(Discussion): Split Class/Property decorators plugin (Stage 2) from Stage 0 proposal

[DrewML]

The decorators plugin currently enables support for the following proposals:

• Class/Property decorators: Stage 2
• Method Parameter decorators: Stage 0
• Function Expression decorators: Stage 0 (Don't think this is implemented yet, but may come in the future)

Is anyone opposed to breaking these out to separate plugins?

I didn't realize we supported function expression decorators, are you sure?

Updated the OP - I got that backwards. We currently support method param decorators, but not function expression decorators.

If the proposals are splitted, we should also have seperate plugins I think. But we should be carefully and not break users currently using decorators already. So maybe 3 new plugins and leave the current decorator plugin as is?

Please don't forget that spec still can have breaking changes so we probably need to think about naming before publish. This is unlikely will affect parser but anyway..

babel-plugin-transform-decorators-legacy2? 😄

Ref babel/babel#4955

• remove stage presets
• independently versioned transforms in a separate monorepo, move to main repo after es20xx
• expose parser plugins externally with a whitelist, make syntax plugins independent from babylon core.

#587 with the decorators2 plugin handles Class/Property decorators: Stage 2

[hzoo]

I think decorators2 already disallows the other two so we can close this?
