Slang is a (far from feature-complete) scheme to llvm ir compiler.

Building

To build everything and run all tests, run the following:

meson build
./build_all.sh

You need to have the chicken scheme compiler installed to bootstrap slang.

Examples

To run an example (or your own code), simply use this command:

./test_slang.sh examples/romans.scm ./build/self_hosted.elf example

Features

• Basic primitive such as pair, list, string, char, vector etc.
• Basic constructs such as let, let*, cond, if, set!, begin etc. (letrec and set-car!/set-cdr! are still missing)
• Some of the primitive functions, most importantly display and equal? and things like that
• Basic I/O primitives (at the moment only reading files is possible and only read-char and eof-object? are supported)
• Tail recursion to loop conversion
• Continuations with call/cc
• Foreign calls
• Garbage collection
• Dynamic heap allocation
