Extending Asset with Contract or Clause causes Archive error #791
Description
Bug Report 🐛
The cicero archive command requires a valid package.json file which must contain either:
"accordproject": {
"template": "clause",
"cicero": "^0.24.0",
"runtime": "ergo"
},
-- OR --
"accordproject": {
"template": "contract",
"cicero": "^0.24.0",
"runtime": "ergo"
},
Note: Without this object in the package.json file, the cicero archive command throws the following expected error:
ERROR: /Users/martin/hello-world is not a valid cicero template. Make sure that package.json exists and that it has a cicero entry.
Assume you have the following grammar.tem.md file:
namespace hello@1.0.0
@template
concept HelloWorld {
o String name
}
Attempting to execute cicero archive as a Clause template with this grammar.tem.md will result in the error:
ERROR: Failed to find an asset that extends org.accordproject.contract.Clause. The model for the template must contain a single asset that extends org.accordproject.contract.Clause.
Attempting to execute cicero archive as a Contract template with this grammar.tem.md will result in the error:
ERROR: Failed to find an asset that extends org.accordproject.contract.Contract. The model for the template must contain a single asset that extends org.accordproject.contract.Contract.
Attempted Fix 1:
Attempt to fix the issue by adding extends Contract or extends Clause to concept, like so:
namespace hello@1.0.0
@template
concept HelloWorld extends Contract {
o String name
}
This results in the error:
ERROR: Could not find super type Contract File '/Users/martin/hello-world/model/model.cto': line 3 column 1, to line 6 column 2.
-- OR --
namespace hello@1.0.0
@template
concept HelloWorld extends Clause {
o String name
}
This results in the error:
ERROR: Could not find super type Clause File '/Users/martin/hello-world/model/model.cto': line 3 column 1, to line 6 column 2.
Attempted Fix 2:
Add contract import to model.cto like so:
namespace hello@1.0.0
import org.accordproject.contract@0.2.0.Contract from https://models.accordproject.org/accordproject/contract@0.2.0.cto
@template
concept HelloWorld extends Contract {
o String name
}
This results in the error:
ERROR: ConceptDeclaration (HelloWorld) cannot extend AssetDeclaration (Contract) File '/Users/martin/hello-world/model/model.cto': line 5 column 1, to line 8 column 2.
Context (Environment)
- Cicero Version: 0.24.1-20230722135139
- Concerto Version: 3.12.0
Summary
It seems that cicero archive requires an asset to extend either Contract or Clause but the concerto syntax no longer considers this as valid syntax.
Note: Also tried concerto compile --model ./hello-world/model/model.cto --target Rust and got same error.
