Question

Recognising Wiki Technology and specially Twiki early december we decided to wait for the new release of Twiki. There are a few useful Plug-Ins would be required for an implementation in our company.

Reviewing the Plugin Web it seemed there are no updates to Plugins so far. We haven't found any information how the dependencies between Twiki itself and the Plugins are handled in organisational terms.

Is there a procedure aligning the Plugins to the latest Twiki Version or is it up to the contributor wether a plugin is updated or not ?

Answer

If a plugin follows the Plugin API properly and does not call into other "internal" parts of TWiki, it should not need updating between TWiki versions, because the Plugin API is designed to be backwards compatible.

That sounds confusing to me. It does mean "Tested on Twiki Version" has no meaning or doesn't matter ?

While the plugin system is designed so that plugins can be written that will be upwards-compatible with new versions of TWiki, this doesn't mean that all plugins are written in such a manner. So it is good to find out for sure whether plugins are compatible across TWiki versions.

However, the "Tested on TWiki Version" field hasn't yet had an option introduced to allow you to mark that the plugin has been tested with the 1 Feb 2003 release; that's why you won't see the new release listed.

So, to summarize:

• Regardless of the "Tested on TWiki version" field, plugins should work with any TWiki version.
• If a plugin has a TWiki version checked in the "Tested on TWiki version" field, that means that someone has actually tried it on that TWiki version and it definitely works for that version.

I hope that this has cleared things up a bit.
