Function UnquoteYAMLKey

pkg/workflow/yaml.go:164–188

UnquoteYAMLKey removes quotes from a YAML key at the start of a line. The YAML marshaler automatically adds quotes around YAML reserved words and keywords to prevent parsing ambiguity. For example, the word "on" is a YAML boolean value, so the marshaler outputs it as "on": to distinguish it from th

(yamlStr string, key string)

//	result := UnquoteYAMLKey(input, "on")
//	// result: "on:\n  push:\n    branches:\n      - main"
func UnquoteYAMLKey(yamlStr string, key string) string {
	yamlLog.Printf("Unquoting YAML key: %s", key)

	// Create a regex pattern that matches the quoted key at the start of a line
	// Pattern: (start of line or newline) + (optional whitespace) + quoted key + colon
	pattern := `(^|\n)([ \t]*)"` + regexp.QuoteMeta(key) + `":`

	// Use cached compiled regex to avoid recompiling on every call
	var re *regexp.Regexp
	if cached, ok := unquoteYAMLKeyCache.Load(key); ok {
		var typeOK bool
		re, typeOK = cached.(*regexp.Regexp)
		if !typeOK {
			unquoteYAMLKeyCache.Delete(key)
			re = regexp.MustCompile(pattern)
			unquoteYAMLKeyCache.Store(key, re)
		}
	} else {
		re = regexp.MustCompile(pattern)
		unquoteYAMLKeyCache.Store(key, re)
	}
	// Use ReplaceAllString with capture group references for a single-pass replacement.
	// ${1} = line start (^ or \n), ${2} = optional whitespace
	return re.ReplaceAllString(yamlStr, "${1}${2}"+key+":")
}

// UnquoteYAMLTopLevelKey removes quotes from a YAML key only when it appears
// at the very start of the YAML content.
