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.
