Modules

Standard modules are built into the interpreter. Functions can be imported from standard modules using the use operator.

code

The code module offers facilities for inspecting compiled bytecode objects.

• compile returns a compiled lambda value from an expression.
• disassemble prints information about a lambda value to stdout.
• documentation returns the docstring for the named item.
• get-const returns a numbered const value from a lambda object.
• get-value returns a numbered enclosed value from a lambda object.
• module-documentation returns the docstring for the named module.

math

The math module contains mathematical constants and functions.

These functions are identical to their Rust counterparts and include: acos, acosh, asin, asinh, atan, atanh, atan2, cos, cosh, degrees, ln, log, log2, log10, radians, sin, sinh, sqrt, tan, and tanh.

Constants included are: e (Euler's number) and pi.

random

The random module provides access to random number generation functions.

• random returns a random float value in the range [0.0, 1.0).
• shuffle returns a given list in random order.
