Single-File VSCode Extension

Transform your codebase into LLM-friendly formats directly from Visual Studio Code. This extension leverages Single-File CLI under the hood to create optimized, context-aware representations of your code that are perfect for AI analysis and prompting. This extension provides a user-friendly interface to configure paths, arguments, metadata options, pyenv versions, and more—right inside VS Code.

LLM Tuned - Smart Context Preservation

  • Automatically maintains crucial relationships between files and dependencies.
  • Preserves import hierarchies and module structures.
  • Includes relevant metadata and hints that help LLMs understand your code better.

Features

  • Global Defaults: Configure your Single-File path, optional Pyenv version, and any additional config root paths.
  • Run Dialog: Right-click folders/files (or use the command palette) to open a Run panel where you can:
    • Adjust arguments like paths, output, formats, configs and more.
    • Quickly Export these arguments as a reusable JSON config.
  • Sticky Workspace Settings: The last used arguments are saved per-project so you don’t have to re-enter them.
  • Auto-Configuration Prompt: If you haven’t set up Single-File yet, the extension will prompt you to configure it globally on first use.
  • Run “Last Settings”: Quickly re-run Single-File with your most recent arguments—no dialog required.

Requirements

  1. Python 3.x
  2. The Single-File CLI installed (or placed in your configured singleFileRoot).
  3. (Optional) pyenv if you wish to specify a particular Python version inside VS Code.
  4. (Coming Soon) venv if you wish to specify a particular Python virtual environment.

Limitations

  1. [FIXED] Cursor.ai Context menus are not working. So use [CTRL+SHFT + P] to launch.

Installation

  1. Install or Enable the extension (from the VS Code Marketplace or by manual .vsix file).
  2. Ensure that you have the Single-File CLI on your system or configured in the extension’s single-file (singleFileRoot).

Configure Global Defaults (Optional)

If you want a custom Single-File root or a specific Python version (via pyenv):

  1. Press Ctrl+Shift+P (or Cmd+Shift+P on macOS) to open the command palette.
  2. Type Single-File: Configure Single-File Global Defaults.
  3. Set your singleFileRoot, pyenvVersion, and any additional config root paths.
  4. Click Save Defaults.

Usage

1. Right-Click Menu

  • Right-click on any file(s) or folder(s) in the Explorer panel.
  • Choose Single-File → Run to open a dialog:
    • Configure arguments, such as paths, output format(s), metadata, etc.
    • Run or Save As Config to store your chosen parameters in a JSON config file.
  • Use Single-File → Run (Last Settings) to re-run with no additional prompts.

2. Command Palette

  • Press Ctrl+Shift+P (or Cmd+Shift+P) and type:
    • Single-File: Run → Opens the argument dialog.
    • Single-File: Run (Last Settings) → Skips the dialog; uses your saved arguments.
    • Single-File: Configure Single-File Global Defaults → Adjust the global extension settings.

Troubleshooting

  • Global Defaults Not Set: If you haven’t configured singleFileRoot, the extension will prompt you on first use. Make sure Single-File is installed or accessible at the path you configure. You should set your singleFileRoot to the repo directory on your local system.
    • Example: '/home/< username >/dev/single-file'
  • Check Output Logs: Go to View → Output in VS Code, then select Single-File in the dropdown. This log may show errors about missing paths, invalid arguments, or Python environment issues.
  • Pyenv: If you specify a pyenvVersion, ensure that version is installed via pyenv (and accessible on your system).

More on Single-File

The Single-File CLI is a Python-based tool that flattens codebases, gathering metadata such as file size, checksums, or custom plugin data. It supports multiple output formats—text, markdown, json, etc.—and can merge arguments from both CLI flags and JSON config files.

To dive deeper:

  • GitHub: chrisdreid/single-file
  • For environment variables, advanced config, plugin architecture, or code-based usage, see the CLI repository’s documentation.
