fix(lua): pop retval for fast context LuaRef

2025-01-24T10:57:51+00:00

Problem:  nlua_call_ref_ctx() does not pop the return value in fast
          context that did not error.
Solution: Fall through to end; calling nlua_call_pop_retval().

fix(lua): prevent SIGSEGV when lua error is NULL in libuv_worker

2025-01-18T19:08:50+00:00

Problem:
Calling `xstrdup` with a NULL pointer causes a SIGSEGV if `lua_tostring` returns
NULL in `nlua_luv_thread_common_cfpcall`.

Crash stack trace:
- `_platform_strlen` → `xstrdup` (memory.c:469)
- `nlua_luv_thread_common_cfpcall` (executor.c:281)

Solution:
Check if `lua_tostring` returns NULL and pass NULL to `event_create` to avoid the crash.

feat(api): add err field to nvim_echo() opts

2025-01-09T12:35:40+00:00

Problem:  We want to deprecate `nvim_err_write(ln)()` but there is no
          obvious replacement (from Lua). Meanwhile we already have
          `nvim_echo()` with an `opts` argument.
Solution: Add `err` argument to `nvim_echo()` that directly maps to
          `:echoerr`.

refactor: iwyu #31637

2024-12-23T13:43:52+00:00

Result of `make iwyu` (after some "fixups").

fix(messages): proper multiline Lua print() messages #31205

2024-11-17T18:21:50+00:00

Problem:  Separate message emitted for each newline present in Lua
          print() arguments.
Solution: Make msg_multiline() handle NUL bytes. Refactor print() to use
          msg_multiline(). Refactor vim.print() to use print().

fix(messages)!: vim.ui_attach message callbacks are unsafe

2024-11-14T12:23:11+00:00

Problem:  Lua callbacks for "msg_show" events with vim.ui_attach() are
          executed when it is not safe.
Solution: Disallow non-fast API calls for "msg_show" event callbacks.
          Automatically detach callback after excessive errors.
          Make sure fast APIs do not modify Nvim state.

fix(lua): show stacktrace for error in vim.on_key() callback (#31021)

2024-11-02T02:11:06+00:00

feat(lua): allow vim.on_key() callback to consume the key (#30939)

2024-11-01T01:11:15+00:00

fix(lua): avoid recursive vim.on_key() callback (#30753)

feat(treesitter): add support for wasm parsers

2024-08-26T14:44:03+00:00

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 ...`
