Subject Re: Dependency injection and Plexus Compilers
Date Thu, 01 May 2008 17:12:39 GMT

Jason,

So I played around with expressions some more to see if I couldn't inject
what was needed. From what I can tell the the expression evaluator is only
applied to Mojos with Expressions in the compiler component being ignored.
Ideally this compiler would leverage the standard compiler plugin (providing
'scons' as the compilerId to have it defer to the scons plexus compiler
instance). If I was to add extra expressions I'd need to extend the compiler
plugin to aggregate them.

Am I missing something? can expressions be used in simple plexus components?
Will I need to extend the compiler plugin to get what I need? Thanks for
your help with this.

rgds,

ste
