489686cf5d
In the earlier version of TOSCA Parser the call to entry class TOSCATemplate has two arguments, file path and parameters where parameters arg is optional. A new arg has been added in parser as a flag to check if the path is file or not. The old way of calling parser (e.g. ToscaTemplate(path, '')) will not work with it. Should change the constructor signature per patch. Change-Id: Ia543bcaa6967ae68863266faef9689b1e27f0bf7

CLI test utility to show how TOSCA Parser can be used programmatically
|
|
|
|
This is a basic command line test utility showing the entry point in the
|
|
TOSCA Parser and how to iterate over parsed template. It can be extended
|
|
or modified to fit an individual need.
|
|
|
|
It can be used as,
|
|
#python tosca_parser.py --template-file=<path to the YAML template>
|
|
#python tosca_parser.py --template-file=<path to the CSAR zip file>
|
|
#python tosca_parser.py --template-file=<URL to the template or CSAR>
|
|
|
|
e.g.
|
|
#python tosca_parser.py
|
|
--template-file=toscaparser/tests/data/tosca_helloworld.yaml
|
|
#python tosca_parser.py
|
|
--template-file=toscaparser/tests/data/CSAR/csar_hello_world.zip
