gprof will do this on Linux/BSD if gdc supports the -pg flag (I
don't know whether it would, but assume so) and your
application is working.
From code, you'd need to call a trace function on function
entry. Mine lets you also specify a message (parameter values,
etc.):
---
void trace(T...)(T args, string func = __FUNCTION__) {
import std.stdio : writeln;
if (args.length > 0) {
debug writeln("*trace: ", func, "- ", args);
} else {
debug writeln("*trace: ", func);
}
}
void main(int a, string b) {
trace();
trace(a, ", ", b);
}
---
You can also generate a call graph using callgrind.
That however will slow down your program.
There are some python script that converts the output of
callgrind to a dot file that can be converted to svg.

Re: Map of functions
Do you really have a nested function print() inside a nested
function calculate() inside main()? That is,
Hi
this is only an example of names of funcions but the structure is
this:
void main()
{
// maybe some calls to calculate()
}
void calculate()
{
// maybe some calls to print()
}
void print()
{
}
I need the flow of calls.
Thank you
Giovanni

Hi
Is there an utility to print
the functions in a source file, for example:

Or are you talking about the sequence in which function are
*called*, and from where? Please clarify.

Hi Is there an utility to print the functions in a source file, for example: - main() --- calculate() - print() --- simulate() - print() . Thank you very much Giovanni Di Maria
