digitalmars.D.learn - string not aliased

Hi all,

I'm a complete newbie to D, and tried the examples on the Wikipedia
page. the example 2 shows a main function like this:

int main(string[] args)   // string is a type alias for const(char)[]

But, I get this error on compile:
hello.d:3: Error: identifier 'string' is not defined
hello.d:3: Error: string is used as a type
hello.d:3: function hello.main parameters must be main() or
main(char[][] args)

Is the guy writing the example wrong? Or is it my environment? (gdc
0.23, on Mac OSX 10.4)

Thanks,

The current gdc supports d version 1.x.  The example you're doing, I believe,
is for an alpha version of d (version 2.x).  const(char) and various
const/final/invariant stuff was added in 2.x (and is the reason for the version

OK, thanks. Does anyone knows when gdc will have D2.0?

Cheers,

You can get "string" alias before D 2.0, though ? It came
in DMD 1.016 and the GDC svn is currently up to DMD 1.020...

David Friedman hasn't published any E.T.A. on GDC 2.0 yet.
Could be since we haven't reached GDC 1.0 yet, but anyway. :)

Thanks, got svn gdc and it works. Just one thing: gdc --version still
says it is synced to DMC 1.007, which is a bit confusing...

Indeed (that was true for GDC 0.23) It probably just hasn't been updated
yet, but should be before release (was wrong in a previous GDC version*)

You can enter a bug for it in Bugzilla perhaps, unless it's updated soon
Usually one can go off the ChangeLog, where it says "Merge DMD X.YYY"...
