MediaWiki to Dokuwiki Converter

I hosted this site on wiki.splitbrain.org, the official site, because it fits in there and the bandwidth here is not the best. I’ll try to keep these pages in sync. Post there!

A online converter is now hosted at http://johbuc6.coconia.net/mediawiki2dokuwiki.php.

Hey, I was playing with awk & perl a little bit. I created a MediaWiki to Dokuwiki Converter.

• bash
• perl

It is able to transform

• Links
• Bold/italic text
• Lists
• Talkings
• Code

• One Page at once

It is not able to transform

• tables

File mediawiki2dokuwiki.sh:

1. Make sure you are under Linux/Unix
2. Save the code above in a file named mediawiki2dokuwiki.sh.
3. Save the Mediawiki Site you want to transform to a file called mediawiki in the same directory.
4. In the shell go to the directoy (using cd) and execute:

   chmod +x mediawiki2dokuwiki.sh #we want to be able to execute it
   ./mediawiki2dokuwiki.sh

5. Now you got some files called mediawiki+a number. These are debugging steps (ignore).
6. In the file ‘dokuwiki’ you’ll find your DokuWiki-Syntax.

Remember, all the fame goes to me, cause I started this ! — Johannes Buchner 2006-01-26 19:27

Would be great if someone wants to improve this! What is needed:

• See Limitations & Missing features
• A webbased service: now available: http://johbuc6.coconia.net/mediawiki2dokuwiki.php.

• Yeah, i could remove leading whitespaces at all, but this might ruin the design. Johannes Buchner 2006-01-27 11:41
• I just began to implement tables with:

    perl -pe "s/^[ ]*\{\|[^\|]*$//g" |
    perl -pe "s/^[ ]*\|\}[ ]*$//g" |
    perl -pe "s/^[ ]*\|([^\|]+)\|[ ]*$/|${1}|/g" 
    # ...
  

  But tables in Wikimedia are crap. I suggest to use a html2wiki implementation for this need (’cause the needs will be very special) like http://diberri.dyndns.org/html2wiki.html Johannes Buchner 2006-01-27 12:00
