Date: Sun, 30 Nov 2025 15:29:20 +0100 Subject: [PATCH 04/11] chore: Add unit tests for StringScanner, Token, and UTF-8 utilities - Implemented comprehensive unit tests for the StringScanner class, covering various string types including regular, raw, and TeX strings, as well as escape sequences and error handling. - Added unit tests for Token-related functionalities, including SourceLocation, Trivia, TokenSpan, and token management. - Developed unit tests for UTF-8 utility functions, validating character decoding, encoding, and string validity checks. - Updated test cases to ensure robust coverage of edge cases and error scenarios. --- .changes/add-submodule-and-lexer.md | 5 + .gitignore | 8 +- .vscode/settings.json | 28 + CMakeLists.txt | 196 ++++++- Makefile | 28 +- apps/czc/main.cpp

5cf53ffd4bad845b621629edb1c36c0154069c56 From 3a77243f7f335fd34edab84087cd830ceac0843f Mon Sep 17 00:00:00 2001 From: BegoniaHe Date: Sun, 30 Nov 2025 17:23:24 +0100 Subject: [PATCH 05/11] feat: Implement CompilerContext and Driver for improved compilation management - Added CompilerContext to encapsulate global options, output options, and diagnostics. - Introduced Driver class to manage the compilation process, including the execution of the lexer phase. - Enhanced diagnostics system to report errors and warnings during compilation. - Implemented LexerPhase to handle lexical analysis with options for preserving trivia and error reporting. - Updated tests to cover all token types and ensure correct naming in diagnostics. - Refactored existing code for better organization and maintainability. --- ...ver-for-improved-compilation-management.md | 5 + .vscode/settings.json | 14 +- CMakeLists.txt | 3 +- Makefile | 7 +- include/czc/cli/cli.hpp | 51 ++-

<163421589+BegoniaHe@users.noreply.github.com> Date: Thu, 4 Dec 2025 20:37:50 +0100 Subject: [PATCH 06/11] perf: add unit tests for token and UTF-8 utilities - Implement comprehensive unit tests for the token-related functionalities in `token_test.cpp`, covering source locations, trivia, token spans, and various token types. - Introduce unit tests for UTF-8 utility functions in `utf8_test.cpp`, validating character decoding, encoding, validity checks, and character counting. - Ensure tests cover edge cases, including invalid UTF-8 sequences and mixed content strings. ---

and level-to-string conversion in `diagnostic.cpp`. - Implemented ANSI color rendering in `ansi_renderer.cpp` for various diagnostic levels. - Created JSON emitter in `json_emitter.cpp` to output diagnostics in JSON format. - Developed text emitter in `text_emitter.cpp` for plain text output of diagnostics. - Introduced error code registration and lookup in `error_code.cpp`. - Implemented internationalization support in `i18n.cpp` for localized error messages. - Added message handling with Markdown parsing in `message.cpp`. - Created source span abstraction in `span.cpp` for tracking source code locations. - Registered lexer error codes in `lexer_error_codes.cpp` for better error reporting. - Implemented lexer source locator in `lexer_source_locator.cpp` to map errors to source locations. --- .changes/implement-diagnostic-system.md | 5 + CMakeLists.txt | 45 ++- Makefile | 34 +- include/czc/cli/context.hpp | 39 +- include/czc/cli/driver.hpp | 24 +-
