Hi all,
on http://docs.codehaus.org/display/GroovyJSR/GEP+3+-+Command+Expression+based+DSL you find a new GEP, to have better DSLs in Groovy. It is a very first draft, so don't expect too much. Of course suggestions are welcome! bye blackdrag -- Jochen "blackdrag" Theodorou The Groovy Project Tech Lead (http://groovy.codehaus.org) http://blackdragsview.blogspot.com/ --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |

"In certain cases, you can remove commas from method invocation expression lists. The method invocation will become a series of chained invocations of expressions pairs where the odd numbered expression is assumed to be a method and the even numbered parameters are objects. This works if you have an odd number of expressions unless the last expressions is a closure. Also, this works for an even number of expressions only if the last expressions is a closure. " There are a few details left out, but is that the gist of it? I feel like I see the pattern from the example but don't quite know how to explain it. -- Hamlet D'Arcy hamletdrc@...

So whatever happened to GEP 3 (Command Expression based DSL)?
Are we re-thinking it or moving forward with it? -- Hamlet D'Arcy hamletdrc@...

Only I had not time yet for this bye blackdrag -- Jochen "blackdrag" Theodorou The Groovy Project Tech Lead (http://groovy.codehaus.org) http://blackdragsview.blogspot.com/ --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |
