ast-generator - npm Package Versions

[0.6.0] - 2025-01-31

• Breaking Put settings in a new settings block, i.e.

  settings {
    output = "../gen-here-plz.ts"
  }
  

  instead of the old (no longer supported):

  set output "../gen-here-plz.ts"
  

• Add understood settings discriminator, and output for now. More settings will be added later.
• Generate to generated-ast.ts by default, but allow specifying it through output = "../somewhere-else.ts"
• No longer support passing output file as a CLI argument

[0.5.0] - 2025-01-30

• Breaking Node unions no longer have to be written using @MyUnion syntax. This is now "just" MyUnion. The definition itself determines whether it's a union or a basic node.
• Added support for literal types, e.g., op: ">" | "<" | ">=" | "<=" (previously the closest best thing was op: string).

[0.4.0] - 2025-01-29

• Every Node now has generated .children and .descendants iterator properties, which enable you to iterate over all of its children in a type-safe manner.
• Add support for addition of externally defined semantic properties/methods.
• Add support for changing discriminator field, using set discriminator "_kind" in the grammar.
• Change default discriminator field to type.
• Breaking No longer generates visit() method. You can now use the built-in .children and .descendants properties (available on every Node) or defineMethod() to implement your own custom visitors.
