* all except pol
* pol and includes under defines
* something weird has happened
* remove own folder from include searchpath
* fixed remaining, adapted include style for external headers
* missing include
* Remove DefaultConstructorFunction
* Modify class parameters; update semantic analysis
- Use ClassDeclarationParameter for class decls vs Identifiers
- Update ScopableName to have equality for constructors and unscoped
function calls
- Update SemanticAnalyzer (self referencing base class, no ctor)
- Update, add tests
* Semantic updates; debug messaging updates
- Ensure base class is constructable
- Various fmt implementations for debugging
* Address self-review comments
* Add Report.debug
* Implement function call scoping
* Implement variable scoping
- Rename `Identifier::scope` to `calling_scope`, and concatenate the identifier scope into `name` if necessary.
- Track current scope in SemanticAnalyzer, similar to UserFunctionVisitor.
- Use current scope in SemanticAnalyzer when visiting identifiers.
* Update grammar for `::identifier` global scoping
* Introduce ScopableName for function resolution
* Address review comments
- Check for display_debugs missing
* Add ScopableName for identifier resolution
* Some cleanup
- Remove `Identifier::calling_scope`, as it is tracked in the semantic
analyzer
- Refactor `ScopeName::exists` to `global` for better clarification of
its use
- Removed `X::maybe_scoped_string/name`
* Address self-review comments
* Rename `Function::module_name` to `scope`
Adds:
- ast/UserFunction AST node for user-defined functions.
- astbuilder/AvailableUserFunction: reference to a parse tree for a user function.
- The AST builder only generates ASTs for user functions that are actually referenced.
- astbuilder/UserFunctionVisitor: visits (builds an AST for) a parse tree for a user function.
- This happens after the .src or .inc file has been otherwise processed, so this class serves to hook up the correct SourceFileIdentifier to the AST.
Adds:
- ast/Argument: AST node for an argument passed to a function.
- ast/FunctionCall: AST node for a function call.
- codegen/ModuleDeclarationRegistrar: The code generator registers module function declarations with this in order to determine module indexes and function indexes for instructions.
- model/FunctionLink: this is a reference either:
- from: a FunctionCall or a FunctionReference
- to: a ModuleFunctionDeclaration or a UserFunction
- optimizer/ReferencedFunctionGatherer: a visitor that determines which module functions and user functions are referenced, by looking at function calls and function references.
Also:
- CodeGenerator registers module functions
- InstructionGenerator generates code for function calls
- InstructionEmitter generates TOK_FUNC instructions
- StoredTokenDecoder decodes TOK_FUNC instructions
After all of this, the compiler can compile print("hello, world");
