# Logging2

[![Build Status](https://github.com/JuliaLogging/Logging2.jl/workflows/CI/badge.svg)](https://github.com/JuliaLogging/Logging2.jl/actions)

**Logging2** is a library which extends the standard Julia

[Logging library](https://docs.julialang.org/en/v1/stdlib/Logging) with

additional functionality. The intent of this library is to consolidate some

of the more useful "core" logging functionality from the wider Julia ecosystem,

and serve as a staging area to improve the logging standard library itself.

## How-To

### Redirect stdout or stderr to the logging system

Use `redirect_stdout` or `redirect_stderr` to redirect all strings written to

`stdout` or `stderr` to any `AbstractLogger` during the execution of a given

`do` block:

```julia

logger = current_logger() # or construct one explicitly

redirect_stdout(logger) do

    println("Hi")

    run(`ls`)

end

```

Note that `stdout` and `stderr` are **global** streams, so this logging choice

is made globally for the whole program. Therefore, you should probably only do

this at the top level of your application (certainly never in any library

code which you expect to run concurrently).
