It's time to learn Scheme
Thu, 03 Apr 2008 08:00:00 GMT
Have you ever peeked into one of those bazillion .el files in your Emacs installation's lisp folder and wondered what it meant? Or have you ever looked at a GIMP script .scm file and scratched your head over all the parentheses? Lisp is one of the oldest programming languages still in common use, and Scheme is a streamlined dialect of Lisp. Many universities use Scheme as the language to introduce students to the Computer Science curriculum, and some of their teaching methods are based on the assumption that Scheme is the one language they can count on their students knowing. Even so, many active programmers and system administrators are unfamiliar with Scheme. This article will get you on your way to adding this tool to your developer or sysadmin toolkit.

NAME

       rcs-checkin - check files into RCS

SYNOPSIS

       rcs-checkin [FILE...]

DESCRIPTION

       rcs-checkin is a helper script for checking files into RCS.  This program is distributed with GNU Emacs.

       This  program converts files with an old Emacs-style version history for use with the Emacs 19 version control interface VC, which likes to
       use RCS as its back end.

       For each file to be processed, the script looks for Emacs version files related to it. These files are checked in as deltas, oldest  first,
       so that the contents of the file itself becomes the latest revision in the master.

       The  first line of each file is used as its description.  The file itself is not deleted, as under VC with vc-keep-workfiles at its default
       of t, but all the version files are.

       If an argument file is already version-controlled under RCS, any version files are added to the list of deltas and deleted,  and  then  the
       workfile  is  checked in again as the latest version.  This is probably not quite what was wanted, and is the main reason VC doesn't simply
       call this to do checkins.

       In order to make it easier to use rcs-checkin *, files which are detectably either RCS masters (with names ending in ,v) or  Emacs  version
       files (with names containing ~) are ignored.

OPTIONS

       The program accepts no options.

SEE ALSO

       The  Emacs  version  control  interface is documented in the GNU Emacs manual, which  you  can  read  using Info, either from Emacs or as a
       standalone program.

AUTHORS

       rcs-checkin was originally written by Paul Eggert.  It was revised for use with GNU Emacs VC by Eric S. Raymond.
