Environments

What each framework needs in order to run its models. The recipe is in docs/models/<framework>, shared by all of that framework’s models: env.cfg says how to build it, requirements.txt lists the exact versions, and README.md gives the version used and what it needs. sbml, epipack, and epymorph have a recipe but no models.

What a recipe builds goes in _envs/<framework>, none of which is committed. A model finds its framework at _envs/<framework>/bin, which docs/models/tools.py puts at the front of the PATH.

Installing

lingua_franca envs check                 # Compare what is installed with the recipes
lingua_franca envs install               # Build whichever are missing or incomplete
lingua_franca envs install odin siminf   # Or only some of them
lingua_franca envs key odin sbml         # A hash of their recipes, for caching what they build
python scripts/clean_envs.py             # Delete what was built
python scripts/clean_envs.py camdl       # Or only some of it

It needs Sciris, and whatever the frameworks being installed need (uv, R, or OCaml and Rust: see the README.md of each). It follows the steps in each README.md, and what a build prints goes to build.log in the folder. The Python environments are rebuilt from requirements.txt, so they get exactly the versions used. The R ones get CRAN as it was on the date in src/lingua_franca/envs.py, so to update them, change that date and requirements.txt.
