Example for coloring lines in custom format

[WolleKette]

Currently, I’m writing a config for a custom log format. I’ld like to coloring some lines depending on their loglevel.
Unfortunately, I can't find an example for that in the formats provided. And the documentation for it is a bit short.
Does anyone perhaps have an example of something like this?

The coloring for the log levels is normally controlled by the theme definition. Here's how the colors are in configured the monocai theme:

lnav/src/themes/monocai.json

Lines 255 to 268 in 8d17561

	"log-level-styles": {
	"warning": {
	"color": "$yellow"
	},
	"error": {
	"color": "$red"
	},
	"critical": {
	"color": "$red"
	},
	"fatal": {
	"color": "$red"
	}
	}

You can override the theme's colors in your user configuration with the :config command. The path to pass to the config command will depend on the theme and log level you're modifying. For example, to change the "error" level in the "monocai" theme to a dark red, you would execute:

:config /ui/theme-defs/monocai/log-level-styles/error/color #a22

Thank you very much for the help.
I think that was the little piece of the puzzle that helped me understand the principle of configuration. Really complicated, but quite powerful.
