The logging support is provided by rust's log crate, it only supports the currently implemented levels

[naturallymitchell]

notice, alert, critical, emergency
colors matching 3rd image

[naturallymitchell]

remove log bindings and from lib.rs
keep torchbear's own logger
use log.lua in lighttouch-libs

[naturallymitchell]

log.lua add levels ^^
ansicolors.lua add colors

underline action/rule/event name
put event, action, rule prefix in [] brackets

[naturallymitchell]

actions and rules should have log messages including their priorities

[naturallymitchell]

fwiw,

There are only 256 colors available in terminal. So I couldn't match every color perfectly

There is strange 'bug' that we cannot use functions from Lua debug library so log.lua can't print messages with info about file and number of line

From @aleksanderwlodarczyk on October 14, 2018 11:45

debug isn't working because we are using rlua and they had deleted it from rlua

There are much more than that :)
Check this.

(yeah, handling color support properly is a tricky business)
