Test::Tabs - check the presence of tabs in your project
use Test::Tabs tests => 1;
tabs_ok('lib/Module.pm', 'Module is indented sanely');
all_perl_files_ok( @mydirs );
This module scans your project/distribution for any perl files (scripts, modules, etc) for the presence of tabs.
In particular, it checks that all indentation is done using tabs, not spaces; alignment is done via spaces, not tabs; indentation levels never jump up (e.g. going from 1 tab indent to 3 tab indent without an intervening 2 tab indent); and there is no trailing whitespace on any line (though lines may consist entirely of whitespace).
Comment lines and pod are ignored. (A future version may also ignore heredocs.)
A trailing comment ##WS can be used to ignore all whitespace rules for that line. ## no Test::Tabs can be used to begin ignoring whitespace rules for all following lines until ## use Test::Tabs is seen. ## skip Test::Tabs tells Test::Tabs to skip the current file, but it must be used before the first whitespace rule violation.
## no Test::Tabs
## use Test::Tabs
## skip Test::Tabs
all_perl_files_ok( @directories )
Applies tabs_ok() to all perl files found in @directories recursively. If no @directories are 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, *.pm, *.psgi, *.t, or a file starting with #!...perl.
tabs_ok( $file, $text )
Run a tab check on $file. For a module, either the path (lib/My/Module.pm) or the package name (My::Module) can be used.
$text is the optional test name.
