Terminal control/Inverse video is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
The task is to display a word in inverse video followed by a word in normal video.
Tcl
This only works on Unix terminals. <lang tcl># Get how the terminal wants to do things... set videoSeq(reverse) [exec tput rev] set videoSeq(normal) [exec tput rmso] proc reverseVideo str {
global videoSeq
return "$videoSeq(reverse)${str}$videoSeq(normal)"
}
- The things to print
set inReverse "foo" set inNormal "bar"
- Print those words
puts "[reverseVideo $inReverse] $inNormal"</lang>
