Not sure how to say this without sounding like a bit of an asshole, but why should we care? What does Theia do better than VS Code? For some relevant context I don’t consider VS Code to be a good IDE, but it’s not a bad editor. I use it when I need to crack open some random file (typically markdown or JSON) with maybe a bit of syntax highlighting, but I would never use it for programming.
Article was a bit light on who the intended audience is for Theia. VS Code’s big selling points are that it’s super fast to open and has a robust extension ecosystem, is Theia going to provide the same, and how are they planning to convince current VS Code users to switch?
Most of the tools that make an IDE an IDE. Refactoring abilities are very limited and basic. Quickly navigating complex code bases becomes tricky. The code completion and type annotations are often missing or just plain wrong. When compared to something like essentially any IDE offered by JetBrains it just doesn’t stack up. Prior to RustRover being released I briefly tried to use VS Code for Rust using its LSP plugin, but it was just really bad in general, it utterly failed to analyze the code and provided almost no contextual help.
