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.

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.

When there are multiple empty lines between a paragraph and the cursor
(C in the example below), <a-[>p skips over one of them. Prevent the
check for the extra newline from going out of bounds.
```
a paragraph
C after <a-[>p, the first two lines will be selected
```
A command line argument like +line[:column] can be used to specify a
target line and column for the first file.
This did not work when connecting to a session, because the client
opens its file parameter with `-e "edit file1; edit file2"` which is
executed after the initial buffer position is set. Work around this by
passing the position to the first file and avoid moving the cursor
in unrelated files.
Reproduce:
kak -s foo
kak -c foo +4:11 README.asciidoc
The Ubuntu Disco distribution comes with `g++` v8 installed by default,
which is not able to deduce the return type of a particular call to
`transform()`.
This commit explicitly declares the return type to mitigate that
problem, and allow the file to compile.
