interaction with gitignore everything without an extension

[luispfonseca]

I do not know if this is a bug or user error. I have a project using RStan. RStan compiles model code to a binary file without an extension in the name. I don't want this binary file to be committed to git, so I followed a suggestion described here and I have the following block in my .gitignore.

# ignore *everything*
*
!/**/
# and then this 'unignores' anything with an extension
!*.*
# now, the rest of your gitignore should appear after the above
# on windows Stan executables end in .exe
*.exe
# Ignore temporary files created as part of compilation.
*.hpp
*.o

The issue is that renv does not detect any R files in subfolders if I have this in my .gitignore, and thus detects no packages used. This issue does not affect .R files in the root folder of the project; only in subfolders. Is this expected behaviour? I suspect this is not a great use of gitignore, but I'm unsure how to reconcile the two goals here.

Thanks for all the work in the package!

I'm surprised that Stan doesn't give a unique extension to the compiled model files, or something like that... Either way, any divergence between how git and renv interprets the .gitignore file should be considered a bug in renv, so this seems worth fixing.

Regardless, the simplest solution in your case might be to include a .renvignore file, which might include simpler ignore rules. Please see https://rstudio.github.io/renv/reference/dependencies.html#ignoring-files for more details.

This should now be fixed up via 9274c79 -- if you're able to test, please let me know if that resolves the problem for you. Thanks for reporting!

Seems to work now, thanks a lot for the quick fix!
