           Summary: Special Token for Compiler and Version
           Product: D
           Version: unspecified
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: StefanLiebig web.de


Similar as the special tokens __FILE__, __LINE__,.. I would like to have a
token telling me what compiler has been used and what version the compiler had.
This could than be included in the log of the application and may help tracking
or finding problems.
Maybe __COMPILER__? Resulting in e.g. "DMD 1.014"

See std.compiler.

Theoretically, you could use the constants defined in std.compiler.
In practice, they're typically out-of-date. (case in point: they're 
currently at version 1.002 for DMD 1.014 :( )
Also, it seems the version distributed with GDC wasn't modified to 
reflect that fact, it claims to be "Digital Mars D 1.002" (like DMD 
1.002 to 1.014, apparently)...


 This could than be included in the log of the application and may help tracking
 or finding problems.
 Maybe __COMPILER__? Resulting in e.g. "DMD 1.014"


If std.compiler was properly updated, you could use something like
---
import std.compiler;
import std.stdio;

void main() {
     writefln("%s %d.%03d",
         std.compiler.name,
         std.compiler.version_major,
         std.compiler.version_minor);
}
---
to get a string representation.

Oh, I am sorry! I should have found that. I guess I was expecting something
different within std.compiler.

That is too bad. So, why not the special token?
Within mars.c there is already:
    copyright = "Copyright (c) 1999-2007 by Digital Mars";
    written = "written by Walter Bright";
    version = "v1.014";
That looks fine to me and it seems to be up-to-date.
Information that is not up-to-date but should be is confusingly.

That std.compiler is out of date is a bug.  Adding extra language features to
get around this bug wouldn't make sense - if Walter can't keep std.compiler up
to date, how would he be able to keep the workaround up to date?

Yes, std.compiler is out-of-date.
However, the information in mars.c is correct. I have scanned all my dmd
downloads   (32) and they where all correct.
I don´t know how the version gets into mars.c. Manually or automatically
(build process)? If manually than there is the tedious job of maintaining two
locations.  If automatically than the automatism has to be extended so that
both locations are in sync.

I don´t care from where I get the information, but it must be correct and I
need to trust that information.

Indeed.  But that we can't trust the information in std.compiler makes it as
bad as non-existent, if not worse.  I've just filed issue 1218, which aims at
fixing this problem rather than working around it.
