cl-introspect-environment 0.1-1.fff42f8

Common Lisp environment introspection portability layer

This library is a small interface to portable but nonstandard introspection of Common Lisp environments. It is intended to allow a bit more compile-time introspection of environments in Common Lisp.

Quite a bit of information is available at the time a macro or compiler-macro runs; inlining info, type declarations, that sort of thing. This information is all standard - any Common Lisp program can (declare (integer x)) and such.

This info ought to be accessible through the standard &environment parameters, but it is not. Several implementations keep the information for their own purposes but do not make it available to user programs, because there is no standard mechanism to do so.

This library uses implementation-specific hooks to make information available to users. This is currently supported on SBCL, CCL, and CMUCL. Other implementations have implementations of the functions that do as much as they can and/or provide reasonable defaults.

Installation

Install cl-introspect-environment 0.1-1.fff42f8 as follows:

guix install cl-introspect-environment@0.1-1.fff42f8

Or install the latest version:

guix install cl-introspect-environment

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
