Overview ¶
Microlisp is a Lisp interpreter. It's primarily a toy, and is a work in progress.
Its initial definition is based on McCarthy's "A Micro-Manual for Lisp: Not the Whole Truth".
Environments ¶
An environment is a value that maintains mappings between a symbol and a value. If an environment has a parent, then bindings are inherited.
The evaluator typically provides an environment implicitly.
Variables.
system-environment Primitives are bound in this environment. user-environment User definitions are bound here, and it inherits system-environment.
Functions.
environment-bindings The environment's bindings represented as an association list.
Errors ¶
The error system is very simple. If an error value is thrown, it stops the current evaluation, and is handled and printed by the REPL.
Functions ¶
error Raise an error value with a message composed of its arguments. ignore-errors Invoke a function, trapping any errors thrown as a return value.
