RISP

Warning: The language is a work in progress. It's lacks many features and might not be stable.

RISP is an interpreted LISP-like language. It's written in Rust.

Features

Checked entries have been implemented.

  • Integers and Strings
  • Floats
  • Better error reporting
  • Operators
  • Variables
  • if-else expressions
  • while and for loops
  • Functions
  • Macros
  • Classes

Usage

Rust must be installed for compiling the code. The latest version is recommended. Installing cargo is also recommended.

  1. Clone the repo

    git clone https://github.com/shivrm/risp

    GitHub also lets you download the source code as a ZIP.

  2. Navigate to project folder

    cd risp

  3. Build and run with cargo

    • Run without any arguments to start the REPL. This lets you interactively run statements - one at a time.

      cargo run

    • To execute code from a file, give the file path as a command-line argument. Replace <file> with the path to the file:

      cargo run <file>

    • Giving bench as a command-line argument will benchmark the lexer. Note that this might be performance intensive.

      cargo run bench

Examples

See scripts/example.risp for an example RISP script. Run it with

cargo run scripts/example.risp
