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 $_'
