(fwd) ncurses vs slang

Wed Oct 23 09:42:17 UTC 2002

Hi!

These mails from mutt-dev at dbnet.net can be related to

ncurses 5.2 turns off keypad under heavy load on xterm.  Check if 
anything can be done about it.

See last mail in link and thanks to Andrew W. Nosenko for
sending these mails to me.

Hi all,

I was just wondering if there was any advantage to using slang over
ncurses.

"slang" is shorter than "ncurses" -
but you have to add "--with-slang"
when configuring mutt for compilation.

You have been getting worse and worse lately, Sven -- are you perhaps
getting [too] old or something...? :-)

    Better use the list's prefered address: mutt-dev at mutt.org

    I haven't precise timings, but I once noticed Slang was generally
a little bit faster at redraws, scrolling, and such things.

most of that was because slang doesn't pay attention to the padding specified
in the vt100 entry (the numbers in <>):
