Change to separate customizations for formatters

[mzuther]

Hi!

I just stumbled on issue #131 and thought about your comment:

Wow, we should really find a way to make it easier to configure format-all.

When using Emacs' customization dialogs, currently a huge list of formatters is saved. Without looking at your code, I see the following problem:

1. it's not straight-forward to customize a single formatter
2. users with customized formatters won't be able to see and use formatters newly introduced by updates
3. or you'll have to add a lot of code to ensure that 2. does not happen

In other words, you have acquired some code debt. :smile:

I therefore suggest that you move from format-all-default-formatters to separate customizations such as format-all-formatter-python. This sounds like a nice task for LISP macros, although I'm not too familiar with elisp.

Best,

Martin

I agree that's the best move.

• format-all-default-formatter-for-python
• format-all-default-formatter-for-ruby
• ...

That lets people choose from a menu as well. The Python setting can have a menu of black and yapf.

format-all-formatters should still stay for fine-grained control.

Still haven't got around to this :-/ If anyone wants to try their hand at a PR, please let me know.
