invalid requirement syntax

[glelouet]

requirements in tosca specification is eg

  requirements:
    - database:
        node: my_database
        capability: Endpoint.Database
        relationship: my.types.CustomDbConnection

in this yaml file it is

    requirements:
      - host: tosca.capabilities.Container
        relationship: tosca.relationships.HostedOn

however this syntax is invalid. It should instead be

    requirements:
      - host:
          capability: tosca.capabilities.Container
          relationship: tosca.relationships.HostedOn

Hi Guillaume,

TOSCA grammar has changed on various aspects in the past years and alien4cloud project started based on some early working draft. We are getting closer to full simple profile support keeping retro-compatibility with previous supported grammars.

The current file grammar version is defined by the tosca_definitions_version with is right now alien_dsl_1_2_0.
Since alien4cloud 1.3.0 we support requirement definitions as mentioned in the tosca simple profile in yaml 1.0.0 so we could change the definitions and the version of the definitions. If we do so and even if the content has not changed we would have to release a new version of the normative types as packaged in alien4cloud and decided not do to so in 1.3.0 version.

We will for sure consider that in next versions a4c hopefully shifting the tosca_definitions_version of this document to tosca_simple_yaml_1_0 which is the official one.

You can read more on our support and grammar differences here:
http://alien4cloud.github.io/#/documentation/1.3.0/devops_guide/tosca_grammar/tosca_grammar.html
We updated the documentation recently to state for every element which key name is supported in which dsl version as parsed in alien4cloud and which are not yet supported.

Your issue will remain open until we actually perform the switch.

Thank you very much.

Will you support the shorthand_name ? In Tosca I can write a Node extends Compute, this will be resolved as tosca.nodes.Compute .

I don't know why the shorthand are not present in the tosca normative examples . I am making my own Tosca compiler and I add the corresponding shorthand_name to the definition that have one in the tosca spec.
