C-- Release 2.0

• Fixes several major bugs in the previous release with function calls and cin statements.
• Fixes some bugs with the debugger
• Fixes some minor bugs with character printing and negative division.
• Modularizes the semantic analysis and interpretation by creating a class for every AST node which handles compilation and execution with compile and execute methods.
• Rewrites the grammar from bison language to coffeescript language for dynamic generation of rules, reducing redundancies.
• Implements instruction generation in the compilation step, such that an instruction list is produced and the program can be executed step by step.
• Implements variable mapping into a typed address space, which means storing values in a simulated memory implemented with Javascript Typed Arrays. This means every variable has an address associated with it. Fixes inaccurate representation of types: now values overflow as expected for every type.
• Implements const declaration attribute support.
• Implements global variable support.
• Implements variable shadowing support.
• Implements pointer support.
• Implements array support. Currently only literal values are supported as array dimension values on array declarations.
• Implements memory allocation and deallocation with new and delete operators.
• Implements unnamed scopes: (See example).
• Implements a simple Command Line Interface.
• Improves compiler semantic error reporting. Now line/column information is provided, and a specialized description message for each error is provided.
• Implements a testing framework. Every test is C-- program that defines its expected compilation error/success and its input/output pairs and exit status.
• Adds 141 handcrafted compilation and runtime tests.
