SciLogger - Logging for Scientific Applications

• Repository: github.com/otvam/scilogger
• PyPi: pypi.org/project/scilogger
• Conda: anaconda.org/conda-forge/scilogger

Summary

SciLogger is a Python Logging module:

• Specially targeted for scientific applications.
• Use a global timer to measure the elapsed time.
• Provide a class for timing code blocks.
• Definition of custom indentation levels.
• Definition of colors for the logging levels.

SciLogger is using a global INI configuration file:

• First, the default configuration is loaded (scilogger/scilogger.ini).
• Afterward, a custom file can be loaded with an environment variable (SCILOGGER)

SciLogger is written in Python without any external dependencies. SciLogger is respecting semantic versioning (starting from version 1.2).

Warning

• This logging module is based on the Python logging module.
• The philosophy of this logging module is slightly different.
• Mixing both modules can create strange/incorrect behaviors.

Example

An example is located in the example folder of the repository:

• run_logger.py contains an example file for the logger
• configlogger.ini contains a custom configuration file

# Set the configuration file.
export SCILOGGER="configlocal.ini"

# Run the Python script.
python run_logger.py
