create method abstraction to allow to be called from a module

[tgrecojr]

I created a new method called get_garmin_connect_data in order to more easily allow this code to be called from another python script as a module. The use case here is to be able to script the execution of the downloads in conjunction with other activities (such as parsing and inserting to a database) without having to pass the command in via command line.

The original argument parsing remains intact if called from the command line.

Two thumbs up for the idea! I did a similar implementation in my own fork. Basically moved garminbackup.py to garminexport/garminbackup.py and broke it into two functions. Another difference is that the only argument is a single object args with attributes instead of a long list of specific arguments like username, password, etc. Maybe I should also try my luck with a pull request? ;)

If you could send a PR, that would be awesome! I hope at some point It gets merged. I like your implementation very much — more the “python way”.

Here you go: #44

I am going to close this pull request in favor of #44 by @khrapovs . The idea is the same, but the implementation is better. I would love if you could merge #44 .

Thank you @tgrecojr ! I've taken a look at #44 and am, generally in favor of the idea, but I think the proposal needs some work in order to become a generally useful client API (refer to the review for detalis). Thanks!
