# Install
Once you have it installed, see the next section on how to create your package definition with `CIEL`.
## With Quicklisp
You need a Lisp implementation and Quicklisp installed.
CIEL is not yet on Quicklisp (but it is on [Ultralisp](https://ultralisp.org)), so clone this repository and load the .asd (with `load` or `C-c C-k` in Slime).
``` example
git clone https://github.com/ciel-lang/CIEL ~/quicklisp/local-projects/CIEL
```
Then, quickload it:
``` commonlisp
(ql:quickload "ciel")
```
and enter the `ciel-user` package, instead of the default `common-lisp-user` (or `cl-user`):
``` commonlisp
(in-package :ciel-user)
```
## With a core image
You need a Lisp implementation, but you don't need Quicklisp.
Build a *core image* for your lisp with all CIEL's dependencies:
``` example
sbcl --load build-image.lisp
```
and use it:
``` example
sbcl --core ciel --eval '(in-package :ciel-user)'
```
TODO: we will distribute ready-to-use core images.
## With a binary. Use CIEL's custom REPL.
You don't need anything, just download the CIEL executable and run its REPL.
TODO: build it on CI for different platforms.
To build it, clone this repository and run `make build`.
Start it with `./ciel-repl`.
You are dropped into a custom Lisp REPL, freely based on [sbcli](https://github.com/hellerve/sbcli).
This REPL is more user friendly than the default SBCL one:
- it has readline capabilities, meaning that the arrow keys work by default (wouhou!) and there is a persistent history, like in any shell.
- it has **multiline input**.
- it has **TAB completion**.
- it handles errors gracefully: you are not dropped into the debugger and its sub-REPL, you simply see the error message.
- it has optional **syntax highlighting**.
It also defines short helper commands:
``` txt
%help => Prints this general help message
%doc => Prints the available documentation for this symbol
%? => Gets help on a symbol <sym>: :? str
%w => Writes the current session to a file <filename>
%d => Dumps the disassembly of a symbol <sym>
%t => Prints the type of a expression <expr>
%q => Ends the session.
```
Note: the documentation is also available by appending a "?" after a function name:
``` txt
ciel-user> (dict ?
```
Syntax highlighting is currently off by default. To enable it, install [pygments](https://pygments.org/) and add this in your `~/.cielrc`:
``` commonlisp
(in-package :sbcli)
(setf *syntax-highlighting* t)
;; and, optionally:
;; (setf *pygmentize* "/path/to/pygmentize")
;; (setf *pygmentize-options* (list "-s" "-l" "lisp"))
```
You can also switch it on and off from the REPL:
``` commonlisp
(setf sbcli:*syntax-highlighting* t)
```
# Use in the REPL and in new packages
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`:
~~~lisp
(defpackage yourpackage
(:use :cl :ciel))
~~~
You can also use `generic-ciel`, based on [generic-cl](https://github.com/alex-gutev/generic-cl/):
~~~lisp
(defpackage yourpackage
(:use :cl :generic-ciel))
~~~
`generic-cl` allows us to define our `+` or `equalp` methods for our
own objects (and more).
