What is the official way of programmatically determining the version
number of the currently executing dmd?

Thanks.

AFAIK, there isn't a way. You can only determine D2 vs D1. It would be a good feature to add to druntime though. Since druntime is inextricably linked with dmd, you could define an enum with the minor version. I remember Tango does this. -Steve

There is the special Token __VERSION__ which gives an integer. http://www.digitalmars.com/d/2.0/lex.html greets Matthias

__VERSION__. http://www.digitalmars.com/d/2.0/phobos/std_compiler.html

Sadly (perhaps), when I said programmatically, I actually meant from Python. So gcc has the -v option giving output that can be "parsed" to=

 find the version number.  javac has the -version option, as does
 groovyc. OCaml has a -version option.  gdc has a -v option. I could go
 on.  dmd seemingly has no option for delivering a version number.  Whic=

 is sad.
=20

ersion is to use the =E2=80=9C-dumpversion=E2=80=9D option, whose output contains o= nly the version. Jerome --=20 mailto:jeberger free.fr http://jeberger.free.fr Jabber: jeberger jabber.fr

 So you can parse the first line of this output.

OK, that is the same as "dmd --help", I can make it work. Thanks.

Just for fun, try: dmd -man !!

Also, there's std.compiler, which "decodes" the information in __VERSION__. http://www.digitalmars.com/d/2.0/phobos/std_compiler.html -Lars

That presupposes you are connected to the Internet. Much of the time I am not. I appreciate this is an almost heretical position to be in but mobile Internet hasn't actually arrived despite being sold. Interestingly, or not, Go allows for imports to refer to non-local Bazaar, Mercurial and Git repositories without local caching which means you can't compile code unless you are connected to the Internet.

I've had an idea lately on that note. I'd think it would be cool if
rdmd (not standard dmd) had support for this style of import magic:

//  grab url:http://someserver.com/somelib/v1.0/src/somelib/somemodule.d
size:4321 sha1:2fd4e1c67a2d28fced849ee1bb76e7391b93eb12
import somelib.somemodule;

The hash & size of the file are there to make it very hard for someone
to take over someserver.com and put malicious code there which people
would download & run.

rdmd could also have options for turning this feature off/on or into
interactive mode where the user has to accept each download. Lets role
some local cashing in there while we're at it also. :) Refraining from
having a hash & size in there could be useful for unstable code but
those imports should not be used without conscious input from the
user. One could be allowed to view the code before typing "yes" and
having the code put into the cache.
