read-macros
:read-macros is a library of useful read macros for CL.

It includes

  • an extensible syntax (similar to #S)
  • conditional reads
  • conditional reads based on *features* (similar to #+ and #-)
  • stateful block reads (similar to CPP's #if/#elif/#else/#endif)
  • lexical read manipulation (e.g. bind *read-base*)
  • here documents [fullfilling heredocs in lisp?]

The initial release is available as a tarball or a zipfile.


cl-syntax-sugar is a similar library.
