Common Lisp reader heredoc dispatcher
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.
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.
