LogSynth v0.2.0

LogSynth v0.2.0

New Features

• Per-stream rate configuration - Control rates independently when running multiple streams

  logsynth run nginx redis --stream nginx:rate=100 --stream redis:rate=20 --duration 5m
  

• Jinja2 templating - Use {{ field }} and {% if %} syntax for complex patterns (auto-detected)
  pattern: |
  {% if level == "ERROR" %}ALERT {% endif %}{{ ts }} {{ level }}: {{ message }}
• Conditional field generation - Generate fields only when conditions are met
  error_code:
  type: int
  when: "level == 'ERROR'"
• Configuration profiles - Save and reuse settings
  logsynth profiles create high-volume --rate 1000 --format json
  logsynth run nginx --profile high-volume
• Plugin system - Extend with custom field types in ~/.config/logsynth/plugins/

Improvements

• Docker support with multi-stage build
• 24 new CLI integration tests (106 total)
