lfe_cl(3) lfe_cl(3) NAME lfe_cl - LFE Common Lisp interface library SYNOPSIS This module provides a set of Common Lisp functions and macros for use in LFE. The definitions closely follow the CL definitions and won't be documented here. DATA TYPES The boolean values used here are the standard LFE true and false and NOT the Common Lisp values. EXPORTS Boolean conversion functions make-lfe-bool cl-value make-cl-bool lfe-bool Control structures do vars (end-test result) body [macro] The value of body is bound the variable do-state which can be used when updating vars and in the end-test. This is the only way to get a value out of the body. mapcar function list maplist function list mapc function list mapl function list Symbol functions symbol-plist symbol symbol-name symbol get symbol pname get symbol pname default getl symbol pname-list putprop symbol value pname remprop symbol pname Atoms (symbols) in LFE don't have property lists associated with them. However, here we have experimented with having a global ETS table lfe- symbol-plist which associates an atom with a property list. This is very unLFEy, but quite fun. Property list functions getf plist pname getf plist pname default putf plist value pname remf plist pname get-properties plist pname-list The function putf/3 does not exist in Common Lisp but is included to complete the operations on property lists.

Currently this of- fers Common Lisp predicates, but may include other useful macros and functions in the future. The provided predicate macros wrap the vari- ous is_* Erlang functions; since these are expanded at compile time, they are usable in guards.
