Hi!

Today, I would like to announce a new package [LoggingFacilities.jl](https://github.com/tk3369/LoggingFacilities.jl). It’s somewhat experimental at the moment but I would like to hear any feedbacks/thoughts.

# 🔨 What is it?

I love [LoggingExtras.jl](https://github.com/oxinabox/LoggingExtras.jl) because it gives me the ability to compose loggers easily. One of the most powerful feature is TransformerLogger, for which one can take a log record and transform it however you want.

Building on top of that, LoggingFacilities.jl provides additional ammunition to do transformations easily. For examples:

- Inject a string at the beginning (or end) of the message string
- Migrate the kwargs by appending them to the message string
- Migrate log level or message string to the kwargs (useful for JSON logging)
- etc.

# 🔋 Batteries included ™

Broadly speaking, two batteries are included:

1. A standard API to perform transformations (inject, migrate, mutate, and remove)
2. A set of common transformer loggers e.g. OneLine, JSON, Timestamp, etc.

# 🙏 An invitation to try out!

Please go ahead and take a look at the repo. Try if out if you want to produce better logs for your processes. Any bugs… just file an issue.
