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:

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
