# ghstats

> Generate SVG cards summarizing a GitHub user's profile — written in Go.

`ghstats` is a single-binary CLI (and a GitHub Action wrapping it) that fetches
public data for a GitHub user and writes a themed set of SVGs you can embed in
your profile README:

- Profile details
- Repos per language (how many owned repos use each language as primary)
- Most commit language (last year's commits attributed to each repo's primary language)
- Stats (stars, commits, PRs, issues, PR reviews, contributed-to)
- Productive time heatmap (weekday × hour)

## Use as a GitHub Action (recommended)

Drop this in `.github/workflows/ghstats.yml` in your **profile repo** (the one
named after your username):

```yaml
name: ghstats

on:
  schedule:
    - cron: "0 0 * * *" # daily
  workflow_dispatch:

permissions:
  contents: write

jobs:
  cards:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v5
      - uses: tiennm99/ghstats@v1
        with:
          user: ${{ github.repository_owner }}
          token: ${{ secrets.GHSTATS_TOKEN }}   # classic PAT with read:user + repo
          themes: dracula,github_dark,tokyonight
          tz: Asia/Saigon
          commit_changes: "true"
```

Then embed the cards in your `README.md`:

```md
![profile](./output/dracula/0-profile-details.svg)
![repos-per-language](./output/dracula/1-repos-per-language.svg)
![most-commit-language](./output/dracula/2-most-commit-language.svg)
![stats](./output/dracula/3-stats.svg)
![productive-time](./output/dracula/4-productive-time.svg)
```

## Themes

Run `ghstats -list-themes` for the full list (60+ themes ported from
github-profile-summary-cards). Built-ins include `default`, `dark`, `dracula`,
`github`, `github_dark`, `tokyonight`, `onedark`, `nord_dark`, `nord_bright`,
`gruvbox`, `radical`, `synthwave`, `monokai`, `solarized`, `solarized_dark`,
`transparent`, and more.

## Output

```
output/
  dracula/
    0-profile-details.svg
    1-repos-per-language.svg
    2-most-commit-language.svg
    3-stats.svg
    4-productive-time.svg
```

## Tokens & permissions

The default `${{ github.token }}` can read public user data but will not see
your private-repo commits. For accurate stats, create a **classic** personal
access token with `read:user` and `repo`, save it as a repo secret (e.g.
`GHSTATS_TOKEN`), and pass it via the `token` input.
