Update error messages so they follow the same format. Also, add i18n where it is missing, fix typo and grammatical errors in messages, and fix vague messages so they are more clear. Change-Id: I06d29b4d8448f8c08fa199a316942f373b968d22 Closes-Bug: #1517271

CLI entry point to show how TOSCA Parser can be used programmatically
|
|
|
|
This is a basic command line 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,
|
|
#tosca-parser --template-file=<path to the YAML template>
|
|
#tosca-parser --template-file=<path to the CSAR zip file>
|
|
#tosca-parser --template-file=<URL to the template or CSAR>
|
|
|
|
e.g.
|
|
#tosca-parser
|
|
--template-file=toscaparser/tests/data/tosca_helloworld.yaml
|
|
#tosca-parser
|
|
--template-file=toscaparser/tests/data/CSAR/csar_hello_world.zip
