This extends `gol` "backward-inference" typechecking to thread through cores. Recall that `gol` is used exclusively for receiving more specific error messages; these changes should have no effect on programs which already compile successfully. Before, this would type-fail on the second `|%`. ``` !: ^+ ^? |% ++ foo *@ud -- |% ++ foo ?: =(1 1) 2 %foo -- ``` With these changes, it gives a mint-nice at `%foo`. It will also give you explicit errors if you have the wrong number/names of arms, including which arms it expects. This is becoming much more important with static gall, since it's the first time we've used core subtyping so extensively and in userspace. |

Urbit
A personal server operating function.
The Urbit address space, Azimuth, is now live on the Ethereum blockchain. You can find it at
0x223c067f8cf28ae173ee5cafea60ca44c335fecb
orazimuth.eth
. Owners of Azimuth points (galaxies, stars, or planets) can view or manage them using Bridge, and can also use them to boot Arvo, the Urbit OS.
Install
To install and run Urbit, please follow the instructions at urbit.org/docs/getting-started/. You'll be on the live network in a few minutes.
If you're interested in Urbit development, keep reading.
Development
Urbit uses Nix to manage builds. On Linux and macOS you can install Nix via:
curl https://nixos.org/nix/install | sh
The Makefile in the project's root directory contains useful phony targets for building, installing, testing, and so on. You can use it to avoid dealing with Nix explicitly.
To build Urbit, for example, use:
make build
The test suite can similarly be run via a simple:
make test
Note that some of the Makefile targets need access to pills tracked via git LFS, so you'll also need to have those available locally:
git lfs install
git lfs pull
