class Analyzer::Dart::Cli

Overview

Surfaces the command-line attack surface of Dart programs as cli:// endpoints: the args package (ArgParser / CommandRunner) plus main(List) argv and Platform.environment. Line-scan, merged by URL.

Defined in:

analyzer/analyzers/dart/cli.cr

TEST_PATH_RE = Regex.union("/test/", "_test.")

Per-path test-file gate. A precompiled Regex.union (PCRE2 JIT) replaces the two OR-ed String#includes? scans it used to run — provably equivalent since union auto-escapes each literal.
