21 Plack::App::CGIBin allows you to load CGI scripts from a directory and
22 convert them into a PSGI application.
23
24 This would give you the extreme easiness when you have bunch of old CGI
25 scripts that is loaded using cgi-bin of Apache web server.
26
28 This application checks if a given file path is a perl script and if
29 so, uses CGI::Compile to compile a CGI script into a sub (like
30 ModPerl::Registry) and then run it as a persistent application using
31 CGI::Emulate::PSGI.
32
33 If the given file is not a perl script, it executes the script just
34 like a normal CGI script with fork & exec. This is like a normal web
35 server mode and no performance benefit is achieved.
36
37 The default mechanism to determine if a given file is a Perl script is
38 as follows:
39
40 • Check if the filename ends with ".pl". If yes, it is a Perl script.
41
42 • Open the file and see if the shebang (first line of the file)
43 contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a
44 Perl script.
45
46 You can customize this behavior by passing "exec_cb" callback, which
47 takes a file path to its first argument.
48
49 For example, if your perl-based CGI script uses lots of global
50 variables and such and are not ready to run on a persistent
51 environment, you can do:
52
53 my $app = Plack::App::CGIBin->new(
54 root => "/path/to/cgi-bin",
55 exec_cb => sub { 1 },
56 )->to_app;
57
58 to always force the execute option for any files.

66 See also Plack::App::WrapCGI if you compile one CGI script into a PSGI
67 application without serving CGI scripts from a directory, to remove
68 overhead of filesystem lookups, etc.
