as well as a new short formatter ShortColorFormat
to help add a bit of color to your otherwise excellent log lines.

shard.yml
:dependencies: cr-color-logging: github: vici37/cr-color-logging
-
Run
shards install
Usage
require "cr-color-logging"
# This will output all debug and above severity log lines to STDOUT, colored via the ShortColorFormat formatter.
# By default, no colors are set and must be defined.
Log.setup(:debug, Log::IOBackend.new(formatter: Log::ShortColorFormat))
# Define the color you want for which part of the log message. Colors
# are the same as the ones defined in the `colorize` module.
Log::ShortColorFormat.with_color("severity", :red)
Log::ShortColorFormat.with_color("timestamp", :blue)
# Outputting a log now is as simple as:
Log.for(MyClass).info { "my information message" }
The full list of parts that the ShortColorFormat
supports are:
timestamp
message
severity
source
after_source
before_data
data
before_context
context
exception
progname
pid
string
The ShortColorFormat
was defined using the same string as the standard ShortFormat
here. A similar macro is also defined for the ColorLogging
module to define custom formats as well:
ColorFormat.define_formatter MyFormat "#{timestamp(after: ":")} #{severity(before: "[", after: "]")} #{message}"
# All parts, with exception to `string`, support a before_ and after_ prefixed part to color those
# specific pieces. If omitted, they inherit from the base part.
MyFormat.with_color("before_severity", :yellow)
MyFormat.with_color("after_severity", :yellow)
MyFormat.with_color("severity", :red)
# It might also be good to skip specific part coloring if a log line is of a sufficient severity.
# This will color the entire line this color if the severity matches.
MyFormat.with_colored_sevirity(Log::Severity::Error, :red)
