dali

I do not understand why, when I ask for grilled lobster in a restaurant, I'm never served a cooked telephone. -- Salvador Dalí

dali is a Clojure library for representing the SVG graphics format. It allows the creation and manipulation of SVG files. The syntax used to describe the graphical elements is based on hiccup with a few extensions.

The main advantage of dali is that it provides facilities to perform complex layouts without having to position elements explicitly.

Here's a hello world for dali:

(require '[dali.io :as io])

(def document
 [:dali/page
  [:circle
   {:stroke :indigo :stroke-width 4 :fill :darkorange}
   [30 30] 20]])
(io/render-svg document "hello-world.svg")
;;you can also rasterize directly using Batik:
(io/render-png document "hello-world.png")

Here's a more substantial example of the kind of SVG you can produce with dali without having to specify the exact coordinates to position the elements:

Using dali in your project

Before adding dali as a dependency, please consider that it's still alpha quality and the API and syntax can (and very likely will) change. Just add this to the dependencies of your

project.clj

[dali "1.0.2"]

Or this, to your

deps.edn

dali/dali {:mvn/version "1.0.2"}

Documentation

• Basic syntax -- Start here.
• Compare the examples source to the rendered SVGs.
• Layout -- the main value that dali adds on top of vanilla SVG.
• Pre-fabricated elements
• How-to -- Task-driven documentation, recipes for common tasks.
• Limitations
• Version history

Roadmap

Planned for the future:

• Porting basic functionality to ClojureScript.
• More pre-fabricated elements.
