Colored and styled underlines
|
|
================================
|
|
|
|
|kitty| supports colored and styled (wavy) underlines. This is of particular
|
|
use in terminal editors such as vim and emacs to display red, wavy underlines
|
|
under mis-spelled words and/or syntax errors. This is done by re-purposing some
|
|
SGR escape codes that are not used in modern terminals (`CSI codes
|
|
<https://en.wikipedia.org/wiki/ANSI_escape_code#CSI_(Control_Sequence_Introducer)_sequences>`_)
|
|
|
|
To set the underline style::
|
|
|
|
<ESC>[4:0m # this is no underline
|
|
<ESC>[4:1m # this is a straight underline
|
|
<ESC>[4:2m # this is a double underline
|
|
<ESC>[4:3m # this is a curly underline
|
|
<ESC>[4:4m # this is a dotted underline (not implemented in kitty)
|
|
<ESC>[4:5m # this is a dashed underline (not implemented in kitty)
|
|
<ESC>[4m # this is a straight underline (for backwards compat)
|
|
<ESC>[24m # this is no underline (for backwards compat)
|
|
|
|
To set the underline color (this is reserved and as far as I can tell not actually used for anything)::
|
|
|
|
<ESC>[58...m
|
|
|
|
This works exactly like the codes ``38, 48`` that are used to set foreground and
|
|
background color respectively.
|
|
|
|
To reset the underline color (also previously reserved and unused)::
|
|
|
|
<ESC>[59m
|
|
|
|
The underline color must remain the same under reverse video, if it has a
|
|
color, if not, it should follow the foreground color.
|
|
|
|
To detect support for this feature in a terminal emulator, query the terminfo database
|
|
for the ``Su`` boolean capability.
