This directory contains files for running Gnuplot from within emacs. This package was assembled by Bruce Ravel <firstname.lastname@example.org>. See http://http://xafs.org/BruceRavel/GnuplotMode Almost nothing has changed here since Bruce Ravel's 2002 version. Contents ======== README this file INSTALL thorough installation instructions ChangeLog a log of changes by version number gnuplot.el gnuplot mode for emacs gnuplot-gui.el a GUI for setting command arguments interactively info-look.20.2.el programmer's interface to info files, old version info-look.20.3.el programmer's interface to info files, new version dot.el a short lisp file used by the Makefile gpelcard.tex quick reference card for gnuplot mode (latex) dotemacs example .emacs lines for enabling gnuplot mode Makefile.am \ aclocal.m4 } used by the auotoconfigure system configure.in / Old installation instructions (from before this directory was part of the main gnuplot distribution) Installation ============ 1. Unpack the gnuplot.tar.gz and cd to the gnuplot directory. 2. Type "configure". If configure doesn't work for you, see note 7 below. 3. Run "make". If you use XEmacs, run "make EMACS=xemacs" (or change the EMACS variable to "xemacs" in the Makefile, the run "make"). 4. Move the lisp files to the system site_lisp directory if you are installing as root. If you are installing as a normal user move the .elc files to a place where emacs, i.e. your personal emacs directory. 5. Insert the contents of the `dotemacs' file into your .emacs file or into the system's emacs start-up file to enable gnuplot mode. 6. The function `gnuplot-info-lookup-symbol' looks at the Gnuplot info file that comes with this package or that can be made from the Gnuplot distribution. For that function to work, the file gnuplot.info must be placed somewhere where info can find it, for example /usr/info. A line like this in your .emacs allows you to put gnuplot.info any place convenient: (add-to-list 'Info-default-directory-list "/path/to/file") Wouldn't it be //great// if Emacs had some kind of systematized package installing facility? I think so, too! Oh well.... NOTES ===== 1. The file info-look.el provides the on-line help functionality. Without it, things like on-line help and keyword completion will not work. Using a tool that is a standard part of Emacs is a good idea, but this one gets complicated. This file became part of Emacs with version 20. It changed between 20.2 and 20.3. And it does not come with XEmacs. What's more, the version from 20.2 has a bug and the newer version does not work with Emacs 19. So, this distribution comes with two versions of info-look.el, the version from Emacs 20.2 patched to work correctly and the version from Emacs 20.3. Here's what happens when you run make: a. If you use Emacs 19 or XEmacs 19, then the Makefile will compile the 20.2 version. b. If you use Emacs 20.2 or lower, the Makefile will compile the 20.2 version. c. If you use XEmacs 20 or higher, the Makefile will compile the 20.3 version. d. If you use Emacs 20.3 or higher, the Makefile won't compile any version. 2. The interactive graphical graphical interface to setting command arguments contained in gnuplot-gui.el is experimental. It is incomplete and may make mistakes. Hopefully, you will find it useful. It *requires* that you are using a version of emacs with the widget library installed or that you have installed it yourself. Version numbers in the 20's of Emacs and XEmacs ship with the widget library. For version numbers in the 19's, it can be obtained at http://www.dina.kvl.dk/~abraham/custom/
