My bag of miscellaneous Common Lisp utilities. Designed to complement cleanly CL and ALEXANDRIA.

To do:

• MORE TESTS!

• Add type declarations where appropriate

• Some more/better doc

• Use %rel-end %rel-start everywhere in sequence and strings

• macros: add env and use in subtypep and co if needed

• array/hash-table: add :defaults to make-*, like make-pathname, and alias (copy-* src ...) to (make-* :defaults src ...)

  • array: Copy contents only if :initial-element and :initial-contents aren't provided, upgraded-array-element-type are compatible; add :extend-{element,contents} for when new dimensions are larger than :defaults ?
  • hash-table: Use trivial-generic-hash-table, do copy :hash-function

• coerce* pathname <-> string

• queue/deque/stack:

  • conc/nconc ?

• alist/plist/hash-table:

  • coercing between them (in coerce*); means recognizing "fantasy" type alist and plist via EQ
  • map-through for alist/plist (actually replaces translate using hash-table)
  • map[-into], map[-to-list], merge[-into] for alist/plist

• list:

  • sublist version of member (<=> cons-returning versions of search), KMP algo ?
  • nrotate-{left,right}
  • alexandria map-{combinations,permutations,derangements}: wrapper to return the sequences themselves
  • append (instead of nconc) versions of mapcan/mapcon ? mapcap/mapcop ?

• plist

  • map (function (k v) -> (values newk newv))

• array:

  • Add count, [n]substitute, [n]translate, mismatch, reduce, {map,map-into,reduce}-coordinates
  • Add :count where appropriate

• vector:

  • vector-append (adjust -> replace)

• hash-table:

  • Version of copy working with hash-function ?

• sequence:

  • Add {find,position,search}-nth
  • nconcatenate, map[n]cat
  • [n]translate: add start/end, compiler-macro to construct LUT/HT at build time, a way to provide them to avoid rebuilding each time

• clos:

  • Add NIH defclass* with automatic print-object, copy-object and equal-object

• misc:

  • (cond-let var clauses)

• rel-start-end:

  • Optional '(:keyword count elem) to use {position,search}-nth
  • Add function option, now that -any-of is gone

Emacs support:

• To highlight the λ reader macro in Emacs, add

(font-lock-add-keywords
 'lisp-mode
 '(("#[0-9]*λ" . font-lock-keyword-face)))
