--help defaults values doesn't updated with default config files

[stasbel]

Thanks for the full --help command.
Couple of small problems I have spotted so far:

• Arguments order is sorted alphabetically (not with respect to time added). Probably related to --print_config preserve original order #46.
• Output contains python objects info, like ... object at 0x7f3670c6dc50.
• Default values aren't update with having default config files.

* Arguments order is sorted alphabetically (not with respect to time added). Probably related to #46.

In the help I do normally see them in the correct order. It depends on time added and argument groups. Each ActionParser becomes a group so all its arguments should appear together in time added order plus its argument groups. If you can confirm that the order is incorrect, please create an issue with code to reproduce it.

* Output contains python objects info, like `... object at 0x7f3670c6dc50`.

I guess this is because of the ActionParser not being given a title. If you give a title it will look okay. Later I will fix it so that if it is not given a title then nothing is shown.

* Default values aren't update with having default config files.

From what I see this does work correctly. Note that if no file matches any of the patterns in default_config_files then there is no error or warning. The test I did is the following. First create a file config.yaml with content op: from yaml. Then in the same directory run:

>>> from jsonargparse import ArgumentParser
>>> p=ArgumentParser(default_config_files=['config.yaml'])
>>> p.add_argument('--op', default='from default')
>>> p.parse_args([])
Namespace(__default_config__=Path(config.yaml, cwd=/home/***), op='from yaml')

Observe that the Namespace includes a __default_config__ entry which is a way to know which default config file was loaded.

This is now fixed in the current version in master.

Sorry, what I really meant is: "Default values for --help message aren't update with having default config files."

My bad. It was clear from the issue title. This can be done.

In the new release v3.8.0 in the help the titles are no longer object references and the default values are updated from a default config file if present.
