Or __FILE__, __LINE__, etc. etc.?

I really need __DATE__

Hear! Hear!. I also would love to have these compiler generated values. They can give meaningful information to people who are trying to find errors happening at a customer's site. It helps narrow down what version they are running and where a run-time message is really coming from.

Are these actually that useful in a language that doesn't have a macro preprocessor?

> I really need __DATE__

Date of what?  The file's timestamp?  When it is compiled?

What data type/format would it be?  A d_time?  (Most sensible for as long as d_time remains the nearest we have to a standard date type.)  A string as formatted using std.date.toDateString or std.date.toString? Something else?

And do we really want to use reserved identifiers for this?

I'd go further and introduce __FUNC__ which gives us the function name and also __MODULE__, which gives us, right, the module name. This would be really neat, I need some of them, too!

But aren't __FILE__, __LINE__, __DATE__, __TIME__ all
part of that ancient old preprocessor which is so evil ? ;-)
I also find the GCC extension __FUNCTION__ to be useful.

Wouldn't it be possible to add these as constants to
the lexer, without messing up the language to bad ?
Or it could be like an escape sequence or something...


But easiest would just be if they were "special" literals.

char[] file = __FILE__;
int line = __LINE__;

char[] date = __DATE__; // "??? ?? ????"
char[] time = __TIME__; // "??:??:??"

char[] module = __MODULE__;
char[] function = __FUNCTION__;

Doesn't sound impossible to hack into the DMD front-end...

When it is compiled...

Something else:
__DATE__ = "Mar  7 2005";
__TIME__ = "15:44:00";

> And do we really want to use reserved identifiers for this?

Well, we *could* use date and time and file and line...

It would "silently break" a couple of dozen people's
code, but they should be used to that since length ? ;-)

It is very usefull!
And why "preprocessor"? This is "compiler-predefined constants".

Build can do that, it's exactly the same thing as plugins. I explained how we could do it in my last post: http://www.dsource.org/forums/viewtopic.php?t=624

Nice suggestion.

I have added it to my wish list under compiler values. http://all-technology.com/eigenpolls/dwishlist/
