sigil

a lisp oxide

about

sigil is a lisp intended to bridge the gap between "low-level" code written in Rust and places where "high-level" code is desired.

if you have a question about how sigil works as a language, you should assume it has Clojure semantics.

this crate provides an interpreter meant to be embedded into other Rust code. an example of such an embedding can be found with the repl under /examples.

contributing, etc.

contributions are very welcome! if you are keen to join, i'd suggest messaging me on twitter or somewhere to see the current status.

usage

To open a repl:

cargo run --features repl

To run a file:

cargo run --features repl -- from-file $FILE_PATH

status

things are still very much a work-in-progress still. the "core" interpreter is written but there are several features worth adding:

• tools for interop with Rust
• metadata
• namespaces
• language-level features
  • other primitives
  • "collections are functions of their keys"
  • argument destructuring
  • rich fn macro
  • some reader macros e.g. #( %1 )
• precise errors, in the style of Rust
• GC and related memory story

i have vague plans to accelerate computation with a web-assembly VM at some point.
