Diagnose T/F Usage in R Code

Flags bare T / F symbols that should be TRUE / FALSE. Operates on the parsed AST, so T inside string literals or comments is not flagged (a long-standing source of regex false positives). Named-argument names (f(T = 1)) and $T / @T extractions are excluded.

Usage

diagnose_tf_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/tf_usage_bad.R",
                                 show_content = FALSE)
issues(diagnose_tf_usage(pkg, verbose = FALSE))
