Previously it would result in a stray single-character selection at the
beginning of the input text.
For example:
[abcabc] -> split on 'a' -> [a][bc]a[bc]
or
[foobarfoobar] -> split on 'foo' -> [f]oo[bar]foo[bar]
Note that this behavior was not occuring if the input text was at the
beginning of the buffer

Commit 933e4a599 (Load buffer in command line order, 2022-12-06)
introduced a regression: the command
$ kak /boot/grub/grub.cfg
Fatal error: no such buffer '/boot/grub/grub.cfg'
quits with no indication of the underlying error.
Prior to 933e4a599, it would open the *scratch* buffer instead,
and show an error in the status line, pointing to the debug buffer,
which would contain:
error while opening file '/boot/grub/grub.cfg':
/boot/grub/grub.cfg: Permission denied
Let's fix this scenario by matching the old behavior.
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.
This commit fixes a bug in Buffer::advance where it would first access
m_lines[-1], and then check whether or not that access would have
segfaulted. This commit moves the check to before the segfault would
occur.
Using BufferIterator adds overhead, but we know that DisplayAtoms
cannot span multiple buffer lines and hence we can directly iterate
using char pointers.
Each draft context gets its own private copy of the selections.
Any selection changes will be thrown away when the draft context
is disposed. Since selection-undo is only supported as top-level
command, it can never be used inside a draft context, so let's stop
recording it.
No functional change.
Calculating the length of an atom means we need to decode every
codepoint and compute its column width. This can prove quite expensive
in trim_from as we can have full buffer lines, so on buffer with long
lines we might have to go through megabytes of undisplayed data.
Pass the first buffer on the the command line explicitely to client
creation. This ensure the buffer list matches the command line, which
makes buffer-next/buffer-previous a bit more useful.
Fixes#2705
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.
Fixes#4779
Before, sed would add quotes to every line of the single multiline argument,
causing the final quoted argument to "split ... command" or screen to contain
unquoted newlines such as this (from kakoune-cr):
tell application "iTerm"
tell current session of current window
tell (split vertically with same profile command "env PATH='...' 'sh' '-c' ''
' export KAKOUNE_SESSION=$1'
' export KAKOUNE_CLIENT=$2'
' shift 3'
''
' [ $# = 0 ] && set \"$SHELL\"'
''
' \"sh\"'
' ' '--' '51909' 'client0' 'terminal' ") to select
end tell
end tell
Instead of using sed to do this which operates on single lines at a time, simply
use printf to insert ' quotes before and after the entire argument.
Comparing iterators between buffers should never happen, and the
only place we did was with default constructed BufferIterator which
we replace by casting the iterator to bool.
This should improve performance on iterator heavy code.
