Before calling "attach" a screen object is just a dummy container for
(row, col) values whose purpose is to be sent as part of the "attach"
function call anyway.
Just create the screen in an attached state directly. Keep the complete
(row, col, options) config together. It is still completely valid to
later detach and re-attach as needed, including to another session.
Problem: both `StatusLineTerm`/`StatusLineTermNC` are now explicitly
used, but `:color vim` does not set them to the values used in Vim.
This might be fine if `:color vim` is treated as "the state of default
color scheme prior the big update", but it seems to be better treated
as "Vim's default color scheme" (how it is documented in its header).
Solution: add `StatusLineTerm`/`StatusLineTermNC` definitions to
'runtime/colors/vim.lua'.
Use explicit foreground colors ('Whte'/'Black') instead of `guifg=bg`
used in source, as the latter caused some problems in the past (if
`Normal` is not defined, `nvim_set_hl()` can't recognize `'bg'` as the
foreground value).
Also realign the rest of the background conditional highlight groups.
Specifically, functions that are run in the context of the test runner
are put in module `test/testutil.lua` while the functions that are run
in the context of the test session are put in
`test/functional/testnvim.lua`.
Closes https://github.com/neovim/neovim/issues/27004.
This is the first installment of a multi-PR series significantly
refactoring how highlights are being specified.
The end goal is to have a base set of 20 ish most common highlights,
and then specific files only need to add more groups to that as needed.
As a complicating factor, we also want to migrate to the new default
color scheme eventually. But by sharing a base set, that future PR
will hopefully be a lot smaller since a lot of tests will be migrated
just simply by updating the base set in place.
As a first step, fix the anti-pattern than Screen defaults to ignoring
highlights. Highlights are integral part of the screen state, not
something "extra" which we only test "sometimes". For now, we still
allow opt-out via the intentionally ugly
screen._default_attr_ids = nil
The end goal is to get rid of all of these eventually (which will be
easier as part of the color scheme migration)
With "intermediate" flag, only using minimal timeout is too short and
may lead to failures.
Also remove the fallback timeout in screen:expect_unchanged(), as having
a different fallback timeout than screen:expect() is confusing.
This is the command invoked repeatedly to make the changes:
:%s/^\(.*\)|\%(\*\(\d\+\)\)\?$\n\1|\%(\*\(\d\+\)\)\?$/\=submatch(1)..'|*'..(max([str2nr(submatch(2)),1])+max([str2nr(submatch(3)),1]))/g
Problem: [security] use-after-free with wildmenu
Solution: properly clean up the wildmenu when exiting
Fix wildchar/wildmenu/pum memory corruption with special wildchar's
Currently, using `wildchar=<Esc>` or `wildchar=<C-\>` can lead to a
memory corruption if using wildmenu+pum, or wrong states if only using
wildmenu. This is due to the code only using one single place inside the
cmdline process loop to perform wild menu clean up (by checking
`end_wildmenu`) but there are other odd situations where the loop could
have exited and we need a post-loop clean up just to be sure. If the
clean up was not done you would have a stale popup menu referring to
invalid memory, or if not using popup menu, incorrect status line (if
`laststatus=0`).
For example, if you hit `<Esc>` two times when it's wildchar, there's a
hard-coded behavior to exit command-line as a failsafe for user, and if
you hit `<C-\><C-\><C-N>` it will also exit command-line, but the clean
up code would not have hit because of specialized `<C-\>` handling.
Fix Ctrl-E / Ctrl-Y to not cancel/accept wildmenu if they are also
used for 'wildchar'/'wildcharm'. Currently they don't behave properly,
and also have potentially memory unsafe behavior as the logic is
currently not accounting for this situation and try to do both.
(Previous patch that addressed this: vim/vim#11677)
Also, correctly document Escape key behavior (double-hit it to escape)
in wildchar docs as it's previously undocumented.
In addition, block known invalid chars to be set in `wildchar` option,
such as Ctrl-C and `<CR>`. This is just to make it clear to the user
they shouldn't be set, and is not required for this bug fix.

Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
The old behaviour (e.g. via `set display-=msgsep`) will not be available.
Assuming that messages always are being drawn on msg_grid
(or not drawn at all, and forwarded to `ext_messages` enabled UI)
will allows some simplifcations and enhancements moving forward.
Opt in to this secret world using
set wildchar=0
" already the default, but remove if non-zero existing config:
set wildcharm=0
now you can map 'wildmode' just like any mode:
cnoremap <tab> <c-z>
function! Spacey()
return getcmdline()[-1:] == "/" ? "\<bs>" : ""
endfunc
cnoremap <expr> / wildmenumode() ? Spacey()."/<c-z>" : "/"
Possibly asked questions:
What about backwards compatibility?
====
Just do nothing and your existing 'wildchar' and 'wildcharm' will keep working.
Doesn't `<c-z>` mean suspend?
====
Not in cmdline mode. If it would then the recommended wildcharm would not
have been `<c-z>` to start with.
My config relies on `:<c-z>` being a synonym to `:<nop>`!
====
just no.

The test.functional.helpers and test.unit.helpers modules now include
all of the public functions from test.helpers, so there is no need to
separately require('test.helpers').
Previously, ordinary redraws were missing from terminal mode. Instead,
there was an async callback that invoked update_screen() on terminal
data regardless of mode (as if :redraw! was invoked by a timer).
This created some issues:
- async changes to an unrelated ordinary buffer were not always redrawn in
terminal mode
- screen cursor position was not properly updated in terminal mode (partial
fix, will be properly fixed in a follow up PR)
- ad-hoc logic was needed for interaction with special states such as
inccommand or horizontal wildmenu.
Instead redraw terminal mode just like any other state. This disables forced
redraws in cmdline mode, which were inconisent which async changes to
normal buffers (which are not redrawn in cmdline mode).
Since uv_os_setenv uses SetEnvironmentVariableW, _wenviron is no
updated. As a result, inconsistency occurs in completion of environment
variable names. Change to use GetEnvironmentStaringsW instead of
_wenviron to solve it.
Unlike the normal wildmenu, the CTRL-D wild-list is not restored by
statusline redraw. (Semantics: ^D is controlled by 'wildoptions' option,
so it's in the "wild..." family.)
TODO: externalize the c_CTRL-D wild-list.
This might be too coarse, but it passes all tests ...
A more nuanced approach might be: only skip the windows whose
statuslines are overwritten by the wildmenu.
Closes#2255Closes#7108
vim-patch:8.0.0710 N/A because of the changes in this commit.
As part of the refactoring in #5119, some vim_strchr() were changed to
strchr(). However, vim_strchr() behaves differently than strchr() when
c is NUL, returning NULL instead of a pointer to the NUL.
Revert the strchr() calls where it isn't known whether c is NUL, since
this causes a semantic change the surrounding code doesn't expect. In
the case of #6650, this led to a heap overrun.
Closes#6650
