Plack::App::CGIBin - cgi-bin replacement for Plack servers SYNOPSIS
use Plack::App::CGIBin; use Plack::Builder; my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app; builder { mount "/cgi-bin" => $app; }; # Or from the command line plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app' DESCRIPTION
Plack::App::CGIBin allows you to load CGI scripts from a directory and convert them into a PSGI application. This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server. HOW IT WORKS
This application checks if a given file path is a perl script and if so, uses CGI::Compile to compile a CGI script into a sub (like ModPerl::Registry) and then run it as a persistent application using CGI::Emulate::PSGI. If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web server mode and no performance benefit is achieved. The default mechanism to determine if a given file is a Perl script is as follows: o Check if the filename ends with ".pl". If yes, it is a Perl script. o Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl script. You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument. For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you can do: my $app = Plack::App::CGIBin->new( root => "/path/to/cgi-bin", exec_cb => sub { 1 }, )->to_app; to always force the execute option for any files.
