=head1 NAME
Run::Parts::Perl - Pure Perl implementation of Debian's run-parts tool
=head1 VERSION
version 0.09
=head1 SYNOPSIS
Pure Perl reimplementation of basic functionality of Debian's
L<run-parts(8)> tool.
L<run-parts(8)> runs all the executable files named within constraints
described below, found in the given directory. Other files and
directories are silently ignored.
Additionally it can just print the names of the all matching files
(not limited to executables, but ignores blacklisted files like
e.g. backup files), but don't actually run them.
This is useful when functionality or configuration is split over
multiple files in one directory.
This module is not thought to be used directly and its interface may
change. See L<Run::Parts> for a stable user interface.
=head1 FILE NAME CONSTRAINTS
On unix-ish operating systems, the file name (but not the path) must
match ^[-A-Za-z0-9_]+$, i.e. may not contain a dot.
On dos-ish operating systems, the file name without suffix must match
^[-A-Za-z0-9_]+$, i.e. may not contain a dot. The suffix may contain
alphanumeric characters and is not mandatory. The full regular
expression the file name including the suffix must match is
^[-A-Za-z0-9_]+(\.[A-Za-z0-9]+)?$.
Debian's L<run-parts(8)> tool also offers to use alternative regular
expressions as file name constraints. This is not yet implemented in
L<Run::Parts::Perl>.
=head1 METHODS
=head2 new (Constructor)
Creates a new L<Run::Parts> object. Takes one parameter, the directory
on which run-parts should work.
=head2 run_parts_command
Executes the given action with the given parameters
=head2 list
Lists all relevant files in the given directory. Equivalent to
"run-parts --list". Returns an array.
=head2 test
Lists all relevant executables in the given directory. Equivalent to
"run-parts --tests". Returns an array.
=head2 run
Executes all relevant executables in the given directory. Equivalent to
"run-parts --tests". Returns an array.
=head1 INTERNAL FUNCTIONS
=head2 dosish
Returns true if ran on a dos-ish platform, i.e. MS-DOS, Windows or
OS/2.
=head1 SEE ALSO
L<Run::Parts>, L<run-parts(8)>
=head1 BUGS
Please report any bugs or feature requests to C<bug-run-parts at
rt.cpan.org>, or through the web interface at
L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Run-Parts>. I will
be notified, and then you'll automatically be notified of progress on
your bug as I make changes.
