A toy language I designed to be as easy as possible to implement. Reminiscent of lisp, läspa uses Reverse Polish Notation for basic arithmetic and for function calls. With a basic interpreter implemented, I plan to implement a compiler with the help of LLVM and plain machine-code generation.
shell
cargo install laspa
You will need the llvm toolchain to build the executable. Clang is also used for linking.
shell
brew install llvm && export LLVM_SYS_160_PREFIX='/usr/local/opt/llvm@16'
See this test file for example syntax. ``` A simple Lisp-like language built with Rust
Usage: laspa [OPTIONS]

-O, --optimization-level
I was reading an article on the fastest implementation of a binary search algorithm.
I saw llvm
and thought to myself: "Hmm, wouldn't it be interesting to make a language." The rest is history.
The lex
, parse
, and eval
functions are the meat of the execution of the language. Those familiar with language
development will recognize those names. llvm.rs
is crucial to generating and compiling the IR for LLVM executations.
