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 ?
https://github.com/LuaLS/lua-language-server/wiki/Annotations#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.
Problem:
Build is not reproducible, because generated source files (.c/.h/) are not
deterministic, mostly because Lua pairs() is unordered by design (for security).

>> The hardening of the VM deliberately randomizes string hashes. This in

Solution:
- Update the code generation scripts to be deterministic.
- That is only a partial solution: the exported function
(funcs_metadata.generated.h) and ui event
(ui_events_metadata.generated.h) metadata have some mpack'ed
tables, which are not serialized deterministically.
- As a workaround, introduce `PRG_GEN_LUA` cmake setting, so you can
inject a modified build of luajit (with LUAJIT_SECURITY_PRN=0)
that preserves table order.
- Longer-term we should change the mpack'ed data structure so it no
longer uses tables keyed by strings.

Problem:
Nvim has Lua but the "nvim" CLI can't easily be used to execute Lua
scripts, especially scripts that take arguments or produce output.
Solution:
- support "nvim -l [args...]" for running scripts. closes#15749
- exit without +q
- remove lua2dox_filter
- remove Doxyfile. This wasn't used anyway, because the doxygen config
is inlined in gen_vimdoc.py (`Doxyfile` variable).
- use "nvim -l" in docs-gen CI job
Examples:
$ nvim -l scripts/lua2dox.lua --help
Lua2DoX (0.2 20130128)
...
$ echo "print(vim.inspect(_G.arg))" | nvim -l - --arg1 --arg2
$ echo 'print(vim.inspect(vim.api.nvim_buf_get_text(1,0,0,-1,-1,{})))' | nvim +"put ='text'" -l -
TODO?
-e executes Lua code
-l loads a module
-i enters REPL _after running the other arguments_.
Use `white-space: pre-wrap` to preserve white space as per `pre`, but to
allow line wrapping if the display runs out of horizontal space.
This prevents lines overflowing their box, and causing horizontal
scrolling across the entire page on small screens.
This `pre-wrap` technique is used by GitHub to format code for mobile.
