# Emacs major-mode for Processing 2.0

[![MELPA](http://melpa.org/packages/processing-mode-badge.svg)](http://melpa.org/#/processing-mode)

Based on Rudolf Olah's version and modification by Bunny Blake.

https://github.com/emacsmirror/processing-mode

https://gist.github.com/4083326

The snippets are taken from Sublime Text 2's Processing plugin and converted to yasnippet snippets.

## Installation

The easiest way is to install the ELPA package from MELPA with `M-x

package-install RET processing-mode`. All dependencies are automatically

installed.

## Manual installation

To install `processing-mode` manually, clone the repository:

```lisp

git clone https://github.com/ptrv/processing2-emacs

```

In your `.emacs` file, add this:

```lisp

(add-to-list 'load-path "/path/to/processing2-emacs/")

(autoload 'processing-mode "processing-mode" "Processing mode" t)

(add-to-list 'auto-mode-alist '("\\.pde$" . processing-mode))

```

Add the following to set up processing snippets for [yasnippet][1]:

```lisp

(autoload 'processing-snippets-initialize "processing-snippets" nil nil nil)

(eval-after-load 'yasnippet '(processing-snippets-initialize))

```

## Configuration

Set variables in `.emacs` or with `customize-group RET processing RET`

(this works only after `processing-mode` has been loaded):

```lisp

(setq processing-location "/path/to/processing-java")

(setq processing-application-dir "/path/to/processing-application-dir")

(setq processing-sketchbook-dir "/path/to/processing-sketchbook-dir")

```

For example, on Mac the default settings are the following:

```lisp

(setq processing-location "/usr/bin/processing-java")

(setq processing-application-dir "/Applications/Processing.app")

(setq processing-sketchbook-dir "~/Documents/Processing")

```

Usually when you run a processing sketch, the build files are generated

in a sub-directory called `output` in the current sketch directory. It

is also possible to set the `processing-output-dir` to another

directory:

```lisp

(setq processing-output-dir "/tmp")

```

Optionally it is also possible to set up basic [Auto-Complete][2]

support to have keyword completion.

```lisp

(defun processing-mode-init ()

  (make-local-variable 'ac-sources)

  (setq ac-sources '(ac-source-dictionary ac-source-yasnippet))

  (make-local-variable 'ac-user-dictionary)

  (setq ac-user-dictionary (append processing-functions

                                   processing-builtins

                                   processing-constants)))

(add-to-list 'ac-modes 'processing-mode)

(add-hook 'processing-mode-hook 'processing-mode-init)

```
