Using from.std.* errors out when compiling to WebAssembly

[skoppe]

When using from.std.xxx the from template does a import std;. The std/package.d publicly imports whole of phobos. The system.d module from phobos - which is unaware of WebAssembly - errors out with Error: static assert: "Unknown OS.".

Now, this is actually an issue with phobos. But I am just posting it here so that you are aware of the issue.

I have PR's ready for druntime and phobos to support WebAssembly, which will resolve this issue. But it is going to take some time.

Thanks for the heads up! 🙇

@skoppe what's the status on your PRs. As a work around we could have bolts not use "from" for std packages if it's causing problems.

The pr's aren't quite there yet. I first want to experiment with them some more.

I am still using optional 0.16.x, but I have a good workaround for the @disabled stuff, so there is no urgency.

Last 2 weeks I had to focus on some other things, but I hope to continue working on the PR's this week.

Since there aren't many people using optional in a non x86 arch, I don't mind you closing this issue.

Just made a pull request #5 to replace std.from with bare imports. The pr's for phobos are going to take a little longer and I really want to update spasm to the latest version.
