What Hacker News says
4 sourcesI have just released version 1.1.0 which should fix the problems reported by users.

In Show HN: K(r)ep - A high-performance string search utilityThank you for the report! Here’s what I changed:
1. Always use the raw bad_char_table[text[i + pattern_len‑1]] shift—no extra lowercase lookup at runtime.
2. After a full match, advance by that same table shift instead of just doing i++, so you never miss overlapping occurrences.
3. Removed the “if shift==0 then shift=1” guard—since we build the table excluding the last pattern byte, zero shifts can’t occur.
