Examples

# will produce lints
code <- "box::use(package)
tidyr::pivot_longer()"

lintr::lint(text = code, linters = namespaced_function_calls())
#> <text>:2:1: warning: [namespaced_function_calls] Explicit `package::function()` calls are not advisible when using `box` modules.
#> tidyr::pivot_longer()
#> ^~~~~~~~~~~~~~~~~~~

## allow `tidyr::pivot_longer()`

# okay
