heat.common.template_format.convert_json_to_yaml(json_str)[source]¶

Convert AWS JSON template format to Heat YAML format.

Parameters:	json_str – a string containing the AWS JSON template format.
Returns:	the equivalent string containing the Heat YAML format.

heat.common.template_format.parse(tmpl_str, tmpl_url=None)[source]¶

Takes a string and returns a dict containing the parsed structure.

This includes determination of whether the string is using the JSON or YAML format.

heat.common.template_format.simple_parse(tmpl_str, tmpl_url=None)[source]¶

heat.common.template_format.validate_template_limit(contain_str)[source]¶

Validate limit for the template.

Check if the contain exceeds allowed size range.
