[Python-Dev] Re: thes mapping data type and thescfg cfg file module - review and suggestion request

It won't be easy to add this to the stdlib. One thing that bugs me in particular is that you can access key via '.attr' notation (the example shows t['a']['b']['c']['d'] as equivalent to t.a.b.c.d). This feels problematic: What should happen if the key happens to be the name of a method (e.g. .keys or .update)? The choices you have are either to mask the method or to mask the key. Neither solution seems ideal. JavaScript has this equivalence and it makes me very uncomfortable. I'm not denying that Thesaurus[Cfg] looks useful. But, like Tal, I must stress that that's not enough to consider inclusion in the stdlib. On Mon, Nov 18, 2019 at 4:25 PM Dave Cinege wrote:

Hello Tal,

Yes I understand that. I posted this here because it's been suggested by those less in the know that Thesaurus and ThesaurusCfg (or some of the the concepts contained in them) might have a place in the future mainline.

Remember that Thesaurus is a data type and ThesaurusCfg is a alternative to configparser. Additionally I could bring this full circle to something that integrates with or provides an alternative to argparse. (providing an integrated cfg file and command line argument solution which currently does not exist.)

I hope with this in mind this thread is considered on-topic and I'd highly value any feedback from the 'serious people' on this list if they should take a look.

Hi Dave,

Thesaurus looks interesting and it is obvious that you've put a lot of effort into it!

This list is for the discussion of the development *of* Python itself, however, rather than development *with* Python, so it's not an appropriate place for such posts.

I suggest you post this on python-list and/or python-announce, to get this in front of a wider audience.

If you are not aware:

- Thesaurus is a mapping data type with recursive keypath map and attribute aliasing. It is a subclass of dict() and is mostly compatible as a general use dictionary replacement.

- ThesaurusExtended is a subclass of Thesaurus providing additional usability methods such as recursive key and value searching.

- ThesaurusCfg is a subclass of ThesaurusExtended providing a nested key configuration file parser and per key data coercion methods.

The README.rsl will give a better idea: https://git.cinege.com/thesaurus/

After 7 years I might have reached the point of 'interesting' with my Thesaurus and ThesaurusCfg modules.

To anyone that is overly bored, I'd appreciate your terse review and comments on how mundane and worthless they still actually are. :-)

I'm primarily interested in suggestions to what I've done conceptually here. While I'm not completely ashamed of the state of the Thesaurus code, ThesaurusCfg is not far beyond the original few hours I slapped it together one day in frustration.

After considering suggestions I intend to make changes towards a
