Diagnose Print/Cat Usage in Functions — diagnose_print_cat

Flags print() / cat() calls not guarded by an enclosing if(), for(), or while(). The check uses the ancestor axis, so guard detection is robust regardless of formatting.

Usage

diagnose_print_cat_usage(path, verbose = TRUE, parsed = NULL)

Arguments

path: Character. Path to package directory.
verbose: Logical. Print diagnostic messages.
parsed: Internal. Pre-parsed source cache; if NULL, files are read from path on demand.

Value

checktor_check_result() with passed, issues, message.

Examples

pkg <- example_diagnose_scenario("code_examples/print_cat_bad.R",
                                 show_content = FALSE)
diagnose_print_cat_usage(pkg, verbose = FALSE)
