This is a fork from the official Frontail. It is intended to work especially with openHAB log files.

• Ability to use Regular Expressions in the highlighting rules definition
• Use of html classes (instead of inline css rules) to define the appearance in a separate css file
• Custom highlighting rules, intended for openHAB
• New theming function, allowing to switch between light and dark mode in the same page (instead of having to choose among the two)
• Use of HTML Web Storage API to remember the last used theme

It started as a personal modification on the Frontail installation in my openHABian, the full story is in the first post of this thread: https://community.openhab.org/t/frontail-custom-theme-coloring/116673

Long story short, some modifications where made to the following files:

web/index.html
web/assets/app.js

And some files were added:

preset/openhab_AEM.json
web/assets/styles/openhab_AEM.css

Thanks to the work of Ethan Dye this is also the standard Frontail version on OpenHABian starting from version 1.6.4: you can install it using openhabian-config, menu 21.

Thanks to Grzegorz Miasko who contributed with new rules and color theme. See his GitHub repository here.

I would also like to thank Schnuecks for helping me and giving some great suggestions. He also created a Repository for the installation via docker image, you can find it here.
