Try changing the handler to modify the data before returning it. The data was passed to Atom and simply returned as-is.
Devdocs client code#
(It's very easy to add this code to julia-client's activate function if you want to try this out.)Ĭalling the following from the REPL: echo(Dict(:a=>1, :b=>2)) It's also possible for Julia to wait for a response from Atom, using the rpc function.

Handlers are defined on the Atom side as follows: client.handle 'log', (args.) -> Julia has a similar mechanism to talk to Atom via the function type(args.) (You'll want to use a type other than eval to avoid clashes with actual evaluation.) Sending messages from Julia This approach is exactly how Atom gets evaluation results, autocompletion and more from Julia – so it's easy to find more examples spread throughout the julia-client and Atom.jl source code.Īs a first project, try implementing an Atom command (see the Atom docs) which sends this message to Julia, as well as adding the Julia handler above to Atom.jl. This call sends the eval message, pulls the result field out of the returned JSON, and displays the result, 4, in the console. We don't need to change anything on the Julia side to accomplish this we can just use the rpc function from JS: client.rpc('eval', '2+2').then (result) => Often we want to do something with that return result in Atom – in this case, we'd like to display the result. It simply evaluates whatever it's given and returns the result – in this case, 4. This is a very simplified version of the eval handler that you can find in the Atom.jl source code. On the Julia side, we need to set up a handler for this message, which happens as follows: handle("eval") do code For example, on the Atom side messages are sent in CoffeeScript as follows: client.msg 'eval', '2+2' The handler then takes some action and returns data to the original sender. Sending messages from AtomĬommunication works by sending messages with an appropriate type on one side and registering handlers for that type on the other. However, the details of those files aren't particularly important – you only need to understand the communication API, which we'll go over here. The code handling low-level communication is kept in ffee and comm.jl. Messages are JSON objects, with a type header to tell the receiver how the message should be handled. When Julia starts it connects to Atom over a TCP port, and from that point on Julia and Atom can each send messages to each other. Hooks were introduced in React Native 0.59., and because Hooks are the future-facing way to write your React components, we wrote this introduction using function component examples.Juno works by booting a Julia client from Atom. But since the introduction of React's Hooks API, you can add state and more to function components. Originally, class components were the only components that could have state. With React, you can make components using either classes or functions.

(If you are a web developer, you may already have a local environment set up for mobile browser testing!) Function Components and Class Components Optionally, if you want to setup a local development environment, you can follow our guide to setting up your environment on your local machine and paste the code examples into your App.js file there. Go ahead and try changing the "Try editing me!" text above to "Hello, world!" The code is live and editable, so you can play directly with it in your browser.
Devdocs client android#
It’s a handy tool created by Expo to embed and run React Native projects and share how they render in platforms like Android and iOS. This introduction lets you get started immediately in your browser with interactive examples like this one:

While we do our best to assume no prior knowledge of React, Android, or iOS development, these are valuable topics of study for the aspiring React Native developer. If you’re new to JavaScript or need a refresher, you can dive in or brush up at Mozilla Developer Network. To work with React Native, you will need to have an understanding of JavaScript fundamentals. Already familiar with React? You can skip that section-or read it for a light refresher. You can start here and read through these docs linearly like a book or you can read the specific sections you need. These docs were written for all learners, no matter their experience level or background. Many different kinds of people use React Native: from advanced iOS developers to React beginners, to people getting started programming for the first time in their career. Continue reading for an introduction to the documentation, Native Components, React, and more! Welcome to the very start of your React Native journey! If you're looking for environment setup instructions, they've moved to their own section.
