check_filename() only shows errors on Github

[ElsLommelen]

When running check_package() or check_filename() locally, I don't get any errors related to filenames, while the Github action check package (inbo/actions/check_pkg@master) gives several errors concerning filenames (due to use of uppercase,...). Locally the following note is added to the output of check_filename() (I'm not sure it has something to do with the problem, but I don't see anything else that could be relevant to solve the problem):

...
[1] C:/R/Library
[2] C:/R/R-4.1.0/library

P -- Loaded and on-disk path mismatch

Probably due to differences in OS handling of case-sensitivity in folder and filenaming? Windows is case-insensitive, while ubuntu is case-sensitive.

[ElsLommelen]

Ah, yes indeed, all errors are due to the use of uppercase (or - vs _).

Is there maybe any possibility to check it locally as well? The default in Windows is indeed case-insensitivity, but in a lot of R functions it is possible to choose for case-sensitivity. It would be helpful to not have to push commits and wait for the checks to find out this type of problems. Also, in case of for instance a warning on the use of - instead of _: how to ignore these using write_checklist() if these warnings do not show up locally?

Do you get uppercase names when you run the code below in your git repo?

library(git2r)
repo <- repository()
ls_tree(repo = repo, recursive = TRUE)

[ThierryO]

Can you check list.files(".", recursive = TRUE, all.files = TRUE) too?

[ElsLommelen]

Yes, I get uppercase names in both cases.

A few more things to check:

• basename("a/A.txt") returns "A.txt"
• grepl("[a-z]", c("a", "A")) returns TRUE, FALSE

If those things work as I expected them to work, then please run debug(check_filename) and check_filename(). And try to see where things go wrong.

Ok, it seems to work fine now: I get the same errors locally and on github.
