Change the logic of open line commands so that if a selection lies
on the end of line character of the line from which we open a new
line, that selection does not move.
If we have two clients, A and B, with B's cursor on the eol character
of line L, and A hits `o` while on line L, B's cursor should stay
on the same (logical) line. Previous behaviour would make B's cursor
jump on the newly inserted line.
Selection merging is necessary if we want X to work nicely when we are
on EOL (jumping to next line is as nice as it could be, and we are much
more often on EOL nowadays).
Some iterators were refering to to their view with a const ref, this
was making them non-copiable. Change those const ref into const pointers
in order to fix that.
This change displays command-line options in grid format. Each
parameter is indented with two spaces and then padded to maintain
vertical alignment of each description.
I think the visual spacing makes the options much easier to
read. This is particularly important for people new to Kakoune who
use `-help` as a way to become familiar with the program.
Various places in Kakoune code used to modify selections so that
cursors would not lie on an end of line. Remove those to increase
Kakoune's consistency and simplicity.
Now that end of lines are highlighted separately, they should not
be handled specially in most commands.
When on an end of line, certain behaviours can be surprising, for
example delete will join the following line (which makes sense, and
is consistent, but hard to predict if we do not know the cursor is
on and end of line).
As Kakoune is moving more and more towards treating end of lines
as any other character, making it clear when the cursor lies on
them seems like a good way to reduce surprise.
Avoiding end of line is a behaviour we avoid (pun intended) more and more
in Kakoune source code, now that end of lines are regularly selected, it
makes no sense to just to next line when last modification lies on an EOL
(and it probably did not make much sense back when that code was written).
This reverts commit 55621fb4cc.
This should not be necessary as :exec/eval already save those registers
and reset them by default, and it breaks the ability to use those
registers during an eval/exec (as the commands behave differently)
There does not seem to be any reasonable use cases of not collapsing
jumps when the input is not comming from the user. Always collapse
them.
It could make sense to move jump collapsing out of context_wrap as
in general any action not comming directly from the user should
collapse them, at the moment a comment or mapping will not collapse
jumps, which is unfortunate.
