Cyclomatic complexity linter

Check for overly complicated expressions. See cyclocomp() function from {cyclocomp}.

Usage

cyclocomp_linter(complexity_limit = 15L)

Arguments

complexity_limit

Maximum cyclomatic complexity, default 15. Expressions more complex than this are linted.

Examples

# will produce lints
lint(
  text = "if (TRUE) 1 else 2",
  linters = cyclocomp_linter(complexity_limit = 1L)
)
#> <text>:1:1: style: [cyclocomp_linter] Reduce the cyclomatic complexity of this function from 2 to at most 1.
#> if (TRUE) 1 else 2
#> ^

# okay
lint(
  text = "if (TRUE) 1 else 2",
  linters = cyclocomp_linter(complexity_limit = 2L)
)
