This is the compilation repository for Processing.js, used in building theprocessing.js library from a series of Node.js flavoured commonjs modules, rather than existing as one large file as was the case in all versions up to and including 1.4.1 (released august 2012) .

note: this is not the repository for Processing, the language and IDE. Processing itself is hosted over athttps://github.com/processing/processing. This is also not where to file bugs or ask questions about the "JS mode" that can be used with Processing, that project is hosted over athttps://github.com/fjenett/javascript-mode-processing

Processing.js adheres tosemver style versioning, with the current version being 1.6.0 (released July 9th, 2016)

There is currently no one working on, or maintaining, this codebase on a regular basis, so if you think you'd like to contribute to Processing.js, to bring it back in line with Processing's current API, and take advantage of the various APIs that have become available in browsers since Processing.js slowed down, we'd love to hear from you!

File an issue to say that you'd like to help out, and we can find some good places for you to get started.

bower install Processing.js

npm install processing-js

Simply grab theprocessing.js orprocessing.min.js files, include them as script on your webpage, and you're all set. Seetest.html for a simple example of using Processing.js on your pages.

Clone this project using git, and ensure you havenode.js installed. After cloning, install the require node packages usingnpm install in the processing-js directory. Modifying the code and building your ownprocessing.js andprocessing.min.js files is then a fairly straight forward process. Modify the code as much as you want or need, then:

1. Lint:$> grunt
2. Test:$> node test

If step 1 gives you a "grunt: command not found" or similar error, runnpm install -g grunt-cli to make sure grunt is globally installed as CLI command. If step 1 does not throw any errors, step 2 will run the Processing object through a battery of tests. Once the browser reference tests start, yourprocessing.js andprocessing.min.js have been successfully built.

The test script also accepts the following optional arguments:

• --test=testfile.pde runs one specific test
• --nobuild does not build Pjs if all tests pass
• --failonerror terminates the run if any error occurs.
• --noref will not start a server process and a browser for doing ref testing.
• --noautoref will start a server and a browser for ref testing, but doesn't auto-start the tests.

You can also perform the post-unit-test steps manually:

• Build processing.js:$> browserify build.js -o processing.js
• Minify processing.js:$> node minify
• Run test server:$> node server

With the test server is running, the following urls are good to know:

• http://localhost:3000 - vanilla example page
• http://localhost:3000/ref - reference testing page
• http://localhost:3000/perf - performance testing page
• http://localhost:3000/processing-helper.html - utility page for converting/running Processing code
