gostd

This is a toy project where I attempt to rewrite and transpile Go packages with C++ (without using the C++ standard library):

#include <gostd/fmt.hpp>
#include <gostd/os.hpp>

using namespace gostd;

int main() {
    auto [n, err] = fmt::Println("hello, world!");
    if (err) {
        fmt::Fprintln(os::Stderr, "error!", err);
        return 1;
    }
    fmt::Println("wrote", n, "bytes");
    return 0;
}

I don't know how useful this is, but I find it fun.

"Packages"

Package	Status	Notes
archive/ar	Original	Like archive/tar, but for ar archives. Used by gostd test.
bytes	Partial	Hand-written as needed.
cpp	Original	Includes C++-style implementations (mostly from stdlib) as needed.
debug/macho	Partial	Hand-written to the extent that gostd test requires on macOS.
encoding/binary	Partial	Hand-written as needed.
errors	Complete	Hand-written.
flag	Partial	Hand-written as needed.
fmt	Partial	Hand-written as needed.
io	Partial	Hand-written as needed.
io/ioutil	Partial	Hand-written as needed.
os	Partial	Hand-written as needed.
os/exec	Partial	Hand-written as needed.
path/filepath	Partial	Hand-written as needed.
reflect	Partial	Most functionality isn't really even possible in C++.
runtime	Partial	Hand-written as needed.
sort	Partial	Hand-written as needed.
strconv	Partial	Hand-written as needed.
strings	Partial	Hand-written as needed.
sync/atomic	Partial	Hand-written as needed.
sys/unix	Partial	Hand-written as needed.
testing	Partial	Hand-written as needed.
time	Partial	Hand-written as needed.
unicode	Complete	Transpiled.
unicode/utf8	Complete	Transpiled, with passing tests.
unicode/utf16	Complete	Transpiled, with passing tests.
unsafe	Partial	Hand-written as needed.

The goal is to eventually transpile most of these packages, along with their full test suites. Tests can be run via ./gostd test libgostd.a.
