Quil examples

Examples of Quil sketches.

Check src/quil_sketches folder and it's subfolders. Each .clj file is a separate sketch. Some of them shows particular Quil feature and some of them are simply beautiful animations. You can start with running them one by one and studying their sources.

How to run examples

Clone repo with examples to you machine:

git clone https://github.com/quil/quil-examples.git

Using the Clojure CLI

Install clojure, and from within the quil-examples repo, start a repl and execute a sketch by evaluating a namespace:

$ clj -M --repl
Clojure 1.11.1
user=> (require 'quil-sketches.gen-art.01-cross-with-circle :reload)

Alternatively, sketches with a -main function in the namespace can also be executed like:

$ clj -M -m quil-sketches.graphics

(ESC to close a sketch window, and ctrl-D or ctrl-C will quit quickly after the sketch displays).

Or with commandline arguments to the -main function:

$ clj -M -m quil-sketches.automata 30

Finally, -X can be used to invoke a specific function:

$ clj -X quil-sketches.key-capture/-main

Using lein REPL

Start REPL:

lein repl

Require selected sketch to run it:

user=> (require 'quil-sketches.gen-art.01-cross-with-circle :reload)

Note:

• you should prefix sketch namespace with single quote: 'quil-sketches.gen-art.01-cross-with-circle
• :reload option is needed if you want to run it several times. Otherwise sketch won't run on second and subsequent require calls.

Using lein run

Use following command to run selected sketch:

lein run -m quil-sketches.gen-art.01-cross-with-circle

When you close sketch JVM won't exit, so you need to do it manually e.g. using Ctrl+C combination.

Using LightTable

Start LightTable.
Open folder containing the project:

File -> Open folder

Open file containing sketch and evaluate it using following keys combination:

Ctrl+Shift+Enter

Using emacs

Open file with sketch:

emacs src/quil_sketches/gen_art/01_cross_with_circle.clj

Start cider:

M-x cider-jack-in

It may prompt for which command to use, either lein or clojure-cli should work, depending on which tools are installed locally.

Evaluate opened file:

C-c C-k

Sketch will open. You can run other sketches by opening their files and evaluate their contents via C-c C-k

How to create your own sketch

It is simple. You can either modify existing sketch or create new one. To create new sketch first you need to create sketch file e.g. src/quil_sketches/my_super_sketch.clj and use some existing sketch as initial template (don't forget to modify namespace to quil-sketches.my-super-sketch).

Happy hacking!
