NAME

Filter::Include - Emulate the behaviour of the C preprocessor's #include

SYNOPSIS

use Filter::Include;

include Foo::Bar;
include "somefile.pl";

## or

#include Some::Class
#include "little/library.pl"

DESCRIPTION

Take the #include preproccesor directive from C, stir in some perl semantics and we have this module. Only one keyword is used, include, which is really just a processor directive for the filter, which indicates the file to be included. The argument supplied to include will be handled like it would by require and use with the traversing of @INC and the populating of %INC and the like.

#include

For those not clued in on what C's #include processor directive does this section shall explain briefly its purpose, and why it's being emulated here.

What

When the C preprocessor sees the #include directive, it will include the given file straight into the source. It is syntax-checked and dumped where #include previously stood, so becomes part of the source of the given file when it is compiled.

Why

Basically the 'why' of this module is that I'd seen several requests on Perl Monks, the one which really inspired this was

http://www.perlmonks.org/index.pl?node_id=254283

So I figured other people that haven't posted to Perl Monks may want it, so here it is in all its filtering glory.

Changes

1.2

• Fixed 2 bugs - forgot to reverse @dirs in find_module_file and _isfh now checks if an object can getlines (not can which is silly).

1.1

• Upgraded to a more respectable version number

• Added a more robust check for the existence of a filehandle

• Added tests for the coderef-type magic in @INC when performing a bareword include.

• Added Changes section in POD
