Adding SaveConfig().

[g3rk6]

It would be nice to have a way to store configuration into a file. There could be better way of doing it, but this is the version that works for me.

defer should after check error?

Fixed it. Thanks for pointing it out!

LGTM 👍 . Just needs docs.

EDIT: Would also close #33 .

Thanks for the contribution!
I love this idea, and the approach, but I think the PR needs some tweaking.

A few suggestions:

• Remove the debug line you left in
• Create a function in util.go that is called marshallConfigWriter
  It would do the opposite of the unmarshallConfigReader function presently there
• Expand your current code to handle the additional types (hcl & prop)
• rename SaveConfig to WriteConfig()
• perhaps add another function called SafeWriteConfig() which only writes when the file doesn't currently exist.
• Add some tests. Afero would be very helpful here.
• Add some docs. It's a great feature, people should know about it.

I think you've done most of the work already, it's just mostly a question of reorganizing things.

Let me know if you want help or have questions. Happy to help.

This idea is six months old, so I'd assume this PR is dead?

@g3rk6 hi, anything (other than time) blocking you from progressing in this front ?

[g3rk6]

Sorry for the long delay. At the moment the only issue is time and currently super busy. I'll try to make some progress as soon as I get some time. Thanks.

@g3rk6 I'd love to see this fully implemented. I think it is looking good. A group I am part of may have some time to dedicate to helping with it here shortly.

this is stale and it appears #287 has carried it forward. Closing this.
