Aydede

Project Status: WIP – Initial development is in progress, but there has not yet been a stable, usable release suitable for the public.

Aydede is an implementation of the R7RS small Scheme language on top of the LuaJIT runtime. It makes use of LPeg for specifying the grammar and follows the general design of the metacircular interpreter described in "Structure and Interpretation of Computer Programs".

What makes Aydede unique is how it handles interpretation. The interpreter is parameterized at runtime based on the command-line arguments provided. This means that, for example, passing the --ast argument will tell Aydede to use the AST-Printing interpreter that only dumps the AST to STDOUT and then quits.

Building

Both LuaJIT and LPeg have been vendored in with the project. LuaJIT is vendored as a git submodule, so before building you will need to check out the correct version of LuaJIT by running git submodule update --init. Also, the Makefile assumes that you have Clang installed to compile the C code. If not, you may need to edit the CC line in the Makefile.

From there, building should be as simple as running make.
