digitalmars.D - DDMD is now in the master branch

reply "Daniel Murphy" <yebbliesnospam gmail.com> writes:
Several hours ago, Walter merged my DDMD branch into master.  This means 
that an additional 'ddmd' target is available in the makefiles, and the 
autotester will check that it builds.

The make target converts the C++ frontend source to D, and then compiles 
with the host dmd.  The converter is included in the DMD repo for now.

If you are a DMD developer, pull requests may need to be updated to modify 
the converter's configuration file, or to replace problematic code that 
cannot be converted.  Details can be found here: 
http://wiki.dlang.org/Updating_Pull_Requests_for_DDMD

For everyone else, please test the generated ddmd binary with your projects 
and report any correctness or performance problems you encounter.  I'm also 
interested in feedback on the quality of the generated D source.

When we are satisfied with the quality of the D version, we will switch over 
all development to it and delete the C++ source.  If we're lucky this will 
happen before the 2.068 release.

Thanks to everybody who has helped with DDMD over the last two years.

Good news,

little question as ddmd generate a code does this means that ddmd
backend and frontend is full open source under boost license?

IIRC ddmd is only the frontend.

The backend is still in C++ and the license is unchanged.  And most likely 
will never change.

We are working to mitigate this by restructuring the frontend so that it is 
easier to maintain GDC and LDC, in the hope that they will be able to follow 
the dmd frontend version much more closely.

Also, translating code to another language creates a derived work and does not 
obviate the copyright or license.

That would be great, though being able to compile ddmd with ldc 
and/or gdc is necessary IMO to make it releasable. What's missing 
to make that work?

Not sure, but they will most likely need to be updated to 2.067.  The main 
issues are likely to be C++ ABI related.

I'm so incredibly proud that you've achieved this. The fact that we'll
be able to hack on the D compiler in D -- is just beyond words.. I'm
speechless.

Fantastic work.

Great work!  Looking forward to all the benefits that will drop 
out of most of the frontend being written in D itself.  I know I 
find D easier to read than C++, so it'll help me.
