What are rough milestones of this project?

make apache-thrift build-able using LDC.

How does this project help the D community?

See also: #89

D is on an one man's island having trouble to cooperate with software components in other languages, due to unfixed bugs for a long time:

-- apache-thrift-d, LDC has build failure, because this bug (logged for a year now):

https://issues.dlang.org/show_bug.cgi?id=22083

-- D grpc client cannot talk to Python grpc server, because this bug (logged for 1.5 year now):

huntlabs/grpc-dlang#15

BTW, apache-thrift and grpc are the most important two rpc frameworks used in the industry.

Fixing an issue is usually not a good fit for a project. In that specific case, workarounds exist to make apache-thrift compile, don't they ?

[mw66]

If you check this comments: it's a non-trivial bug:

dlang/dmd#13257 (comment)

[Geod24]

It might be, but doesn't it have a trivial workaround ? Namely a static or renamed import ?

[mw66]

Yes, but thrift guys do not want to take my workaround PR.

It's a frontend bug anyway; and if we fix it, it help all the D projects.

I think this should go to the "Discussion" tab on DMD repo.
I have a working fix but it's not so elegant so I never committed to it, gonna check it over again.

[mw66]

@BorisCarvajal as long as it's working, it better than the current situation.

I think you should create a PR, and let people comment on it, maybe others can give better suggestions to improve it.

[RazvanN7]

Anyway, this is not a project.
