Detector::Groovy::Cli
Detects Groovy command-line apps via the built-in CliBuilder, picocli annotations, JCommander or Commons CLI. Gated on library-specific constructs/imports only (never a bare generic token) so unrelated code doesn't light this up. Never gates on bare System.getenv (Grails config).
Constants
Class methods
The tech name without needing an instance, so the registry can be read off the classes themselves rather than from a parallel list.
Instance methods
Cheap filename-only filter the detector pass uses to skip
detect on files the detector cannot possibly match. The
default true preserves prior behavior (every detector runs on
every file). Override with the same predicate the body of
detect starts with — e.g., filename.ends_with?(".py") for a
Python framework detector — so the detector loop avoids the
detect dispatch on files outside the detector's language.
On large codebases (saleor's 4255 .py files) this lifts ~100
virtual detect calls per file out of the hot loop because
most detectors' inner first-line is exactly this kind of cheap
filename check.
