Problem:
`excmd_get_argt` and `get_cmd_argt` do the same thing.
Solution:
Drop `get_cmd_argt` and update its callers to use `excmd_get_argt`.
(cherry picked from commit 1fd82615b1)
Problem:
Invalid `nvim_create_user_command` calls can leak the
`preview` callback reference after Neovim has taken ownership of it.
1. build with {a,l}san
2. run:
```sh
<path/to/nvim> --headless -u NONE --clean +'lua
for i = 1, 100 do
pcall(vim.api.nvim_create_user_command,
"some very epic stuff" .. i,
{}, -- NOTE: this is INVALID (not a function or string)
{ preview = function() end })
end
vim.cmd("qa!")
' +qa
```
3. see:
```
100 lua references were leaked!
```
Solution:
Clear `preview_luaref` in `err:`.

test: lint naming conventions
Problem:
Naming conventions are not automatically checked.
Solution:
Add a check to the doc generator. Eventually we should extract this
somehow, but that will require refactoring the doc generator...
Note: this also checks non-public functions, basically anything that
passes through `gen_eval_files.lua` and `gen_vimdoc.lua`. And that's
a good thing.
In 3a4a66017b, 4d3a67cd62, df8d98173c we renamed "buffer" to "buf"
in dict parameters and return-values.
This commit renames positional parameters. This is only "cosmetic", but
is intended to make it extra clear which name is preferred, since people
often copy existing code despite the guidelines in `:help dev-naming`.
(cherry picked from commit d0af4cd909)
Problem: nvim_parse_cmd rejects valid commands like `:1` (range-only)
or `aboveleft` (modifier-only).
Solution: allow empty command when range or modifiers exist, and handle
execution using existing range command logic.
Problem: The ops.c file is too big.
Solution: Move code for dealing with registers to a new file. (Yegappan

These are not needed after #35129 but making uncrustify still play nice
with them was a bit tricky.
Unfortunately `uncrustify --update-config-with-doc` breaks strings
with backslashes. This issue has been reported upstream,
and in the meanwhile auto-update on every single run has been disabled.
Problem: parse_cmdline() sets eap->cmdlinep to address of local parameter,
causing invalid memory access when expand_filename() tries to modify it.
This leads to crashes when typing '%' in user commands with preview=true
and complete=file.
Solution: Change parse_cmdline() signature to accept char **cmdline,
allowing cmdlinep to point to caller's variable for safe reallocation.
Problem: Using `addr` without `range` in nvim_create_user_command gives
"No range allowed" error, inconsistent with `:command -addr` behavior.
Solution: Set EX_RANGE flag when `addr` option is specified to match
`:command` behavior.
- Render Lua types in api.txt.
- Added `DictAs(name)` API type which acts the same as `Dict` (no parens)
when generating the dispatchers, but acts the same as `Dict(name)`
when generating docs.
- Added `Tuple(...)` API type which is the treated the as `Array` for
generating the dispatchers, but is used to document richer types.
- Added `Enum(...)` API type to better document enums
- Improve typing of some API functions.
- Improve c_grammar to properly parse API types and replace string pattern
logic in the parsers.
- Removed all the hardcoded type overrides in gen_eval_files.lua
Problem: nvim_parse_cmd() incorrectly splits mapping commands like
into three arguments instead of preserving whitespace in the RHS.
Solution: Add special handling for mapping commands to parse them as exactly
two arguments - the LHS and the RHS with all whitespace preserved.
Problem:
- nvim_parse_cmd('copen', {}) returns count: 0, causing nvim_cmd to override default behavior
- nvim_cmd({cmd = 'copen', args = {10}}, {}) fails with "Wrong number of arguments"
Solution:
- Only include count field in parse result when explicitly provided or non-zero
- Interpret single numeric argument as count for count-only commands like copen
Problem:
nvim_parse_cmd returns invalid 'range' field for cmd like `:bdelete`.
Solution:
Add the condtion `ea.add_count > 0` as required to put 'range'
into result.

In the api_info() output:
:new|put =map(filter(api_info().functions, '!has_key(v:val,''deprecated_since'')'), 'v:val')
...
{'return_type': 'ArrayOf(Integer, 2)', 'name': 'nvim_win_get_position', 'method': v:true, 'parameters': [['Window', 'window']], 'since': 1}
The `ArrayOf(Integer, 2)` return type didn't break clients when we added
it, which is evidence that clients don't use the `return_type` field,
thus renaming Dictionary => Dict in api_info() is not (in practice)
a breaking change.
This also makes shada reading slightly faster due to avoiding
some copying and allocation.
Use keysets to drive decoding of msgpack maps for shada entries.
Problem:
The documentation flow (`gen_vimdoc.py`) has several issues:
- it's not very versatile
- depends on doxygen
- doesn't work well with Lua code as it requires an awkward filter script to convert it into pseudo-C.
- The intermediate XML files and filters makes it too much like a rube goldberg machine.
Solution:
Re-implement the flow using Lua, LPEG and treesitter.
- `gen_vimdoc.py` is now replaced with `gen_vimdoc.lua` and replicates a portion of the logic.
- `lua2dox.lua` is gone!
- No more XML files.
- Doxygen is now longer used and instead we now use:
- LPEG for comment parsing (see `scripts/luacats_grammar.lua` and `scripts/cdoc_grammar.lua`).
- LPEG for C parsing (see `scripts/cdoc_parser.lua`)
- Lua patterns for Lua parsing (see `scripts/luacats_parser.lua`).
- Treesitter for Markdown parsing (see `scripts/text_utils.lua`).
- The generated `runtime/doc/*.mpack` files have been removed.
- `scripts/gen_eval_files.lua` now instead uses `scripts/cdoc_parser.lua` directly.
- Text wrapping is implemented in `scripts/text_utils.lua` and appears to produce more consistent results (the main contributer to the diff of this change).
Note: this contains two _temporary_ changes which can be reverted
once the Arena vs no-Arena distinction in API wrappers has been removed.
Both nlua_push_Object and object_to_vim_take_luaref() has been changed
to take the object argument as a pointer. This is not going to be
necessary once these are only used with arena (or not at all) allocated
Objects.
The object_to_vim() variant which leaves luaref untouched might need to
stay for a little longer.
and for return value of nlua_exec/nlua_call_ref, as this uses
the same family of functions.
NB: the handling of luaref:s is a bit of a mess.
add api_luarefs_free_XX functions as a stop-gap as refactoring
luarefs is a can of worms for another PR:s.
as a minor feature/bug-fix, nvim_buf_call and nvim_win_call now preserves
arbitrary return values.
Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
