Description
I have got an interface which expects a parameter foo as a triple with the following format --foo 1 2 3
I reached for the following definition as a first attempt:
input_spec = pydra.specs.SpecInfo(
name="Input",
fields=[
(
"foo",
ty.Tuple[int, int, int],
{
"help_string": "foo triple",
"argstr": "--foo {foo}",
},
),
],
bases=(pydra.specs.ShellSpec,),Which does not work since it produces --foo (1, 2, 3).
If I use --foo... and instantiate the interface with a list instead of tuple then I get --foo 1 --foo 2 --foo 3.
If I use formatter instead of argstr with "formatter": lambda field: f"--foo {' '.join(field)}", I get an error because formatter seem to be called with each element of the list instead of the entire list (TypeError: sequence item 0: expected str instance, int found).
I am probably missing another option, hence this support request 🙏
