LogLens v0.2.0

Error clustering and export.

Added

• Error clustering engine — groups similar errors and stack traces by frame-structure signature, with volatile-value masking (timestamps, ids, uuids, hex, quoted payloads) and a deterministic merge pass for near-identical messages
• Error clustering view (c) — a ranked panel of clusters with [×N] counts; Enter jumps to a cluster's newest occurrence
• Export (w) — writes the currently filtered view to a file, with exclusive-create safety so an existing file is never overwritten

LogLens v0.1.0

First release of LogLens, a terminal UI for tailing and analyzing multiple log files live.

Added

• Merged live tail across multiple log files, each source rendered with its own color badge
• Per-file format auto-detection: JSON lines, syslog (RFC 3164), nginx (access + error), and a generic fallback
• Level highlighting (DEBUG/INFO/WARN/ERROR) as lines arrive
• Live regex filter (/) that narrows the view as you type
• Errors-only view (e) that keeps a traceback attached to the error line that produced it
• Pause with free scrollback (p)
• Buffer search (s) with n/N match navigation
• Error-frequency histogram (t)
• Log-rotation and truncation handling for tailed files
• Capped 100k-line ring buffer
• Sample log generator script (scripts/genlog.py) for demo traffic

Requires Python 3.10+. Install with pip install -e . from source.
