Project's home: http://www.hexstreamsoft.com/projects/macro-level/ MACRO-LEVEL is an embarassingly trivial convenience macro that saves on indentation while being more concise and direct. (macro-level ...) == ;; Canonical indentation. MACRO-LEVEL saves 11 spaces. (macrolet ((m () ...)) (m)) == ;; "Miser" indentation. MACRO-LEVEL saves 5 spaces. (macrolet ((m () ...)) (m)) When used as part of a macroexpansion, MACRO-LEVEL also conveniently relieves the macro implementor from naming and using a gensym for the one-shot macro when compared to writing out a MACROLET by hand, in addition to the other advantages. To use MACRO-LEVEL, simply (macro-level:macro-level ...) after loading the ASDF system, as this macro is not used that often and the length won't have any effect on the indentation: (macro-level:macro-level ...) VS (macro-level ...) Simply (:import-from #:macro-level #:macro-level) in your DEFPACKAGE if you prefer the latter form. Don't (:use)! Support could eventually be added to Slime so that interactive macroexpansion of MACRO-LEVEL calls with C-c C-m (slime-expand-1) would show the same expansion as interactively macroexpanding (m ...) after (defmacro m () ...), assuming the lexical context is not important.
