load nfc2klipper cfg from home directory

[thijstriemstra]

I prefer not to modify the config file in the repository (making it harder to git pull and solve conflicts) so I suggest to place the config in the home directory instead.

I agree, its better to keep a separate file so pulling changes won't risk unnecessary conflicts.

Maybe it is better to use ~/.config/nfc2klipper/config.json5 or ~/.config/nfc2klipper.json5 though to keep $HOME uncluttered.
Some other klipper related programs put their configuration files in ~/klipper_config/, that's also an option.

sounds good. creating that directory and placing the file sounds like something an install script should do, shall i add one?

[bofh69]

Yes, please add one.

the other option is have a nfc2klipper-config.json5.default file in the repo, then add nfc2klipper-config.json5 to the .gitignore file. This way we can copy the default to nfc2klipper-config.json5 and make our own changes and git ignores them. But yes using ~/.config is also an option.

The advantage of the .default copy is people know what options can be in the config.

I implemented toml support (kind of like klipper/moonraker's config files) yesterday and then it reads the config file from ~/.config/nfc2klipper/nfc2clipper.cfg or ~/nfc2klipper.cfg.

See the switch-to-toml branch.

There is no automatic upgrade from the json5 file, but if it doesn't find a config file it copies the included config file.

nice! could you turn the branch into a pull request so it's easier to review?
