This adds a unification optimizations API, and uses it to optimize the
embedded provisioner. With these turned on, type unification drops from
around 1m45s to 2.5s which is a 40x speedup.
This commit adds the ability to build a standalone provisioning tool.
This is the first useful public mcl code base as well. It is not
perfect, but does serve as a rough starting point to show what is
possible. In the future as the language and the engine evolve, this will
likely get more elegant, and also grow new features.
To build this, run `make clean && GOTAGS='embedded_provisioner' make`.
To run this, run `mgmt provisioner`.
With the recent merging of embedded package imports and the entry CLI
package, it is now possible for users to build in mcl code into a single
binary. This additional permission makes it explicitly clear that this
is permitted to make it easier for those users. The condition is phrased
so that the terms can be "patched" by the original author if it's
necessary for the project. For example, if the name of the language
(mcl) changes, has a differently named new version, someone finds a
phrasing improvement or a legal loophole, or for some other
reasonable circumstance. Now go write some beautiful embedded tools!
This adds a new entry package that allows embedded programs to exist
inside of mgmt. This took a lot of refactoring to get the API right, but
I think it's incredibly elegant now. There is a chance we tweak things a
bit, but it's a good first start. All-in-one programs are coming soon!
