libvterm v0.3 supports reflow of terminal buffer when Nvim is resized
Since v0.3 is now a required dependency, enable it by default to find
(and fix) possible issues.
Note: Neovim's scrollback buffer does not support reflow (yet), so lines
vanishing into the buffer due to a too small window will be restored
without reflow.
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")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
- Avoid using platform-specific shell, it failed in MINGW_64 env.
- tty-test.c echos our input, which is exactly what we need for this test.
- Test fails correctly if 894f6bee54 is reverted.
wp->w_height_inner now contains the "inner" size, regardless if the
window has been drawn yet or not. It should be used instead of
wp->w_grid.Rows, for stuff that is not directly related to accessing
the allocated grid memory, such like cursor movement and terminal size
Let the terminal dictate the normal-mode cursor position. This will be
disorienting sometimes, but it is closer to what users expect vs always
going to the last line.
It is otherwise impossible to determine which test failed sanitizer/valgrind
check. test/functional/helpers.lua module return was changed so that tests which
do not provide after_each function to get new check will automatically fail.
Previously, the screen test was expecting the screen state to be
identical to the previous screen test in `thelpers.screen_setup()`,
which is indeterministic. (The later screen test can accidentally
still see the previous identical state). The solution is to add a test
for a intermediate different state.
- Modify tty-test to allow easier control over the terminal
- Add a new directory with various terminal tests/specifications
- Remove a pending job/pty test.
- Flush stdout in Screen:snapshot_util() (avoid waiting for the test to finish)
- Replace libuv sigwinch watcher by a sigaction handler. libuv randomly fails to
deliver signals on OSX. Might be related to the problem fixed by
@bbcddc55ee1e5605657592644be0102ed3a5f104 (under the hoods, libuv uses a pipe
to deliver signals to the main thread, which might be blocking in some
situations)
