📎 Add configuration option to remove semicolons

[michaelhays]

Description

Prettier has the option to remove semicolons from your code, except for in certain instances to prevent changing the meaning of the code.

It would be great to have this as a configuration option for Rome, particularly to help the adoption rate for existing codebases that don't use semicolons.

(Creating this issue as a continuation of a discussion in this project, to track interest in adding this option)

This has been a much requested feature. @rome/staff How hard would this be to implement?

[SuperchupuDev]

would this also add the ability to add semicolons?

[sebmck]

@SuperchupuDev I'm not sure I know what that means? This issue is for a configuration option that causes semicolons to be omitted when they aren't necessary. Similar to the prettier option.

nevermind, i was talking about something like the semi option from prettier to add instead of removing semicolons even if they aren't necessary, but looks like rome already does the same by default. maybe the configuration option described by this issue could be a semicolon option (that can be set to false) instead of a no-semicolon option? sounds more intuitive

I don't expect it to be too complicated. It's probably a day or two of work.

This is prettier's logic that we can us as a starting point.

Let's see how today goes. Maybe I'll find some time to look into it.

I love the idea of Rome but cannot use the VS Code extension because semicolons. ☹️

They clearly understand the need for this, please be patient!
