onflow/cadence v0.8.0

on GitHub

This release focuses on improvements, bug fixes, and bringing the documentation up-to-date.

🛠 Improvements

• Improved support on Windows: Treat carriage returns as space (#304)

• Improved JSON marshalling for more AST elements (#292, #286)

• Recursively check if assignment target expression is valid, don't copy returned values (#288)

• Consider existing prefix when suggesting completion items (#285)

• Include available declarations in "not declared" error (#280)

• Enforce the requirement for types to be storable in more places:

  • Transaction/script parameter types (#305)
  • Script return type (#291)
  • Arguments passed to the account load and store functions (#251)

  Previously, using non-storable failed at run-time, now the programs are rejected statically.

⭐ Features

• Add a version constant (#289)
• Language Server: Include error notes as related information in diagnostic (#276)

🐞 Bug Fixes

• Don't return an error when a location type is not supported (#290)
• Handle incomplete types in checker (#284)
• Fix the suggestion in the error when an interface is used as a type (#281)

📖 Documentation

• Brought the documentation up-to-date, include all new language features and API changes (#275, #277, #279)

💥 Breaking Changes

• Arguments passed to cadence.Value#WithType are now typed as pointers (*cadence.Type) rather than values (cadence.Type)

  Example:

  myEventType := cadence.EventType{...})
  
  // this 👇 
  myEvent := cadence.NewEvent(...).WithType(myEventType)
  
  // changes to this 👇 
  myEvent := cadence.NewEvent(...).WithType(&myEventType)
