Flagging imported definitions

Misc fixes

v0.0.10

Fix imports above namespace in "namespace_first" rule. Few other misc…

Miscellaneous fixes

• Added rules that check:
  • Only one namespace is defined and it must be at the top of the WIDL document
  • Only one interface can be defined
  • Allow ALIAS as a directive location
• Fixed enumeration parsing of optional display string.
• Added Annotated interface for use in the code generator.

Alias types

Alias syntax:

alias UUID = bytes

Aliases are similar to (and inspired by) Scalar types from GraphQL, but the difference is that Aliases target a primitive or user-defined type. The intention is mainly to help the a code generation module redirect an aliased type to an alternate type that is treated a specific way. For example, the alias of UUID = bytes might indicate that a byte array that should be treated as a UUID (16 bytes). The code generator would select the ideal internal type for its targeted programming language.

Added WIDL module template

You can now use the CLI to bootstrap a codegen plugin.

wapc new @wapc/widl/module my_module

cd my_module

npm install
npm run build

Misc fixes

• Fixed required annotation error message
• Making a return type optional (assumes void) and fixing validation rule for void returns
• Disable camel case directive name rule
• Fix descriptions over namespaces, imports, directives, interfaces and roles
• Make parameters parenthesis options for directive definitions
• Added parseType
• Switch on kind improvement
• Added annotation callback
• novisit annotation for types and enums
• Operation returns void validation fix
• Required field from type in valid annotation check

Misc refactoring, imports, directive "requires", and validation

Add a few language features:

• Imports - includes types and directives from a resolver function. In practice, this will load from ~/.wapc/definitions which is installed to wapc install (upcoming PR in the CLI)
• Directive requires @other on TYPE | etc. syntax to target what other directives must exist in relation to it (validation forthcoming)

Refactored:

• Added validate function that takes in configuration rules (which as visitors in rules)
• Kinds are now an enum - no more instanceof
• Organization of classes into definitions, nodes, types & values
• More visitor hooks

Add isKind helper method to the AST
