Setup

Setting up things on OS X is easy thanks to Homebrew. Simple run the following command:

$ brew install smlnj rlwrap

Usage

We'll make use of the CM module for building the projects. To use it you need a sources.cm file. Then run the following commands.

Due to a bug in MLex you currently need to manually change the generated tiger.lex.sml to val initPos = 1 instead of val initPos = 2. This only needs to be done after cahnging the tiger.lex file.

$ rlwrap sml sources.cm
