OPM-Common Python bindings

opm-common: Python bindings and embedded Python

This folder contains the Python bindings for the OPM-common module and code required for using embedded Python with OPM.

• For the Python bindings, see also the Python bindings of opm-simulators.

• For the Python bindings and embedded Python code, see the documentation.

• To enable tooltips for embedded Python code (opm_embedded) for the editor VS Code, first make sure the stub file in <opm-common-folder>/python/opm_embedded/__init__.pyi is updated! You can recreate this stub file by executing

   stubgen -m opmcommon_python -o . && cat opmcommon_python.pyi | sed "s/class Builtin:/current_ecl_state: EclipseState\ncurrent_report_step: int\ncurrent_schedule: Schedule\ncurrent_summary_state: SummaryState\n\nclass Builtin:/" > NAME-OF-OUTPUT-FILE.pyi
  

  in <opm-common-build-folder>/python/opm. To execute stubgen, "mypy" is needed; this can be installed with "pip install mypy".

  The above stubgen command will create the stub file opmcommon_python.pyi. The cat command will copy the stub file opmcommon_python.pyi to "NAME-OF-OUTPUT-FILE.pyi" and add the lines

   current_ecl_state: EclipseState
   current_report_step: int
   current_schedule: Schedule
   current_summary_state: SummaryState
  

  Then:

  • Either: Build the module opm-common and install it with "make install" - this will copy the file <opm-common-folder>/python/opm_embedded/__init__.pyi to the location where opm_embedded is installed, making it visible to VSCode.
  • Or: Copy the file <opm-common-folder>/python/opm_embedded/__init__.pyi into the folder defined in variable python.analysis.stubPath of VS Code and rename it to opm_embedded.pyi.

• So: When updating any classes or documentation here, please also update the stub file located in <opm-common-folder>/python/opm_embedded/__init__.pyi!
