Installation

Ponyo is a Standard ML library. Ponyo requires Poly/ML to bootstrap but can use MLton to compile Ponyo programs. Ponyo programs should generally work on macOS and Linux.

After Poly/ML has been installed, add the following lines to your ~/.profile:

# Ponyo path settings.
export PONYO_ROOT="/path/to/ponyo/repo"

Then, build Ponyo from git:

$ git clone https://github.com/eatonphil/ponyo && cd ponyo
$ make
$ sudo make install

Standard ML

To follow the Standard ML community in general, check out /r/sml. The /r/sml wiki is a great source of information for getting started in Standard ML. Additionally, someone is always available on Freenode at #sml.
