sapling

A general-purpose compiler (WIP)

Currently it has the analytic power of an Simple LR parser, while its humble synthetic power is provided by a small Lisp-like language called uLisp or micro Lisp. sapling accepts a composite source file, written in fragments of multiple arbitrary languages, with each fragment either being written in one language and translated to another or being written in the highest of a stack of languages and being transitively translated into each successive language in the stack until finally being translated to the lowest one in the stack.

Specification

{terminals}

start -> {starting_symbol};
{nonterminals}

Terminal symbols prefixed with t_gobble__ are not emitted from the lexer to the parser.
