Diagnose Writes to the Global Environment

Flags a <<- whose target binds in neither an enclosing function nor the package, and so reaches .GlobalEnv. A closure updating its parent, or a package-level cache, is not flagged.

Usage

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

Arguments

path

Character. Path to the package directory. Default: ".".

verbose

Logical. Print diagnostic output. Default: TRUE.

parsed

Optional pre-parsed source, as returned internally by the orchestrator. Defaults to parsing path afresh.

Value

checktor_check_result() with passed, issues, message.

See also

checktor(), which runs this and every other check.

Examples

pkg <- example_diagnose_scenario("code_examples/tf_usage_bad.R",
                                 show_content = FALSE)
diagnose_globalenv_modification(pkg, verbose = FALSE)$passed
#> [1] TRUE
