Aichan Mail Signature

My email signature in two variants: hot-linked images and embedded (base64) images

Image URLs

Links for images are served from Forgejo raw URLs:

https://git.prisma.moe/aichan/aichan_mail_signature/raw/branch/main/images/{filename}

Automatic Base64 Generation

The Forgejo Actions workflow (.forgejo/workflows/generate-signature.yml) automatically:

1. Triggers on:

   • Push to main/master branch
   • Changes to images/ or signature_template.html
   • Manual trigger via Forgejo UI

2. Process:

   • Reads signature_template.html
   • Converts all images in images/ to base64
   • Minifies output (removes whitespace between tags)
   • Generates signature_base64_generated.html
   • Auto-commits and pushes (with [skip ci] to prevent loops)

Usage

Option A: Hot-Linked Signature

1. Push to Forgejo:

   git add .
   git commit -m "Update signature"
   git push
   

2. Copy to Mail:

   • Open signature.html in browser
   • Select all (Ctrl+A), Copy (Ctrl+C)
   • Paste into the mail signature editor

Pros: Lightweight, easy to update Cons: Requires external image loading

Base64 Signature (Maximum Compatibility)

1. Wait for CI/CD to generate signature_base64_generated.html

2. Copy to Mail:

   • Open signature_base64_generated.html in browser
   • Select all, copy, paste

Pros: Works offline, no external dependencies Cons: Larger file size (144K)

Updating Images

Just replace files in images/ folder and push:

cp ~/new_logo.png images/aichan.moe.png
git add images/aichan.moe.png
git commit -m "Update aichan.moe logo"
git push

Hot-linked signature: Updates immediately Base64 signature: Auto-regenerated by CI/CD in ~1 minute
