This version of STELLOPT makes use of make_***.inc files in the SHARE subdirectory to set various options at compile time. The make.inc file in the main directory is a script which picks these files based on what is returned by the uname -n command on your machine. This can be overridden by setting the environment variable MACHINE to the file you wish to use. For example to use SHARE/make_bobdole.inc you would set MACHINE=bobdole before calling the build scripts. It is also important to set STELLOPT_PATH to the path to your current directory where you've pulled the repository.

Once you configure the environment variables, you can begin to compile the code by

 ./build_all 

By default, it will compile all the codes in the folder with the option clean_release. You can customize the script by providing additional commandline arguments, like ./build_all -o release -j 4 STELLOPTV2. To check the options, type ./build_all -h.

There is also a Docker image available for use at https://hub.docker.com/r/zhucaoxiang/stellopt.

For more information, please view STELLOPT compilation.

Once a working copy is developed for your computer, you are welcome to push it back to the main repository for other users. You can ask for a write permission and push your changes into a remote branch. Then submit a pull request through GitHub.

Or you can share your changes via git fork, which doesn't require you have the write permission.

GitHub actions will be triggered by each push and pull-request. The code will be compiled with debug option and you can check the full log at GitHub actions.

A Python interface using CTYPES is also included but it requires a static shared build of LIBSTELL. This is still a highly experimental option. You can find the python scripts at ./pySTEL.

There are also some other plotting packages developed by group members. Here are some examples.

• matlabVMEC: MATLAB packages for various codes.
• coilpy: Python package for toroidal Fourier surface, coils, FOCUS and STELLOPT.
