SLP

SLP (Straight Line Programming Language) is a simple running example from Appel's Modern Compiler Implementation in ML, given by the grammar:

<stm>     ::= <stm>;<stm> | <id>:=<exp> | print(<expList>)
<exp>     ::= <id> | <num> | <exp> <binOp> <exp> | (<stm>, <exp>)
<expList> ::= <exp>,<expList> | <exp>
<binOp>   ::= + | - | * | /

This interpreter was mostly written so I could familiarize myself with smlnj's build system.

Usage

To evaluate a source file, simply run Eval.eval "/path/to/file". Print statements will be printed to stdout. To generate an AST, run Parse.parse "/path/to/file".
