class Detector::Perl::Cli

Overview

Detects Perl command-line apps via Getopt::Long / Getopt::Std, App::Cmd, MooseX::Getopt, Getopt::Long::Descriptive, MooX::Options, or explicit @ARGV indexing. Never gates on bare %ENV (Mojolicious/Dancer2 config).

Defined in:

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.
