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.

🔧 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 PRs below.

• nephila/giturlparse #149 — path/branch parsing stripped every /blob/·/tree/ marker instead of just the leading one.
• jkwill87/mnamer #371 — str_title_case used break where it needed continue, so later exception words stayed capitalized.
• python-humanize/humanize #326 — fractional() doubled the minus sign on negative mixed numbers.
• python-validators/validators #463 — cron() rejected valid comma-separated ranges due to branch ordering.
• derek73/python-nameparser #164 — split(' ') vs split() left a stray space and [''] instead of [].
• savoirfairelinux/num2words #661 — Mongolian ordinal IndexError on zero (unguarded [-2] index).
• skorokithakis/shortuuid #115 — string_to_int ignored its documented alphabet_index, using the wrong radix.
• mahmoud/boltons #403 — bytes2human didn't roll over at exact powers of 1024 (1024 → '1024B' instead of '1K'); off-by-one <= boundary.
