How can I do that without any GC allocation? Nothing in
std.file seems to be marked with @nogc
I'm asking since it seems very complicated to do that with
C++, maybe D is a better choice, then we would probably move
our whole project from C++ to D.
Looks like std.stdio isn't marked with @nogc all the way
either.
So for now the temporary solution would be to use std.c.stdio.
Get the file size, malloc a buffer large enough for it[1],
use std.c.stdio.read to fill it, assign it to a char[] slice
and std.utf.decode to consume the text...
Oh wait, decode isn't @nogc either. FFS, what now?
[1] I assume the file is small, otherwise there would be an
extra step
involved where after nearing the end of the buffer you move
the rest
of the data to the front, read new data after it, and continue
decoding.
How would I use decoding for that? Isn't there a way to read
the file as utf8 or event better, as unicode?
Arrays of char, wchar and dchar are supposed to be UTF strings
and of course you can just read them using a c function from a
file. You'd just need to make sure they are valid UTF before
passing them on to other parts of phobos.
What do you mean with "as unicode"?
