-Test::EOL - Check the correct line endings in your project
=head1 SYNOPSIS
-C<Test::EOL> lets you check the presence of windows line endings in your
-perl code. It
-report its results in standard C<Test::Simple> fashion:
+C<Test::EOL> lets you check for the presence of trailing whitespace and/or
+windows line endings in your perl code. It reports its results in standard
+C<Test::Simple> fashion:
use Test::EOL tests => 1;
eol_unix_ok( 'lib/Module.pm', 'Module is ^M free');
+and to add checks for trailing whitespace:
+
+ use Test::EOL tests => 1;
+ eol_unix_ok( 'lib/Module.pm', 'Module is ^M and trailing whitespace free', { trailing_whitespace => 1 });
+
Module authors can include the following in a t/eol.t and have C<Test::EOL>
automatically find and check all perl files in a module distribution:
use Test::EOL;
all_perl_files_ok( @mydirs );
+and if authors would like to check for trailing whitespace:
+
+ use Test::EOL;
+ all_perl_files_ok({ trailing_whitespace => 1 });
+
+or
+
+ use Test::EOL;
+ all_perl_files_ok({ trailing_whitespace => 1 }, @mydirs );
+
+or
+
+ use Test::More;
+ use Test::EOL 'no_test';
+ all_perl_files_ok();
+ done_testing;
+
=head1 DESCRIPTION
This module scans your project/distribution for any perl files (scripts,
A list of functions that can be exported. You can delete this section
if you don't export anything, such as for a purely object-oriented module.
-=head1 FUNCTIONS
+=func all_perl_files_ok
-=head2 all_perl_files_ok( [ @directories ] )
+ all_perl_files_ok( [ \%options ], [ @directories ] )
Applies C<eol_unix_ok()> to all perl files found in C<@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
+directories). If no <@directories> is given, the starting point is the current
+working directory, as tests are usually run from the top directory in a typical
+CPAN distribution. A perl file is *.pl or *.pm or *.pod or *.t or a file starting
with C<#!...perl>
-If the test plan is defined:
+Valid C<\%options> currently are:
- use Test::EOL tests => 3;
- all_perl_files_ok();
+=over
-the total number of files tested must be specified.
+=item * trailing_whitespace
-=head2 eol_unix_ok( $file [, $text] )
+By default Test::EOL only looks for Windows (CR/LF) line-endings. Set this
+to true to raise errors if any kind of trailing whitespace is present in
+the file.
-Run a unix EOL check on C<$file>. For a module, the path (lib/My/Module.pm) or the
-name (My::Module) can be both used.
+=item * all_reasons
+
+Normally Test::EOL reports only the first error in every file (given that
+a text file originated on Windows will fail every single line). Set this
+a true value to register a test failure for every line with an error.

-Otherwise please report any bugs or feature requests to
-C<bug-test-eol at rt.cpan.org>, or through the web interface at
-L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Test-EOL>.
-I will be notified, and then you'll automatically be notified of progress on
-your bug as I make changes.
+Run a unix EOL check on C<$file>. For a module, the path (lib/My/Module.pm) or the
+name (My::Module) can be both used. C<$text> is the diagnostic label emited after
+the C<ok>/C<not ok> TAP output. C<\%options> takes the same values as described in
+L</all_perl_files_ok>.
