The docs say:

Strings can be copied, compared, concatenated, and appended: char[] str;

char[] str1 = "abc";

str1 = str2;

if (str1 < str3) ...

func(str3 + str4);

str4 += str1;

with the obvious semantics.

It errors out with "Array operations not implemented". I see that concatenantion is supported by ~. Am I missing something here?

Cheers,

as you say, suported with ~.. so use ~instead of +

func(string3 ~ string4);

string3 ~= string4;

and similar..

not sure about the <, i have to read that up again, haven't used it yet.. In article <blv327$15gn$1@digitaldaemon.com>, Sarat Venugopal says...

Two comments:
1) do be aware that D is still a work in progress.  I'm never certain before I try just which language features have actually been implemented.
2) shouldn't that be str4 ~= str1 rather than str4 += str1 ?
2a) if you're missing a feature, you might be able to implement it yourself in a subclass via redefining the operation.  (I admit I haven't tried this with the "array of chars" type.  But for some other's it's worked well.... I say without having gotten the application to the point where I can do unit testing.)

Comparisons (<, >, and ==) work for me.  Use the ~ for appending and concatenation.  I've attached an example that works on my system.  If my example doesn't help, it might be useful for you to post a complete example (whether it compiles or not).

I'm running WindowsXP.  I don't know if my example works on the Linux version (if it doesn't that would probably indicate a compiler bug).

Hope this helps.

The documentation is wrong; '~' is the concatenate operator for strings, not '+'. Similarly, use  '~=' for append, not '+='. I've corrected the documentation.
