Problem: if buf_free_all autocommands open a terminal, it will remain open after
the buffer is freed.
Solution: close terminals again later, this time while blocking autocommands.
Did consider terminal_open checking stuff like b_locked_split instead, but
that's set during BufHidden, etc., which doesn't mean the buffer's being wiped.
Problem: Wrong terminal scrollback if BufFile* autocommand drains PTY
output but doesn't process the pending refresh.
Solution: Refresh scrollback before refreshing screen in terminal_open()
if scrollback has been allocated.
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.
Usually, terminal_close() calls refresh_terminal(), which allocates the
scrollback buffer, and term_may_alloc_scrollback() in terminal_open()
won't dereference the buffer. However, refresh_terminal() is not called
during Nvim exit, in which case a heap-use-after-free may happen if
TermOpen wipes buffer. Check for non-NULL buf_handle to avoid that.
Problem: When TermOpen polls for enough events to use the scrollback
buffer, scrollback is lost until the next terminal refresh.
Solution: Allocate the scrollback buffer when it's needed.
Problem:
Test sometimes fails on macos:
test/functional/terminal/channel_spec.lua:96: Expected objects to be the same.
Passed in:
(number) 3
Expected:
(number) 2
Solution:
Retry a few times.
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`.
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.
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)
Problem:
Unlike termopen(), nvim_open_term() PTYs do not carriage-return the
cursor on newline ("\n") input.
nvim --clean
:let chan_id = nvim_open_term(1, {})
:call chansend(chan_id, ["here", "are", "some", "lines"])
Actual behavior:
here
are
some
lines
Expected behaviour:
here
are
some
lines
Solution:
Add `force_crlf` option, and enable it by default.
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: `chansend()` on Windows sends lines in reverse order.
Cause: Using \n instead of \r\n for newlines on Windows.
Solution: on Windows, use CRLF newline characters.
Fixes#18501
- Fix the problem that chanclose() does not work for channel created by
nvim_open_term().
- Fix the problem that the loopback channel is not released.
- Fix the error message when sending raw data to the loopback channel.
