Text::Tabs -- expand and unexpand tabs per the unix expand(1) and unexpand(1)
use Text::Tabs;
$tabstop = 4; # default = 8
@lines_without_tabs = expand(@lines_with_tabs);
@lines_with_tabs = unexpand(@lines_without_tabs);
Text::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 (just like unexpand -a
). Invisible compression with plain ASCII!
#!perl
# unexpand -a
use Text::Tabs;
while (<>) {
print unexpand $_;
}
Instead of the expand
comand, use:
perl -MText::Tabs -n -e 'print expand $_'
Instead of the unexpand -a
command, use:
perl -MText::Tabs -n -e 'print unexpand $_'
