But dlang has a long problem of change constantly without backward compatibility and a lot of projects just die because of it, for example the mentioned https://github.com/facebookarchive/warp :

====

> die because of it

That isn't why Warp was discontinued. (My last change to Warp was 7 years ago.) Even with my C code, it's unsurprising to have to update a few things after 7 years.

My version of the repository is:

https://github.com/DigitalMars/dmpp

and compiles with DMD 2.067. I'll see about updating it later today. Stay tuned!

Those are 8 errors, all from 1 language change, which can be fixed by inserting 8 characters.

After following the compiler suggestions (several times more):

====

make

util.d(20): cannot pass argument `& makeGlobal` of type `File function() nothrow @nogc @property ref @system` to parameter `File* f`

Less than 30 line changes to get it to compile with latest DMD. https://github.com/DigitalMars/dmpp/commit/a9b879983130cf3a3...

Small price to pay for an elegant language.

Put () after the stderr and it'll compile.
