Reencoding MediaWiki pages
Revision as of 21:17, 17 November 2009 by imported>Cov
The following script will convert HTML from a MediaWiki page to Wikitext. The script was written to facilitate the 2009 VTLUUG servers migration.

Running
The following command will create .wikitext files of the HTML files for your cut and paste convenience.
for f in *.html ; do $( sed -rn -e '/<!-- start content -->/,/<!--/p' $f | sed -r -f script > $f.wikitext ) ; done
Copying
Once the .wikitext files are generated, you can simply open them up, edit them by hand if necessary, and copy and paste them into MediaWiki. Noting that this is an import in the summary box is recommended.
gedit *.wikitext
Effectiveness
The script was effective enough for our purposes when written, but it has some shortcomings. Images and local article links are handled poorly and it does not attempt to produce the brace-bar-dash table markup.
