0.9.0 - 2024-05-24

Changelog

Added

  • Added "s" key binding to capture a screenshot of the current screen.
  • Support for strace log files; added "strace" custom timestamp format, which also accepts leading process id integer on each line.
  • --autoclip command-line option, to clip merged output to the first and last timestamps found in the first log file.
  • --show_clock command-line option, to show a running clock in the header of the interactive merged log display.

Changelog

Added

Fixed

  • Some Python version incompatibilities in type annotations (Issue #33)

0.7.0 - 2023-10-07

Changelog

Added

  • Support for CSV input files. logmerger looks at the first column of the CSV for the timestamp.

  • Early detection of end-of-time-range, without reading the remainder of the input file.
  • Notification when loading a large log file is complete.
  • Bell when pressing N or P without defining a search string using F.
  • Timestamps in log files that are marked with "+/-nnnn" or "Z" timezone indicators are converted to local time.
  • Changelog links in CHANGELOG.md.

Fixed
