Espruino Web IDE

A VT100 Serial Terminal as a Chrome Web App (with both syntax highlighted and graphical editors) - designed for writing code on microcontrollers that use the Espruino JavaScript interpreter.

This is a Chrome Web App that uses chome.serial to access your PC's serial port. You can download it from the Chrome Web Store: https://chrome.google.com/webstore/detail/espruino-serial-terminal/bleoifhkdalbjfbobjackfdifdneehpo

It implements basic VT100 terminal features (up/down/left/right/etc) - enough for you to write code using the Espruino. You can also use the right-hand pane to write JavaScript code on the PC, and can then click the 'transfer' icon to send that code directly down the Serial Port.

• Go Here to find the app in the Chrome Web Store

Permissions

This web app requires the following permissions:

• Serial port access : So that it can access the Espruino board via USB/Serial
• Webcam access : So that when you click the little person icon in the top-right of the terminal window, you can overlay the terminal on a live video feed
• Filesystem/storage access : For loading/saving your JvaScript files to your local disk

Using

• Run the Web app
• Click the Help (?) icon, then the Tour button to get a guided tour.

Contributing

Contributions are welcome - especially if they make the Web IDE easier to use for newcomers!

Code Style

• Please stick to a K&R style with no tabs and 2 spaces per indent
• Filenames should start with a lowerCase letter, and different words should be capitalised, not split with underscores

Code Outline

• Core functionality goes in js/core, Plugins go in js/plugins. See plugins/_examplePlugin.js for an example layout
• Plugins/core need to implement in init function, which is called when the document (and settings) have loaded.
• Plugins can respond to specific events using Espruino.addProcessor. For instance you can use Espruino.addProcessor("transformForEspruino", function (data,callback) { .. }) and can modify code before it is sent to Espruino.
• Icons are added using Espruino.Core.App.addIcon and are generally added from JsvaScript file that performs the operation
• Config is stored in Espruino.Config.FOO and is changed with Espruino.Config.set("FOO", value). Espruino.Core.Config.add can be used to add an option to the Settings menu.
• Annoyingly, right now plugins still have to be loaded via a <script> tag in main.html
