Here's descriptions of all the (informal) categories of operators provided by Loopless. See Reference, for comprehensive documentation of all these utilities. See Quick Reference, for a table showing at a glance all the operators.
mapcarand friends. They are analogous to
mapl/maplist/mapconfor iteration (and possible accumulation of values into a list) over alists, plists, vectors and integers. See MAPCAR-like Functions.
dolistand friends. They are analogous to
dotimes, but for the conses of a list, alists, plists and vectors. There's also
dotimes*, which is just like
dotimesbut without an iteration variable. See DOLIST-like Macros.
with-collectors, provide easy and efficient collection of values into one (or multiple) list(s). They were copied from the
cl-utilitieslibrary but I added support for
nconc-style accumulation. See Collection Macros.
forclause to step variables in conjunction with any looping construct whatsoever. “for-as-arithmetic” and “for-as-equals” are supported. See FOR*.
tagbodyrepeatedly while a condition holds true. See WHILE*.
cl-utilitieslibrary and is included in Loopless because it's very useful for the
mapcar-like functions, in particular. See COMPOSE.
