Some plugins (*cough* kak-lsp) and help texts tend to have immensely long content
in a single line. This generates info boxes that span the entire terminal width.
This is made especially worse on widescreen monitors or at small text size.
This grants user control over how wide these boxes are.
I deliberately avoid pushing this change to `kak-lsp` because it's not the only
plugin that this could help--see the `hook` help text for an example of this
problem in vanilla Kakoune. I would also suggest that since this is a rendering
concern, it be handled by the terminal rendering logic.
Originally the page said:
> No other escaping takes place in balanced strings.
...but in the course of a general readability rewrite (56287da) this was
changed to:
> Characters may be escaped in the same manner as those for quoted strings.
...which is not actually true; probably this change made it in because there
were a lot of good changes in those commits and we didn't read them all closely
enough.
Now the documentation is correct again, and I've added some examples covering
the problems people occasionally ask about (see #2760).
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
This wording was valid for an old version of that patch that foolishly
add a switch to "map" to allow recording history. Happily we found
a better solution. Now commands inside user mappings never add to
prompt history (unless you use "set-register"), so be clear about that.
So far they have only been talked about in source code
(HistoryRegister), not in documentation.
Let's give them an official name so users can find them better;
"prompt history register" seems better than "history register" since
the former gives more context. OTOH, in future other registers (like @)
could grow into history registers, so I'm not sure.
State that the history registers are only changed by _interactive_
prompts; that's not quite true yet for user modes but I'll push a
separate fix for that.
We often use the pattern «map global normal ": foo"». The space
after the colon is unnecessary since execution of the mapping won't
add to history anyway, since 217dd6a1d (Disable history when executing
maps, 2015-11-10).
With the parent commit, the space is no longer necessary for user
mappings, so there is no reason to continue the cargo-cult.
Remove the space from mappings to set a good example.
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.

`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
Cross-reference the "completers" option, and explain how filtering works.

For the "completions" option type, the documentation states that |
and \ need to be escaped as \| and \\.
The same parser is for other option types that are lists-of-tuples:
range-specs and line-specs, so they need escaping too. Document that.
Only their last element can contain arbitrary data, so range-specs
and line-specs could work without escaping if we tweaked the parser.
The prologue led some users to believe the implementation was compliant with ECMAScript let alone some differences (who *are* documented at the end of the page).
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
same as `default,default,red+u`
Fixes#4138
Synchronized output does not work well with various terminals
(including the linux console). It should also be unnecessary when
not going through a slow link.
This will eventually be removed if it is not proven to be useful
to some users.
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)"
}
```
* Polish some grammar in places.
* Correct some capitalization nitpicks.
* Use "newline" rather than "line feed", which tends to be more common
in Kakoune's documentation thusfar.
I rephrased some sections, as some of them read a little odd.
* Zero width assertions
* Consistently use "subject's beginning" instead of "subject begin",
it reads better.
* Improve the flow of the word boundary descriptions.
* Modifiers
* Improve phrasing to emphasize the linear nature of their usage and
remove a double negative.
* Use `.` instead of "dot", since that aids in searching through the
page for things talking about the dot character.
* Compatibility
* Use asciidoc syntax for the link to the ECMA-262 standard.
* Use better punctuation on the point about escapes.
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 "~").
