cdecl test cases

T

Tor Rustad

Did a fun project some years ago.. a cdecl, but never really tested it.

Here are some test cases I just tried:

cdecl> char **argv;
cdecl> argv is pointer to pointer to char
Looks ok

cdecl> int (*daytab)[13];
cdecl> daytab is pointer to array [13] of int
Looks ok

cdecl> int *daytab[13];
cdecl> daytab is array [13] of pointer to int
Looks ok

cdecl> void *comp();
cdecl> comp is function returning pointer to void
Looks ok

cdecl> char (*(*x())[])();
cdecl> x is function returning pointer to array of pointer to function
returning char
Looks ok

cdecl> char (*(*x[3])())[5];
cdecl> x is array [3] of pointer to function returning pointer to array
[5] of char
Looks ok

cdecl> char* const *(*next)();
cdecl> next is pointer to function returning pointer to (read-only)
pointer to char
Parse error: ";" at line 255. Hint: Not a valid type.
Looks ok, except for the parse error.

cdecl> char **(c[10])(int **p);
cdecl> c is array [10] of function returning pointer to pointer to char
Looks ok

cdecl> void (*signal(int sig, void (*func)(int)))(int);
cdecl> signal is function returning pointer to void
cdecl> void (*signal(int, void (*)(int)))(int);
cdecl> signal is function returning pointer to void
Not ok

Did I miss something here, or do people agree with the above?
(I don't have another cdecl to cross-check with)

Does someone have ideas for more test-cases?

My cdecl shows:

cdecl> explain void (*signal(int sig, void (*func)(int)))(int);
syntax error

I don't think the version of cdecl that I have handles multiple
identifiers in a single declaration (signal and func in this case).

cdecl> explain void (*signal(int, void (*)(int)))(int);
declare signal as function (int, pointer to function (int) returning
void) returning pointer to function (int) returning void

Look good.

The version I have is very capable and featureful and supports readline
if you have it. It was written for Linux but should be easy to port to
similiar systems. You can download the source code package, which
comes with a mini test quite, at:
http://www.ibiblio.org/pub/Linux/devel/lang/c/cdecl-2.5.tar.gz.

Thanks! Does

explain char **(c[10])(int **);

also give a parse error?

Right, IMHO that would be useful for cdecl to handle.
cdecl> explain void (*signal(int, void (*)(int)))(int);
declare signal as function (int, pointer to function (int) returning
void) returning pointer to function (int) returning void

Look good.

Yup, agreed.

Windows box here, which lack readline, yacc and flex!!

Took a look at the package, and it was far more advanced than my
little C utility (850 lines of yacc code vs 200 lines of C parser code).
For now, I only want to get 'explain' working with C89 (and C99).

I see one main thing for me to add then, and that is to parse/display
the argument list of functions... <g>

Minor detail - that has been zipped with something outlandish, and
neither unzip (info-zip 5.51) nor pkunzip (katz 2.50) can extract
it.

My apologies. I used PKZIP originally; rezipped with gnu zip 2.3.

Of course you snipped the URL, so now I don't know where to go for

And now I found the old URL, redownloaded it, and you omitted the

My, you are one hard to satisfy customer...
