NAME¶
CGI::Compile - Compile .cgi scripts to a code reference like ModPerl::Registry
SYNOPSIS¶
use CGI::Compile;
my $sub = CGI::Compile->compile("/path/to/script.cgi");
DESCRIPTION¶
CGI::Compile is an utility to compile CGI scripts into a code reference that can
run many times on its own namespace, as long as the script is ready to run on
a persistent environment.
NOTE: for best results, load CGI::Compile before any modules used by your
CGIs.
RUN ON PSGI¶
Combined with CGI::Emulate::PSGI, your CGI script can be turned into a
persistent PSGI application like:
use CGI::Emulate::PSGI;
use CGI::Compile;
my $cgi_script = "/path/to/foo.cgi";
my $sub = CGI::Compile->compile($cgi_script);
my $app = CGI::Emulate::PSGI->handler($sub);
# $app is a PSGI application
CAVEATS¶
If your CGI script has a subroutine that references the lexical scope variable
outside the subroutine, you'll see warnings such as:
Variable "$q" is not available at ...
Variable "$counter" will not stay shared at ...
This is due to the way this module compiles the whole script into a big
"sub". To solve this, you have to update your code to pass around
the lexical variables, or replace "my" with "our". See
