Structured Log Viewer

Structured Log Viewer is a fast desktop log analyzer and stream explorer for
JSON-Lines (.jsonl), Nginx and Apache web access logs, and syslog or
timestamped application logs on Linux. Built for backend engineers and
operations teams who want instant filtering, spike visualization, and clean
exports without heavy cluster setups.

Key Features:
- Multi-Format Log Explorer: Parses JSON-Lines (.jsonl and structured streams),
Nginx and Apache access logs, and syslog or timestamped application logs
with instant level filtering (ERROR, WARN, INFO, DEBUG), regex search
highlighting, and a raw surrounding context inspector.
- Time-Bucket Histogram & Top Error Patterns: Renders a timeline histogram
highlighting event and error spikes per minute or hour alongside normalized
template clustering that groups variable numbers and IDs to rank top errors.
- Filtered Log Slice Exporter: Exports filtered and optionally masked log
slices to plain .log, structured .jsonl, tabular CSV, and self-contained
HTML summary reports.
