Hi, I'm patchwright

I find small, real, provable bugs in open-source Python and fix them. Every fix ships with a regression test that fails on the old code, so the bug proves itself.

Tooling

🔧 wildlint · pip install wildlint Static checks distilled from real upstream bugs that off-the-shelf linters miss. Each rule comes from an actual bug I found and fixed upstream — see the merges below.

Merged upstream

• nephila/giturlparse #152 — path/branch parsing stripped every /blob/·/tree/ marker instead of just the leading one. (merged 2026-06-16)
• mahmoud/boltons #403 — bytes2human didn't roll over at exact powers of 1024 (1024 → '1024B' instead of '1K'); off-by-one <= boundary. (merged 2026-06-17)
• skorokithakis/shortuuid #115 — string_to_int ignored its documented alphabet_index, using the wrong radix. (merged 2026-06-18)
• go-openapi/strfmt #269 — JSON-Schema "uri" validation wrongly rejected absolute URIs containing a #fragment (RFC 3986). (Go; merged 2026-06-22)
• derek73/python-nameparser #164 — split(' ') vs split() left a stray leading space and [''] instead of [] in capitalized surnames. (merged 2026-06-27)

Open / in review

• jkwill87/mnamer #371 — str_title_case used break where it needed continue, so later exception words stayed capitalized.
• python-validators/validators #463 — cron() rejected valid comma-separated ranges due to branch ordering.
• savoirfairelinux/num2words #661 — Mongolian ordinal IndexError on zero (unguarded [-2] index).
