From 54d6a32fbdcbd5b26b72f4dca8906e60f5186d2c Mon Sep 17 00:00:00 2001 From: Christian Clason Date: Mon, 12 Dec 2022 20:43:14 +0100 Subject: feat(lsp): highlight semantic token modifiers (#21390) Apply semantic token modifiers as separate extmarks with corresponding highlight groups (e.g., `@readonly`). This is a low-effort PR to enable the most common use cases (applying, e.g., italics or backgrounds on top of type highlights; language-specific fallbacks like `@global.lua` are also available). This can be replaced by more complicated selector-style themes later on. --- runtime/lua/vim/lsp/semantic_tokens.lua | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) (limited to 'runtime/lua/vim/lsp') diff --git a/runtime/lua/vim/lsp/semantic_tokens.lua b/runtime/lua/vim/lsp/semantic_tokens.lua index f06d136801..b7ffedab2b 100644 --- a/runtime/lua/vim/lsp/semantic_tokens.lua +++ b/runtime/lua/vim/lsp/semantic_tokens.lua @@ -409,7 +409,17 @@ function STHighlighter:on_win(topline, botline) strict = false, }) - --TODO(jdrouhard): do something with the modifiers + -- TODO(bfredl) use single extmark when hl_group supports table + if #token.modifiers > 0 then + for _, modifier in pairs(token.modifiers) do + api.nvim_buf_set_extmark(self.bufnr, state.namespace, token.line, token.start_col, { + hl_group = '@' .. modifier, + end_col = token.end_col, + priority = vim.highlight.priorities.semantic_tokens, + strict = false, + }) + end + end token.extmark_added = true end @@ -494,7 +504,7 @@ local M = {} --- opt-out of semantic highlighting with a server that supports it, you can --- delete the semanticTokensProvider table from the {server_capabilities} of --- your client in your |LspAttach| callback or your configuration's ---- `on_attach` callback. +--- `on_attach` callback: ---
