Modulecmd.py is an environment module system inspired by TCL Environment Modules and Lua lmod and written in Python. Modulecmd.py is compatible with Python 2.6, 2.7, and 3.5+. Modulecmd.py does not require any additional compilation.

Modulecmd.py provides a framework for processing module files written in Python. Additionally, Modulecmd.py processes TCL modules by wrapping the TCL module command. TCL compatibility requires that tclsh be found on the user's PATH (the TCL module command is provided by Modulecmd.py). Likewise, lmod can process most TCL modules.

Clone or download Modulecmd.py. In your .bashrc, execute the following:

source ${MODULECMD_PY_DIR}/share/pymod/setup-env.sh
module init -p=${MODULEPATH}

where ${MODULECMD_PY_DIR} is the path to the directory where Modulecmd.py is cloned. The second command above (module init-p=${MODULEPATH}) instructs Modulecmd.py to do some initialization tasks and is not strictly necessary.
