# co-log-simple


## Synopsis

Simple enhancements for logging with co-log


## Description

A library built upon co-log that makes constructing and using `LogAction`s
simpler with some predefined formatters and a slightly enhanced Severity type

This library expresses some logging needs that recur in my work:

1. Often I want more than one type of "info" severity to differentiate between
   more- or less-chatty output that's not debug or warning/error related. This
   library includes a new Severity type that adds Notice between Info and
   Warning.
2. I've often wanted different colors for severities which is much easier with
   co-log than hslogger
3. This library also includes some functions for formatting different parts of
   a log message like the severity, stack info, or the message itself. These
   formatters can be composed together with the (%) and (%+) operators.

Additionally:

I found using the RichMsg/RichMessage types in co-log to be slightly on the
complicated side to use. This library integrates timestamping through those
types as well to make things easier while keeping the interface simple.

co-log-simple uses the ISO8601 with zone offset format for timestamps by
default which I like because it sorts. The time formatters in this library also
support custom format strings as defined in the Data.Time.Format module in the
base time library.

For usage examples, see `src/examples/Main.hs` and the API docs for
`Colog.Simple`


## Development

Source code is available from Codeberg at the
[co-log-simple](https://codeberg.org/dinofp/co-log-simple) project page.

Handy command to generate Haddock docs during development if using stack. This
constrains doc generation to modules in the library:

    $ stack haddock --haddock --no-haddock-deps
