Online Playground

The Steel Playground allows you to try Steel out directly from your browser. Visit the Steel Playground at:

https://mattwparas.github.io/steel-playground/dev/

The Steel Playground's environment is as follows:

• Builtin modules are supported and are automatically imported.
• Dylibs are not supported.

Output

The output prints the results of all expressions. Additional information can be printed out with the display and displayln functions.

Bytecode

Bytecode renders the Bytecode that Steel generates from the Steel code. The Bytecode is a low level representation of the code that is executed by the Steel interpretter.

Raw AST

Raw AST exposes the parsed AST. This expands some macros. For example:

(define (foo bar)
  (+ bar bar))

(define baz '(1 2 3))

is actually shorthand for

(define foo
  (λ (bar)
    (+ bar bar)))

(define baz (quote 1 2 3))

Expanded AST

This is similar to the Raw AST but provides more detailed information.
