Support for nextflow logs in the Logfile Navigator (a terminal-based log file viewer)

[tstack]

Hello, I just wanted to mention that I've added basic support for nextflow logs to the Logfile Navigator (https://lnav.org). lnav is a log file viewer for the terminal that can tail, merge, highlight, and analyze logs of a wide variety of formats. Here is a screenshot of a nextflow log:

lnav uses JSON files to define a format, so you can install lnav, download nextflow_log.json, and then run the following to install the file:

lnav -i nextflow_log.json

Alternatively, you can download a nightly build of lnav that will have the format builtin.

Viewing a file is just a matter of passing the paths/globs of the files or directories to open, like so:

lnav .nextflow.log

(lnav will automatically detect the file format, decompress files, open new files in a directory, etc...)

I'm not familiar with nextflow, so I'm not sure if some extra highlighting or other things would be useful. If folks have suggestions, I'm happy to try and implement them.

Thanks
