Well, -betterC existed even then, but it was *completely*
useless. It didn't become useful until 2016 or 2017.
But around that same time, going minimal runtime got even
easier, so I never really got on the betterC train anyway. On
my tetris webassembly thing last month, I went with a minimal
druntime
http://dpldocs.info/this-week-in-d/Blog.Posted_2020_08_10.html#druntime
And it has some class support too in not a lot of code:
https://github.com/adamdruppe/webassembly/blob/master/arsd-webassembly/object.d
(and if you aren't doing classes and built-in arrays, you can
cut a bunch of that out too).
To be honest I like this approach better as it opens up for
gradually adding functionality.
Yes, indeed.
betterC is nice that it gives a library community a shared
target to rally around, but for your own custom application it
is probably better to do your own thing (though betterC might
work for you too, worth considering at least).
I tried to modify the hello.d example from your blog post. It
works without changes but when I tried to do a string
concatenation, I'm hitting linker errors related to TypeInfo:
lld: error: server/omg.o: undefined symbol:
_D12TypeInfo_Aya6__initZ
Using this in hello.d
string tmp = "hello";
tmp ~= " world !";
writeln(tmp);
I've hit this when trying to make a minimal runtime like yours
but I couldn't figure out from the LDC source how that happens.
Would you be able to help me understand how to solve this __init
symbol issue? Thanks.
