Text::Tabs - expand and unexpand tabs like unix expand |
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.
The following are exported:
$tabstop variable controls how many column positions apart each
tabstop is. The default is 8.
Please note that local($tabstop) doesn't do the right thing and if you want
to use local to override $tabstop, you need to use
local($Text::Tabs::tabstop).
#!perl # unexpand -a use Text::Tabs;
while (<>) {
print unexpand $_;
}
Instead of the expand command, use:
perl -MText::Tabs -n -e 'print expand $_'
Instead of the unexpand -a command, use:
perl -MText::Tabs -n -e 'print unexpand $_'
This module comes in two flavors: one for modern perls (5.10 and above)
and one for ancient obsolete perls. The version for modern perls has
support for Unicode. The version for old perls does not. You can tell
which version you have installed by looking at $Text::Tabs::SUBVERSION:
it is old for obsolete perls and modern for current perls.
This man page is for the version for obsolete perls and so that's probably what you've got.
