Adds type synonym declarations to the language, like so: ``` tydef Maybe a = Unit + a end def lookdown : Cmd (Maybe Text) = scan down end > lookdown it2 : Maybe Text = inl () ``` `tydef` behaves very similarly to `def` except that it defines a new (parameterized) type instead of a new term. Note that higher-kinded types are not yet supported; for example we cannot say `tydef Foo f = Unit + f Int` (in fact this would be a syntax error since type variables cannot be at the head of an application). However there is nothing stopping us from adding that in the future; I just wanted to keep things simple for now. If you know of any scenario code that would be a good candidate for using type synonyms, let me know --- it would be nice to update a few scenarios as a better stress test of type synonyms before merging this. Closes #153. |

Swarm
Swarm is a 2D programming and resource gathering game. Program your robots to explore the world and collect resources, which in turn allows you to build upgraded robots that can run more interesting and complex programs. More info can be found on the Swarm website.
Contributing
See CONTRIBUTING.md for information about various ways you can contribute to Swarm development!
Building
If you just want to play the game, head over to the Swarm website for installation instructions. If you want to build Swarm from source (e.g. in order to contribute, or to test out the latest bleeding-edge unreleased features), read on.
-
Clone the Swarm repository, e.g.
git clone https://github.com/swarm-game/swarm.git -
If you don't already have the
cabaltool:-
Get the
ghcuptool, a handy one-stop utility for managing all the different pieces of a Haskell toolchain. -
Use
ghcupto install a supported version of GHC:ghcup install ghc 9.6.4 -
Use
ghcupto installcabal:ghcup install cabal
-
-
Now use
cabalto build and run Swarm:cd /path/to/the/swarm/repo cabal run -O0 swarm:exe:swarm(Note that we recommend turning off optimizations with
-O0since they don't seem to make much difference to the speed of the resulting executable, but they make a big difference in compilation time.) -
Go get a snack while
cabaldownloads and builds all of Swarm's dependencies. -
