If I start pulling from the opensvn server, etc., is there some way to  
confirm or find out which version of an engine (engines plugin,  
login\_engine, user\_engine, etc.) I have, once I’ve installed it in the  
vendor/plugins/ directory (i.e., without a version numbered  
dir)?

For instance, I would like to first find out which engine plugin I have  
already (1.05?)–and I’ve installed it with script/plugin install (not  
SVN, obviously I could figure it out if I did an ‘svn co’–but not an  
‘svn export’ however!), then perhaps install one from a particular rev,  
like 242… and so on.

Tx,  
Brad

Good idea.

Answering my own question (with offline help from James–thanks!) →

Look in /vendor/plugins//CHANGELOG

This will give you the _released_ version number. If you have ‘checked  
out’ a work-in-progress revision from opensvn.csie, then you should be  
able to determine the revision using SVN of course; if you exported  
however, then (currently) you’re out of luck.

There is now a ticket to add a “revision number revealing” rake task to  
the engines codebase (tkt #71, found here:  
[https://opensvn.csie.org/traccgi/rails\_engines/trac.cgi/ticket/71](https://opensvn.csie.org/traccgi/rails_engines/trac.cgi/ticket/71) ).

There is now support for giving version information with engines -  
please check out the latest Engines plugin & documentation for more  
details.
