From 2ca076e45fb3f1c08f6a1a374834df0701b8d778 Mon Sep 17 00:00:00 2001 From: Lewis Russell Date: Thu, 10 Aug 2023 14:21:56 +0100 Subject: feat(treesitter)!: incremental injection parsing Problem: Treesitter highlighting is slow for large files with lots of injections. Solution: Only parse injections we are going to render during a redraw cycle. --- - `LanguageTree:parse()` will no longer parse injections by default and now requires an explicit range argument to be passed. - `TSHighlighter` now parses injections incrementally during on_win callbacks for the line range being rendered. - Plugins which require certain injections to be parsed must run `parser:parse({ start_row, end_row })` before using the tree. --- runtime/lua/vim/treesitter/dev.lua | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'runtime/lua/vim/treesitter/dev.lua') diff --git a/runtime/lua/vim/treesitter/dev.lua b/runtime/lua/vim/treesitter/dev.lua index e94e8f08dc..f7625eb94b 100644 --- a/runtime/lua/vim/treesitter/dev.lua +++ b/runtime/lua/vim/treesitter/dev.lua @@ -99,7 +99,7 @@ function TSTreeView:new(bufnr, lang) -- For each child tree (injected language), find the root of the tree and locate the node within -- the primary tree that contains that root.
