# Display Repo Size for GitHub (OpenScript Userscript)
A lightweight OpenScript userscript that displays the total repository size directly in the **About** section on GitHub repository pages (for both public and private repositories).
A lightweight OpenScript userscript that displays the total repository size (including all commit history, branches, tags, and packfiles) directly in the **About** section on GitHub repository pages (for both public and private repositories).
## Features
- **Integrated in About Section**: Injects cleanly under repository details in the right sidebar (e.g. `📦 673.9 KB repo size`).
- **Accurate Size Detection**: Automatically detects when GitHub's API returns `0 KB` on newly created repositories and falls back to calculating the total content size via the Git Trees API.
- **Private & Public Repositories**: Works on public repositories out-of-the-box and uses `GH_PAT` from OpenScript secrets for private repositories.
- **Accurate Git History Size**: Uses GitHub's native `repo.size` disk usage measurement, accurately reflecting the full Git history, delta compression, and packfiles rather than loose blobs.
- **New Repo Handling**: If a repository was just pushed and GitHub is still computing initial disk usage (`0 KB`), it provides a friendly indicator (`0 KB (calculating...)`) until GitHub finishes indexing.
- **Integrated in About Section**: Injects cleanly under repository details in the right sidebar.
- **Private Repositories Supported**: Uses `GH_PAT` from OpenScript secrets for private repositories and increased rate limits.
- **Turbo / SPA Compatible**: Seamlessly persists across GitHub's Turbo and client-side page transitions.
