Flow Control: a progammer's text editor

a programmer’s text editor

Flow Control is under active development, but very stable.

🚀 Features

• Lightning Fast TUI with ≤6ms frame times, low latency input handling and smooth animated scrolling
• Intuitive UI with tabs, scrollbars and palettes with full mouse support for all UI elements
• Support for more than 70 programming languages, zero configuration needed, via tree-sitter powered syntax highlighting
• Language Server Protocol pre configured support for most language servers
• Powerful multi-cursor editing and integrated clipboard history
• Powerful configurable keybinding system that supports modal and non-modal editing styles
• Multiple pre-configured keybinding modes
  • Flow Control - GUI IDE style bindings (similar to vscode)
  • Emacs
  • Vim
  • Helix
  • User created
• Hybrid rope/piece-table buffer system, edit very large files with thousands of cursors
• Infinite undo (at least until you run out of ram)
• Full unicode support, including support for the kitty text sizing protocol
• Plenty of themes included and support for vscode themes via the flow-themes project
• Runs on Linux, FreeBSD, MacOS, Windows and Android (under termux) with easy cross-compilation to all supported targets

Requirements

• A modern terminal with 24bit color and, ideally, kitty keyboard protocol support. Kitty, Foot and Ghostty are the recommended terminals at this time. Zellij also works well. Most other terminals will work, but likely with reduced functionality.
• NerdFont support. Either via terminal font fallback or a patched font.
• A UTF-8 locale
