Linedit is a readline-style library written in Common Lisp that provides customizable line-editing features, licensed under a MIT-style license.
Linedit uses UFFI for foreign bindings, so it is a least theoretically portable, though REPL-wrapping is currently SBCL specific.
Features
- single-line text reader
- multi-line form reader
- completions on packages and symbols in current image
- completions on directories and filenames
- apropos-word and describe-word
- unlimited undo
- unlimited kill-ring
- unlimited history
- paren matching (not across lines)
- multiple histories
- use in REPL on SBCL
- paging
- fully customizable in CL
- works on Linux, FreeBSD, Darwin
Installation
If you're not yet using Quicklisp, you should be! ...but if you need the tarball, latests release of Linedit can manually be downloaded from here: linedit_latest.tar.gz .
The bleeding edge is available from our Git repo:
git clone git://common-lisp.net/projects/linedit/linedit.git
Installing Linedit at the REPL from .sbclrc
;;; Check for --no-linedit command-line option.
(if (member "--no-linedit" sb-ext:*posix-argv* :test 'equal)
(setf sb-ext:*posix-argv*
(remove "--no-linedit" sb-ext:*posix-argv* :test 'equal))
(when (interactive-stream-p *terminal-io*)
(require :sb-aclrepl)
(require :linedit)
(funcall (intern "INSTALL-REPL" :linedit) :wrap-current t)))
Additionally, to prevent Linedit from causing trouble with Slime, in your .emacs:
(setq inferior-lisp-program "sbcl --noinform --no-linedit")
Terminfo note
Linedit uses terminfo.lisp by Paul Foley, which is currently kept mirrored in the Linedit CVS.
The terminfo interface is distributed available as a separate asdf-installable bundle: Terminfo.
