Extempore Emacs Mode

A major mode for editing Extempore code. See the Extempore project page at http://github.com/digego/extempore for more details.

Installation

Available through MELPA:

M-x package-install RET extempore-mode RET

If you don't want to get it from MELPA, just download the file and use package-install-file (or even just load).

(package-install-file "/path/to/extempore-mode.el")

Configuration

There are several config variables to tweak, but in most cases the defaults will be ok if you're just starting out. If you want to see them, hit M-x customize and look in the extempore group.

The only thing you might want to set out-of-the-box is extempore-path, so that you don't have to answer the "directory" prompt every time you call switch-to-extempore. You can do it through customize or set it directly in your init file like so:

(setq extempore-path "/path/to/extempore/")

Usage

The most important commands are

M-x extempore-connect (default keybinding C-c C-j)

Connect the current extempore-mode buffer to a running Extempore process---this is necessary to begin sending code for evaluation. If called with a prefix arg, prompt for a host & port number to connect to, otherwise use the values of extempore-default-host (default "localhost") and extempore-default-port (default 7099).

An Extempore process may have multiple connected buffers, and each buffer can be connected to multiple Extempore processes.

M-x switch-to-extempore (default keybinding C-c C-z)

Switch to the Extempore process buffer running in Emacs. If not currently running, prompt to start one.

The most useful command for day-to-day use is:

M-x extempore-send-dwim (default keybinding C-M-x)

which sends the Extempore top-level definition under point (or current region, if active) to the Extempore process connected to the current buffer.

Caveats

extempore-mode requires Emacs 24, because it inherits from prog-mode (via lisp-mode)
