Install

Once you have it installed, see the next section on how to create your package definition with CIEL.

With a binary.

You don't need anything, just download the CIEL executable and run its REPL.

we provide an experimental binary for Debian systems: go to https://gitlab.com/vindarel/ciel/-/pipelines, download the latest artifact, unzip the ciel-v0.zip archive and run ciel-v0/ciel.

To build it, clone this repository and run make build.

Start it with ./ciel.

You are dropped into a custom Lisp REPL.

To run a .lisp file as a script, give it as argument:

ciel myscript.lisp

See the next sections for usage documentation.

You need a Lisp implementation and Quicklisp installed.

CIEL is not yet on Quicklisp (but it is on Ultralisp), so clone this repository and load the .asd (with load or C-c C-k in Slime).

git clone https://github.com/ciel-lang/CIEL ~/quicklisp/local-projects/CIEL

Then, quickload it:

(ql:quickload "ciel")

and enter the ciel-user package, instead of the default common-lisp-user (or cl-user):

(in-package :ciel-user)

You need a Lisp implementation, but you don't need Quicklisp.

Build a core image for your lisp with all CIEL's dependencies:

sbcl --load build-image.lisp

and use it:

sbcl --core ciel-core --eval '(in-package :ciel-user)'

Note: you must build the core image, we can't distribute ready-to-use core images, it must be built on your machine.

On the REPL, enter the ciel-user package instead of cl-user (,in-package RET ciel-user).

Use CIEL in your own packages by use-ing it in addition of cl:

(defpackage yourpackage
  (:use :cl :ciel))

You can also use generic-ciel, based on generic-cl:

(defpackage yourpackage
  (:use :cl :generic-ciel))

generic-cl allows us to define our + or equalp methods for our own objects (and more).
