Types of changes
Summary
Adds the
pydra.mark.shell_commands.cmd_arg()
andpydra.mark.shell_commands.cmd_out()
methods to streamline the definition of input/output specs for shell command task definitions. Instead of creating an attrs.field by hand and setting the metadata directly,cmd_arg
andcmd_out
do this for you.The main benefit is that
cmd_arg
andcmd_out
specify the valid metadata fields that can be added to the input and output fields, making the code more self-documenting. It also makes the task definitions slightly less verbose.Checklist
