Sync Dotfiles

Sync Dotfiles

Sync dotfiles from the private chezmoi repository (~/.local/share/chezmoi) to the public dotfiles repository (~/Developer/misc/dot). This skill processes chezmoi templates and applies safety filtering to prevent accidentally syncing sensitive data.

Workflow

1. Run the sync script

Execute the sync script to copy files from chezmoi to the public repo:

python scripts/sync_dotfiles.py

The script will:

• Get all files managed by chezmoi
• Filter out sensitive patterns (.ssh/, .gnupg/, *secret*, *token*, *password*, etc.)
• Render chezmoi templates to get final file content
• Copy rendered files to the public repo
• Leave all changes unstaged for manual review

Options:

• --dry-run: Preview what would be synced without copying files
• --chezmoi-dir <path>: Override chezmoi source directory (default: ~/.local/share/chezmoi)
• --public-repo <path>: Override public repo directory (default: ~/Developer/misc/dot)

Example with dry run:

python scripts/sync_dotfiles.py --dry-run

2. Review changes

After syncing, review the unstaged changes in the public repo:

cd ~/Developer/misc/dot
git status
git diff

Check carefully for:

• Sensitive information (API keys, tokens, passwords)
• Private paths or system details
• Anything you're not ready to share publicly

3. Selectively stage changes

Stage only the files you want to make public:

# Stage specific files
git add .zshrc .vimrc

# Or stage all changes if everything looks good
git add -A

# Or discard changes you don't want
git restore <file>

4. Commit and push when ready

git commit -m "Update dotfiles"
git push

Safety Blocklist

The script automatically skips these sensitive patterns:

• SSH/GPG: .ssh/*, .gnupg/*, *.pem, *.key, *_rsa, *_ed25519
• Credentials: *secret*, *password*, *token*, *credential*, *.env, *api_key*
• Cloud: .aws/credentials, .aws/config, .azure/*, .gcloud/*
• Other: .netrc, .docker/config.json, *_history, shell histories

These patterns provide a safety net, but always manually review the diff before committing.

Template Processing

The skill uses chezmoi cat to render templates, which means:

• Template variables are resolved to their actual values
• Conditional sections are processed
• The public repo gets the final rendered output, not the .tmpl files

This ensures your public dotfiles show what users would actually use, not chezmoi's internal template syntax.
