Earlier the compiler generated the 'if' without the last ';' when a empty statement is used, with sometimes devastating result. The same if an empty statement was after the 'else'.
I have also added a test case for some different empty statement senarios.
The program below crashed on the last line with a 'null is not an object' error message. Also added a test case.
@implementation MyObject {
- (int):(int)a {
return a;
}
@end
var a = [[MyObject alloc] init];
var b = [a:3];
'@ref' is generated to ' function(__input…' with the starting space if, for example, the code is 'return(@ref(a))'. This will create a space between 'return' and 'function(__input…'. When the compiler is generate the code this is not necessary.
The compiler can now run in IE8. Also found the use of the function .indexOf on Arrays in CPView.j.
It is not supported in IE8.
Added a new file (OldBrowserCompatibility.js) in the Objective-J framework that will add functions if they are not supported in the javascript runtime.
This change makes it possible to @deref any expression, such as a conditional expression, as long as the expression doesn't have side effects.
The reason not to allow dereferencing of expressions with side effects is that we might need to evaluate the expression twice in certain uses of deref, which is not obvious when you look at the deref operator in plain code.
Array literals look like `@[a, b, c]`.
This syntax is supported for completeness and source compatibility, but are not terribly useful since standard JavaScript arrays are toll-free bridged to CPArray.
Array literals could be handy if you're replacing CPArray with your own implementation.
