I am involved on the development of a new extension, this one is very simple (like the others one) and its intended to HIGHLIGHT Syntax on code posted at the wiki. The extension will use enscript (available on all linuxes) and will put colour to the code , and them will put it under "pre" tags.

The CVS location of the code is : http://www.wickle.com/horde/cvs/cvs.php/mediawikiextensions

Requisites

There r no good programs without little requirements ;) The only one is enscript

I am using 1.6.1 but i tested sucesfully under last version 1.6.4

Download

  • Download the extension from my CVS at wickle
  • Alternate Download at SF.net : SF.net CVS

Install instructions

you must copy SyntaxHighlight.php to $mediawiki/extensions directory and add this line to LocalSettings.php: include("extensions/SyntaxHighlight.php");

Also you must set $wgSyntaxSettings->dotCommand = "/usr/bin/enscript"; to accomplish your installation of SyntaxHighlight.


Using it

To use , the only thing you must do are put the code between
<code> and </code>
tags. And inside this tags you must put one tag indicating the language used (for example
,<sh/>,
)

Samples

Perl

 
#!/usr/local/bin/perl5.8.2
#envia un correo a account_for_backups@gmail.com como usuario wickle con el backup de las
#ultimas base de datos de wickle y con el label Backup
#Usa Mail::Webmail::Gmail en #http://search.cpan.org/dist/Mail-Webmail-Gmail/lib/Mail/Webmail/Gmail.pm
#Syntax ./send_gmail.pl file_to_backup.tar.gz
 
use Mail::Webmail::Gmail;
 
my $backup_label="Backups";
my $file_to_backup=$ARGV[0];
my $mail_to_backup="account_for_backups@gmail.com";
my $now = localtime time;
print "It is now $now.\nfile to backup: $file_to_backup\n";
my ( $gmail ) = Mail::Webmail::Gmail->new(
            username => 'mygmailaccount', password => 'mypassword', );
    my $msgid = $gmail->send_message( to => 'account_for_backups@gmail.com', subject => 'Backup bases de datos '. $now, msgbody => 'Backup del dia '.$now. ' realizado', file0 => [$file_to_backup] );
    print "Msgid: $msgid\n";
    if ( $msgid ) {
        if ( $gmail->error() ) {
            print $gmail->error_msg();
        } else {
                ### Add this label to our new message ###
                $gmail->edit_labels( label => $backup_label, action => 'add', 'msgid' => $msgid );
                if ( $gmail->error() ) {
                    print $gmail->error_msg();
                } else {
                    print "Added label: $backup_label to message $msgid\n";
                }
        }
    }


bash

<sh/>

  1. !/bin/bash
  2. Getting some variables

FULLPATH=`dirname $1`; BASE=`basename $1`;

  1. Needs an argument

if [ $# -eq 0 ] ; then

 # no argument given, print usage
 echo "start control version on configuration file";
 echo "use: $0 file";

else

 # check if RCS directory exist or create it
 if [ -d $FULLPATH/RCS ] ; then
   echo "revisions directory existent ...";
 else
   mkdir $FULLPATH/RCS
 fi
 # Things to do when a RCS file exist
 if [ -e $FULLPATH/RCS/$BASE,v ] ; then
   echo "File exist. Checking for differences ..."
   # Check if there is any differences
   if ! rcsdiff $1; then
     echo "==================================="
     echo "WARNING: changes have been made to $1 and are not in the repository. Carefully look at the diff above, comment them below for committing or CTRL+C to abort."
     # Lock file
     /usr/bin/rcs -l $1
     if ! /usr/bin/ci -u $1; then
       echo "Error when commiting. Aborting"
       exit
     fi
   fi
   echo "==================================="
   echo "Getting lastest revision and locking it ..."
   /usr/bin/co -l $1
 fi
 echo "Launching editor ..."
 vim $1
 # changes made, commit them to the repository unlocked
 /usr/bin/ci -u $1
 exit
