Problem:
On Windows, path separators may become inconsistent for various reasons,
which makes normalization quite painful.
Solution:
Normalize paths to `/` at the entry boundaries and always use it
internally, converting back only in rare cases where `\` is really
needed (e.g. cmd.exe/bat scripts?).
This is the first commit in a series of incremental steps.
Note:
* some funcs won't respect shellslash. e.g. `expand/fnamemodify`
* some funcs still respect shellslash, but will be updated in a follow
PR. e.g. `ex_pwd/f_chdir/f_getcwd`
* uv's built-in funcs always return `\`. e.g. `uv.cwd/uv.exepath`

In 3a4a66017b74192caaf9af9af172bdc08e0c1608, 4d3a67cd620152d11ab9b5f5bdd973f84cc2d44b
we renamed "buffer" to "buf" in dict parameters.
This commit also renames such keys in dict return-values.

Problem: Parsing :echo followed by invalid expression leads to error.
Solution: Suppress error when skipping over expression.
|
|
Problem:
`nvim_echo(…, {id=…})` accepts user-defined id as a string or integer.
Generated ids are always higher than last highest msg-id used. Thus
plugins may accidentally advance the integer id "address space", which,
at minimum, could lead to confusion when troubleshooting, or in the
worst case, could overflow or "exhaust" the id address space.
There's no use-case for it, and it could be the mildly confusing, so we
should just disallow it.
Solution:
Disallow *integer* user-defined message-id.
Only allow *string* user-defined message-id.
|
|
Problem:
nvim_get_option_value with "filetype" set silently returns incorrect
defaults if autocommands are blocked, like when they're already running.
Solution:
Allow its FileType autocommands to nest: `do_filetype_autocmd(force=true)`.
Also error if executing them fails, rather than silently return wrong defaults.
Endless nesting from misbehaving scripts should be prevented by the recursion
limit in apply_autocmds_group, which is 10.
|
|
|
|
Problem: nvim_echo()->kind memory may be used after it is freed with :messages.
Solution: Copy and free message kind string in message history.
|
|
|
|
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 stopping a PTY process on Windows, the exit code indicates that the
process is stopped by SIGTERM even when closing all streams is enough to
terminate the process. This is inconsistent with other platforms.
Solution:
Set exit_signal to SIGHUP instead of SIGTERM when using SIGHUP.
|
|
|
|
Problem:
Exit code in :terminal channel test depends on whether the shell or Nvim
TUI in the terminal has registered its SIGHUP handler when jobstop() is
called.
Solution:
Don't use a shell as shells on different systems may handle SIGHUP
differently. Add a screen:expect() to wait for the TUI to start.

#38131
Problem: Exception error message only prints the first chunk of a
multi-chunk nvim_echo() message.
Solution: Concatenate consecutive message chunks in the exception
message list.
|
|
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: Leading message newlines (not emitted with ext_messages since
4260f73) were responsible for resetting the redirection message
column (while the newline itself is later pruned...).
Solution: Ensure the redirection column is reset at the start of a message.
(Instead of re-adjusting all the newline callsites which can
themselves hopefully be pruned if ext_messages is enabled by
default.)
|
|
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: Message ID is not incremented without ext_messages.
Solution: Increment where callstack reaches without ext_messages.
There is no clear place marking the end of internal
messages without ext_messages so IDs are only incremented
with `nvim_echo` calls. Message IDs are currently not exposed
anywhere but the msg_show event for this to matter.
|
|
Problem: nvim_parse_expression null pointer dereference with unmatched ]
followed by a node.
Solution: if ast_stack was empty, set new_top_node_p to top of the stack after
pushing the list literal node; similar to what's done for curlies.
This bug was originally found by a Matrix user, but I couldn't remember how to
trigger it... Ran into the other crash while finding a repro. :P
|
|
Problem: nvim_parse_expression null pointer dereference when parsing an
identifier followed by { with "highlight" parameter set to false.
Solution: only set opening_hl_idx if pstate->colors is not NULL.
Not added to parser_tests.lua as that uses highlight = true.
|
|
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: nvim_parse_cmd('exe "ls"|edit foo', {}) fails to separate
nextcmd, returning args as { '"ls"|edit', 'foo' } instead of { '"ls"' }
with nextcmd='edit foo'.
Solution: Skip expressions before checking for '|' separator.
|
|
|
|
|
|
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: Since 48e2a736, prompt messages are handled by an actual
active cmdline, resulting in `State` no longer being equal
to `MODE_CONFIRM` which is used in some places. E.g. to
specify the current `mode()` or to re-emit a confirm message.
Solution: Replace `MODE_CONFIRM` with a new `MODE_CMDLINE` sub-mode when
`ccline.one_key/mouse_used` is set. Use it to avoid clearing
mouse_used prompt messages, and to re-emit one_key messages
(when ext_messages is inactive, for which this is unnecessary).
|
|
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__redraw may update the screen with an invalid topline.
Solution: Update the topline before calling `update_screen()` (as
:redraw does).
|
|
Problem:
nvim_cmd does not handle plus flags.
Solution:
In nvim_cmd, parse the flags and set the relevant `ea` fields.
|
|
"Error" in error messages is redundant. Just provide the context, don't
say "Error ...".

feat(build): build.zig MVP: build and run functionaltests on linux
|
|
NEW BUILD SYSTEM!
This is a MVP implementation which supports building the "nvim" binary,
including cross-compilation for some targets.
As an example, you can build a aarch64-macos binary from
an x86-64-linux-gnu host, or vice versa
Add CI target for build.zig currently for functionaltests on linux
x86_64 only
Follow up items:
- praxis for version and dependency bumping
- windows 💀
- full integration of libintl and gettext (or a desicion not to)
- update help and API metadata files
- installation into a $PREFIX
- more tests and linters

When nvim_open_term() is called with a non-empty buffer, the buffer
contents are piped into the PTY.
|
|
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.

Problem
Pasting a big string ("streamed paste" with multiple chunks) sets the '[
mark to the edit from the last chunk, instead of the start of the paste.
Solution:
Set the '[ mark where the paste started, not where the last chunk was
inserted.
Note: `startpos == nil` is not equal to `phase == 1` because there may
be some empty chunks pasted which won't arrive here (returned at code
before).

Problem: Sourcing buffer lines is too complicated.
Solution: Simplify the code. Make it possible to source Vim9 script lines.
(Yegappan Lakshmanan, closes vim/vim#9974)
https://github.com/vim/vim/commit/85b43c6cb7d56919e245622f4e42db6d8bee4194
This commit changes the behavior of sourcing buffer lines to always have
a script ID, although sourcing the same buffer always produces the same
script ID.
vim-patch:9.1.0372: Calling CLEAR_FIELD() on the same struct twice
Problem: Calling CLEAR_FIELD() on the same struct twice.
Solution: Remove the second CLEAR_FIELD(). Move the assignment of
cookie.sourceing_lnum (zeertzjq).
closes: vim/vim#14627

Problem: Combined highlighting was not applied to nvim_eval_statusline(),
and 'statuscolumn' sign segment/numhl highlights.
Solution: Add an additional `groups` element to the return value of
`nvim_eval_statusline()->highlights`. This is an array of stacked
highlight groups (highest priority last). Also resolve combined
highlights for the 'statuscolumn' sign segment/numhl highlights.
Expose/synchronize some drawline.c logic that is now mimicked in
three different places.

Problem:
The `nvim_notify` API (note: unrelated to `vim.notify()` Lua API) was
not given any real motivation in https://github.com/neovim/neovim/pull/13843
There are, and were, idiomatic and ergonomic alternatives already.
Solution:
Deprecate `nvim_notify`.
|
|
Problem: We want to deprecate `nvim_err_write(ln)()` but there is no
obvious replacement (from Lua). Meanwhile we already have
`nvim_echo()` with an `opts` argument.
Solution: Add `err` argument to `nvim_echo()` that directly maps to
`:echoerr`.
|
|
Problem:
`nvim__redraw()` doesn't clamp the lines in the `range` parameter before truncating to int. The resulting range may be empty when the original range contained buffer lines and vice versa.
E.g. for a buffer with 4 lines, these are the redrawn lines:
```lua
{ 2, 2 ^ 31 } -> none (should be { 2, 3 })
{ 2, 2 ^ 32 } -> none (should be { 2, 3 })
{ 2 ^ 32 - 1, 2 } -> { 0, 1 } (should be none)
```
Solution:
Clamp `range` values before truncating to int.
|
|
Problem:
`termopen` has long been a superficial wrapper around `jobstart`, and
has no real purpose. Also, `vim.system` and `nvim_open_term` presumably
will replace all features of `jobstart` and `termopen`, so centralizing
the logic will help with that.
Solution:
- Introduce `eval/deprecated.c`, where all deprecated eval funcs will live.
- Introduce "term" flag of `jobstart`.
- Deprecate `termopen`.

When a terminal application running inside the terminal emulator sets
the cursor shape or blink status of the cursor, update the cursor in the
parent terminal to match.
This removes the "virtual cursor" that has been in use by the terminal
emulator since the beginning. The original rationale for using the
virtual cursor was to avoid having to support additional UI methods to
change the cursor color for other (non-TUI) UIs, instead relying on the
TermCursor and TermCursorNC highlight groups.
The TermCursor highlight group is now used in the default 'guicursor'
value, which has a new entry for Terminal mode. However, the
TermCursorNC highlight group is no longer supported: since terminal
windows now use the real cursor, when the window is not focused there is
no cursor displayed in the window at all, so there is nothing to
highlight. Users can still use the StatusLineTermNC highlight group to
differentiate non-focused terminal windows.
BREAKING CHANGE: The TermCursorNC highlight group is no longer supported.

Problem:
- API functions using `try_start` directly, do not surface the
underlying error message, and instead show generic messages.
- Error-handling code is duplicated in the API impl.
- Failure modes are not tested.
Solution:
- Use `TRY_WRAP`.
- Add tests.
|
|
Problem:
`validate_option_value_args()` returns `OK` even if option name is
invalid or if option doesn't have the supported scope, which leads to
Neovim still trying to erroneously get/set the option in those cases,
which can lead to an assertion failure when `option_has_scope()` is
invoked. This issue miraculously doesn't exist in release builds since
the assertion is skipped and `(get/set)_option_value_for` returns if
there is an error set, but that is not the intended location for that
error to be caught.
Solution:
Make `validate_option_value_args()` return `FAIL` if there is an error
set, which causes the API option functions to return early instead of
trying to get/set an invalid option.
