how to... make a D library and distribute?
I want to send out a D library (.lib) I made to a friend.

With Java and Java's .jar files, he can link them right into his project and
everything works.

With D Programming Language, do I have to make a "header" file to distribute
with my D library?

If so, I thought D was supposed to get away from needing header files?

And if so, is there a way to automatically generate the tandem D "header" file
for the distributed library?

Thanks,

Yep.

There are several threads about this.  Some people are working on ways to 
implicity import functions, classes etc. from .lib files.

I think Derek Parnell is working on putting this functionality into his 
"build" utility.  I've also been meaning to make a tool to do just this (as 
I have run into the same problem), but I haven't had much time.

There has been a few topics reviewing the need for a headerless D in the 
digitalmars.d newsgroup.  You might like to have a look there.

Currently, you do need to provide an D "header" (aka stripped import 
module of your project source) with your D library (.lib).  I believe 
digc (see the undig project at dsource.org) does this sort of thing 
already.  Burton created digc as part of his dig project a few years 
ago.  I don't know if it still works now.

The reason you keep hearing about D's ability to operate headerlessly is 
because that feature used to be frequently advertised as a an advantage 
of the language.  The only problem is that such a feature is still 
absent from all current d tools, though technically feasible and 
certainly much anticipated by everyone here.

As of now, the project that shows the most promise in this area is 
Eric's DDL project over at dsource.org.  It looks like he's making 
tremendous headway.  Keep on eye on that one if your interested in 
seeing D gain a feature that may single handedly propel D into 
super-stardom status ;-).

Hi John & Jarrett,

Thanks for the info!

I was concerned that I was missing something fundamental.

Great to hear there are several different strategies being tested to 
resolve the issue!

Sincerely,
