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.
This initial commit sets up the basic structure for a Rust
implementation of the Lox interpreter, including:
- Lexer for tokenizing source code - Parser for building AST - Basic
interpreter functionality - Environment for variable storage
The core components include source tracking, error handling, and basic
expression evaluation.
