Text pasted into Kakoune's normal mode is interpreted as command
sequence, which is probably never what the user wants. Text
pasted during insert mode will be inserted fine but may trigger
auto-indentation hooks which is likely not what users want.
Bracketed paste is pair of escape codes sent by terminals that allow
applications to distinguish between pasted text and typed text.
Let's use this feature to always insert pasted text verbatim, skipping
keymap lookup and the InsertChar hook. In future, we could add a
dedicated Paste hook.
We need to make a decision on whether to paste before or after the
selection. I chose "before" because that's what I'm used to.
TerminalUI::set_on_key has
EventManager::instance().force_signal(0);
I'm not sure if we want the same for TerminalUI::set_on_paste?
I assume it doesn't matter because they are always called in tandem.

Including this here because grandparent parent commit broke completions
for "edit -fifo".

Fixes #4839

Recent changes for selection-undo added an assertion that triggers
when a mouse-drag overlaps with an insert mode, because both events
record selection history. However this is actually fine. The one
that finishes last concludes the selection edition, while the other
one will be a nop.
The test could be simpler (i.e. not require sleeps) but I figured it
doesn't hurt add this since we don't have any comparable tests.

With overlapping selections, pasting after breaks assumption of
SelectionList::for_each as our changes are no longer happening in
increasing locations.
We hence cannot rely on the ForwardChangeTracker in that case and
have to rely on the more general (and more costly) ranges update logic.
This interacts poorly with paste linewise pastes and we try to preserve
the current behaviour by tracking the last paste position.
Overall, this change really begs for overlapping selections to be
removed, but we will fix them like that for now.

From the issue:

Fix this by recording selection changes and allowing simple linear
undo/redo of selection changes.
The preliminary key bindings are <c-h> and <c-k>.
Here are some other vacant normal mode keys I considered
X Y
<backspace> <minus>
# ^ =
<plus> '
unfortunately none of them is super convenient to type. Maybe we
can kick out some other normal mode command?
---
This feature has some overlap with the jump list (<c-o>/<c-i>) and
with undo (u) but each of the three features have their moment.
Currently there's no special integration with either peer feature;
the three histories are completely independent. In future we might
want to synchronize them so we can implement Sublime Text's "Soft
undo" feature.
Note that it is possible to restore selections that predate a buffer
modification. Depending on the buffer modification, the selections
might look different of course. (When trying to apply an old buffer's
selection to the new buffer, Kakoune computes a diff of the buffers
and updates the selection accordingly. This works quite well for
many practical examples.)
This makes us record the full history of all selections for each
client. This seems wasteful, we could set a limit. I don't expect
excessive memory usage in practice (we also keep the full history of
buffer changes) but I could be wrong.
Closes #898

To be able to undo selection changes, we want to record selections
from all commands that modify selections. Each such command will get
its own private copy of the selections object.
This copy will live until the command is finished executing.
All child commands that are run while the command is executing,
will also use the same copy, because to the user it's all just one
selection change anyway.
Add an RAII object in all places where we might modify selections.
The next commit will use this to create the private selections copy
in the constructor (if there is none) and remove redundant history
items in the destructor.
We could avoid the RAII object in some places but that seems worse.
For lifetimes that don't correspond to a lexical scope, we use a
std::unique_ptr. For lambdas that require conversion to std::function,
we use std::shared_ptr because we need something that's copyable.
|

This makes the function easier to find for newcomers because
to_string() is the obvious name. It enables format() to do the
conversion automatically which seems like good idea (since there is
no other obvious representation).
Of course this change makes it a bit harder to grep but that's not
a problem with clang tooling.
We need to cast the function in one place when calling transform()
but that's acceptable.

can_auto_insert_completion already requires the menu bit.
|
|
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.

Besides being redundant, it is easy to press esc by mistake/habit

`<c-r><a-.>` will insert all selections joined by space instead of only

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.

commit 90db664635013f6e857ec696403f2164032410a8 introduced logic
to handle the case where the mode had been removed, but did not
get rid of the assert.

Terminals that support CSI u escape codes (like iTerm2, Kitty and foot)
allow us to map <s-space> independently of <space>.
Users expect that <s-space> inputs a space character; make it so.

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
|
|
In normal mode, the mode line contains "1 sel" or "n sels (k)" when n > 1,
whereas in insert mode, it contains "n sels (k)" even for n == 1. Change
the contents in insert mode to match normal mode.
|
|
|
|
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.

prove too cumbersome.

This can be an issue with NextKey that now does not have a static
mode name.
|
|
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 #3849 Again

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 aab0be529f77f3a8e86185a030838e6d547d0286.
|
|
Previously we would only auto-insert if the current token had some
text, but this breaks auto-selection of the first match.
Fixes #3849
|
|
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.
|
|
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.

The prompt and autocomplete normally wait for `idle_timeout` before showing
suggestions, however commands like `g`, `v`, or the lead-key show Clippy
instantly.
This fixes the issue by making `on_next_key_with_autoinfo()` wait for
`idle_timeout` before displaying suggestions.

The UI now can send a 'Scroll' key, whose value is the scrolling
amount encoded as a signed integer. This replaces the MouseWheelUp
and MouseWheelDown keys.
The NCursesUI now has a ncurses_wheel_scroll_amount ui_option that
controls that amount, it can be negative to swap scrolling direction.
