Pipe call linter

Force explicit calls in magrittr pipes, e.g., 1:3 %>% sum() instead of 1:3 %>% sum. Note that native pipe always requires a function call, i.e. 1:3 |> sum will produce an error.

Usage

pipe_call_linter()

# will produce lints
lint(
  text = "1:3 %>% mean %>% as.character",
  linters = pipe_call_linter()
)
#> <text>:1:9: warning: [pipe_call_linter] Use explicit calls in magrittr pipes, i.e., `a %>% foo` should be `a %>% foo()`.
#> 1:3 %>% mean %>% as.character
