Function ParseBoolFlag

pkg/output/output_setup.go:75–109

ParseBoolFlag scans os.Args backward to apply last-occurrence precedence for a boolean flag. Handles both --long[=true|false] and -s[=true|false] forms. Treats short flag in combined group (e.g. -xj) as implicit true. Returns false if the flag is absent or its value is invalid. Disabled entirely whe
