Emacs major-mode for Processing 2.0
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:
git clone https://github.com/ptrv/processing2-emacs
In your .emacs
file, add this:
(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:
(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):
(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:
(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:
(setq processing-output-dir "/tmp")
Optionally it is also possible to set up basic Auto-Complete support to have keyword completion.
(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)
