# NAME CatalystX::ASP - PerlScript/ASP on Catalyst # VERSION version 1.00 # INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install # SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc CatalystX::ASP # SYNOPSIS package MyApp; use Moose; use Catalyst; extends 'Catalyst'; with 'CatalystX::ASP::Role'; 1; # DESCRIPTION CatalystX::ASP is a plugin for Catalyst to support ASP (PerlScript). This is largely based off of Joshua Chamas's [Apache::ASP](https://metacpan.org/pod/Apache::ASP), as the application I've been working with was written for [Apache::ASP](https://metacpan.org/pod/Apache::ASP). Thus, this was designed to be almost a drop-in replacement. However, there were many features that I chose not to implement. This plugin basically creates a Catalyst View which can process ASP scripts. As an added bonus, a simple [CatalystX::ASP::Role](https://metacpan.org/pod/CatalystX::ASP::Role) can be included to allow for automatical processing of files with _.asp_ extension in the application _root_ directory. Just to be clear, the [Parser](https://metacpan.org/pod/CatalystX::ASP::Parser) is almost totally ripped off of Joshua Chamas's parser in [Apache::ASP](https://metacpan.org/pod/Apache::ASP). Similarly with the [Compiler](https://metacpan.org/pod/CatalystX::ASP::Compiler) and [GlobalASA](https://metacpan.org/pod/CatalystX::ASP::GlobalASA). However, the other components are a reimplementations. # CONFIGURATION You can configure CatalystX::ASP in Catalyst under the `CatalystX::ASP` section of the configuration __PACKAGE__->config('CatalystX::ASP' => { Global => 'lib', GlobalPackage => 'MyApp', IncludesDir => 'templates', MailHost => 'localhost', MailFrom => 'myapp@localhost', XMLSubsMatch => '(?:myapp):\w+', Debug => 0, }): The following documentation is also plagiarized from Joshau Chamas. - Global Global is the nerve center of an Apache::ASP application, in which the global.asa may reside defining the web application's event handlers. Includes, specified with `<!--#include file=somefile.inc-->` or `$Response->Include()` syntax, may also be in this directory, please see section on includes for more information. - GlobalPackage Perl package namespace that all scripts, includes, & global.asa events are compiled into. By default, GlobalPackage is some obscure name that is uniquely generated from the file path of the Global directory, and global.asa file. The use of explicitly naming the GlobalPackage is to allow scripts access to globals and subs defined in a perl module that is included with commands like: __PACKAGE__->config('CatalystX::ASP') ->GlobalPackage('MyApp'); - IncludesDir No default. If set, this directory will also be used to look for includes when compiling scripts. By default the directory the script is in, and the Global directory are checked for includes. This extension was added so that includes could be easily shared between ASP applications, whereas placing includes in the Global directory only allows sharing between scripts in an application. __PACKAGE__->config('CatalystX::ASP') ->IncludesDir('.'); Also, multiple includes directories may be set: __PACKAGE__->config('CatalystX::ASP') ->IncludesDir(['../shared', '/usr/local/asp/shared']); Using IncludesDir in this way creates an includes search path that would look like `.`, `Global`, `../shared`, `/usr/local/asp/shared`. The current directory of the executing script is checked first whenever an include is specified, then the `Global` directory in which the `global.asa` resides, and finally the `IncludesDir` setting. - MailHost The mail host is the SMTP server that the below Mail\* config directives will use when sending their emails. By default [Net::SMTP](https://metacpan.org/pod/Net::SMTP) uses SMTP mail hosts configured in [Net::Config](https://metacpan.org/pod/Net::Config), which is set up at install time, but this setting can be used to override this config. The mail hosts specified in the Net::Config file will be used as backup SMTP servers to the `MailHost` specified here, should this primary server not be working. __PACKAGE__->config('CatalystX::ASP') ->MailHost('smtp.yourdomain.com.foobar') - MailFrom No default. Set this to specify the default mail address placed in the `From:` mail header for the `$Server->Mail()` API extension __PACKAGE__->config('CatalystX::ASP') ->MailFrom('youremail@yourdomain.com.foobar') - XMLSubsMatch Default is not defined. Set to some regexp pattern that will match all XML and HTML tags that you want to have perl subroutines handle. The is ["XMLSubs" in Apache::ASP](https://metacpan.org/pod/Apache::ASP#XMLSubs)'s custom tag technology ported to CatalystX::ASP, and can be used to create powerful extensions to your XML and HTML rendering. Please see XML/XSLT section for instructions on its use. __PACKAGE__->config('CatalystX::ASP') ->XMLSubsMatch('my:[\w\-]+') - Debug Currently only a placeholder. Only effect is to turn on stacktrace on `__DIE__` signal. # OBJECTS The beauty of the ASP Object Model is that it takes the burden of CGI and Session Management off the developer, and puts them in objects accessible from any ASP script and include. For the perl programmer, treat these objects as globals accessible from anywhere in your ASP application. The CatalystX::ASP object model supports the following: Object Function ------ -------- $Session - user session state $Response - output to browser $Request - input from browser $Application - application state $Server - general methods These objects, and their methods are further defined in their respective pod. - [CatalystX::ASP::Session](https://metacpan.org/pod/CatalystX::ASP::Session) - [CatalystX::ASP::Response](https://metacpan.org/pod/CatalystX::ASP::Response) - [CatalystX::ASP::Request](https://metacpan.org/pod/CatalystX::ASP::Request) - [CatalystX::ASP::Application](https://metacpan.org/pod/CatalystX::ASP::Application) - [CatalystX::ASP::Server](https://metacpan.org/pod/CatalystX::ASP::Server) If you would like to define your own global objects for use in your scripts and includes, you can initialize them in the `global.asa` `Script_OnStart` like: use vars qw( $Form $App ); # declare globals sub Script_OnStart { $App = MyApp->new; # init $App object $Form = $Request->Form; # alias form data } In this way you can create site wide application objects and simple aliases for common functions. # METHODS These are methods available for the `CatalystX::ASP` object - $self->search\_includes\_dir($include) Returns the full path to the include if found in IncludesDir - $self->file\_id($file) Returns a file id that can be used a subroutine name when compiled - $self->execute($c, $code) Eval the given `$code`. Requies the Catalyst `$context` object to be passed in first. The `$code` can be a ref to CODE or a SCALAR, ie. a string of code to execute. Alternatively, `$code` can be the absolute name of a subroutine. - $self->cleanup() Cleans up objects that are transient. Get ready for the next request # BUGS/CAVEATS Obviously there are no bugs ;-) As of now, every known bug has been addressed. However, a caveat is that not everything from Apache::ASP is implemented here. Though the module touts itself to be a drop-in replacement, don't believe the author and try it out for yourself first.
