PROBLEM: `vim.treesitter.get_node()` does not recognize the `lang` in
the option table. This option was used in somewhere else, for instance,
`vim.treesitter.dev` (for `inspect_tree`) but was never implemented.
SOLUTION: Make `get_node()` correctly use `opts.lang` when getting a
treesitter parser.
* docs(lua): teach lua2dox how to table
* docs(lua): teach gen_vimdoc.py about local functions
No more need to mark local functions with @private
* docs(lua): mention @nodoc and @meta in dev-lua-doc
* fixup!

Problem:
"playground" is new jargon that overlaps with existing concepts:
"dev" (`:help dev`) and "view" (also "scratch" `:help scratch-buffer`) .
Solution:
We should consistently use "dev" as the namespace for where "developer
tools" live. For purposes of a "throwaway sandbox object", we can use
the name "view".
- Rename `TSPlayground` => `TSView`
- Rename `playground.lua` => `dev.lua`
Problem:
Codebase inconsistently binds vim.api onto a or api.
Solution:
Use api everywhere. a as an identifier is too short to have at the
module level.
Problem:
vim.treesitter.inspect_tree() and :InspectTree does not respect 'splitright'.
Solution:
- Change the default `command` from `topleft 60vnew` to `60vnew`.
- Change :InspectTree to respect command mods (`:vertical`, count, etc.).
Closes#22656
When toggling anonymous nodes in the :InspectTree window, keep the
cursor fixed relative to the node within the tree. This prevents the
cursor from jumping.
Problem:
"show" is potentially a new verb that we can avoid (there is already
"open" and "echo"). Even if we can't avoid it, the behavior of
`show_tree` fits well in the "inspect" family of functions: a way for
users to introspect/reflect on the state of Nvim.
Existing "inspect" functions:
vim.inspect()
vim.inspect_pos()
vim.treesitter.inspect_language()
nvim__inspect_cell
Solution:
Rename `show_tree` to `inspect_tree`.
This function replaces both vim.treesitter.get_node_at_pos() and
vim.treesitter.get_node_at_cursor(). These two functions are similar
enough that they don't need separate interfaces. Even worse,
get_node_at_pos() returns a TSNode while get_node_at_cursor() returns a
string, so the two functions behave slightly differently.
vim.treesitter.get_node() combines these two into a more streamlined
interface. With no arguments, it returns the node under the cursor in
the current buffer. Optionally, it can accept a buffer number or a
position to get the node at a given position in a given buffer.
Problem:
vim.treesitter does not know how to map a specific filetype to a parser.
This creates problems since in a few places (including in vim.treesitter itself), the filetype is incorrectly used in place of lang.
Solution:
Add an API to enable this:
- Add vim.treesitter.language.add() as a replacement for vim.treesitter.language.require_language().
- Optional arguments are now passed via an opts table.
- Also takes a filetype (or list of filetypes) so we can keep track of what filetypes are associated with which langs.
- Deprecated vim.treesitter.language.require_language().
- Add vim.treesitter.language.get_lang() which returns the associated lang for a given filetype.
- Add vim.treesitter.language.register() to associate filetypes to a lang without loading the parser.
- Render node ranges as virtual text
- Set filettype=query. The virtual text is to avoid parsing errors.
- Make sure highlights text is always in view.
Add a "show_tree" function to view a textual representation of the
nodes in a language tree in a window. Moving the cursor in the
window highlights the corresponding text in the source buffer, and
moving the cursor in the source buffer highlights the corresponding
nodes in the window.
fix(treesitter): get_captures_at_position returns metadata
Return the full `metadata` table for the capture instead of just the
priority.
Further cleanup of related docs.
