Code Studio Piskel

Travis Status

This is a custom version of the excellent Piskel Editor by @juliandescottes and @grosbouddha, designed for embedded use with the Code.org Code Studio learning platform. For more information on using or developing Piskel, please see the main repository.

This project is published on npm as @code-dot-org/piskel.

Using this package

Install the package from npm:

npm install @code-dot-org/piskel

This will install the release build of Piskel to node_modules/@code-dot-org/piskel. The application root is at node_modules/@code-dot-org/piskel/dest/prod. You can run the static version of Piskel by opening index.html in that folder.

A piskel-root utilty is also installed at node_modules/.bin/piskel-root that prints the absolute path to the application root. It's recommended that you depend on this utility in any build scripts to be resilient against future changes to the internal layout of the Piskel package.

Local Development Setup

Note: To run local integration tests you should install CasperJS 1.0.2 (not included as a dependency in this repo) and make sure it has access to PhantomJS 1.9.2 (downloaded to node_modules/.bin on npm install but not necessarily in your PATH).

Contributing

Prerequisite

To build Piskel, you need to :

  • install node
  • install grunt-cli npm install grunt-cli -g.
  • run npm install

Grunt build targets

serve

grunt serve will:

  • build the application
  • start a server on port 9001 (serving dest folder)
  • open a browser on http://localhost:9001
  • watch for changes, and rebuild the application if needed

Note: Using grunt serve --force

  • If you try grunt serve and it is aborted due to warnings do grunt serve --force

Note: If you make new changes to JSON files, use grunt build-dev

  • If you added new strings to the JSON files in the locales directory and you want to see the changes, you need to do grunt build-dev

Publishing a new version

This repository depends on a Node version >=7. Please use Node >=7 when building and updating new releases of this Piskel to NPM.

To publish a new version to npm switch to the master branch, use npm login to sign in as an account with access to the @code-dot-org scope, then npm version [major|minor|patch] for the appropriate version bump. This will do the following:

  • Run linting and tests to verify your local repo.
  • Rebuild the release package.
  • Bump the version, adding a corresponding commit and version tag.
  • Push the commit and tag to github.
  • Publish the new release package to npm.

Internationalization (i18n)

The Piskel UI can support different languages by setting the window.piskel_locale to a four letter locale code, i.e. en_us, es_mx, etc.

The available strings are in i18n/locales directory and each locale has its own file. For example: en_US.json where en is English and US is United States Note that en_US.json should contain all available strings because this is the locale other languages will fallback to if a translation from English doesn't exist.

The strings for all the languages are loaded into window.piskel_locales and the language specific strings can be accessed using the four letter locale code. For example:

var i18n = window.piskel_locales[window.piskel_locale];
console.log(i18n.simplePenDrawingTool());

The JSON files are converted to Javascript files during the build in tasks/build-i18n.js. The MessageFormat library is used to convert the static JSON strings into Javascript functions so dynamic content can be injected into the strings.
