xdv-edx

Version: 0.2.x
Status: Active
Language: Dust Programming Language (DPL)

xdv-edx is the terminal editor subsystem for XDV OS.

Current Scope

Current source provides:

• deterministic input classification (control, motion, edit, printable)
• deterministic command/keypath dispatch (run_key_command, run_command)
• deterministic buffer model (clean/dirty) with explicit transition helpers
• render path aligned to buffer line model and cursor positioning
• xdvfs path-contract validation for file open/save
• editor lifecycle (main -> boot -> init -> launch -> run)

xdvfs Path Contract

edx_file enforces xdvfs-oriented path normalization and contract checks before open/save. Default path resolution uses the editor default path profile in the /console contract space.

• edx_buffer_tests.ds
• edx_input_tests.ds
