file-specific linter exclusions error

[russHyde]

I have a package with ./tests/testthat/test-style.R and R/style.R and am trying to use the file/linter-specific exclusion setup described here: https://lintr.r-lib.org/articles/lintr.html#excluding-files-completely

If I have a .lintr config at package-root with the contents:

linters: linters_with_defaults()                                                                                             
exclusions: list(                                                                                                                    
    "tests/testthat/test-style.R" = list(semicolon_linter = Inf)                                                                                           
  )

The following error arises:

Error in file_exclusion[[names2(file_exclusion) == ""]] : 
  attempt to select less than one element in integerOneIndex

This results from the following call (from lintr::lint_dir):

path <- "/home/me/blah"
files <- file.path(path, c("R/style.R", "tests/testthat.R", "tests/testthat/test-style.R"))
exclusions <- list(list(semicolon_linter = Inf))
names(exclusions) <- file.path(path, "tests/testthat/test-style.R")

lintr:::drop_excluded(files, exclusions)
#> Error in file_exclusion[[names2(file_exclusion) == ""]] : 
#>   attempt to select less than one element in integerOneIndex

Apologies if I've misunderstood this new exclusions syntax.

I note that someone has raised a related issue in #1413

Using current lintr-master (1a170f5) on the same R package

lintr::lint_package()
Error in file_exclusion[[which(names2(file_exclusion) == "")]] : 
  attempt to select less than one element in get1index

Thanks for reporting. Can you test #1447 on your package just to be sure the bug is squashed for good?

[russHyde]

Thanks. This works great.
