Test::NoTabs(3) Check the presence of tabs in your project


"Test::NoTabs" lets you check the presence of tabs in your perl code. It report its results in standard "Test::Simple" fashion:

use Test::NoTabs tests => 1;
notabs_ok( 'lib/Module.pm', 'Module is tab free');

Module authors can include the following in a t/notabs.t and have "Test::NoTabs" automatically find and check all perl files in a module distribution:

  use Test::NoTabs;


  use Test::NoTabs;
  all_perl_files_ok( @mydirs );


This module scans your project/distribution for any perl files (scripts, modules, etc) for the presence of tabs.


all_perl_files_ok( [ @directories ] )

Applies "notabs_ok()" to all perl files found in @directories (and sub directories). If no <@directories> is given, the starting point is one level above the current running script, that should cover all the files of a typical CPAN distribution. A perl file is *.pl or *.pm or *.t or a file starting with "#!...perl"

If the test plan is defined:

  use Test::NoTabs tests => 3;

the total number of files tested must be specified.

notabs_ok( $file [, $text] )

Run a tab check on $file. For a module, the path (lib/My/Module.pm) or the name (My::Module) can be both used.
