A flexible and extensible logging system inspired by the Python logging module.

For common logging tasks this logger library has a Quick-API which makes it very easy to integrate and use it in a project without caring about the LVOOP internals. The library provides five log levels (DEBUG, INFO, WARNING, ERROR, CRITICAL) and two targets for the output (file handler, event handler). Because of the LVOOP design it is flexibly usable and every part of it can be extended with custom child classes to implement new features.

This software is published under a free licence, you can use, modify and extend it as you wish. However, if you need commercial support please contact us. We also offer packages to extend the basic functionality (e.g. log rotate for files).

Release Notes (Jan 26, 2021)



Corrects the error handling of the log-helper VIs when the Logger is *not* initialized:

If there is no input error
* All helper VIs (DEBUG, INFO, WARNING, CRITICAL, ERROR) will output the "logger not initialized" error.

If there is an input error
* DEBUG, INFO and WARNING will output a duplicate of the input error (i.e. input-error passthrough)
* CRITICAL, ERROR will output a "logger not initialized error"

Special thanks to John Medland for this contribution!
