Text::Tabs - expand and unexpand tabs like 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 most of what the unix utilities expand(1) and unexpand(1) do. Given a line with tabs in it, expand
replaces those tabs with the appropriate number of spaces. Given a line with or without tabs in it, unexpand
adds tabs when it can save bytes by doing so, like the unexpand -a
command.
Unlike the old unix utilities, this module correctly accounts for any Unicode combining characters (such as diacriticals) that may occur in each line for both expansion and unexpansion. These are overstrike characters that do not increment the logical position. Make sure you have the appropriate Unicode settings enabled.
