Rough Checkpoints

  • Checkpoint 2: Improvements and Verification
    • optparse improvements (figure out good command line syntax)
    • Merging multiple log files
      • With same format
      • With different formats
    • Add unit tests(HUnit)
    • Remove "error" on parse issues, replace with "Maybe"
    • Add -Weverything flag
    • fileembed with actual data + setup of regression tests
    • Add Github CI (optional)
  • Checkpoint 3: Performance
    • Use Vector/Text
    • Use heap for low memory consumption/Use streaming library
    • Benchmarks(optional)
  • Checkpoint 4: Stretch goals
    • Adding quickcheck testing(how to model strftime/log file inputs)
    • Pull in remote files
    • Terminal coloring
      • Filename prefixing in output
      • Text marked as a specific color (eg. log warn levels)
    • Print output in a range of timestamps
    • Group lines without timestamps
    • Reading log files in parallel
    • Look into doctest to clean up unit tests
