a quick peek in the source shows that debug <=> debug(1)

is this sane behavior?

Yes, that's normal behaviour. And:

$ dmd2 -debug=ellery test

will print "hi!" if the code is:

debug(ellery) pragma(msg,"hi!");
void main() {}

I won't close this as invalid because the specification doesn't say exactly
this. It says:

---
The debug condition is satisfied when the -debug switch is thrown on the
compiler.

The debug ( Integer ) condition is satisfied when the debug level is >=
Integer.

The debug ( Identifier ) condition is satisfied when the debug identifier
matches Identifier. 
---

It should say:

The debug condition is satisfied when the -debug switch is thrown on the
compiler or when a debug level >= 1 is indicated.

(or something like that)

(In reply to comment #2)
 Yes, that's normal behaviour.
According to whom? The C preprocessor? When I read the spec, I came away with the impression that debug should work like so: debug { stuff } should get compiled if the compiler is given -debug or -debug={something}. Basically, I see it as a boolean. Are we in a debug compile? debug(number) { stuff } should get compiled if the compiler is given -debug=n, where n >= number (and there's nothing that says debug(0) { stuff } will always get compiled) wait, I'm seeing a pattern here 1 -> true, 0 -> false. That sorta makes sense. debug(id) { stuff } should get compiled if the compiler is given -debug=id Yeah, spec needs to be more precise. I would like to see -debug=id => debug_level=1, though. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
