lnav is a powerful log file reader, designed to take multiple log files and order them by date. It understands log file formats using regular expresions and can highlight sections of line, find errors and warnings, and more.

This repository is for the log file format descriptions I've written so far.

You can install these using lnav -i formatfile.json or by putting them in your ~/.lnav/formats/installed directory.

I now provide a new tool, make_format.pl, which takes a series of lines from stdin and turns them into sample lines in a new format. This can, for instance, be used by marking several significant lines in lnav and issuing the command:

:pipe-to perl path/to/make_format.pl -name example -output example_log.json

Using the -name or -n option sets the name in the format. This is lazy, so you'll need to edit it to suit yourself. If this option is not specified the format name is 'NEW' throughout.

Using the -output or -o option sets the destination for the new format. If this is not specified the result will be written to standard output.
