Ideolog ⭐ ⭐

Comes handy to highlight lines belong to different severities in a logfile. Not easy to configure, so here you can find a configuration to process Tomcat log files.

^(\d+-[a-zA-Z]+-\d+ \d+:\d+:\d+.\d+) ([A-Z]+) (\[[a-zA-Z0-9\-\[\]]+\]) ([a-zA-Z0-9.:\/]+) ([a-zA-Z0-9 \[\]"':.,\-=_\/]+)$

The content of the log file looks as follows:

23-Dec-2023 08:21:39.134 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Server version:        Apache Tomcat/8.5
23-Dec-2023 10:45:57.289 ERROR [localhost] org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory [/opt/apache-tomcat-8.5/webapps/ROOT]

This plugin can have more star, though, configuration requires prior knowledge regex and instead of coloring the whole line in green or red, for the better experience, tokenization could be helpful to read logs.

String Manipulation ⭐ ⭐ ⭐

Awesome tool to align, sort, quote or handle strings in a file in any way. Strictly recommended for sorting CSV files or writing markdowns.

It can highlight the output lines like Ideolog, however it can give a lot more. By using regular expressions the output can be filtered against the pattern or vice versa. The plugin brings heavy configuration as well.
