Changelog

v0.3.0

pattex v0.3.0 brings a significant internal restructuring alongside new features and bug fixes.

---

Breaking / Structural

• internet.py has been split into email_extractor.py and url_extractor.py. If you were importing directly from the internal module path, update your imports. Top-level pattex imports are unaffected.

New Features

• URL Extraction — extract_urls(text, mode), extract_urls_by_scheme(text, scheme), and extract_urls_by_domain(text, domain) are now available. Supports strict and permissive modes covering HTTP/S, FTP, WebSocket, IPv4, IPv6, bare domains, and localhost.
• Gmail normalisation — extract_gmail_emails now accepts normalize=True which strips dots from the local part, unifies @googlemail.com to @gmail.com, and deduplicates canonical variants.
• is_valid_provider_email(email, provider) — single function to validate whether an email belongs to a given provider (gmail, yahoo, outlook, icloud, zoho, proton).

Bug Fixes

• Fixed extract_emails_by_provider which was not dispatching to provider helper functions correctly — all six providers now route properly.

Status

Currently under active development. Full documentation and usage examples coming soon.
