* docs(help): specify h4 "function signature" format #42434masterJustin M. Keyes3 days
| | | | | | | | | | | | | | | | | | | | | Work towards enabling ["flow" layout](https://github.com/neovim/neovim/blob/9244da12e400ec0291450a5e9400d995e7a29b83/src/gen/gen_help_html.lua#L86-L88) in all `:help` files. Problem: The final boss of vimdoc pseudo-structure: Vim's quasi-headings on function signatures and excmd docs is visually distinctive but too inconsistent for a nice parse rule. Solution: - Define the quasi-heading format as an "h4" variant, specified at `:help help-tag-heading`. - For simplicity and predictability, it is defined as any line that ends with a help tag(s) preceded by 2 or more spaces (or 1 tab). - Update existing docs. - This one-time update has a lot of changes, but is very unlikely to conflict with ported Vim-patches because (1) Vim rarely adds new *excmds* that we want, and (2) *function* docs are auto-generated. ref https://github.com/neovim/tree-sitter-vimdoc/issues/110
* ci(lua): enable annotation and style checksLewis Russell2026-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: - annotation-usage-error and code-style-check are disabled. - vim.inspect relies on a dummy self-assignment for docgen, and its help omits parameter and option details. - LuaLS fallback types obscure iterator inference. - Docgen hardcodes public function names and appends separately sorted files, leaving shared helpers under the inspector heading. Solution: - Enable annotation-usage-error and code-style-check, and fix misplaced annotations. - Document vim.inspect's callable module directly, removing the dummy assignment. Describe its parameters, option defaults and process callback. - Remove LuaLS iterator fallbacks, correct iterator signatures and check values that the improved inference identifies as optional. - Parse callable modules, require bindings and parent module references. Derive public names and inherited function docs from these links, including missing help for vim.async.semaphore() and vim.version(). - Export vim.lsp.tagfunc directly with lazy loading and document its implementation instead of maintaining a wrapper. - Group files in section_order, replacing append_only and merge_files. Merge declarations before sorting each section, placing shared helpers in the main vim section and keeping vim.inspect in alphabetical order. - Add basic parser coverage for callable modules and module links.

* feat(lua): add vim.asyncLewis Russell2026-09-03
Problem: Nvim has many Lua APIs that start callback-driven work: timers, jobs, libuv handles, and other event-loop tasks. Callers that need to sequence or cancel that work have to build their own coroutine wrappers, task bookkeeping, and cleanup rules. This makes async control flow hard to share, test, and document. Solution: Add `vim.async`, a structured-concurrency module vendored from async.nvim. It provides task handles, await/pawait helpers, sleep/timeout helpers, completion-order iteration, and semaphores on top of Nvim's event loop. The API follows the same broad model as Trio: async work has an owner, tasks are awaited explicitly, and cancellation is cooperative. Include generated vimdoc with an introductory overview and examples, a news entry, and functional tests for the new module. AI-assisted
