Pushed to pdo/rpl-tools
f083adb Changed to use Git version control.
RPL-TOOLS ========= Useful Emacs tools for working with RPL source code, the native language of HP48/49/50-series calculators. In its present state really only provides `sysrpl-mode' for editing SysRPL source files. This mode implements syntax highlighting and documentation lookup, using data extracted from Carsten Dominik's ``entries.db'' system RPL entries database. To install rpl-tools, clone this Git repository to somewhere in your Emacs `load-path' with git clone http://bitbucket.org/pdo/rpl-tools then add the following to your ~/.emacs file (require 'rpl-tools) (add-to-list 'sysrpl-mode-hook 'eldoc-mode) where the latter command activates the minor eldoc-mode in sysrpl-mode. This causes a stack-effect diagram to be displayed in the minibuffer whenever the cursor is on a SysRPL word. More info can be displayed with the `sysrpl-apropos-thing-at-point' command, bound to C-c C-a by default, which pops up another window with any extra information available for the supplied word (by default the one under the cursor). Note: sysrpl-mode is not bound to any particular file extension by default, so to enable it for any particular buffer you will have to issue the command M-x sysrpl-mode to place the current buffer into sysrpl-mode. Alternatively you can use the standard Emacs file local variable feature to embed the mode name into the first line of a file. See the included example in examples/timedone.s for details. Also, be aware that this code was written with Gnu Emacs 24.3 so I may have used features not found in earlier versions. If you see strange errors when you try to use it, check your Emacs version with M-x emacs-version and be prepared to upgrade your Emacs if necessary.
