## Terminal::ANSI This is a library of ANSI escape sequences. ### Example use Terminal::ANSI; save-screen; clear-screen; home; hide-cursor; sub scroll($row,$col = 1, $height = 7) { print-at $row,$col, "━" x 20; print-at $row + $height,$col, "━" x 20; my $on = $row; for 20000, 19999 ... 0 { atomically { set-scroll-region($row + 1,$row + $height - 1); scroll-up if $on >= $row + $height - 1; print-at ++$on min $row + $height - 1, $col, "counting down..$_"; } } } my $p1 = start scroll(2); my $p2 = start scroll(12,10,10); my $p3 = start scroll(24); await Promise.allof($p1,$p2,$p3); sleep 1; reset-scroll-region; show-cursor; restore-screen; See the [eg/](https://git.sr.ht/~bduggan/raku-terminal-ansi/tree/master/eg) directory for more examples. ## Description The functions in this module print ANSI escape sequences to stdout. There are functions for cursor movement, scroll regions, colors, and other screen functionality. There aren't functions for any of the esoteric escape codes. The `atomically` function suppresses printing, and instead concatenates the output and emits the entire line at the end. This is helpful for multi-threaded situations, where the output of several functions needs to be in one piece. There is also an OO interface (see the examples). ## Author Brian Duggan ## TODO More documentation.
