# YAL (Yet another logger)

This repo contains a logger library which I created for my personal arduino / ESP projects

This logger requires C++17 and thus a specific xtensa and platformio

version has to be used.

### ESP8266

In your `platformio.ini` insert the following lines: 

```ini

build_flags =

    -std=gnu++17

    -DYAL_ARDUINO_SUPPORT=true

```

* YAL_ARDUINO_SUPPORT must set so `yal` is not defining arduino functions 

  which are normally defined for testing

* -std=gnu++17 sets the compiler compatibility to C++17

The pinned version is necessary to have the correct compiler versions 

for C++17 support.

An example platformio project can be found in the `platformio` subfolder

### Other platforms

No official support for other platforms exist. 

If you need support, feel free to open an issue.

## Available Loggers 

* Arduino MQTT

  * This depends on the `MQTT` library 

* Arduino Serial

  * No deps are required

## Format

Each appender can be configured with its own format.

Possible options are:

 * `%t` time

 * `%m` message

 * `%c` context

 * `%l` level

For example to configure a format which prints the level and the message

The format defaults to `[%t][%l][%c] %m`.

If no context is given for an appender `default` will be used
