Ferrite is a fast and lightweight text editor designed for Markdown, JSON, YAML, and TOML files, built with Rust and egui. It operates primarily on Windows and Linux, with macOS support still in experimental stages. The latest version, v0.2.6.1, marks the first code-signed release, which enhances security by reducing antivirus false positives and enables users to verify the integrity of the application. Users who experience quarantine issues with Windows Defender are advised to download the latest version, check the digital signature, or use VirusTotal for verification. The editor supports multiple file formats and encodings, offers features like WYSIWYG Markdown editing, multi-cursor editing, and integrated terminal functionality. It includes a split view for side-by-side editing and previewing, a semantic minimap for navigation, and various editing tools such as regex-based find and replace, code folding, and auto-save options. Users can customize their experience with configurable fonts and keyboard shortcuts. Ferrite also includes AI-generated code, which was developed transparently, allowing others to learn from the process. Recent updates introduced significant features like a custom editor engine for improved performance, native rendering of diagrams using Mermaid, and enhanced Git integration to visualize file status. The workspace mode facilitates easy navigation through folders, while the integrated terminal supports multiple shell types. Overall, Ferrite combines a range of productivity features with a focus on performance and user experience, making it a compelling choice for developers and writers working with structured text files.
