chromium-search-migrator 0.1.0

Migrate Chromium search engines between Web Data databases.

chromium-search-migrator

Migrate active Chromium search engines from one Web Data database into another.

This is useful for moving custom search engines from Arc Browser to Google Chrome.

Usage

Dry run:

uv run chromium-search-migrator \
  "$HOME/Library/Application Support/Arc/User Data/Default/Web Data" \
  "$HOME/Library/Application Support/Google/Chrome/Default/Web Data"

Apply changes:

uv run chromium-search-migrator \
  "$HOME/Library/Application Support/Arc/User Data/Default/Web Data" \
  "$HOME/Library/Application Support/Google/Chrome/Default/Web Data" \
  --apply

List entries that would be imported:

uv run chromium-search-migrator source-web-data target-web-data --list

Safety

• Only imports source rows with is_active = 1.
• Skips rows when the target already has the same keyword.
• Skips rows when the target already has the same url.
• Regenerates sync_guid for imported rows.
• Creates a backup in /tmp before writing, unless --no-backup is set.
• Runs PRAGMA integrity_check after writing.

Close the target browser before applying changes, otherwise the database may be locked.
