BadgeSort

Generate and Sort Branded Shields.io and Badgen.net Badges by Color

This is a Python 3 command-line tool and GitHub Action automating the generation and color sorting of badges from Shields.io and Badgen.net that contain brand logos from Simple Icons.

🎨 Interactive Generator

New! Try the interactive web-based generator to visually configure and generate your BadgeSort YAML! No installation required - just select your badges, configure the options, and copy the generated GitHub Actions YAML.

Background:

Many awesome GitHub profiles contain a series of these badges to clearly indicate which tools, services, or other brands the user is affiliated with. These badge collections usually adopt the brand's color, icon, and name.

The problem:

Badge services like Shields.io and Badgen.net provide URLs for these badges that are normally handcrafted or copypasta.

For Shields.io, the format is: https://img.shields.io/badge/<URL_ENCODED_BRAND_NAME>-<BRAND_HEX_COLOR>.svg?style=<BADGE_STYLE>&logoColor=<TEXT_HEX_COLOR>&logo=<SIMPLE_ICONS_SLUG>

For Badgen.net, custom icons require base64-encoded SVG data: https://badgen.net/badge/icon/<BRAND_NAME>?icon=<BASE64_ENCODED_SVG>&label&color=<BRAND_HEX_COLOR>

Normally, the user must repeat the process of manually rendering this URL for each badge they wish to display. This is what the result of this work might look like:

Unsorted Badges

Then, if the user is inclined, they may spend additional time ordering the badges by color to make their profile more visually appealing:

Sorted Badges

This is a time consuming process if performed manually; it is difficult to maintain, hard to keep consistent, and makes future adjustments offputting.

The solution:

This project automates the process of rendering out the badges into Markdown or HTML from a simple list of slugs.

The badges can be sorted by color [as default] or left in the order specified.

1D Hilbert sorted colors

Note Thanks to this article by Alan Zucconi, the visually appealing color sort is achived using a Hilbert walk.

Setup Requirements:

Comment Markers for Badge Interpolation

When using BadgeSort to update a file (like README.md), you must include special HTML comment markers in your target file. These markers tell BadgeSort where to insert or update the badges.

Required Syntax:

<!-- start chipwolf/badgesort {id} -->
<!-- end chipwolf/badgesort {id} -->
  • {id}: A unique identifier that matches the id parameter in your GitHub Action or CLI command
  • BadgeSort will replace everything between these markers with the generated badges
  • The markers themselves are preserved and remain in your file

Default ID:

If you don't specify an id, the default value is default:

<!-- start chipwolf/badgesort default -->
[![BadgeSort](https://img.shields.io/badge/BadgeSort-000000.svg?style=for-the-badge&logo=githubsponsors)](https://github.com/ChipWolf/BadgeSort)
![GitHub](https://img.shields.io/badge/GitHub-181717.svg?style=for-the-badge&logo=github&logoColor=white)
![Node-RED](https://img.shields.io/badge/Node--RED-8F0000.svg?style=for-the-badge&logo=nodered&logoColor=white)
![osu!](https://img.shields.io/badge/osu%21-FF66AA.svg?style=for-the-badge&logo=osu&logoColor=white)
![OpenSea](https://img.shields.io/badge/OpenSea-2081E2.svg?style=for-the-badge&logo=opensea&logoColor=white)
![American Express](https://img.shields.io/badge/American%20Express-2E77BC.svg?style=for-the-badge&logo=americanexpress&logoColor=white)
<!-- end chipwolf/badgesort default -->

Multiple Badge Sections:

You can have multiple badge sections in the same file by using different IDs:

<!-- start chipwolf/badgesort section1 -->
<!-- end chipwolf/badgesort section1 -->

Some other content...

<!-- start chipwolf/badgesort section2 -->
<!-- end chipwolf/badgesort section2 -->

Important Without these comment markers in your target file, BadgeSort will only output badges to stdout (or the console) rather than updating the file.

Examples:

Generate five specific badges ordered by color:

GitHub Action:

      - uses: docker://ghcr.io/chipwolf/badgesort:latest
        with:
          format: markdown # default
          id: default # default
          output: README.md
          slugs: |
            osu
            github
            americanexpress
            nodered
            opensea
          sort: hilbert # default
          style: for-the-badge # default

CLI:

$ python -m badgesort.icons -s osu github americanexpress nodered opensea -o README.md

Required comment markers in README.md:

<!-- start chipwolf/badgesort default -->
[![BadgeSort](https://img.shields.io/badge/BadgeSort-000000.svg?style=for-the-badge&logo=githubsponsors)](https://github.com/ChipWolf/BadgeSort)
![GitHub](https://img.shields.io/badge/GitHub-181717.svg?style=for-the-badge&logo=github&logoColor=white)
![Node-RED](https://img.shields.io/badge/Node--RED-8F0000.svg?style=for-the-badge&logo=nodered&logoColor=white)
![osu!](https://img.shields.io/badge/osu%21-FF66AA.svg?style=for-the-badge&logo=osu&logoColor=white)
![OpenSea](https://img.shields.io/badge/OpenSea-2081E2.svg?style=for-the-badge&logo=opensea&logoColor=white)
![American Express](https://img.shields.io/badge/American%20Express-2E77BC.svg?style=for-the-badge&logo=americanexpress&logoColor=white)
<!-- end chipwolf/badgesort default -->

Note: The id value default in the comment markers matches the id parameter in the GitHub Action (or the default when not specified in CLI).

Output:

BadgeSort GitHub Node-RED osu! OpenSea American Express


Generate five random badges:

GitHub Action:

      - uses: docker://ghcr.io/chipwolf/badgesort:latest
        with:
          id: foobar
          format: html
          output: README.md
          random: 5
          sort: false
          style: flat-square

CLI:

$ python -m badgesort.icons -i foobar -c false -r 5 -f html -b flat-square -o README.md

Required comment markers in README.md:

<!-- start chipwolf/badgesort foobar -->
<p>
  <a href="#"><img alt="Aeroflot" src="https://img.shields.io/badge/Aeroflot-02458D.svg?style=flat-square&logo=aeroflot&logoColor=white"></a>
  <a href="#"><img alt="Dropbox" src="https://img.shields.io/badge/Dropbox-0061FF.svg?style=flat-square&logo=dropbox&logoColor=white"></a>
  <a href="#"><img alt="OpenCV" src="https://img.shields.io/badge/OpenCV-5C3EE8.svg?style=flat-square&logo=opencv&logoColor=white"></a>
  <a href="#"><img alt="OpenGL" src="https://img.shields.io/badge/OpenGL-5586A4.svg?style=flat-square&logo=opengl&logoColor=white"></a>
  <a href="#"><img alt="MSI" src="https://img.shields.io/badge/MSI-FF0000.svg?style=flat-square&logo=msi&logoColor=white"></a>
  <a href="https://github.com/ChipWolf/BadgeSort"><img alt="BadgeSort" src="https://img.shields.io/badge/BadgeSort-000000.svg?style=flat-square&logo=githubsponsors"></a>
</p>
<!-- end chipwolf/badgesort foobar -->

Note: The custom id value foobar must match in both the GitHub Action input (or CLI -i parameter) and the comment markers.

Output:

Aeroflot Dropbox OpenCV OpenGL MSI BadgeSort


Generate badges from a list of slugs, sorting using an inverted step algorithm:

GitHub Action:

      - uses: docker://ghcr.io/chipwolf/badgesort:latest
        with:
          args: |
            --hue-rotate 240
          id: example
          format: html
          output: README.md
          sort: step_invert
          style: flat
          slugs: |
            angular,apollographql,brave,d3dotjs,docker
            git,githubactions,googlecloud,graphql,heroku
            html5,insomnia,mongodb,nestjs,nodedotjs
            npm,prettier,react,reactivex,redux
            rollupdotjs,sass,styledcomponents,typescript,webpack

CLI:

$ python -m badgesort.icons -i example -c step_invert -o README.md -f html -b flat --hue-rotate 240 -s \

Generate badges with Badgen.net:

GitHub Action:

      - uses: docker://ghcr.io/chipwolf/badgesort:latest
        with:
          id: badgen-example
          format: markdown
          output: README.md
          provider: badgen
          slugs: |
            github
            python
            docker
            oxygen
          sort: hilbert

CLI:

$ python -m badgesort.icons -p badgen -s github python docker oxygen

Note on Badgen Icon Visibility

Unlike Shields.io, Badgen.net doesn't support black text on badges, only white text on colored backgrounds. To ensure icon visibility on bright brand colors, BadgeSort automatically adjusts very bright icons:

  • Bright icons (brightness > 0.7): Scaled down to brightness of 0.7 for optimal visibility

This preserves the icon's hue and saturation while ensuring it remains visible against bright brand color backgrounds.

Output:
