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()

Examples

# will produce lints
lint(
  text = "1:3 %>% mean %>% as.character",
  linters = pipe_call_linter()
)
#> ::warning file=<text>,line=1,col=9::file=<text>,line=1,col=9,[pipe_call_linter] Use explicit calls in magrittr pipes, i.e., `a %>% foo` should be `a %>% foo()`.
#> ::warning file=<text>,line=1,col=18::file=<text>,line=1,col=18,[pipe_call_linter] Use explicit calls in magrittr pipes, i.e., `a %>% foo` should be `a %>% foo()`.

# okay
lint(
  text = "1:3 %>% mean() %>% as.character()",
  linters = pipe_call_linter()
)
