redox-core

Core editor library for Redox.

redox-core contains the editor primitives and behaviour that should stay independent of any UI. Frontends should depend on this crate for buffer/session logic and keep rendering, input mapping, and terminal/platform concerns outside it.

What lives here

• Rope-backed text buffers via ropey
• Positions, selections, line/column indexing, and text slicing helpers
• Small composable edit operations and edit summaries
• Vim-style motions and text objects
• Search helpers and delimiter matching
• Fuzzy matching and path-ranking helpers used by the file finder
• Multi-buffer session management, including dirty tracking and background loading
• File I/O helpers for loading and saving buffers
