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
