class Detector::Swift::Cli

Overview

Detects Swift command-line applications. SOURCE-anchored (never Package.swift, where swift-argument-parser is a transitive dep): a ParsableCommand conformance, ArgumentParser property wrappers, SwiftCLI / Commander, or builtin CommandLine.arguments.

Defined in:

detector/detectors/swift/cli.cr

Instance Method Detail

def applicable?(filename : String) : Bool #
Description copied from class Detector

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.
