Magic (ed)

Magic (ed) is a tiny editing facility for Common Lisp, where you can directly load, edit, manipulate and evaluate file or file content from REPL.

I find myself often running REPL for various things but lazy enough to engage Emacs/SLIME when I need a small editing work: I'm a UNIX guy and I get used to start vi/vim/emacsclient for writing small throw-away programs.

This package also can be starting point for people who are not accustomed to Emacs or SLIME and would like to continue using their editor with Common Lisp.

Usage

You start it with:

(magic-ed:magic-ed "/tmp/test.lisp")

and it will start editor assigned to EDITOR environment variable. When you are done with editing, save it and quit: magic-ed will load that file and evaluate it. If file saving somehow failed, nothing will be evaluated.

In background, magic-ed will try to use (ed) standard function and will try to obey implementation specific features. For example, on SBCL if sb-ext:\ed-functions** was set, magic-ed will not use environment value.

If you do not want editing file to be evaluated, you use :eval parameter like:

(magic-ed:magic-ed "/tmp/test.lisp" :eval nil)

and file will be only saved. Also, if you would like file content to be returned as escaped string, use :output parameter (accepts only :file and :string):

(setf content (magic-ed:magic-ed "/tmp/test.lisp" :output :string))

Installation

First setup EDITOR environment variable to point to your favorite editor and download magic-ed code (official release or clone it from this repository) and run:

(asdf:load-system :magic-ed)

or if you have Quicklisp:

(ql:quickload :magic-ed)

The code was tested on SBCL, ECL, Clozure CL and CMUCL.
