Problem: Timer removing a message from the msg buffer does not remove
empty lines if window is closed (col([ui.wins.msg]) fails).
Solution: Use nvim_buf_get_text() to check if line is empty.
The wait added in #37853 doesn't seem to do anything as request is sent
immediately on InsertLeave, and the number 4 also seems wrong. Instead,
the actual cause for the flakiness that the feed() (and hence the buffer
change) may arrive before the scheduled initialization of capabilities,
causing there be only only one textDocument/semanticTokens/full request
instead of two.
Problem:
- `:args` and `argv()` can change after startup.
- `v:arg` includes options/commands, not just files.
- Plugins (e.g. Oil) may rewrite directory args.
Solution:
- New read-only var `v:argf`: snapshot of file/dir args at startup.
- Unaffected by `:args` or plugins.
- Unlike `v:argv`, excludes options/commands.
- Paths are resolved to absolute paths when possible
Example:
nvim file1.txt dir1 file2.txt
:echo v:argf
" ['/home/user/project/file1.txt', '/home/user/project/dir1', '/home/user/project/file2.txt']
Problem: - Unintentionally inserting lines for a replaced multiline
message that also has multiple highlights.
- Scheduled check to see if the expanded cmdline window was
entered makes it difficult to keep track of what happens when
the key pressed to dismiss it results in a message.
- Reading the first line of an error message should be enough
notice for something going wrong.
- "search_cmd" messages should not be shown with 0 'cmdheight'.
- Unable to configure dynamically changed pager height.
- Enabling UI2 doesn't make sense with no UIs attached.
Solution: - Only insert a line for the first chunk after a newline.
- Use getmousepos() to check if the expanded cmdline was
clicked to enter the pager.
entering the pager to serve as a configuration interface.
- Don't expand the cmdline for error messages; user can press g<.
- Don't show "search_cmd" messages with 'cmdheight' set to 0.
- Change 'eventignorewin' to ensure WinEnter is fired when
- Have enable() return early when no UIs are attached.
Problem:
:InspectTree don't show luadoc injection lua file. Since luadoc share
the same "root" with comment in their common primary (lua) tree.
Current logic simply show the largest (comment injection) and ignore all
smaller one (luadoc injection).
Solution:
Handle different lang injections separately. Then sort them by
byte_length to ensure the draw tree consistent.
Problem: Newlines emitted with ext_messages intended to position
the message/prompt on the message grid.
Solution: Don't emit these newlines with ext_messages, followup to 4260f73e.
Problem: after #33036, an error from evaluating 'statusline' clears it and
doesn't draw the statusline. (causing glitchy redraws)
Solution: use the default value instead. If 'stl' is somehow ever empty, still
call redraw_custom_statusline to at least draw an empty statusline.
Ideally our default 'stl' shouldn't itself error too! :-)
Also adjust some prior screen:expect()s to avoid immediate success warnings.
When using feed_data() with hidden buffer, terminal refresh may arrive
during may_restore_curbuf(), causing "last cursor" positions to change.
Get the two "last cursor" positions in the same RPC call.
If the last nvim_eval arrives on RPC channel before rpc_close_event() is
processed, it will be scheduled immediately after rpc_close_event() and
before free_channel_event(), causing the test to fail.
Adding input doesn't help here, as the important part here is processing
main_loop.events, not running the main loop. Instead, use a non-fast API
request to ensure that previously queued events are processed.
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.
This is a better way to prevent parallel tests from interfering with
each other, as there are many ways files can be created and deleted in
tests, so enforcing different file names is hard.
Using $TMPDIR can also work in most cases, but 'backipskip' etc. have
special defaults for $TMPDIR.
Symlink runtime/, src/, test/ and README.md to Xtest_xdg dir to make
tests more convenient (and symlinking test/ is required for busted).
Also, use README.md instead of test/README.md in the Ex mode inccommand
test, as test/README.md no longer contains 'N' char.
Problem: UIs put ins-completion "scanning" messages one after another,
which are meant to overwrite the previous message.
Solution: Ensure the msg_show "replace_last" parameter is set.
Problem: Fake LSP server does not timeout or respond to SIGTERM as it
does not run the event loop.
Solution: Instead of io.read(), use stdioopen()'s on_stdin callback to
accumulate input and use vim.wait() to wait for input.
Also, in the test suite, don't stop a session when it's not running, as
calling uv.stop() outside uv.run() will instead cause the next uv.run()
to stop immediately, which cancels the next RPC request.
- Rename ".nvimlog" to "nvim.log"
- doesn't need to be "hidden"/dotfile
- ".log" extension helps with filetype detection
- Also rename "nvim/log" => "nvim/nvim.log"
Define a CMake target for every subdirectory of test/functional that
contains functional tests, and a functionaltest_parallel target that
depends on all those targets, allowing multiple test runners to run in
parallel.
On CI, use at most 2 parallel test runners, as using more may increase
system load and make tests unstable.
Problem: undoing after the prompt is changed breaks it (and causes init_prompt
to abort it and append a new one), as the undo history contains the old prompt.
Solution: like submitting, clear the undo buffer. Don't do it in init_prompt if
the line was empty; that may not result in a new prompt, and causes commands
like "S" to lose the history.
As u_save, etc. wasn't being called by prompt_setprompt, undoing after it fixes
the prompt usually gave undesirable results anyway.
Remove the added undo_spec.lua test, as its approach no longer works as a repro,
and finding a new one seems fiddly.
Problem: prompt_setprompt adjusted cursor col may be negative (<=0 when
1-based), and doesn't check the col of ':
Solution: avoid negative col and adjust correctly if ': col differs from old
prompt's length.
Problem: Implicitly setting message target when 'cmdheight' changes.
Solution: Just use the user configured target. Support "cmd" target
with 'cmdheight' set to 0.
Problem:
When MsgArea highlight is changed, the next message may flash
and disappear because msg_start() renders with stale highlight attributes.
msg_puts_len() uses HL_ATTR(HLF_MSG) to render message text, which
happens before update_screen() calls highlight_changed().
So the message is rendered with outdated attrs.
Solution:
Call highlight_changed() in msg_start().
Problem: Opening a terminal on an empty buffer produces a spurious
buffer update event.
Solution: Don't call deleted_lines_buf() if no lines have been deleted.
Problem: Paging keys being consumed without obvious indicator
in the dialog window can be surprising.
Solution: Display a hint with paging keys in the dialog window title
when paging is active. Recognize <Esc> as mapping to stop
paging.
Problem: prompt_setprompt memory leak/other issues when fixing prompt line for
unloaded buffer, or when ': line number is zero.
Solution: don't fix prompt line for unloaded buffer. Clamp ': lnum above zero.
Problem: vim.on_key() called for each message while cmdline is open.
Cursor is on a seemingly random column when pager is entered.
Entering the pager while the cmdline is expanded can be more
convenient than pressing "g<".
Pager window is unnecessarily clamped to half the shell height.
Setting 'laststatus' while pager is open does not adjust its
dimensions.
Solution: Only call vim.on_key() once when dialog window is opened.
Ensure cursor is at the start of the first message when
entering the pager.
Enter the pager window when "<CR>" is pressed while the
cmdline is expanded.
Don't clamp the pager window height.
Set message windows dimensions when 'laststatus' changes.
Problem: Logic determining messages belonging to the last command to
show with "g<" does not flush pending messages. This can
result in clearing the temporary message history before a
message still belonging to the previous command was emitted.
Solution: Flush pending messages when marking the end of messages
belonging to previous command.
