Logs, errors, and diffs
Paste a log slice or a git diff when you need structure, not a SIEM. Log format and error-pattern tools look for timestamps, levels, and regex hits. Diff tools parse unified hunks — they do not apply patches to a repo on this server.
Git Diff Hunk Parser, Unified Diff Validator, and Git Apply Patch Checker overlap. Use one unified-diff page for syntax; treat the others as the same family until they are merged. ANSI cleaner strips escape codes so logs paste cleanly into tickets.
Log triage(3)
Log File AnalyzerAnalyze log files: count lines by level (ERROR, WARN, INFO, DEBUG, TRACE) and see sample lines.Error Pattern CheckerFind log lines that match a pattern: plain text or regex. Get matching lines with line numbers.Log Format ValidatorValidate that each log line matches an expected format (regex). Paste logs, enter pattern, get invalid lines.

FAQ
- Does Log File Analyzer replace grep?
- It scores and samples a paste. It is not streaming tail -f and will cap large files.
- Will Apply Patch Checker modify my project?
- No. It validates patch text. Nothing is written to disk on the server.
