTE]
if count is more than 1 (negative or positive), jumping will never wrap around. this, with a keymap setup like above, makes [[ and ]] only wrap when a keycount is NOT given; any large enough keycount will get you to the first or last reference instead of sending you somewhere random due to wrapping.

call .enable() or .disable() to do what the function names suggest.
you can also do this per-buffer by passing a filtering predicate to the enable.buffer key in the config. i recommend storing a flag in vim.b[] and have the predicate check the flag :).

PS. star pls :)
