ChimeKit provides the functionality needed to build extensions for Chime, the editor for macOS. You can use it to provide semantic features, display views, and integrate with ExtensionKit. Chime can do a lot more with extensions.
Chime's extensions are based on ExtensionKit. They are written in Swift and SwiftUI. ChimeKit also includes a system for integrating Language Server Protocol servers with the extension API. For the most part, ChimeKit abstracts away all of the ExtensionKit details. You program against the ChimeKit APIs, not the ExtensionKit primitives. However, ExtensionKit does impose some requirements related to security and distribution you must be aware of.
ChimeKit development requires Chime 2.0, Xcode 14, and macOS Ventura (13.0).
Chime Extension Gallery
This is a first-party extension hosting application, signed by our Developer ID. It will handle discovery and updates, and all open source extensions will be eligible to apply for inclusion. This app will be open source, but it is forthcoming. The actual details of how your sources will be integrated isn't worked out yet, so if you have thoughts, get in touch.
We want to provide a simple user experience for extensions, particularly for language support. We don't think it's great to have four different extensions for one language. So, while we will not gatekeep, we'll have a very strong bias towards one extension per language.
LSP is pervasive in language support extensions. Many IDEs use a model of one extension per language server. ChimeKit allows for multiple servers per extension. We think of LSP servers as an implementation detail of language support. Coordinating the behaviors of multiple servers is the job of an extension, not the user.
Chime's core Go and Ruby support aren't open source, yet. But, we will be publishing them. And, going forward, we will always begin work on new language support as open source projects.
ChimeKit supports two different integration options, both available via SPM. Read more in the documentation.
