Hello, I'm new to D, my origin is C++.

I want to search for a value in an ini file. I search for the right section,
e.g. "[D]", and then I want to find the variable, like "variable=", and then
change it's value.

This is how I try to do it:

char[] bfr;
bfr = cast(char[]) read (ini_path);
int i = find (bfr,"[D]");
i = find (bfr+i, "Compilator File=");

Since bfr is "char[]" and i is "int" it's erroneous. However none of my trials
to bypass this type-problem were successful.

How do I do it ?

Thanx in advance,
Tal

"Pointer magic" does not apply to D arrays, as they are not just flat pointers,
but a 
structure of a pointer and length.  Assuming your INI requires entities be on a
line 
alone, you could break the string into lines first.  Or, you could use a slice.
 Example:






That said, it might actually be easier to go with lines, or just parse out the
entire 
file, manipulate, and dump back to disc.

Looks like it will also match with:
    [Foo]
    bar=3Dthis [D] is not a section.

but to get a substring:
    bfr[i .. bfr.length]
