- Add distance-based get_at on EnvironmentStack
- Add distance-based assign_at on EnvironmentStack
- Introduce ErrorSink to accumulate diagnostics across passes
- Implement Resolver with a ScopeStack and per-node distance map
- Extend interpreter to store locals distances for runtime lookup
- Add tests for resolution behavior and error accumulation
Add static variable resolution with scope tracking
for AST return value tracking
The changes introduce support for tracking return values and labels
across AST nodes. The key changes include:
- Adding ReturnValue type to BaseValue - Adding return_type field to
LoxFunction - Adding label field to Block statements - Creating
middleend crawler module for AST traversal Add return value types to AST
This accurately captures both changes: adding `.idea/` to gitignore and
adding return value types to the AST structure. The changes include
adding return value fields to statement nodes and adjusting the
interpreter logic accordingly.
The commit changes the interpreter and related code to use the new
`BaeValue` and `Number` types, moving away from direct floats. The main
changes include:
- Replace LiteralValue with BaeValue across the codebase - Add Number
enum for type-safe numeric values - Move AST definitions to common
module - Update operators to handle new numeric types - Add 'is' token
type and parser support Switch to common base_value library for value
types
This commit represents a significant refactoring to switch the
interpreter to use a new shared base value type system. The main changes
include:
1. Move value types to a new common/base_value.rs module 2. Add richer
numeric type support with promotion rules 3. Update interpreter to use
new BaseValue enum 4. Move AST types to common module for sharing 5.
Consolidate value operations like Add, Sub etc 6. Add proper test
coverage for numeric operations
The commit improves type safety and adds more robust numeric handling
while keeping the interpreter's core logic clean.
