cl-heredoc - Common Lisp reader heredoc dispatcher

cl-heredoc is an implementation of "here documents" that allow the user to embed literal strings into code or data without any need for quoting, something that is missing in both ANSI CL and popular implementations.

cl-heredoc is completely written in Common Lisp and licensed under the GPLv3+. Please see the file COPYING in the top-level directory of the distribution tarball or the online version if you didn't receive a copy along with this file.

Usage

cl-heredoc primarily exports a single function, READ-HEREDOC, that is meant to be used with the CL reader by attaching it to a dispatch character, e.g.

CL-USER> (set-dispatch-macro-character #\# #\> #'cl-heredoc:read-heredoc)
CL-USER> #>eof>Write whatever (you) "want",
  no matter how many lines or what characters until
the magic end sequence has been reached!eof

Will read everything starting after #>eof> until the given sequence, here eof, is found and return the result as a string. The enclosed text is not subject to any kind of evaluation and needs no quoting.
If used in a non-interactive fashion, i.e. outside the REPL, an error will be signaled if EOF is reached.

The underlying function READ-UNTIL-MATCH may also be used directly: It takes two arguments, a stream and a termination string and will read from the stream until the terminating sequence is found. Everything read so far excluding the terminator is returned as a string.
