NAME

Apache::Syntax::Highlight::Perl - mod_perl 1.0/2.0 extension to highlight Perl code

SYNOPSIS

In httpd.conf (mod_perl 1):

   PerlModule Apache::Syntax::Highlight::Perl

   <FilesMatch "\.((p|P)(l|L|m|M)|t)$">
      SetHandler perl-script
      PerlHandler Apache::Syntax::Highlight::Perl
      PerlSetVar HighlightShowLineNumbers On
      PerlSetVar HighlightCSS http://path.to/highlight.css
   </FilesMatch>

In httpd.conf (mod_perl 2):

   PerlModule Apache2
   PerlModule Apache::Syntax::Highlight::Perl

   <FilesMatch "\.((p|P)(l|L|m|M)|t)$">
      SetHandler perl-script
      PerlResponseHandler Apache::Syntax::Highlight::Perl
      PerlSetVar HighlightShowLineNumbers On
      PerlSetVar HighlightCSS http://path.to/highlight.css
   </FilesMatch>

DESCRIPTION

Apache::Syntax::Highlight::Perl is a mod_perl (1.0 and 2.0) module that provides syntax highlighting for Perl code. This module is a wrapper around Syntax::Highlight::Perl.

MOD_PERL 2 COMPATIBILITY

Apache::Syntax::Highlight::Perl is fully compatible with both mod_perl generations 1.0 and 2.0.

If you have mod_perl 1.0 and 2.0 installed on the same system and the two uses the same per libraries directory, to use mod_perl 2.0 version make sure to load first Apache2 module which will perform the necessary adjustements to @INC:

   PerlModule Apache2
   PerlModule Apache::Syntax::Highlight::Perl

Of course, notice that if you use mod_perl 2.0, there is no need to pre-load the Apache::compat compatibility layer.

INSTALLATION

In order to install and use this package you will need Perl version 5.005 or better.

Prerequisites:

  • mod_perl 1 or 2 (of course)

  • Syntax::Highlight::Perl >= 1.00

Installation as usual:

   % perl Makefile.PL
   % make
   % make test
   % su
     Password: *******
   % make install

CONFIGURATION

In order to enable Perl file syntax highlighting you could modify httpd.conf or .htaccess files.

DIRECTIVES

You can control the behaviour of this module by configuring the following variables with PerlSetVar directive in the httpd.conf (or .htaccess files)

HighlightCSS string

This single directive sets the URL (or URI) of the custom CCS file.

   PerlSetVar HighlightCSS /highlight/perl.css

It can be placed in server config, <VirtualHost>, <Directory>, <Location>, <Files> and .htaccess context.

The CSS file is used to define styles for all the syntactical elements that Syntax::Highlight::Perl currently recognizes.

For each style there is a correspondant syntactical element. The elements are:

Comment_Normal

Default is {color:#006699;font-style:italic;}

Comment_POD

Default is {color:#001144;font-family:garamond,serif;font-size:11pt;font-style:italic;}

See FORMAT TYPES section of Syntax::Highlight::Perl POD for more informations about elements currently recognized.

HighlightShowLineNumbers On|Off

This single directive displays line numbers to the right of the text

   PerlSetVar HighlightShowLineNumbers On

It can be placed in server config, <VirtualHost>, <Directory>, <Location>, <Files> and .htaccess context. The default value is Off.

HighlightCache On|Off

This directive enables a very simple cache layer of already and unchanged highlighted files:

   PerlSetVar HighlightCache On

Default is Off.

HighlightCacheDir string

This directive sets cache directory

   PerlSetVar HighlightCacheDir /tmp/highlight

Default is /tmp.

RUN TIME CONFIGURATION

In addition, you can control the module behaviour at run time by adding some values via the query string. In particular:

download

Forces the module to exit with DECLINED status, for example by allowing users to download the file (according to Apache configuration):

   http://myhost.com/myproject/sample.pl?download
showlinenumbers

Forces showing of code line numbers. For example:

   http://myhost.com/myproject/sample.pl?showlinenumbers
