Here is a list of all documented files with brief descriptions:

[detail level 123]

include
ast
Ast.h	Defined the AST Node classes (ProgramAST, StructDefAST, FuncDefAST) and a visitor interface for traversing the AST
AstBase.h	Defines the AST Abstract class for printing out AST Nodes
AstDecl.h	Holds declaration for all the AST Nodes
ASTProperties.h
AstWalkers.h
codegen
CodegenUtils.h
CodegenVisitor.h	Defined CgVisitor, which lowers ASTs to LLVM IR
LLVMRes.h	Defined LLVMRes, which encapsulates the state of LLVM (Context, Modules, IRBuilder, PassManagers, JIT) context base information. This resource will be shared across multiple instances within the Compiler
MLIRGen.h
MLIRGenImpl.h
MLIRLowering.h
SammineJIT.h	JIT Compiler based on Kaleidoscope
TypeConverter.h	Defines the TypeConverter, which holds the characistics of converting our AST types into LLVM IR types
compiler
Compiler.h	Define the Compiler staging
lex
Lexer.h	Houses the lexer and the declaration of its method
Token.h	Defines the token structure (TokenType, TokStream, TokenMap)
parser
Parser.h	Defines Parser, which consumes tokens and constructs the AST
semantics
GeneralSemanticsVisitor.h	Defines GeneralSemanticsVisitor, an ASTVisitor that enforces general semantic rules for scoped definitions, detecting duplicates, and ensuring correct return usage in blocks
ScopeGeneratorVisitor.h	Declares ScopeGeneratorVisitor, an ASTVisitor that builds and manages lexical scope by registration and reporting if there's been redefinitions
typecheck
BiTypeChecker.h	Defines the BiTypeCheckerVisitor, consist of the flow for Bi-Directional Type checking, which allows for synthesizing types, validating consistency, and register types
LinearTypeChecker.h	Linear type checker — tracks heap-allocated pointers and enforces they are consumed (freed or moved) exactly once before scope exit
Monomorphizer.h
Types.h	Defines the core Type system for Sammine
util
FileRAII.h	A RAII-wrapper around C++ file type to use in the project for lexer and parser
LexicalContext.h	A simple scoping class, doesn't differentiate between different names, like variable name, func name and all that
Logging.h	LLVM-style debug logging infrastructure
MonomorphizedName.h
QualifiedName.h
Utilities.h	Holds classes and functionalities for dealing with Error handling, source locations caching & indexing
src
ast
Ast.cpp	Implemention of AST Visitor, used for traversing the AST
AstPrinterVisitor.cpp	Implementation for Ast Printer, using a Visitor pattern in order to traverse the AST for better debugging
codegen
CodegenVisitor.cpp	Implementation for CodegenVisitor, it converts the AST Representation into LLVM IR and it also uses a visitor pattern in order to traverse through the parsed AST to emit LLVM IR
SammineJIT.cpp	The Implementation for SammineJIT
TypeConverter.cpp	Implementation for TypeConverter, converting AST Node types into LLVM IR Types
lex
Lexer.cpp	Implementation for scanning and streaming Tokens
semantics
GeneralSemanticsVisitor.cpp	Implementation for GeneralSemanticsVisitor
ScopeGeneratorVisitor.cpp	Implements ScopeGeneratorVisitor, an ASTVisitor that traverses the AST to populate a lexical symbol table
typecheck
BiTypeChecker.cpp	Implementation of BiTypeCheckerVisitor: visit() methods, registration, and helpers. Synthesize methods are in BiTypeCheckerSynthesize.cpp
BiTypeCheckerSynthesize.cpp	All synthesize() methods, call-dispatch helpers, and generic unification/substitution for BiTypeCheckerVisitor
LinearTypeChecker.cpp	Implements linear type checking — enforces that heap-allocated ('ptr<T>) pointers are consumed exactly once before scope exit
Types.cpp	Implements the core Type system for Sammine
Parser.cpp	Implementation for Parser class, it takes in the token stream and converts it into Parsing things suchs as programs, top-level (struct, functions, global variables)
sammine.cpp	The main file to produce an executable that is the sammine compiler
unit-tests
test_lexer.cpp	The unit-test file for all things related to a lexer
test_parser.cpp	The unit-test file for all things related to a parser
