If the local client was quitted during its creation (using -e quit
for example), we could have been accessing a null pointer afterwards.
Make the rest of the code aware that local_client might be null.
Shifted function keys are not well standardized around terminals,
Shift F(N) usually returns F(X) + N, with X=12 on xterm, X=10 on
rxvt-unicode... Default to X=12 and make it configuable through
the ncurses_shift_function_key ui_option.
This fixes what #1898 tried to.
Because keyboard layouts vary, the shift-modifier `<s-…>` is only supported
for special keys (like `<up>` and `<home>`) and for ASCII lowercase where
we assume the shift-modifier just produces the matching uppercase character.
Even that's not universally true, since in Turkish `i` and `I` are not an
uppercase/lowercase pair, but Kakoune's default keyboard mappings already
assume en-US mappings for mnemonic purposes.
Mappings of the form `<s-x>` are normalized to `<X>` when `x` is an ASCII
character. `<backtab>` is removed, since we can now say `<s-tab>`.
set-face now takes a scope argument, and faces can be overridden on
a buffer or window basis.
colorscheme apply on global scope, which should be good enough for
now.
Fixes#1411
Schedule it for later, when we get "idle". It currently can lead to
crashed because after the callback, the current mode might be different,
leading to a crash when doing the ModeChange hook call.
Session/Client/User modes names are now requiered to be "identifiers"
they must be in [a-zA-Z0-9_-]. Option names are the same except they
do not allow '-' as they need to be made available through the env vars
and '-' is not supported there.
Fixes#1946
In the end, % is not that painful to work with as its only set seldomly,
and we usually dont need to use expansion at the same time. Moreover, it
just requires a single \ to be escaped.
Fixes#1562
When Kakoune forked the sever to background, the newly converted
to client process (the original client/server process) was not
preserving its previous client name.
Letting any character to be escaped is error prone as it looks like
\l could mean [:lower:] (as it used to with boost) when it only means
literal l.
Fix the haskell.kak file as well.
Fixes#1945
As the computation of word boundary matches is separate from the
actual subsequence matching, we sometimes have candidate that match
as a single word while still having multiple word boundary matches.
For example, with query "expresins", candidate "expressionism's"
will match as single word ("expressins" is a subsequence of
"expressionism"), and will have two word boundaries match (it does
match the last "s", which is considered as a separate word).
This should not be taken into account when compared against
candidate "expresions", which should be considered a better
match.
Fixes#1925
Reference highlighters allow for potential mutual recursion between
highlighters. This is usually fine, but if the recursion happens on
the same buffer range, it means we will recurse infinitely.
Fixes#1920
Pressing Y or N will set the buffer (or window, if it is set at that
scope) autoreload option to the corresponding value, avoiding infinite
loops where a file getting constantly modified prevents the user from
using Kakoune.
To allow more general look arounds out of the actual search range,
pass a second range (the actual subject). This allows us to remove
various flags such as PrevAvailable or NotBeginOfSubject, which are
now easy to check from the subject range.
Fixes#1902
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.
Aliases are considered again in command name completion, but only
if they are more than 3 charactes long. This should prevent cluttering
with aliases while still letting long ones being completed.
The keymap mode was passed to on_next_key_with_autoinfo, which
means the mapping was applied directly by the InputHandler.
That led to the first key being interpretted as a mapping, then
all following keys being executed normally, as if typed in the
parent mode of the user mapping.
The debug buffer is a bit special as lots of events might mutate it,
permitting it to be modified leads to some buggy behaviour:
For example, `pipe` uses a ForwardChangeTracker to track buffer
changes, but when applied on a debug buffer with the profile flag
on, each shell execution will trigger an additional modification
of the buffer while applying the changes, leading to an assertion
failing as changes might not be happening in a forward way anymore.
Trying to modify a debug buffer will now raise an error immediatly.
forward (which controls if we are compling for forward or backward
matching) is always statically known, and compilation will first
compile forward, then backward (if needed), so by having separate
compiled function we get rid of runtime branches.
