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.

== Declaration
|
|
|
|
A 'face' determines how text is displayed, it has a foreground
|
|
color, a background color, and some attributes. The value of a face has the
|
|
following format:
|
|
|
|
-----------------------------------------------------------
|
|
[fg_color][,bg_color[,underline_color]][+attributes][@base]
|
|
-----------------------------------------------------------
|
|
|
|
'fg_color', 'bg_color', 'underline_color'::
|
|
a color whose value can be expressed in the following formats:
|
|
*black*, *red*, *green*, *yellow*, *blue*, *magenta*, *cyan*, *white*:::
|
|
*bright-black*, *bright-red*, *bright-green*, *bright-yellow*:::
|
|
*bright-blue*, *bright-magenta*, *bright-cyan*, *bright-white*:::
|
|
a named color
|
|
*default*:::
|
|
keep the existing color
|
|
*rgb:RRGGBB*:::
|
|
hexadecimal value
|
|
*rgba:RRGGBBAA*:::
|
|
hexadecimal value
|
|
if unspecified or empty, *default* is used.
|
|
Alpha values are used to blend the face onto either its base or the existing
|
|
color. For technical reasons alpha values must be >16 if specified.
|
|
|
|
'attributes'::
|
|
string whose individual letters set an attribute:
|
|
*u*:::
|
|
underline
|
|
*c*:::
|
|
curly underline, takes precedence over underline if both are
|
|
specified
|
|
*r*:::
|
|
reverse
|
|
*b*:::
|
|
bold
|
|
*B*:::
|
|
blink
|
|
*d*:::
|
|
dim
|
|
*i*:::
|
|
italic
|
|
*s*:::
|
|
strikethrough
|
|
*F*:::
|
|
final, override the previous face instead of merging with it,
|
|
and this face will only be replaced if another face with
|
|
the final attribute is applied
|
|
*f*:::
|
|
final foreground, as final but only applies to face's
|
|
foreground color
|
|
*g*:::
|
|
final background, as final but only applies to face's
|
|
background color
|
|
*a*:::
|
|
final attributes, as final but only applies to face's
|
|
attributes
|
|
|
|
'base'::
|
|
The base face on which this face applies, which can be any face name,
|
|
as long as no cycle is introduced. A face can reference itself, in
|
|
which case it will apply on top of the parent scope version.
|
|
|
|

== Markup strings
|
|
|
|
In certain contexts, Kakoune can take a markup string, which is a string
|
|
containing formatting information. In these strings, the {facename}
|
|
syntax will enable the face facename until another face gets activated,
|
|
or the end of the string is reached.
|
|
|
|
For example, the following command displays the text "default" in the
|
|
Default face, and "error" in the Error face:
|
|
|
|
----
|
|
echo -markup 'default {Error}error{Default} default'
|
|
----
|
|
|
|
Inside a markup string, a literal `{` character is written `\{`, and a
|
|
literal backslash (`\`) that precedes a '{' character is escaped as well
|
|
(`\\`).
|
|
|
|
The `{\}` string disables markup processing for the rest of the line,
|
|
and can be used to avoid having to escape text that might be mistaken
|
|
for markup instructions.
|
|
|
|
For example this will prevent any '{' in the current buffer name from
|
|
being incorrectly interpreted as markup instruction.
|
|
|
|
----
|
|
echo -markup "{Information}name:{\} %val{bufname}"
|
