All,
it is my understanding (and please correct me) that the cterm has no
support for italics being rendered in an italic font (or emitting the
appropriate escape sequence), i.e.
highlight LineNr cterm=italic
is rendered in different colors instead of using an italic font. Xterm
has support for italics for both bitmapped and rendered fonts. To test,
printf '\033[1mBold\033[22m off\n'
printf '\033[2mFaint\033[22m off\n'
printf '\033[3mItalics\033[23m off\n'
printf '\033[4mUnderline\033[24m off\n'
printf '\033[5mBlink\033[25m off\n'
printf '\033[7mInverse\033[27m off\n'
printf '\033[8mInvisible\033[28m off\n'
printf '\033[9mStrikethrough\033[29m off\n'
printf '\033[21mDoubly Underlined\033[24m off\n'
For way too long I use an ugly workaround to have the line numbers in italics.
I fake them in vim with "highlight LineNr cterm=underline" and force
xterm to replace underline with italic (with the +ulit option). But that
loses the underline attribute for other items.
Would the developers be willing to implement support for cterm=italic?
While you're at it, the faint, strikethrough and doubly underlined
would be a welcome addition as well. One more value-add over em*cs :-)
Regards,
Jens
