The implementation of the extension boils down to how to glue the two awesome tools mentioned above together and, in all honesty, I tried to keep everything as simple as possible in order to have a proof of concept up and running quickly. It is configured with the tabs layout and it gets passed the user’s VS Code theme background color so it integrates better with the editor. ROOT File Viewer makes use of the HierarchyPainter object to do all the heavy lifting regarding the handling of the ROOT files and the drawing of the objects stored in it. It is basically a drawing and I/O library that can be used to provide interactive plots and many other ROOT core functionalities, as can be seen on the examples page. JavaScript ROOT brings ROOT to the browser. We could go deep into details here, but that is probably outside of the scope of this post. The view of the file is implemented through the Webview API, and the document model is a custom RootFileDocument class which we will keep simple by implementing a CustomReadonlyEditorProvider, the RootFileEditorProvider. The custom editor requires two parts: a view and a document model. In the case of the ROOT File Viewer extension, the Custom Editor API is leveraged to handle ROOT Files. Moreover, its functionality can easily be extended thanks to the Extension API. It runs on any operating system, supports many languages, has built-in support for Git, and much more. VS Code is a free, open source, and very popular code editor developed by Microsoft with TypeScript, a superset of JavaScript. or running code -install-extension albertopdrf.root-file-viewer from the command lineĪnd if you want to know more, just keep reading!

And I haven’t even mentioned yet that for this extension to work no local installation of ROOT is required! The good news is that that isn’t the case any longer! Let me present ROOT File Viewer, an extension for Visual Studio Code that makes use of the wonderful JavaScript ROOT to display ROOT Files directly within VS Code, with just a click!īefore diving into the details, let us just quickly see the extension in action. Configure the module-alias, adding these lines in your package.View ROOT Files directly in VS Code! (11 March 2021)Īs a heavy user of ROOT, many of the results of my data analysis are saved in ROOT Files and, honestly, I always found it a bit annoying to glance over them.Install the module-alias module (as a dependency of the project): npm install module-alias -save.

Configuring JavaScriptĪs I was saying in the introduction, if you now take a look into one of your JavaScript file in the distribution directory, you’ll notice that the are still all there. Remember also to restart Visual Studio Code once you’ve finished with your tsconfig.json, or the Intellisence won’t find the modules. Now you can rename your module paths in your imports using those aliases, run your build script and TypeScript won’t even blink.

you can even alias one single file, and not a directory (like I do in the api example).

you can only use one asterisk in the paths (nothing like the somedir/**/* we sometimes use somewhere else).

the baseUrl is relative to the directory where your tsconfig.json resides.

The moduleResolution defaults to classic but nowadays we can safely use node.

Open your tsconfig.json and add something like the following snippet to your compilerOptions object (this is obviously just a part of my own configuration, so YMMV): 'moduleResolution': 'node', 'baseUrl': 'src', 'paths':

😐 Typescript does not emit the resolved aliased path to JavaScript, which means that without some help, your JavaScript application won’t be able to understand what that things is.

🙂 Visual Studio Code Intellisense for TypeScript supports this feature (it reads the tsconfig.json, but you need to restart it –or reload your window– whenever you change that file).

😃 TypeScript natively supports this feature and you just need to set it up in your tsconfig.json.
