Zeta Tab Completion Steel Plugin for Helix

Note: This plugin was vibecoded fully with Opus 4.6 since I am not well versed with the scheme language or had the time. as of uploading this I have not yet read the code, however the plugin works, it currently runs on LM-Studio with the Zeta-2 GGUF quantization by NexVeridian.

Installation

Simply add ./zeta-complete.scm to your $XDG_CONFIG_DIR/helix and then include this in your init.scm:

(require "zeta-complete.scm")
(add-global-keybinding
 (hash "insert" (hash "tab" ':zeta-accept
                      "C-]" ':zeta-dismiss)
       "normal" (hash "space" (hash "z" ':zeta-toggle))))

Keybinds

As the keybinds are set above the default is:

Key	Action
Tab	Accept Completion
C-]	Dismiss Completion
Space z	Toggle Zeta Completions

Requirements

• Helix Editor built from source from the Scheme PR
• LM-Studio (though any OpenAI Compatible host for the model should work if you change a few lines)
  • Zeta-2 Model by Zed-Industries
  • ~6GB of Ram/VRam (though the model is quantized and should run on any modern GPU, CPU might be far too slow)
