Functions⚓︎

check_installed ⚓︎

check_installed(ctx, executable, message)

If the required executable isn’t present, raise a clear user error.

Source code in calcipy/tasks/executable_utils.py 
@beartype

    """If the required executable isn't present, raise a clear user error."""

    if not res or res.exited == 1:
        raise RuntimeError(message)

python_dir cached ⚓︎

python_dir()

Runs an executable from the currently active Python directory.

Source code in calcipy/tasks/executable_utils.py 
@lru_cache(maxsize=1)
def python_dir() -> str:
    """Runs an executable from the currently active Python directory."""
    return str(resolve_python().parent)

python_m cached ⚓︎

python_m()

Return the active python path and -m flag.

Source code in calcipy/tasks/executable_utils.py 
@lru_cache(maxsize=1)
def python_m() -> str:
    """Return the active python path and `-m` flag."""
    return f'{resolve_python()} -m'

resolve_python cached ⚓︎

resolve_python()

Resolve the user’s Python path based on sys.

Source code in calcipy/tasks/executable_utils.py 
@lru_cache(maxsize=1)
def resolve_python() -> Path:
    """Resolve the user's Python path based on `sys`."""
    python_path = Path(sys.executable)
