This tool manages configuration profiles for Win32 Environment Variables. It is mainly targeted to shared developer workstation users, who need to change their working environment on a regular bases. Based on a configuration file (see demo_environment.ini), a user describes sections and configurations.

A section is a set of changes that need to be made to support a single application or library. A change request can be any of:

• Add a new Environment Variable (add_keys)
• Remove an existing Environment Variable (remove_keys)
• Prepend an item to the PATH Variable (prepend_path)
• Append an item to the PATH Variable (append_path)

A configuration is an ordered composition of sections. For example if one has a section to support python and a section to support an application with python bindings, then a configuration for this application would consist of the python and the application section (see h3d_minimal in demo-config)

Configurations are installed using the win32 api and are persistent. Whenever a profile is changed, the current active changes are undone before a new profile is installed. The application prevents from being launched multiple times and stores a recovery file to undo changes at the next launch if it happens to exit without cleaning up.

Installation:

• pip install -f requirements.txt
• python setup.py install

Usage:

• envmgr -C path/to/config_file.ini
