cl-heredoc - Common Lisp reader heredoc dispatcher
cl-heredoc is an implementation of "here documents" [1] 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+[2]. Please see the file COPYING in the top-level directory of the
distribution tarball or see the link at [2] if you didn't receive a copy along
with this file.
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.
