Part I – Architecture OverviewPart II – Breaking Down the EditorPart III – State ManagementPart IV – Distributed TransactionsPart V – The Story of Code Completion In Parts III and IV of this series, we discussed the complicated abstract architectural concepts involved in state management and how they are synchronized across Fleet’s distributed components. Now it’s time for us to look at a more familiar function – Code completion – and see how it is implemented in Fleet. Fleet is not a tremendous breakthr

This is a multipart series on building Fleet, a next-generation IDE by JetBrains. Part I – Architecture OverviewPart II – Breaking Down the EditorPart III – State ManagementPart IV – Distributed Transactions In Part III of this series, we focused on how we represent, store, and change elements of Fleet’s state. In this part, we’ll talk about Fleet as a distributed IDE and how it guarantees the consistency of data across all of its distributed components. Fleet is a platform for real-time remote collaboration between developers. This is an exciting area of technology! Let’s start by di

This is a multipart series on building Fleet, a next-generation IDE by JetBrains. Part I – Architecture OverviewPart II – Breaking Down the EditorPart III – State Management In previous parts of this series, we looked at an overview of the Fleet architecture and discussed the algorithms and data structures that are used under the hood in the editor. In this part, we’ll start looking at the approach we take to implement state management. This is a complicated topic, so we’ll devote a couple of blog posts to it. For now, we’ll focus on how we represent and store elements of the application

This is a multipart series on building Fleet, a next generation IDE by JetBrains. Part I - Architecture OverviewPart II - Breaking down the editor In the first part of this series we looked at an overview of the Fleet architecture. In this second part we’re going to cover the algorithms and data structures that are used under the covers in the editor. An aggregate of data structures Take a look at the following screenshot of the editor window in Fleet There’s a line of text with syntax highlighting and a widget providing information about usages of the particular variable.

This is a multipart series on building Fleet, a next generation IDE by JetBrains. Part I - Architecture OverviewPart II - Breaking down the editor We recently announced a new product which we have been working on named Fleet, a new generation IDE by JetBrains. The product is currently in closed preview and we’re receiving great feedback from early adopters, helping us improve it and get it ready for a public preview sometime in 2022. In the meantime, and until we’re ready for public access, we’d like to talk to you a bit about how Fleet is built under the covers. In a series of bl

Update (Dec 3, 2021): We’ve received an overwhelming number of requests for the Fleet Early Preview program. Unfortunately we can't accept any new requests, but we will continue sending invites to those who have already signed up. You're welcome to subscribe for updates and the public preview announcement at jetbrains.com/fleet or follow @JetBrains_Fleet on Twitter. For years folks have been asking us, "JetBrains, when will you create a lightweight editor?" Well, today we're extremely happy to announce Fleet, a lightweight editor but with a twist! When you first launch Fleet, it s
