Subject Thoughts on flowscripts....
Date Fri, 14 Nov 2003 16:52:03 GMT
Been thinking about the flowscript issue, and wanted to float some other 
thoughts regarding consistency.

In my mind, some level of consistency is a "good thing(tm)", and leads to two 
precepts:

1) Consistent syntax should perform consistently similar functions.
2) Consistent names should denote consistent things.

So that begs the question:

Why does <map:call resource="xxx"/> behave like a method invocation and 
returns to the sitemap and continues execution a the point that was left off 
(assuming the last item in the resource wasn't a serializer).

But <map:call function="xxx"/> is expected to never return by always doing a 
showPage() or showPageAndWait()?

This is a Cocoon inconsistency in how <map:call> behaves which breaks the 
first precept.

Maybe it should be renamed <map:flowscript fuction="xxx"> in the latter 
circumstance or something other than <map:call>?

In most programing languages in common usage a "call" implies a return, so 
there is also an inconsistency here with accepted terminology with respect to 
the flowscript syntax. This breaks the 2nd precept wrt to common definitions.

Just some thoughts...
