JosefAlbers/VimLM: VimLM is a Vim plugin that provides an LLM-powered assistant for code editing by allowing users to interact with a local LLM model through Vim commands and automatically ingesting code context.

LLM-powered coding companion for Vim, inspired by GitHub Copilot/Cursor. Integrates contextual code understanding, summarization, and AI assistance directly into your Vim workflow.

• Model Agnostic – Use any MLX-compatible model via a configuration file
• Vim-Native UX – Intuitive keybindings and split-window responses
• Deep Context – Understands code context from:
  • Current file
  • Visual selections
  • Referenced files
  • Project directory structure
• Conversational Coding – Iterative refinement with follow-up queries
• Air-Gapped Security – 100% offline – no APIs, no tracking, no data leaks

• Apple M-series chip
• Python 3.12.8

• Ctrl-l: Add current line + file to context
  Example prompt: "Regex for removing HTML tags from item.content"

• Select code → Ctrl-l: Add selected block + current file to context
  Example prompt: "Convert this to async/await syntax"

• Ctrl-j: Continue current thread
  Example follow-up: "Use Manifest V3 instead"

• Ctrl-p: Insert code blocks from response into:
  • Last visual selection (Normal mode)
  • Active selection (Visual mode)

Workflow Example:

1. Select a block of code in Visual mode
2. Prompt with Ctrl-l: "Convert this to async/await syntax"
3. Press Ctrl-p to replace selection with generated code

!include [PATH]  # Add files/folders to context

• !include (no path): Current folder
• !include ~/projects/utils.py: Specific file
• !include ~/docs/api-specs/: Entire folder
  Example: "AJAX-ify this app !include ~/scrap/hypermedia-applications.summ.md"

!deploy [DEST_DIR]  # Extract code blocks to directory

• !deploy (no path): Current directory
• !deploy ./src: Specific directory
  Example: "Create REST API endpoint !deploy ./api"

!continue [MAX_TOKENS]  # Continue stopped response

• !continue: Default 2000 tokens
• !continue 3000: Custom token limit
  Example: "tl;dr !include large-file.txt !continue 5000"

!followup  # Equivalent to Ctrl-j

Example:
Initial: "Create Chrome extension"
Follow-up: "Add dark mode support !followup"

Chain multiple commands in one prompt:

"Create HTMX component !include ~/lib/styles.css !deploy ./components !continue 4000"

VimLM uses a JSON config file with the following configurable parameters:

{
  "DEBUG": true,
  "LLM_MODEL": null,
  "NUM_TOKEN": 2000,
  "SEP_CMD": "!",
  "USE_LEADER": false
}

1. Browse models: MLX Community Models on Hugging Face
2. Edit config file:

{
  "LLM_MODEL": "mlx-community/DeepSeek-R1-Distill-Qwen-7B-4bit",
  "NUM_TOKEN": 9999
}

3. Save to: ~/vimlm/config.json
4. Restart VimLM
