Care to elaborate on why you are creating all of these new templates and what you plan on using them for?

OK, thank you for clarifying this :)

As you seem to be a maven maven :-), perhaps you can shed some light on this: I'm using Fedora 16, and on a clean Git clone of mwdumper, mvn package successfully builds build/mwdumper-1.16.jar. But when I want to execute it:

[tim@passepartout ~/src/mwdumper.2]$ java -jar build/mwdumper-1.16.jar

Any idea why this doesn't work?

I am seeing this problem as well when building mwdumper. This class is not included with the source code, so it's not compiled with the maven code from the git repository. Unfortunately I didn't find any documentation to solve this problem and mwdumper code has no documentation as well. Any help you find handles versions which are 5 or more years old :(

Crazy enough, but on:

https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/tools/mwdumper.git;a=summary

go back in time to this entry:

2009-11-22 Robert Stojnić Parse the title into Title format for liquid threads commit | commitdiff | tree | snapshot

and click on snapshot. Build from that download. You might find it works for you. For me, it was the first that didn't give me the headache you describe... all newer ones did.

Good luck!

Thanks, it works!

I removed all references with bz2 from the sources:

- commented out the BZip2 lines (with the corresponding "if else") and classes in Tools.java and Dumper.java

After that the project started successfully with the latest git.

Ofcourse, no bz2 for you.

Hi. Since you're into search stuff, mind taking a look at http://www.mediawiki.org/w/index.php?title=Project:Support_desk&offset=20120725221759#How_do_I_format_search_results_.2F_add_section_links_to_search_results_.28the_same_way_Wikipedia_and_other_WikiMedia_sites_do.29.3F_17658 ?

Hi Oren, Sumana talked to me and said that you could use wikimedia labs for the project you work on (some search project). If you wanted to create a virtual instance for your development and testing, please step in #wikimedia-labs and I will be happy to help you! :)

Hi will look for you at #wikimedia-labs.

I could use some assitence in getting my subversion to work using svn+ssh.

Well, every DB backend seriously supported has its own full-text search, though they're inferior if compared with Lucene.

Hi Max, my point is more along the lines that Lucene integration requires a couple of extensions which are not installed by the installer. Rather than being part of the core and being an option for installation.
