Commit d470bd2cc (Make numeric registers setable, 2017-02-14) removed
the user-provided StaticRegister::operator= in favor of a set()
member function, so this comment is no longer valid.
Recently, switch completion were given the menu behavior.
Unfortunately this breaks cases like
:echo -- -mark<ret>
where the hypothetical user wanted to actually display "-mark", not
"-markup".
Simply bail if there is a double-dash. This is not fully correct,
for example it wrongly disables switch completion on
echo -to-file -- -
but that's minor, we can fix it later.
In future, we should reuse the ParametersParser when computing completions,
which will obsolete this workaround.
Commit 217dd6a1d (Disable history when executing maps, 2015-11-10)
made it so with
map global normal X %{:echo 123<ret>}
X does not add to prompt history (%reg{:}).
Unfortunately this behavior was not extended to mappings in the "user"
keymap, nor to mappings in custom user modes.
In my experience, not adding to history is almost always the expected
behavior for mappings. Most users achieve this by adding a leading space:
map global user X %{: echo 123<ret>}
but that's awkward. We should have good defaults (no nnoremap)
and map should work the same way across all modes.
Fix this by also disabling history when executing user mappings. This
is a breaking change but I think it only breaks hypothetical scenarios.
I found some uses where user mappings add to history but none of them
looks intentional.

This allows to select completions without pressing Tab.
There are two different obvious ways to add the menu bit.
1. When creating the "Completions" object, pass the
Completions::Flags::Menu parameter.
2. If there is a completer function like "complete_scope", wrap
it, e.g. "menu(complete_scope)".
I have settled on always using 2 if there is a completer function
and 1 otherwise.
The advantage of 2 over 1 is that it allows to use the completer
function in a context where we don't want the menu behavior
(e.g. "complete-command").
---
Now the only* completion type where we usually don't use menu behavior
is file completion. Unfortunately, menu behavior has poor interaction
with directories' trailing slashes. Consider this (contrived) example:
define-command ls -docstring "list directory contents" -params .. %{
echo -- %sh{ls "$@"}
}
complete-command -menu ls file
Run ":ls kakoun<ret>". The prompt expands to ":ls kakoune/"
before executing. Next, run ":<c-p>". This recalls ":ls kakoune/"
and immediately selects the first completion, so on validation,
the command will be ":ls kakoune/colors/", which is weird.
[*] Also, expansions like %val{bufname} also don't use menu
behavior. It wouldn't add value since validation doesn't add a
closing delimiter. I have an experimental patch that adds closing
delimiters automatically but I'm not sure if that's the right
direction.
This makes "cd<space><ret>" change to the first completion,
not to $HOME. This might be surprising but it should make sense.
I don't have a concrete motivation but this should save a Tab press
in some scenarios.
We allow to abbreviate scopes ("set g" means the same thing as "set
global") but that feature is a bit obscure. Users might figure out the
menu completion behavior faster, so let's maybe use it here as well?
Not really attached to this but it enables the next commit to use
menu() for completing scopes.
This refactoring is possible because we always have
params[token_to_complete].length() == pos_in_token
---
Instead of three separate functions, I originally tried to add
template arguments to complete_scope(). That worked fine with g++
12.1 but clang 14.0 complained when wrapping a menu() around a
complete_scope() that relied on defaulted template arguments:
commands.cc:1087:20: error: no matching function for call to 'menu'
make_completer(menu(complete_scope), menu(complete_hooks), complete_nothing,
^~~~
commands.cc:116:6: note: candidate template ignored: couldn't infer template argument 'Completer'
auto menu(Completer completer)
^
On a command prompt like
"set-option -remove buffer aligntab "
we fail to show the aligntab-specific info . Fix this by skipping a
leading -remove, just like we skip -add.
Add an explicit specialization of contains() because otherwise I'd
need to write something like
contains(Array{"-add", "remove"}, param)
This gives the "prompt" command the same "-menu" switch as
"complete-command" and "define-command". I don't think anyone has
asked for it but it seems like a good idea?
Both "define-command" and "prompt" use the same logic, so share
it. This will make it easy to implement "prompt -menu".
This reveals a problem with PromptCompleterAdapter: when converting
it to std::function and then to bool, it always evaluates to true
because it has an operator(). However, it should evaluate to false
if the adaptee holds no valid function (e.g. is a default-constructed
std::function). Otherwise we try to call a non-existant function. Tweak
PromptCompleterAdapter to work for empty inputs.
If I type
:echo -mx
I get no completions, even when I move the cursor on the x.
If I replace the x with a k, I get a completion "-markup".
The odd thing is that if I accept the completion while the cursor is
on the k, then the commandline will be
:echo markupk
Evidently, the characters under cursor (x/k) influence the completion
(actually all letters right of the cursor do), but they are not
incorporated in the final result, which is weird.
I think there are two consistent behaviors:
1. Compute completions only from characters left of the cursor. We already
do this in insert mode completion, and when completing the command name
in a prompt.
2. Compute completions from the whole token, and when accepting a completion,
replace the whole token.
Most readline-style completion systems out there implement 1. A
notable exception is fish's tab-completion. I think we should stick
to 1 because it's more predictable and familiar. Do that.
This allows us to get rid of a special case for completing command
names, because the new behavior subsumes it.
In fact, I think this would allow us to get rid of most "pos_in_token"
or "cursor_pos" completer parameters. I believe the only place where we
it's actually different from the end of the query is in "shell-script"
completers, where we expose "$kak_pos_in_token". I think we can still
remove that parameter and just cut the commandline at the cursor
position before passing it to a "shell-script" completer. Then we
also don't need "$kak_token_to_complete" (but we can still keep
expose them for backwards compatibility).
Just like in the parent commit, this requires us to use a non-owning
type. Technically, these strings all benefit from SSO, so there is
no lifetime issue, but we can't deduce that from the types.
I guess we could use InplaceString just as well.
This means that typing
:add-highlighter g c 80
results in
:add-highlighter global/ column 80
Paths for add-highlighter do not get the menu behavior because we
want to be able to type "global/foo" even if "global/foobar" exists.
complete() merely iterates over its input, so we can pass it a range
instead of a vector. For some reason, this requires specifying the
type of the static array, or else its elements become String which
triggers this assertion:
static_assert(not std::is_same<decltype(*begin(container)), String>::value,
"complete require long lived strings, not temporaries");
Specify the type with an explicit Array<StringView, 8>. This is
pretty ugly but the alternative of appending "_sv" to every single
array element seems worse?
If we modify the vector of user modes while complete() is iterating
over, we could crash -- but that scenario is impossible since both
only happen inside the single-threaded server process.
We already use the menu behavior in complete_command_name(); let's do
the same for switches, since we can complete all valid inputs and
it can save a Tab key in some scenarios.
CommandManager::complete is fairly complex. We can't expect callers
to add the menu bit when appropriate, so we currently do it here.
The next commit will give switch completions the menu behavior, so this
is necessary so we can still type "echo --" without an auto-expansion
to "echo -to-file".
"complete_alias_name" is a better name then "complete_alias" because
it's consistent with more similar names, which are:
complete_client_name
complete_command_name
complete_module_name
complete_option_name
complete_register_name
complete_scope
complete_face
We define
using PromptCompleter = std::function<Completions (const Context&, CompletionFlags,
StringView, ByteCount)>;
Some command completers are *almost* convertible to PromptCompleter;
the only difference is the string type of the prefix argument.
The later commits in this series want to use menu() on the
completers. Enable this by harmonizing the types.
Instead of triming only buffer ranges, add a trim_from method to
display line to keep the initial N columns, we know how many columns
are used by non-trimable widgets in DisplaySetup::widget_columns so
we can just pass this.
Also restore the previous logic for face merging
Fixes#4670
Make the column highlighter faces final, and change final logic to
give precedence to the base face when both the base and new face are
final.
Fixes#4669
Terminals that support CSI u escape codes (like iTerm2, Kitty and foot)
allow us to map <s-backspace> independently of <backspace>.
Users expect that <s-backspace> does the same as <backspace>,
especially when typing ALL_CAPS. Make it so.
The first version of 0cf719103 (Make Shift+Space insert a space in
insert mode, 2022-02-09) did that already but I later dropped it
because I wasn't sure if it's right.
Always start with full buffer lines and trim the display buffer at
the very end, treat non-range display atoms as non-trimable in that
case and keep track of how many columns are occupied by "widgets"
such as line numbers or flags.
Fixes#4659
`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
Insert mode completions are accepted by typing any key. For example,
if there is a completion "somefunction()", then typing
some<c-n>;
will insert
somefunction();
and then the InsertCompletionHide hook will fire. The hook parameter
is a range that contains the entire thing: the actual completion plus
the trailing semicolon that closed the completion menu.
The [original motivation] for the hook parameter was to support
removing text inserted by completion, so we can apply text edits
or expand snippets instead. One problem is that we don't want to
remove the semicolon. Another problem came up in a discussion
about [snippets]: let's say we have a snippet "add" that expands to
add(?, ?)
where ? are placeholders. After snippet expansion the cursor replaces
the first placeholder. If I type "ad<c-n>1" I expect to get "add(1, ?)".
If the InsertCompletionHide hook only runs after processing the "1"
keystroke, this is not possible without evil hacks.
Fix these problems by running InsertCompletionHide when a completion is
accepted _before_ inserting anything else into the buffer. This should
make it much easier to fully implement [LSP text edits]. I doubt
that anyone besides kak-lsp is using the hook parameter today so this
should be a low-risk fix.

Ubuntu 20.04 ships GCC's libstdc++ 10 from 2020 which implements
std::to_chars() for integers but not for floats. Use the float overload

Since "Array" has no constructor, the compiler uses aggregate
initialization. Only recent g++ seems to be smart enough to deduce
template arguments in this case. Help other compilers by adding a
deduction guide. The deduction guide needs to count the array elements
to infer the array size, hence we need to remove braces. Happily,
this is allowed and it's also what std::array does.

Deleting a buffer resets normal mode on all clients that were
displaing that buffer, but ScopedForceNormalMode that are used
from user mode do not take this possiblity into account on
destruction, which leads to deleting the last normal mode from
the context, ending up with an empty mode stack.
Fixes#3909
This fixes a crash when using kak-lsp with bash-language-server. The
issue is that the second read() in parse_quoted may read past the end of
the string. If this happens and the condition on line 126 is false,
then the loop on line 119 will continue to read past the end of the
buffer since it checks for state.pos != end instead of state.pos < end,
which will likely result in a crash. The fix is to add a check for the
buffer end before the second read. The added test fails without the
change and passes with the change.
Given a completer option with two applicable completions
text|select-cmd1|menu-text1
text|select-cmd2|menu-text2
Kakoune will only show one of them, because they will insert the
same text.
Some language servers send completions like this, for example if
two different importable modules provide the same name. This can be
reproduced using intelephense in this PHP file (cursor is %())
<?php
namespace namespace1;
class sometype {}
?>
<?php
namespace namespace2;
class sometype {}
?>
<?php
namespace test;
some%()
?>
Both completions insert "sometype". The import statement will be
added in an InsertCompletionHide hook by kak-lsp (it uses select-cmd
to determine which completion was selected).
To support this use case, refine the duplicate detection to not filter
out completions with different select-cmd values.
Parsing a (non-valid) font with a comma in the name of the base colour
makes Kakoune crash. It is not a valid face, but Kakoune should just
return an error message instead.
Reproducer:
:set-face global foo ,red@,blue
Note the comma "," after the "@". This is not a valid base name, and it
leads to a crash. Let's see what happens.
At the beginning of parse_face(), we have the following code:
auto bg_it = find(facedesc, ',');
auto underline_it = bg_it == facedesc.end() ? bg_it : std::find(bg_it+1, facedesc.end(), ',');
auto attr_it = find(facedesc, '+');
auto base_it = find(facedesc, '@');
[...]
auto colors_end = std::min(attr_it, base_it);
After this:
- bg_it points to ",red@,blue"
- bg_it != facedesc.end(), so we have underline_it pointing to the first
comma after bg_it. This means that underline_it points to ",blue"
- base_it points to "@,blue"
- attr_it points to the end of facedesc (no "+" marker), so colors_end
points to base_it, "@,blue"
Later in the code, just after parsing the foreground and background
colours, we have:
if (underline_it != facedesc.end())
face.underline = parse_color({underline_it+1, colors_end});
When passing {underline_it+1, colors_end} to parse_color(), we pass in
fact iterators pointing to {",blue", "@,blue"}. Because the second one
starts _before_ the first one in the string, this means that the
resulting string is considered to have a _negative_ length.
parse_color() passes the string to str_to_color(), who fails to turn up
the colour, and attempts to throw:
throw runtime_error(format("unable to parse color: '{}'", color));
The variable "color" still has this negative length, and this goes all
the way down to an assert in src/units.hh where we expect that string to
be >= 0, and we crash on the assertion failure.
For similar reasons, we also get a crash if the comma comes after the
marker for the face attributes:
:set-face global foo ,red+,a
To fix both cases, let's add a check to make sure that the underline_it,
marked with a comma, never gets detected as present and pointing after
colors_end, be it "@" or "+".
As pointed out in [1], when insert mode autocomplete is disabled,
<c-n> could be used to activate insert mode completions temporarily
[2]. This regressed in 6f7c5aed (Do not show custom completions when
autocomplete is off, 2022-01-03). Fix this by enabling completions
on <c-n>/<c-p>. This allows us to remove a special case for explicit
completers.
Alternative behavior (future?): make <c-n> toggle completion like
<c-o>. This can be done today, as suggested by Screwtape on IRC:
map global insert <c-n> %{<c-o><c-n><a-;>:toggle-ctrl-n<ret>}
define-command toggle-ctrl-n %{
hook global InsertCompletionShow .* %{ map window insert <c-n> <c-n> }
hook global InsertCompletionHide .* %{ unmap window insert <c-n> <c-n> }
}
[1] https://github.com/mawww/kakoune/pull/4493#issuecomment-1031189823
[2] <c-n> completion only lives for the lifetime of the completion
menu, whereas <c-o> lasts until you exit insert mode. This means
that autocompletion is much more convenient than <c-n> or <c-x>f,
because those require an explicit completion request for each
path component.
The ThreadedRegexVM implementation does not execute split opcodes as
expected: on split the pending thread is pushed on top of the thread
stack, which means that when multiple splits are executed in a row
(such as with a disjunction with 3 or more branches) the last split
target gets on top of the thread stack and gets executed next (when the
thread from the first split target would be the expected one)
Fixing this in the ThreadedRegexVM would have a performance impact as
we would not be able to use a plain stack for current threads, so the
best solution at the moment is to reverse the order of splits generated
by a disjunction.

This will unfortunately break some use case which will require
using wrapper scripts to add the necessary newline. It is however
harder to do the contrary, and it makes a lot of other use case
possible, such as checksuming.
Fixes#3669
After a while it seems clear changing this is much more ergonomic
and restoring it with pure config is impractical as we need to map
all lower case keys.
As reported in [1], completions provided by "set global completers
option=my_completion" activate insert mode autocompletion, even when
the autocomplete option does not have the insert mode flag.
This happens because InsertCompleter::on_option_changed() calls
InsertCompleter::setup_ifn(), which shows the completion pager.
Fix this by computing whether the completion pager is enabled;
otherwise we can return early from setup_ifn().
The completion pager is enabled if the autocompletion bit is set,
or if the user has requested explicit completion.

Only ui type Terminal is intended to be a user interactive session.
If your ui type is not Terminal, don't worry about making

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

Synchronized output does not work well with various terminals

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.

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

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

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.
