From 688b961d13bd54a14836f08c3ded3121d3fb15a0 Mon Sep 17 00:00:00 2001 From: Lewis Russell Date: Fri, 19 Apr 2024 16:04:57 +0100 Subject: feat(treesitter): add support for wasm parsers Problem: Installing treesitter parser is hard (harder than climbing to heaven). Solution: Add optional support for wasm parsers with `wasmtime`. Notes: * Needs to be enabled by setting `ENABLE_WASMTIME` for tree-sitter and Neovim. Build with `make CMAKE_EXTRA_FLAGS=-DENABLE_WASMTIME=ON DEPS_CMAKE_FLAGS=-DENABLE_WASMTIME=ON` * Adds optional Rust (obviously) and C11 dependencies. * Wasmtime comes with a lot of features that can negatively affect Neovim performance due to library and symbol table size. Make sure to build with minimal features and full LTO. * To reduce re-compilation times, install `sccache` and build with `RUSTC_WRAPPER= make ...` --- src/nvim/lua/executor.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'src/nvim/lua/executor.c') diff --git a/src/nvim/lua/executor.c b/src/nvim/lua/executor.c index 4d5b2c3698..d4940f3add 100644 --- a/src/nvim/lua/executor.c +++ b/src/nvim/lua/executor.c @@ -924,6 +924,7 @@ void nlua_free_all_mem(void) lua_State *lstate = global_lstate; nlua_unref_global(lstate, require_ref); nlua_common_free_all_mem(lstate); + tslua_free(); } static void nlua_common_free_all_mem(lua_State *lstate) @@ -1902,8 +1903,13 @@ static void nlua_add_treesitter(lua_State *const lstate) FUNC_ATTR_NONNULL_ALL lua_pushcfunction(lstate, tslua_push_querycursor); lua_setfield(lstate, -2, "_create_ts_querycursor"); - lua_pushcfunction(lstate, tslua_add_language); - lua_setfield(lstate, -2, "_ts_add_language"); + lua_pushcfunction(lstate, tslua_add_language_from_object); + lua_setfield(lstate, -2, "_ts_add_language_from_object"); + +#ifdef HAVE_WASMTIME + lua_pushcfunction(lstate, tslua_add_language_from_wasm); + lua_setfield(lstate, -2, "_ts_add_language_from_wasm"); +#endif lua_pushcfunction(lstate, tslua_has_language); lua_setfield(lstate, -2, "_ts_has_language"); -- cgit
