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)"
}
```
If a %sh{} script refers to any variables multiple times they are all multiply
included in the environment. Example: if a %sh{} invocation refers to
${kak_buffile} 5 times, the environment will have "kak_buffile=..." repeated 5
times and so on. This repetition happens for each multiply used variable that
is passed into the environment.
The variable should, of course, be only passed into the environment once. This
commit should fix this issue.
The real technical limit is with lines bigger than 2 GiB and buffers
with more than 2 Gi lines, refactor buffer loading to make it possible
to load those files.
Fix an overflow with the hash_data function at the same time
This fixes an issue where completion would still be provided after
the closing character of a token, which could then get frustrating
combined with auto-insertion of completions.
For example, inserting `%{<newline>}` for a command-completed token
(such as the commands for a hook) would still trigger completion right
after the `}` and that completion would get auto-inserted **replacing**
that closing `}`.
Do not use a shared kakoune/ directory for all users to avoid the
complexity of having to set the sticky bit on that dir, resolve the
session directoy only once by using a static variable and an
immediately evaluated lambda.
This fixes an annoyance whenver using `su` and having Kakoune refuse
to start due to XDG_RUNTIME_DIR still being set.
For historical reasons, mouse events represent keyboard modifiers as a bitfield,
but keyboard events represent modifiers as a bitfield-plus-one. For example, a
mouse event with an Alt modifier will use the value 4, but a keyboard event will
use the value 5.
Previously, I refactored the parse_mask() helper to do the subtraction itself,
instead of requiring the caller to do it. This made keyboard-event decoding much
cleaner, but I didn't realise it broke mouse-event decoding. Now the subtraction
is done only for keyboard events.
Fixes#4176.
In some cases, it may be difficult to easily spot the area out of the buffer
(bad color scheme, small font, superimposed windows).
This patch adds two ncurses ui_options to bypass this problem:
- `ncurses_padding_char`, to configure the padding character,
- `ncurses_padding_fill`, to indicate whether to fill the padding line
(or to display a single character).
The default config is the legacy one (a single "~").
- Add the Narrow No-Break SPace (0x202F, NNBSP) to the list of handled
spaces in the show-whitespace highlighter.
- Do not add an aditional option, just handle it like NBSP, with the same highlight character.
Quote by wrapping in quotes if we are replacing the whole token,
using backspaces if the completion only adds to it.
This ensure that the inserted completion will be correctly parsed
once validated.
Fixes#4121
Kakoune now knows about all the keypad keys listed in:
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-PC-Style-Function-Keyshttps://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-VT220-Style-Function-Keys
The VT220-style encodings are used to for modified numeric keys when NumLock is
off. For example, consider the 8/Up key:
| Modifiers | Sequence | Notes |
|-----------------|-------------|-------------------|
| Unmodified | CSI A | Ordinary up arrow |
| Shift | SS3 2 x | Shift-8 |
| NumLock | 8 | Ordinary 8 |
| Shift + NumLock | CSI 1 ; 2 A | Shift-Up |
Note that even though the terminal distinguishes between keypad and regular keys,
Kakoune maps keypad keys onto regular keys - keypad Enter is still <ret>, it
just supports more modifiers than the regular Enter key.
It's useful for parsing modifier masks in all kinds of sequences, not just CSI
sequences. Also, since the modifier mask always has "1" as "no modifiers",
do the subtraction inside parse_mask() instead of when calling it.
This avoids 100% CPU usage when we have pending fifo input while running
a shell process, as we will not end-up busy looping in pselect but not
reading the available data due to being only processing urgent events.
When a replaced buffer range atom was starting exactly at the
location we wanted to split onto the code would split *after*
that atom instead of before.
Fixes#4052
This avoids an issue when using `su` and running Kakoune which creates
a session directory owned by root and prevents the user from creating
more sessions.
Different terminals send different codes to indicate backspace, usually one of
\x08 or \x7f, so Kakoune blindly treated both as backspace. However, a given
terminal is only likely to use one of those, and mnemonic control codes like
<c-h> are a precious resource so we should endeavour to keep backspace and
<c-h> separate when we can. Luckily, termios tells us what code our terminal is
currently using, and Kakoune already reads the information at startup, so we can
just use that information.
Thanks to @krobelus for figuring out the C++ syntax required.
Fixes#3863.
Add that libexec directory to the PATH instead of the current kak
binary directory to avoid impacting other commands.
The libexec directory currently only contains a symlink back to
the Kakoune binary.
Various paths can run arbitrary commands (callbacks, hooks) which
could lead to the InputMode being popped off the mode stack, but
contrarily to the on_key method, we had no guarantees to be kept
alive.
Add a keep_alive RefPtr to this to ensure the mode survives till
the end.
Fixes#3915
When doing line completion, we previously used to not complete the line
if it had different indent to the potential completion.
This commit changes the behaviour to ignore indentation when completing lines.
Unfortunately this breaks some pretty useful use cases, such as inserting a
command ending with a new-line (as it now leads to an addtional command being
auto-completed on validation)
This reverts commit aab0be529f.
When pasting many words with <a-p> we can end-up with a huge
concatenated word and many selections, the previous code ended
up iterating from each selection cursor to that word start and
end to find the word under the cursor.
This could lead to performance issue as each selection would
trigger iteration on that huge word. This is unnecessary as
word completion has a word length limit, so we now take it into
account to avoid iterating to far from the cursor position.
The previous code was advancing from the general insertion point
for all selection, instead of iterating only once from insertion
point until the end of inserted text.
0 means stdin was closed, this is quite unexpected as we would usually
get a SIGHUP, but it looks like in some rare case this happens and
it leads to an infinite loop trying to handle stdin events (as it
will always be readable from now on).
Fixes#3557
Previously, Kakoune only handled ctrl-codes less than 27, representing them as
lower-case ASCII codes. For regular keys like <c-a>, that worked fine. However,
NUL became the unorthodox <c-`> and other ctrl-symbols (<c-\>, <c-]>, <c-_>)
weren't supported at all.
Now NUL is rendered as the more comfortable <c-space>, and the other ctrl-symbol
codes are properly decoded.
Fixes#2553.
`-atomic` becomes `-method replace` and `-method overwrite` is now
supported explicitely instead of only available through the
writemethod option.
Fixes#3827
Giving an explicit register uses its content for the default value
to use if the user does not enter anything. This enables:
`set-register a %{commands}; execute-keys '"a:<ret>'`
`set-register a %{shell script}; execute-keys '"a|<ret>'`
...
This provides a nice way to avoid the need to escape keys to use
those normal mode commands.
Fixes#3825
This avoids a frustrating behaviour where Kakoune autoinserts the first
command name when hitting <space> after a ; in a command line. It also
fixes the empty prompt case that was auto-completed instead of executing
the default command.
We try to detect when compiling under Cygwin, so we can set the
_XOPEN_SOURCE define which lets us use wcwidth(). We look for the
string "CYGWIN" in the uname, which looks like:
CYGWIN_NT-10.0
MSYS2 is also based on Cygwin, so all of the above should still work.
However, we detect Cygwin by looking for the string "CYGWIN" in the
uname. In MSYS2, the uname looks like:
MSYS_NT-10.0-18362
This patch looks for the string "_NT" instead of the string "CYGWIN"
in the uname, since it's common to both environments. This fixes a
compilation error on MSYS2.
The menu flag signifies that only the completions are valid arguments,
hence it makes sense to auto insert the best one on space.
Because full match is always considered the best match in completion
ranking, this should always have a reasonable behaviour.
This makes it harder to enter a hidden command, but completion can
always be disabled via <c-o> or by quoting in those rare cases.
Because no flags were set for regex matching, the regex engine was
assuming that the subject string past-the-end matched a end-of-line.
As the subject string already ended with a \n character, the regex
engine processing of the "past-the-end" position would match '^$'
as ^ matched past the existing \n and $ matched the assumed
end-of-line.
Fixes#3799
Previously we would just bypass that hook making it impossible to
act on the inserted text when triggering an explicit completion after
inserting text from the previous completer.
This one has been a long time coming, I am still concerned this could
impact performance a lot. This hook does *not* trigger for capture
registers (0-9) or any other dynamic registers (that are not writable).

ncurses_ui.cc:759:59: error: non-constant-expression cannot be narrowed from type 'unsigned int' to 'Key::MouseButton' in initializer list [-Wc++11-narrowing]

Only include the value for int/str/bool options, for the rest just
write '<option name>=...'.
This should reduce the cost of some patterns such as repeatedly adding
a value inside a list option.
It seems very unlikely that the actual value would be matched by
a hook regex string for non primitive types.
Similarly to the <semicolon> key, make it easier to write
`:execute-keys` commands by replacing <percent> with `%`.
Highlighters can keep escaping the sign when regular expressions are
not quoted, but built-in scripts that use `%` as an editing primitive
have been modified to use the named key, for clarity.
Ranges specified with a +<length> were inconsistent, with +0 meaning
an empty range, while +1 meant a two character long range (first character
+ the following one). Change that to mean a single character.
Fixes#3479
