I haven't found a detailed description of simple aliases. TPDL shows aliases of this form:
alias TYPE NAME; with some complex examples of D types aliased to a simpler name. The D lang web site language reference says nothing about aliases (except as it's described in the grammar), and the D lang wiki gives only one simple example on page "http://wiki.dlang.org/Converting_C_.h_Files_to_D_Modules#Types";. I need help because I'm zeroing in on properly converting C headers to D bindings and have found some interesting (and confusing to me) results. The following, uncommented-out aliases all compile with "dmd -c file.d": // note the two forms: "alias TYPE NAME;" and "alias NAME = TYPE;" alias int val0; // C: typedef int val0; // okay alias val1 = int; // C: typedef int val1; // okay alias val2 = int[2]; // C: typedef int val2[2]; // a 2-element // array of ints (int[2])? alias int[2] val3; // C: typedef int val3[2]; // a 2-element array of ints (int2)? //alias val4[2] = int[2]; // D error (okay, understandable) // these compile but have no C equivalent that I know of, but what do // the aliases represent? alias int[2] val5[2]; // D: a 2-dimensional array of ints? (int[2][2]) ? alias int[4] val6[2]; // D: a 2-dimensional array of ints? (int[4][2]) ? alias int val7[2]; // D: a 1-dimensional array of ints? (int[2]) ? I have marked with question marks the ones I'm not sure how to interpret, although I have given my somewhat educated guess. Confirmation or correction would be very helpful. If we get a consensus, I'll update the wiki. Thanks, Best regards, -Tom
