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 string alias was added in DMD 1.016:
http://www.digitalmars.com/d/1.0/changelog.html#new1_016

GDC 0.21 was based on DMD 1.000, but I have no idea what GDC 0.23 is 
based on as I cannot see that info on the GDC page.

I suspect it's still based on DMD 1.000 and therefore has no aliases.

However, the aliases are defined in phobos and I suspect if you grab the 
latest phobos source and build it you will solve your problem.

Ahh, thanks.

I was looking here:
http://dgcc.sourceforge.net/#doc

I saw the link to gdcmac and gdcwin but I didn't follow them.

GDC 0.23 is based on DMD 1.007, so that explains my problem.

Thank you very much,

The example is using D 2.0, while GDC supports D 1.0 at the moment.
(the language was split into two different versions a while ago...)

int main(char[][] args)

Technically I guess it's D 1.016 or D 2.0 code.  Am I correct about 
rebuilding phobos (in my reply to the OP) or will that fail utterly?

You are right, it'll probably be fixed in GDC 0.24 then. (DMD 1.018)

The aliases can probably be added to the object.d manually meanwhile
alias char[] string;
alias wchar[] wstring;
alias dchar[] dstring;

This is example of D 2, code. Who the hell published this on Wikipedia?

use:
int main(char[][] args) {
...
}

or put "alias char[] string;" before main

string was added in DMD 1.016, which corresponds to GDC SVN revision 134. GDC 
0.23 is only up to DMD 1.007, so get the latest GDC. You can find instructions 
in http://dsource.org/projects/tango/wiki/UnixInstallGdc, down to the "GDC 
Installation from source" section.

the string alias was added in dmd 1.016 (which btw was a horrible idea
imho), and with gdc 0.23 being 1.007 it's not availble, seems like someone
was a bit enthusiastic updating the wikipedia pages.
