Package: glm
glmA fastGridLAB-Dto JSON (and back) parser.Fast GLM to JSON converter.Supports nested objects, schedules, definitions, directives, modules, includes and clock objectsFast JSON to GLM converter.Native support for Python, returns nested dictionaries.Descriptive error messages when unable to parse a GridLAB-D model file.Tested on all examples in the GridLAB-D source repository.InstallGo to thelatest releases pagefor the Python or the CLI for various operating systems.PythonYou can pip install the package from PyPI or using the wheel (files with extension .whl) after downloading it or directly from the URL from the releases page.The following installs the latest glm package for Windows, MacOSX or Linux from PyPI.
This will work for Python2 or Python3.pip install glmThis also installs theglm2jsonandjson2glmcli utilities.DocumentationYou can use this from the command line as follows:Usage:
  glm2json [required&optional-params]
Convert from glm/json to json/glm
