Windows needs some env vars contain semicolon instead of colon as separator

`esy` uses `realpath` from `stdlib` when ejecting. (See [here](https://github.com/reasonml/esy/blob/esy/src/esy/buildEjectCommand/index.js#L400-L410)) According to @jordwalke it fails on `msys2`. IMO we should add an `#if` in our `realpath.c` and use [their implementation](https://sourceforge.net/u/earnie/msys2/msys2/ci/a949093a5e10123e445184b0a20e19e93e0b0658/tree/newlib/libc/sys/linux/realpath.c) if...

We should at least work well on winbash, even if we don't produce windows native executables yet.

Allow multiple version of a package in the same dependency tree

1

We need to support `buildTimeDependencies` for that but there's a workaround suggested by @jordwalke: > So let's say I have two versions of Reason. And you're building the two separate...

Publish m4 and use it instead conf-m4 for opam packages

1

opam package `conf-m4` checks if `m4` is available on a system. Instead we can package `m4` and use it instead. https://github.com/esy-ocaml/m4 The problem is that m4 build time is around...

[MID PRI][Good First Task] Stop augmenting PATH for irrelevant packages.

2

I previously [commited](https://github.com/reasonml/esy/commit/0becd335c8a48a46945039d48c3815a7e9ec98be) a change that prevents irrelevant packages from populating any of the variables for install/bin/man etc. Currently, however, all of those packages still populate the `PATH`, which means...

[HIGH PRI] Generate and publish opam packages to pure npm.

11

The current [yarn fork](https://github.com/reasonml/esy) is nice because it has some built in resolving to fetch opam packages even though they don't have package.jsons. We can then use that project to...

[MED PRI] Constraint solver that generates shrinkwrap.

1

- Constraint solver that generates `shrinkwrap.json`. - Constraint solver that generates yarn lockfile (stretch goal, maybe not needed).

[HIGH PRI] Detect if some file changed in "local dependency"

8

Right now for local dependencies (symlinks or local file:// dependencies) `esy build` will rebuild them every time even if nothing changed, because we don't detect if anything changed. Instead, we...

It would be nice to get some clean, pure logic based tests that don't hit the network. @andreypopp Maybe your intermediate representation would be a convenient testing layer?
