Function preprocessBoolFieldAsString

pkg/workflow/config_preprocessing.go:20–42

preprocessBoolFieldAsString converts the value of a boolean config field to a string before YAML unmarshaling. This lets struct fields typed as *string accept both literal boolean values (true/false) and GitHub Actions expression strings (e.g. "${{ inputs.draft-prs }}"). If the value is a bool it i

(configData map[string]any, fieldName string, debugLog *logger.Logger)

// with "${{" and ends with "}}"); any other free-form string is rejected
// and an error is returned.
func preprocessBoolFieldAsString(configData map[string]any, fieldName string, debugLog *logger.Logger) error {
	if configData == nil {
		return nil
	}
	if val, exists := configData[fieldName]; exists {
		switch v := val.(type) {
