Problem: Now way to show text at the bottom part of floating window
border (a.k.a. "footer").
Solution: Allows `footer` and `footer_pos` config fields similar to
`title` and `title_pos`.
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.
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:
Lua functions that return multiple results are declared by using
multiple `@return` docstring directives. But the generated docs don't
make it obvious what this represents.
Solution:
- Generate a "Return (multiple)" heading for multiple-value functions.
- Fix `@note` directives randomly placed after `@return`.
Problem: nvim_buf_set_text(), nvim_open_term() and termopen() all change buffer
text, which is forbidden during textlock. Additionally, nvim_open_term() and
termopen() may be used to convert the cmdwin buffer into a terminal buffer,
which is weird.
Solution: Allow nvim_buf_set_text() and nvim_open_term() in the cmdwin, but
disallow nvim_open_term() from converting the cmdwin buffer into a terminal
buffer. termopen() is not allowed in the cmdwin (as it always operates on
curbuf), so just check text_locked().
Also happens to improve the error in #21055: nvim_buf_set_text() was callable
during textlock, but happened to check textlock indirectly via u_save();
however, this caused the error to be overwritten by an unhelpful "Failed to
save undo information" message when msg_list == NULL (e.g: an `<expr>` mapping
invoked outside of do_cmdline()).
Problem: some API functions that check textlock (usually those that can change
curwin or curbuf) can break the cmdwin.
Solution: make FUNC_API_CHECK_TEXTLOCK call text_locked() instead, which already
checks for textlock, cmdwin and `<expr>` status.
Add FUNC_API_TEXTLOCK_ALLOW_CMDWIN to allow such functions to be usable in the
cmdwin if they can work properly there; the opt-in nature of this attribute
should hopefully help mitigate future bugs.
Also fix a regression in #22634 that made functions checking textlock usable in
`<expr>` mappings, and rename FUNC_API_CHECK_TEXTLOCK to FUNC_API_TEXTLOCK.
Problem: vimdoc parser requires space between column heading and `~`.
Solution: Add space to docs (and mention it). Also edit `luaref.txt`
headings for consistency.
Problem:
In the generated docs HTML there is too much whitespace before/after `<pre>`
blocks.
- In the old layout (fixed-width), all text in `.old-help-para` is formatted as
`white-space:pre`.
- In the new layout, when `<pre>` is at the end of a `<div>`, the margins of
both are redundant, causing too much space.
Solution:
- In the old layout, always remove `<pre>` margin.
- In the new layout, disable `<pre>` margin if it is the last child.
Enforce consistent terminology (defined in
`gen_help_html.lua:spell_dict`) for common misspellings.
This does not spellcheck English in general (perhaps a future TODO,
though it may be noisy).

- docs: mention --luadev-mod to run with lua runtime files
When changing a lua file in the ./runtime folder, a new contributor
might expect changes to be applied to the built Neovim binary.
fix(extmarks): disallow removing extmarks in on_lines callbacks
decor_redraw_start (which runs before decor_providers_invoke_lines) gets
references for the extmarks on a specific line. If these extmarks are
deleted in on_lines callbacks then this results in a heap-use-after-free
error.
Fixes#22801
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:
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: 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()`.
