Shtab complete: the action.complete of Classes, methods and functions should be `shtab.FILE`

[tshu-w]

🐛 Bug report

Currently, the action.complete for shtab is FILE only when it is ActionConfigFile or Pathlike for ActionTypeHint, however, these doesn't cover the action of _ActionConfigLoad.

jsonargparse/jsonargparse/_completions.py

Lines 144 to 162 in f5f2422

	complete = None
	if isinstance(action, ActionConfigFile):
	complete = shtab.FILE
	elif isinstance(action, ActionTypeHint):
	typehint = action._typehint
	if get_typehint_origin(typehint) == Union:
	subtypes = [s for s in typehint.__args__ if s not in {NoneType, str, dict, list, tuple, bytes}]
	if len(subtypes) == 1:
	typehint = subtypes[0]
	if is_subclass(typehint, Path):

	complete = shtab.FILE
	elif "d" in typehint._mode:

To reproduce

Simple Example

# cli.py
from jsonargparse import ArgumentParser
from calendar import Calendar

class MyClass:
     def __init__(self, calendar: Calendar):
         self.calendar = calendar

parser = ArgumentParser()
parser.add_class_arguments(MyClass, "myclass", sub_configs=True)
cfg = parser.parse_args()

λ python cli.py --print_shtab=zsh
...
"--myclass[Path to a configuration file.]:myclass:"
...

Expected:

λ python cli.py --print_shtab=zsh
...
"--myclass[Path to a configuration file.]:myclass:_files"
...

since the following command work:

python cli.py --myclass test.yaml

with test.yaml:

calendar:
  class_path: calendar.Calendar
  init_args:
    firstweekday: 1

Environment
