Code Studio Piskel
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).

Prerequisite
To build Piskel, you need to :
- install node. This repo works best with Node version 10.
- 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
play
grunt play
will:
- build the application in debug mode
- start a server on port 9901 (serving
dest
folder) - open a browser on
http://localhost:9901/?debug
- watch for changes, and rebuild the application if needed
Publishing a new version
This repository depends on a Node version >=7 and < 11. Please use Node >=7 and < 11 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.
If you see an error in the tests around missing python (env: python: Not a directory
), install a version of python 2 (for example, 2.17.8).
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.
