logmerger 0.13.0

Added

• Added progress indicator when displaying data for large data files.

• Added "I" key binding to display information about the input log files.

• The "go to line" function now accepts 0 or 1 to go to the first line.

Changed

• logmerger 0.13 drops support for Python 3.9, as it makes use of features added in Python 3.10

• Used batched terminal updates for displaying table data, greatly improving performance when displaying large data sets.

• Second performance improvement when displaying line numbers using the --line_numbers option, by pre-padding the values with spaces instead of using textual's automatic column resizing.

• Changed linear search for inserting out-of-order log lines to use binary search using the bisect module.

• Timestamp parsers that matched on milliseconds with 3 decimal places only now match on timestamps with 1-6 decimal places.

logmerger 0.12.0

Fixed

• Fixed packaging configuration so that logmerger modules internally refer to other logmerger modules properly. (Issue #49)

logmerger 0.11.0

Added

• Added support for .jsonl files, containing JSON object per-line. If orjson package is installed, it will be used for JSON parsing, else the stdlib json package will be used.
• Better handling of empty log files.
• New release of the textual package added support for Ctrl-p to select from a list of color palettes.
• Added support for Python 3.14.

Fixed

• Fixed bug when canceling from Jump, Go to line, and Go to timestamp dialogs.

logmerger 0.10.0

Added

• Added --ignore_non_timestamped command-line option, to discard any log lines that do not
  have a timestamp. (Issue #42)
• Added support for Apache Log timestamp format [Fri Dec 01 00:00:25.933177 2023]. (Issue #36)
• CI automated unit tests across all supported Python versions (3.9-3.13).

Fixed

• Fixed timestamp parsing that broke in Python versions pre-3.11. (Issue #43)
• Fixed bug when reordering out-of-order log lines that duplicated a previously-merged
  timestamp.
• Faster loading of data, by reducing instances where sorting is required in the readahead window.
• Fixed hanging bug when piping output to a text file.
• Piping output to a file now uses -width setting if provided.

logmerger v0.9.0

• 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.
• Added SECURITY.md and security vulnerability reporting guidance in README.md.
• Added Python 3.13 support.

logmerger 0.8.0

Added

• Jump forward/backward by number of lines, or by time interval in microseconds, milliseconds, seconds, minutes, hours or days.
• Support for --inline command-line option, to merge logs into a single column instead of side by side. (Issue #32)

Fixed

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

logmerger 0.7.0

Added

• Support for CSV input files. logmerger looks at the first column of the CSV for the timestamp.
• Table displays and updates while loading data.
• 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

• Log lines containing rich-style text tags could raise exceptions in several output modes. Now tag introducers
  in lines are '' escaped before sending to rich or textual.

logmerger 0.6.0

Thanks to the assist from PyPI admins, I've been able to reupload this project using its new underscoreless name logmerger, to match its installed project name and command line command. So it can now be installed using pip as:

pip install logmerger

I've updated all the old name instances I could find in examples, help text, READMEs and docs, but otherwise there are no functional changes in this release.
