feat(lua): add vim.system()
Problem:
Handling system commands in Lua is tedious and error-prone:
- vim.fn.jobstart() is vimscript and comes with all limitations attached to typval.
- vim.loop.spawn is too low level
Solution:
Add vim.system().
Partly inspired by Python's subprocess module
Does not expose any libuv objects.
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:
Selecting a search result from the Algolia Docsearch widget does not
navigate to a page anchor. The docs HTML provides `<a name=…>` anchors
_near_ the `<h1>`/`<h2>`/… headings, but Algolia Docsearch expects the
anchors to be _defined on_ the headings. That's also "semantically"
nicer. https://docsearch.algolia.com/docs/manage-your-crawls/
Solution:
Set `id` on the heading element instead of placing `<a name=…>` nearby.

The cmake.deps build will read this file and set the left part of the
text as the variable name and the right part as the variable value. The
benefit of doing this is that it becomes much easier to parse which
dependencies are required, as well as to bump dependencies with
scripts/bump_deps.lua.
Adjust bump_deps.lua script to work with this new format.
This one generates a runtime/ file instead of a source file.
But otherwise it works the same like all other generators.
It has the same prerequisites (shared and mpack modules, etc), and,
importantly, it uses results from the source generators.
The odd location makes it easy to overlook when refactoring generators
(like I did last time, lol)
vim.iter wraps a table or iterator function into an `Iter` object with
methods such as `filter`, `map`, and `fold` which can be chained to
produce iterator pipelines that do not create new tables at each step.
* feat(lua): vim.tbl_contains supports general tables and predicates
Problem: `vim.tbl_contains` only works for list-like tables (integer
keys without gaps) and primitive values (in particular, not for nested
tables).
Solution: Rename `vim.tbl_contains` to `vim.list_contains` and add new
`vim.tbl_contains` that works for general tables and optionally allows
`value` to be a predicate function that is checked for every key.
- version.cmp(): assert valid version
- add test for loading vim.version (the other tests use shared.lua in
the test runner)
- reduce test scopes, reword test descriptions
Problem:
gen_vimdoc.py / lua2dox.lua does not support @defgroup or \defgroup
except for "api-foo" modules.
Solution:
Modify `gen_vimdoc.py` to look for section names based on `helptag_fmt`.
TODO:
- Support @module ?

Problem:
Help tags like vim.treesitter.language.add() are confusing because
`vim.treesitter.language` is (thankfully) not a user-facing module.
Solution:
Ignore the "fstem" when generating "treesitter" tags.
https://github.com/neovim/neovim/pull/22398 broke the job because there
is no `build/bin/nvim`
This keeps the preference for `build/bin/nvim` but adds back `nvim` as
fallback if it doesn't exist.
Problem:
Treesitter injections are slow because all injected trees are invalidated on every change.
Solution:
Implement smarter invalidation to avoid reparsing injected regions.
- In on_bytes, try and update self._regions as best we can. This PR just offsets any regions after the change.
- Add valid flags for each region in self._regions.
- Call on_bytes recursively for all children.
- We still need to run the query every time for the top level tree. I don't know how to avoid this. However, if the new injection ranges don't change, then we re-use the old trees and avoid reparsing children.
This should result in roughly a 2-3x reduction in tree parsing when the comment injections are enabled.
Having to specify CI_BUILD for every CI job requires boilerplate. More
importantly, it's easy to forget to enable CI_BUILD, as seen by
8a20f9f98a. It's simpler to remember to
turn CI_BUILD off when a job errors instead of remembering that every
new job should have CI_BUILD on.
- Suggest reading CONTRIBUTING.md once, not for each commit failure
- Suggest using "fix" type if none of the provided types are appropriate
- Remove "dist" type. It's rarely used and can be replaced by using the
"build" type
When I run ./scripts/bump_deps.lua I get an error:
Vim:E475: Invalid value for argument cmd: 'command' is not executable
Running command -v in shell fixes this.
