Problem: possible to configure a split as a floatwin with relative=win that is
relative to itself.
Solution: fix the check.
Not caused by this PR; just something I noticed when about to fix the validation
logic.
Problem: when nvim_win_set_config moves a floatwin between tabpages, its grid
may remain if temporarily inside another tabpage. Also, things like tablines
aren't redrawn.
Solution: always remove its grid. Set must_redraw so things are redrawn even if
w_redr_type was already set for the old tabpage.
I don't think it's necessary to do anything extra here when removing the grid:
- win_ui_flush calls ui_call_win_hide anyway, and calling it manually ends up
sending two win_hide events.
- ui_comp_remove_grid safely does nothing if the grid doesn't exist.
- w_pos_changed is set by win_config_float later, if that's needed. I think the
pending_comp_index_update set by ui_comp_remove_grid is enough anyway, at
least for making sure win_ui_flush sends win_hide.
Added test fails with the prior approach of checking `parent_tp != curtab`, but
also `win_tp == curtab`. (which is a better, but still flawed alternative)
The added redrawing here also supersedes setting w_hl_needs_update, and also
redraws stuff like the tabline to pass the new test.
- Factor out logic to keep nvim_win_set_config clean.
- Clean up a few things, remove redundant logic, reflow some lines.
- Add some more comments where appropriate.
- Don't consider negative "win", as that's only relevant for splits.
- Add more test coverage.
- Add news.txt entry.
Problem: nvim_win_set_config can't move floating windows to different tab pages.
Solution: allow it.

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:
When a terminal process exits, "[Process Exited]" text is added
to the buffer contents.
Solution:
- Return `exitcode` field from `nvim_get_chan_info`.
- Show it in the default 'statusline'.
- Show exitcode as virtual text in the terminal buffer.
Problem:
There is an inconsistency between extmarks/highlights regarding the
`end_col` param.
Solution:
Allow end_col=-1 to mean "end of line" (if strict=false).

Problem: nvim_win_set_config may raise unnecessary errors when not moving a
split.
Solution: skip checks related to moving when only maybe resizing a split.
Problem: No explicit redraw after setting style=minimal in nvim_open_win or
nvim_win_set_config, which may cause it to appear like it's not set.
Solution: call changed_window_setting after applying the style, which should be
enough for these options.
Problem: nvim_win_set_config may merge configs despite failing to configure a
split, and without applying necessary side-effects (like setting style=minimal
options). Plus, autocommands may apply a different config after the merge,
causing side-effects to apply for an outdated config.
Solution: merge configs last, only on success. Include fields only relevant to
splits. Properly set _cmdline_offset for splits.
Maybe better to disallow _cmdline_offset for splits instead, as the pum is
relative to cmdline_row anyway? (I didn't want to change behaviour too much)
Also use expect_unchanged in an unrelated test to quash a warning.
Problem: nvim_win_set_config with style="minimal" does not take immediate effect
when a split is not moved.
Solution: don't skip nvim_win_set_config's epilogue when only a resize may be
needed. De-duplicate resize logic and remove unnecessary redraw. (win_set*_win
already handles that)
Problem: Calling nvim_set_hl() with url= crashes because it tries to
free arena-owned string memory.
Solution: Remove the bad free and return a validation error instead.
using the GNU compiler we just get a bunch of const warnings we can fix.
clang, however, gets really upset that the standard library suddenly
starts using a lot of c11 features, despite us being in -std=gnu99 mode.
Basically, _GNU_SOURCE which we set is taken as a _carte blanche_ by the
glibc headers to do whatever they please, and thus we must inform clang
that everything is still OK.
Problem: Unable to tell whether a msg_show event is emitted as a result
a command typed on the cmdline (UI may want to represent these
differently from other messages).
Solution: Add trigger parameter that is set to "typed_cmd" for
a message emitted due to an interactively typed command.
Possible extensions are mapping/timer/event but it's hard to
imagine a UI distinguishing those so not added here.
Problem: nvim_win_get_config() does not return a window's "style".
Solution: always include it, and document `style=""`.
Always included so it can be used reciprocally with nvim_open_win() or
nvim_win_set_config(). (otherwise the config of a window with kWinStyleUnused
will not unset the kWinStyleMinimal style of another window if passed to
nvim_win_set_config, for example)
Problem:
TUI does not support several standard SGR text attributes:
- dim/faint (SGR 2)
- blink (SGR 5)
- conceal (SGR 8)
- overline (SGR 53)
This means that when a program running in the embedded terminal emits
one of these escape codes, we drop it and don't surface it to the
outer terminal.
Solution:
- Add support for those attributes.
- Also add corresponding flags to `nvim_set_hl` opts, so users can set
these attributes in highlight groups.
- refactor(highlight): widen `HlAttrFlags` from `int16_t` to `int32_t`
Widen the `rgb_ae_attr` and `cterm_ae_attr` fields in HlAttrs from
int16_t to int32_t to make room for new highlight attribute flags,
since there was only one spare bit left.
- The C flag is named HL_CONCEALED to avoid colliding with the
existing HL_CONCEAL in syntax.h (which is a syntax group flag, not
an SGR attribute).
- Also note that libvterm doesn't currently support the dim and overline
attributes, so e.g. `printf '\e[2mThis should be dim\n'` and `printf
'\e[53mThis should have an overline\n'` are still not rendered
correctly when run from the embedded terminal.
Problem: Strange behavior when opening terminal on unloaded buffer.
Solution: For nvim_open_term() ensure the buffer is loaded as it needs
to be read into the terminal. For jobstart() just open the
memfile as the file content isn't needed.
Not going to make nvim_open_term() pass stdin to the terminal when stdin
isn't read into a buffer yet, as other APIs don't read stdin on unloaded
buffer either. There are also other problems with loading buffer before
reading stdin, so it's better to address those in another PR.
Problem: Setting 'winhighlight' doesn't after setting global namespace
using nvim_win_set_hl_ns().
Solution: Check if using another namespace when setting 'winhighlight'
instead of disabling 'winhighlight' in nvim_win_set_hl_ns().
Problem:
- `:restart <cmd>` prepends `-c <cmd>` before the original `-c` args (if
any). So the original `-c` args may "override" it, which is
surprising.
- Confusing logic: `v:argv` is partially prepared in `ex_docmd.c`, and
then later `ui.c` skips other parts of it.
Current behavior is nonsense, for example this sequence:
:restart echo "Hello"
:restart +qall echo "Hello" | echo "World"
results in this v:argv:
[
'nvim'
'-c'
'echo "Hello" | echo "World"'
'--embed'
'-c'
'echo "Hello"'
...
]
Whereas after this commit, v:argv is:
[
'nvim'
'--embed'
...
'-c'
'echo "Hello" | echo "World"'
]
Solution:
- Append `-c <cmd>` at the _end_ of `v:argv`, not the start.
- Use a dummy placeholder `+:::` to mark where the "restart command"
appears in `v:argv`.
- Do all `v:argv` preparation in `ex_docmd.c`. This simplifies `ui.c`.
- Drop `-- [files…]` from `v:argv` since it is probably more annoying
than useful. (Users can use sessions to restore files on restart.)
Problem: Terminal doesn't detect if the PTY process is suspended or
offer a convenient way for the user to resume the process.
Solution: Detect suspended PTY process on SIGCHLD and show virtual text
"[Process suspended]" at the bottom-left. Resume the process
when the user presses a key.
Problem: cterm field in Dict(highlight) is declared as Union(Integer, String)
but it actually expects a Dict(highlight_cterm).
Solution: change cterm type to DictAs(highlight__cterm) and simplify the
handling in dict2hlattrs since type validation and empty array compat are
already handled by api_dict_to_keydict.
Problem: TermResponse deferred due to blocked autocommands lacks "data" payload.
Also, it may not fire if a new v:termresponse reuses the same string address.
Solution: add it. Use the value of v:termresponse for "data.sequence". Replace
pointer comparisons with a flag.
The removal of "old_termresponse" comparisons is required to pass the test on
the CI, or locally for me when compiled in RelWithDebInfo.
Problem: Terminal loses output if a BufFilePre or BufFilePost autocmd
polls for events.
Solution: Rename the buffer after allocating the terminal instance. Also
fix buffer getting wrong name if BufFilePre uses NameBuff.
Problem: Fast context for msg_show event inhibits vim.ui_attach from
displaying a stream of messages from a single command.
Solution: Remove fast context from msg_show events emitted as a result
of explicit API/command calls. The fast context was originally
introduced to prevent issues with internal messages.
fix(api): auto-load buffers in nvim_buf_set_* operations
Problem: Setting marks, lines, or text on unloaded buffers fails because
ml_line_count is not accurate until the buffer is loaded.
Solution: Add require_loaded_buffer() helper and use it in write operations
(nvim_buf_set_lines, nvim_buf_set_text, nvim_buf_set_mark). These now
auto-load buffers as needed.
Problem: nvim_get_option_value with "filetype" set can crash if autocommands
open the dummy buffer in more windows, or if &bufhidden == "wipe".
Solution: Attempt to close all dummy buffer windows before wiping. Promote the
dummy buffer to a normal buffer if that fails.
Problem: When the "filetype" key is set for nvim_get_option_value, autocommands
can crash Nvim by prematurely wiping the dummy buffer, or cause options intended
for it to instead be set for unrelated buffers if switched during OptionSet.
Solution: Don't crash. Also quash side-effects from setting the buffer options.
Problem:
Using nvim_set_current_win() to switch windows while in Visual mode
causes E315 ml_get error when target buffer has fewer lines. This
doesn't happen with `:wincmd w` since it properly resets Visual mode
when switching buffers.
Solution:
Reset Visual mode when switching to another buffer, like `:wincmd w`.
Problem: Calling termopen() or nvim_open_term() on a buffer with an
existing terminal leads to two terminals writing to the same
buffer if the terminal job is still running, or memory leak
if the terminal job has exited.
Solution: Close the terminal if the terminal job has exited, otherwise
report an error. For nvim_open_term() also don't write a
closed terminal's buffer content to the PTY.
Problem: error set by win_set_buf may leak if autocommands immediately close the
new window.
Solution: free the error set by win_set_buf. (prefer nvim_open_win's error as
it's more important and will cause 0 to be returned)
Problem: split_disallowed seemingly exists to prevent issues from changing
frames to accomodate a split window, which doesn't apply to floats.
Solution: remove the restriction for nvim_open_win, but only for floats.
(continue to check b_locked_split though)
NOTE: like before, the buffer we check b_locked_split for may not actually be
the target buffer "buf", as the later call to win_set_buf can fail to switch to
"buf" due to autocommands. (among other things)
Maybe we could attempt to close the new window in that case (or switch to a
different buffer if that also fails), but this is safer. (and simpler)
Fixes#36857 (and possibly some spurious E242s I've observed from extui)
Problem: Converting a funcref to a string leaves out "g:", causing the
meaning of the name depending on the context.
Solution: Prepend "g:" for a global function.
