Text Editor

Mitos – modal terminal text editor based on Helix

Mitos is a modal text editor based on Helix. It retains Helix’s selection-first editing model while pursuing a different approach to editor development and introducing additional functionality.

The editor is designed for programmers who favour keyboard-driven editing. Instead of selecting an editing operation and then identifying the text to change, users typically select the text first and apply an operation afterwards. This approach makes it particularly convenient to manipulate multiple sections of code simultaneously.

Mitos combines a terminal interface with functionality commonly associated with graphical development environments. It integrates code intelligence, syntax-aware editing and debugging into a single application.

This is free and open source software.

Key Features

  • Selection-first modal editing model inherited from Helix.
  • Multiple selections and cursors for editing several locations simultaneously.
  • Built-in Language Server Protocol support for code completion, diagnostics and other language-aware functionality.
  • Debug Adapter Protocol integration for debugging supported programming languages.
  • Tree-sitter-powered incremental syntax highlighting and syntax-aware editing.
  • Terminal interface built using Ratatui.
  • Keyboard-driven navigation and editing commands.
  • Supports structural selections and transformations for manipulating source code.
  • Configurable editing behaviour and language-specific settings.
  • Provides contextual completion suggestions and documentation from supported language servers.
  • Supports code editing across multiple files and workspaces.
  • Cross-platform support – runs on Linux, macOS, and Windows.
