-----------------------------------
Summary: Newify transform docs missing support for local variable
declaration
Key: GROOVY-8275
URL: https://issues.apache.org/jira/browse/GROOVY-8275
Project: Groovy
Issue Type: Documentation
Components: xforms
Reporter: Eric Milles
Priority: Minor
Javadocs and online documentation for the Newify AST transform is not quite
clear in a couple instances.
1) Online docs http://groovy-lang.org/metaprogramming.html#xform-Newify
Ruby-style section could be more clear IMO if the {{([Tree,Leaf])}} were
removed since it only enables the Python-style expressions.
2) Javadoc and online docs do not mention that {{@Newify}} can be applied to a
local variable declaration, like: {{@Newify def o = Object.new()}}.
3) The scoping of the transform is pretty clear for the class, method and
field/property cases. However for the local variable case, it appears that the
transform applies throughout the containing scope of the local variable. That
is, I can use the extra constructors anywhere in the block to re-initialize the
variable. {{@Newify def o = Object.new(); ... o = Object.new() ...}}. Is this
the intended behavior? My intuition was that the initializer expression was
the only place the transform applied, like in the case of a field.
