This aligns its behaviour better with `nvim_win_close`.
Note that `:hide` is actually incapable of closing the cmdwin, unlike `:close`
and `:quit`, so this is a bit of a difference in behaviour.
Disallow closing the previous window from `nvim_win_close`, as this will cause
issues.
Again, no telling how safe this is. It also requires exposing old_curwin. :/
Also note that it's possible for the `&cmdheight` to change if, for example,
there are 2 tabpages and `nvim_win_close` is used to close the last window in
the other tabpage while `&stal` is 1. This is addressed in a later commit.
Problem: As discussed on Matrix, there was some interest in having
`nvim_open_win` again be able to open floats in the cmdwin (e.g: displaying a
hover doc related to what's in the cmdwin). After #23228, this was disallowed.
Solution: Allow `nvim_open_win` in the cmdwin as long as `!enter` and
`buffer != curbuf` (the former can cause all sorts of issues, and the latter
can crash Nvim after closing cmdwin). Also allow `nvim_win_set_buf` in a similar
fashion.
Note that we're not *entirely* sure if this is 100% safe (cmdwin is a
global-state-using-main-loop-calling beast), but this seems to work OK..?
Also:
- Check the buffer argument of `nvim_open_win` earlier, and abort if it's
invalid (it used to still open a window in this case).
- Untranslate `e_cmdwin` errors in the API (other errors in the API are not
translated: although not detailed in the API contract yet, errors are
supposed to be stable).
Problem:
nvim_parse_cmd() in pcall() may show an error message (side-effect):
:lua pcall(vim.api.nvim_parse_cmd, vim.fn.getcmdline(), {})
E16: Invalid range
Solution:
Avoid emsg() in the nvim_parse_cmd() codepath.
- refactor(api): add error message output parameter to get_address()
- fix: null check emsg() parameter
- refactor: remove emsg_off workaround from do_incsearch_highlighting()
- refactor: remove emsg_off workaround from cmdpreview_may_show()
- refactor: remove remaining calls to emsg() from parse_cmd_address() and get_address()
- (refactor): lint set_cmd_dflall_range()
- refactor: addr_error() - move output parameter to return value
Fix#20339
TODO:
These are the functions called by `get_address()`:
```
nvim_parse_cmd() -> parse_cmdline() -> parse_cmd_address() -> get_address()
skipwhite()
addr_error()
qf_get_cur_idx()
qf_get_cur_valid_idx()
qf_get_size()
qf_get_valid_size()
mark_get()
mark_check()
assert()
skip_regexp()
magic_isset()
> do_search()
> searchit()
ascii_isdigit()
getdigits()
getdigits_int32()
compute_buffer_local_count()
hasFolding()
```
From these functions, I found at least two that call emsg directly:
- do_search()
- seems to be simple to refactor
- searchit()
- will be more challenging because it may generate multiple error messages,
which can't be handled by the current `errormsg` out-parameter.
For example, it makes multiple calls to `vim_regexec_multi()` in a loop that
possibly generate error messages, and later `searchit()` itself may generate
another one:
- c194acbfc4/src/nvim/search.c (L631-L647)
- c194acbfc4/src/nvim/search.c (L939-L954)

Problem:
`:lua vim.cmd.win_getid(30,10)` is interpreted as `:win[size] 30 10`.
User intention was to call `vim.fn.win_getid(30,10)`.
Solution:
Check that the `cmd` actually matches the resolved command.
Problem:
Nvim version string typically has a "build" component
but vim.version() doesn't report it.
Solution:
Add the "build" field to vim.version().
Closes#23863
The options 'path', 'include', and 'define' all use C-specific default
values. This may have made sense a long time ago when Vim was mostly
used just for writing C, but this is no longer the case, and we have
ample support for filetype specific configuration. Make the default
values of these options empty and move the C-specific values into a
filetype plugin where they belong.

`nvim_(get|set)_option_value` pick the current buffer / window by default for buffer-local/window-local (but not global-local) options. So specifying `buf = 0` or `win = 0` in opts is unnecessary for those options. This PR removes those to reduce code clutter.
Having the user set `v:lnum` before calling `nvim_eval_statusline()` is
unnecesarily fragile. Redraws inbetween setting `v:lnum` and the
`nvim_eval_statusline()` call will overwrite `v:lnum`.
Problem: Can not get all extmarks in a buffer. Properties are missing
from the details array.
Solution: Allow getting all extmarks in a buffer by supplying a -1
"ns_id". Add missing properties to the details array.
Problem: No way to get the actual highlight attributes for a linked
group through |nvim_get_hl()| (not the attributes from the link target).
Solution: Return the actual attributes as well as the link target name.
fix(api): use local LastSet structure in nvim_get_option_info
* nvim_get_option_info is deprecated.
It is always using the global LastSet information as reported in #15232.
* nvim_get_option_info2 is added.
The new function additionally accepts an 'opts' table {scope, buf, win}
allowing to specify the option scope and query local options from another
buffer or window.
Problem: no way of getting all highlight group definitions in a namespace.
Solution: add `nvim_get_hl()`, deprecate `nvim_get_hl_by_name()` and `nvim_get_hl_by_id()`.
