[enhancement] add .editorconfig support

[rbirkelbach]

Hello,

would it be possible to add .editorconfig support for rstudio? See here: http://editorconfig.org/
If possible, a second improvement would be to add an .editorconfig file to each new rstudio project with sane defaults (e.g. use Hadley Wickham's styleguide).
This would make collaborating much easier and nicer.

Thanks!

We're big fans of .editorconfig (see e.g. https://github.com/rstudio/rstudio/blob/master/src/cpp/.editorconfig). :-) No ETA yet but this is on our wishlist too!

Would this mean that StripTrailingWhitespace, UseSpacesForTab and NumSpacesForTab be removed from .Rproj? If so, the argument behind that would be to separate style settings from others, which may be more personal for each RStudio users, correct?

[jmcphers]

.editorconfig is part of the project, just like .Rproj -- so it doesn't really make it personal for each user. The goal is to keep the style consistent in the project. .Rproj helps with that as long as all the collaborators are using RStudio. .editorconfig is similar, but it is more flexible (you can set defaults per directory and per filetype, for instance) and is supported by many editors other than RStudio.

Yes, I know. What I'm wondering is whether those non-personal, project-wide editor settings will be moved from .Rproj to .editorconfig? Currently, the former is sometimes not commited because it also contains settings which seem more personal (...Workspace & ...History). Unfortunately, such concerns then make it harder to keep the non-personal style elements consistent across different contributors.

Maybe instead of embedding editorconfig in RStudio, it would be easier (I don't know, it's just an idea) to create a translator from editorconfig to rstudioprojects and the other way around?
