- Install Nix https://nixos.org/
- Enable Nix Flakes https://nixos.wiki/wiki/Flakes#Non-NixOS
- Enter a develop shell
nix develop, this might take a while, as it installs the entire GraalVM distribution.
- Build the application
gradle installDist - Enter the installation directory
cd build/install/montuno - Run the launcher
bin/montuno
(unfortunately, I have been developing the project in an IDE until the last minute: due to Gradle issues, the executable really must be executed from that directory)
The launcher supports running entire scripts (bin/montuno ../../../examples/funs.mn),
or individual commands (bin/montuno --normalize '(\x y.x)5'),
or starting a REPL environment (just bin/montuno).
The REPL supports a large set of commands:
- :list - lists currently loaded symbols
- :print - prints out the elaboration state
- :load - discards current state and loads a file
- :reload - discards current state and reloads current file
- :parse - prints out parse tree of an expression
- :raw - prints out the raw inferred term and type
- :elaborate - pretty-prints the result of elaborating an expression
- :normalize - evaluates the expression into a normal form
- :type - prints the inferred type
- :normalType - normalized the inferred type
- :builtin - loads a built-in command (:builtin ALL loads them all, see :list; fix is only available for Truffle)
- :engine - switches the engine between montuno-pure and montuno (Truffle-based)
There is a set of demo scripts in the examples/ directory.
