Text::Tabs(3) Perl Programmers Reference Guide Text::Tabs(3)NAMEText::Tabs-- expand and unexpand tabs per the unix
expand(1) and unexpand(1)SYNOPSIS
use Text::Tabs;
$tabstop = 4; @lines_without_tabs =
expand(@lines_with_tabs); @lines_with_tabs =
unexpand(@lines_without_tabs);
DESCRIPTIONText::Tabs does about what the unix utilities expand(1)
and unexpand(1) do. Given a line with tabs in it, expand
will replace the tabs with the appropriate number of
spaces. Given a line with or without tabs in it, unexpand
will add tabs when it can save bytes by doing so.
Invisible compression with plain ascii!
BUGS
expand doesn't handle newlines very quickly -- do not feed
it an entire document in one string. Instead feed it an
array of lines.
