Rstudio: Whitelist .github/ directory, i.e. show it in the files pane

[jennybc]

.github/ is a standard location for files such as a code of conduct, contributing guidelines, issue templates, and the like:

https://help.github.com/articles/helping-people-contribute-to-your-project/

We just started keeping them there by convention for tidyverse and r-lib packages, as implemented in the usethis::use_tidy_github() function.

But now I realize that this directory is hidden by RStudio 😔. Could it be added to the whitelist?

The only issue I have with the practice of using <.foo> for metadata is that it will be hidden by default in the system shell (e.g. Finder on OS X) or in other editors/applications (save for on Windows where the . prefix has no meaning).

So while it's great that we can one-off whitelist . files in RStudio, it seems to me that if we think it's important enough to be user-visible in RStudio then it probably should be user-visible in other applications/contexts (and therefore not have a . prefix but rather something like _github.

Just my 2 cents. There is already a lot of use of . prefixes in the R ecosystem which ends up working out well for RStudio users (when we whitelist) and Windows users, but not so well for other users.

In this particular case, .github/ is explicitly endorsed as the directory to use for GitHub-related state: https://blog.github.com/2016-02-17-issue-and-pull-request-templates/

Since this convention has been adopted externally I think it's okay to accommodate it explicitly in RStudio.

Okay, agree 100%!
