Screenshots (if appropriate):

How Has This Been Tested?

• Given module name and flag key exist without arg:

$ dasel select -f ~/.config/starship.toml -p toml -m '.kubernetes.disabled' # returns 'true'
$ cargo run toggle kubernetes
$ dasel select -f ~/.config/starship.toml -p toml -m '.kubernetes.disabled' # returns 'false'

• Given module name and flag key exist with arg:

$ dasel select -f ~/.config/starship.toml -p toml -m '.kubernetes.disabled' # returns 'true'
$ cargo run toggle kubernetes disabled
$ dasel select -f ~/.config/starship.toml -p toml -m '.kubernetes.disabled' # returns 'false'

• Given module name exist but flag key not exist with arg:

$ cargo run toggle kubernetes show_namespace

See the error: [ERROR] - (starship::configure): Given config key 'show_namespace' must be exist in config file

• Given module name and non-boolean flag key exist with arg:

$ cargo run toggle kubernetes format

See the error: [ERROR] - (starship::configure): Given config key 'format' must be in 'boolean' format

• Given module name not exist:

$ cargo run toggle winamp

This will panic-ed, it works the same as the update_configuration() function. We just ignored the None case, by using this: table.get(keys[0]).unwrap(). Shouldn't we cover the case of None? What about adding a new fatal message like: [ERROR] - (starship::configure): Given module 'winamp' not found in config file

• Given module name and flag key not exist:

$ cargo run toggle winamp volume

Same as above.

• I have tested using MacOS
• I have tested using Linux
• I have tested using Windows

Checklist:

Some help wanted here too! :)

• I have updated the documentation accordingly.
• I have updated the tests accordingly.

**Happy aliases, you astronauts! **

Hey @Dentrax, sorry I've not managed to give this a proper review yet, I'll try to take asap.

I'm not sure what if anything is changing here, is this just a whitespace change? If so is it required?

[Dentrax]

I did not touch here actually, it's so weird that does not show up my name in annotate. Maybe rustfmt did this?

[andytom]

As you mentioned in the PR description I think it would be better if we handled this a bit more gracefully, maybe we could log an error here if the module section is not set in the config file?

[Dentrax]

Good catch! It's done. Now it should log Given module 'winamp' not found in config file and exit(1) in case of error.

LGTM
