[Cpptool-develop] Adding variable declaration in if/while statement...

[Baptiste L. <gai...@fr...>]

    Hi,

    I'm in the process of adding variable declaration to if/while
statements:

    if ( int c = nextChar() )
    ...

    This is actually done. When updating the test for the ScopeGenerator, I
actually found a bug: the condition scope is not parent of the then and else
statement scopes. I'm in the process of changing this. It will likely
involve a partial rewrite of the ScopeGenerator class, so avoid change to
this class.

    The current solution I've found is to drive more of the visitation from
the 'scope generation description'. Basically, the description should
indicate that for a while statement node,
    - the condition scope should be created
    - condition expression should generate scopes (variable declarations)
and make the condition scope the parent
    - scopes should be generated for the then and else statements and the
scope generated by the condition expression should be their parent.
    - then and else statement node should be visited for further scope
generation.

    Not yet well defined, but that's the general idea.

    Baptiste.
