This new warning adds a lot of warnings in the Cappuccino frameworks. I have turned off
the warning in the Jakefiles when compiling most of the Cappuccino frameworks. But it is
on as default for any user projects.
So there is also a new feature to turn off/on warnings as a compiler flag.
These flags are (all flags are on as default):
-Wunused-but-set-variable Warning when a local variable is never read.
-Wshadow-ivar Warning when a local variable is shadowing an instance variable for the class.
-Wcreate-global-inside-function-or-method Warning when creating a global variable inside a function or method.
-Wunknown-class-or-global Warning when a class or global variable is not known.
-Wunknown-ivar-type Warning when the type for an instance variable is not known.
To turn off a flag add a 'no-' prefix. Example: -Wno-unused-but-set-variable
For an example how to use it in a Jakefile please look at the Jakefiles in this commit.
The life will be easier to have the same in both environments.
Warnings and errors now don’t use read only properties for line and column information. So the test cases in Toolstest.j now work in modern JS engines.
It is also easier to set options for the compiler.
