Merge all lookarounds into the same instruction, merge splits, merge
literal ignore case with literal...
Besides reducing the amount of almost duplicated code, this improves
performance by reducing pressure on the (often failing) branch target
prediction for instruction dispatching by moving branches into the
instruction code themselves where they are more likely to be well
predicted.
Only ui type Terminal is intended to be a user interactive session.
If your ui type is not Terminal, don't worry about making
the tty your stdin if fd 0 is not a tty.
This allows json-rpc commands sent via stdin to be acted up rather
than sent to a fifo (which is the default behavior for kakoune).
Does not change the behavior for Terminal ui sessions
Now that Kakoune opts into extended key reporting, <c-i> is correctly
reported and hence needs to be mapped to forward jump.
We still need to keep <tab> mapped to it for legacy terminals.
Should fix#4333
Closing/reopening the read side seems to sometimes lead to
end-of-file not being received, leaving some extra data unexecuted.
The FDWatcher stays disabled during the executing of the fifo
commands so this should not enable any more commands to be executed
until we get back from the CommandManager and reset the FDWatcher
fd to to fifo read end.
Fixes#4410
ARM uses @ as a comment character, so %progbits must be
used in place of @progbits here. This change fixes the
build on armv7 FreeBSD 13.0.

Cppcheck produces the following warnings:
```
shared_string.hh:27:49: portability: Shifting signed 32-bit value by 31 bits is implementation-defined behaviour
shared_string.hh:27:49: error: Signed integer overflow for expression '1<<31'.

Cppcheck produces the following warning:
```
keymap_manager.hh:54:37: performance: Function parameter 'user_mode_name' should be passed by const reference.

Enable it if supported by default, let the user override it with
the existing terminal_synchronized ui option.
This should finalize work discussed on #4317
They are quite different use cases, and this allow moving InsertMode
to input_handler.hh which is what uses it.
This also cleans up the code as we can get rid of get_insert_pos and
rely more on SelectionList::for_each.
This commit prevents `ga` from returning a “no last buffer” error
when the previously displayed buffer was removed.
Since the jumps list keeps track of the order in which buffers were
displayed already, handling arbitrary `delete-buffer`s as well,
cycle through it to implement `ga` instead of storing a pointer.
Note that this commit doesn't take into account buffer flags that
might exclude some buffers from being cycled over by commands.
Fixes#1840
The current implementation allows users to declare mappings in the
`goto` and `view` modes with uppercase letters, but doesn't consider
case to be meaningful.
This quirk is also inconsistent as hitting an unmapped key will quit
the mode menu without complaints, but hitting a key that isn't in it
will work if it has a lowercase mapping equivalent.
Fixes#3976
Just validate if line changed or not. This should avoid flickering
on terminals such as the linux console that eagerly redraw on line
deletions. Unfortunately this means drawing will use more data and
might add a bit of latency on slow links.
Fixes#4317Fixes#4320
kak-lsp uses these faces to mark errors inside the buffer, instead of the Error
face which is much more jarring, and which does not have an associated warning
face. Since the :spell command marks errors inside the buffer, it's also updated
to use this new face.
Adding these faces to Kakoune makes it more likely that colorschemes will
automatically do the right thing when used with kak-lsp, and makes it possible
to use a subtle appearance (like curly underlines) for in-buffer errors while
keeping Kakoune errors bold and jarring as they should be.
Add support for a third color in face definition that controls
the underline and a 'c' attribute for curly underline (that takes
precedence over 'u' if both are specified)
Allow empty colors to mean default, so that `,,red+u` means the
same as `default,default,red+u`
Fixes#4138
Commit 2289f350 ("Remove command parsing Reader and just track a
ParserState") introduced a small regression in parse_percent_token()
because we failed to recognize a token like %val{ as percent-expansion.
I tried to add a test case but a UI test doesn't seem possible, e.g.
kak -ui json -e "exec ':echo %opt{<tab>}<ret>'"
prints: 'exec': option not found: ''
Make String::Data use trivial copy of the short/long union to avoid
unnecessary branching there, inline release() as it can be elided by
the compiler on moved-from Strings.
Display a whitespace in place of the uncovered half of the codepoint.
(I know this is incorrect and we should be considering grapheme clusters
instead of codepoints, but this is a far bigger refactoring and another
can of worms to handle with terminal emulators).
Fixes#4262
Synchronized output does not work well with various terminals
(including the linux console). It should also be unnecessary when
not going through a slow link.
This will eventually be removed if it is not proven to be useful
to some users.
TerminalUI::suspend() is responsible for undoing all Kakoune's modifications to
the terminal state, actually suspending the process, then re-applying all the
modifications after Kakoune wakes back up.
Previously, the "undo" and "reapply" steps for termios settings were both after
the suspend point, so on some platforms they were incorrect when the user
arrived back at the shell prompt.
Now, the termios "undo" step is back before the suspend point, and the undo and
reapply steps should be in exactly reversed order.
Fixes#3488.
In terminals that support it, this sequence causes the terminal to not redraw
*its* output until the application has finished, reducing redraw flickering.
The sequence is defined in:
https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec
...and is apparently also supported by kitty and libVTE.
Fixes#3482.
insert blank seems to behave differently between terminals and would
be less efficient because it still has to shift all following characters
(that we will overwrite anyway).
Fixes#3437
Diff against known state and insert/erase relevant lines.
Erase everything first to avoid insertion invalidating lines that
get out of the terminal at bottom.
This should reduce flicker, by avoiding transient states where
info/menu windows are not displayed, and paves the way for proper
diffing of the screen.
Log error to debug buffer and Change the 'waiting for shell' face
to 'Error'.
Update the 'waiting for shell' message when the shell has exited
but Kakoune is still waiting on stdin/stdout/stderr to be closed.
Those fifos are accessible during %sh{...} blocks, the command fifo
executes commands written to it once the write end side is closed
(multiple open/write/close sequences are supported), the response
fifo is a simple helper fifo available to write response back to
the shell process
An example use of this feature is to request some list options
content from without being limited by the environment size:
```
%sh{
echo "echo -to-file $kak_response_fifo -quoting shell -- %opt{some_list}" > $kak_command_fifo
eval "set -- $(cat $kak_response_fifo)"
}
```
