Oni2
Oni2 is a high-performance, extensible text editor and project-based file manager. It functions as a modal code editor, utilizing a keyboard grammar of verbs and motions to navigate and modify source code without a mouse. It also serves as an LSP client, integrating Language Server Protocol servers to provide code completion, symbol navigation, and refactoring.
The editor distinguishes itself by acting as a VSCode extension host, allowing it to load and execute language servers and debuggers from the VSCode ecosystem. It provides a programmable environment where custom functionality is implemented via a dedicated host and communication protocol for third-party plugins.
The platform covers a broad range of development capabilities, including global project search with regular expression support, version control integration, and a system for managing multiple file buffers. It includes built-in language support, a project explorer for directory browsing, and a customizable interface with support for visual themes and per-filetype settings.
