Frosch
Frosch contributed to the OpenTTD/OpenTTD repository by modernizing core systems for string handling, localization, and memory safety, delivering 66 features and 49 bug fixes over three months. He refactored legacy C++ code to use std::string_view and StringBuilder, enabling safer and more efficient UTF-8 processing and reducing memory errors. His work included enhancing NewGRF scripting, improving UI consistency, and optimizing data structures such as ZoomLevel and buffer management with std::byte. By integrating modern C++ practices and robust error handling, Frosch improved code maintainability, internationalization support, and overall runtime reliability, demonstrating depth in C++ development and software engineering.

Apr 1, 2025April 2025 - OpenTTD/OpenTTD monthly summary Key features delivered: - Utf8View-based UTF-8 handling modernization across core text utilities (Textbuf, Utf8StringLength, StringIterator) with const-iteration enabled, and replacement of direct Utf8Encode usages with StringBuilder to reduce copies; IsUtf8Part usage moved to the consuming file. This establishes robust, zero-cost UTF-8 processing and simplifies encoding/decoding paths. - StringBuilder integration and string-building improvements: introduced InPlaceReplacement to couple StringConsumer and StringBuilder on the same buffer and switched translation/encoding/string creation to use StringBuilder, ensuring in-place modifications go through the underlying std::string to minimize copies. - Broad codebase modernization: adoption of std::string_view and std::format; refactoring macros to functions and using constexpr/inline constructs; enum-class refactors and naming consistency; improved error metadata and build/test compatibility; network-wide formatting and cleanup improvements. - NewGRF and scripting enhancements: added road-/tram-/rail-type variable 0x45 for mutual type retrieval; improved parsing and error reporting; expanded NewGRF animation/trigger capabilities with waypoint support; centralization and cleanup of sprite/group resolution paths for better performance. - Infrastructure and quality improvements: move ScriptStorage ctor into source file with smart pointers for script queues; Ini window settings IO updated to use WindowDesc*; callback modernization to std::function (date/screenshot callbacks); improved header include discipline and const-correctness; build-hardening changes (OPTION_DEDICATED OFF / CMAKE_DISABLE_PRECOMPILE_HEADERS=ON). Major bugs fixed: - Char32_t cast fix for UTF-8 helpers: cast to unsigned first to avoid sign-related issues. - ScriptText empty parameters encoding bug fixed. - RTL alignment: numbers no longer left-aligned in RTL contexts; UI alignment corrected. - Czech town names suffix handling cleanup; IsUtf8Part moved to the appropriate file. - StringFilter quotes exclusion: quotes are now excluded from search as intended. - Textbuf input insertion regression fixed; input now inserts correctly again. - VehiclesNearTileXY: distance filtering bug fixed; clamped hash/bucket search areas and added max-distance parameter support. - NewGRF: safe handling for default airports and spritesets; out-of-bounds protection when no spritesets are provided. Overall impact and accomplishments: - Significantly improved UTF-8 correctness, performance, and safety across core text handling, reducing copies and enabling const-iteration. Code modernization reduces technical debt and accelerates future feature work. - Improved stability and reliability through targeted bug fixes and safer string/parsing machinery; enhanced error reporting and debuggability for contributors and users. - Enhanced business value through more robust internationalization support, safer builds, and a maintainable foundation for continued feature work on NewGRF, original English townname logic, and rendering/pipeline improvements. Technologies/skills demonstrated: - Modern C++ practices: std::string_view, std::format, constexpr/inline functions, and std::function; removal of legacy Utf8 utilities; macro-to-function refactors; enum-class usage. - Performance and memory-management discipline: StringBuilder integration, InPlaceReplacement, and in-place edits on underlying strings to minimize copies. - Robust parsing and string handling: StringConsumer-based parsing, safe integer parsing, and improved handling of edge cases in strings and rendering. - Build/configuration hardening and quality: improved header discipline, build flags, and safer defaults for cross-platform builds. - NewGRF feature enablement and protocol cleanup: better type safety via enums, shared random bits, and safer sprite resolution workflows.

Mar 1, 2025OpenTTD/OpenTTD - March 2025 (2025-03) monthly summary focused on strengthening string handling, localization fidelity, and code modernization across NewGRF and translation workflows. Delivered a set of features and fixes that improve localization reliability, runtime performance, and UI consistency, with an emphasis on business value for international players and maintainable code. Key features delivered and major fixes include: - Plural and gender support in NewGRF strings: added plural genders, updated Spanish definitions (es_ES and es_MX), and ensured proper operation within substrings and across related string handling. - NewGRF string handling and interpolation bug fixes: resolved off-by-one parameter issues and ensured all string controls are properly processed during interpolation. - Code quality and API refinements: migrated string handling to std::string/std::string_view, replaced unsafe raw pointers with safer types, improved return/value semantics, and standardized naming for clarity (e.g., RemapNewGRFStringControlCode). - String handling modernization and IO integration: introduced StringConsumer, modernized ByteReader, translation/file parsing using StringConsumer, and integrated StringConsumer across GRF parsing and patch translation paths. - Performance improvements and resource safety: replaced strgen Buffer with StringBuilder, reduced external symbols in strgen, and improved memory usage and type safety throughout string generation and handling. - UX and reliability improvements: fallbacks for ancient NewGRF entries to show filename when name/description are empty; fixed music GUI padding to be symmetric across languages and refined bevel rendering for track names. Overall impact and accomplishments: - Improved localization accuracy and resilience in handling plurals, genders, and long translation strings, boosting international user experience. - Modernized codebase to safer and more maintainable patterns, reducing risk of memory errors and enabling faster feature work. - Enhanced performance and user experience with UI consistency improvements and more reliable string parsing/translation flows. Technologies/skills demonstrated: - C++ modernization: std::string, std::string_view, safe pointers, and modern API surfaces. - String handling architecture: StringConsumer, StringBuilder, ByteReader, and translation/string parsing pipelines. - Refactoring discipline: modularization, symbol minimization, and clearer function naming. - Localization engineering: pluralization/gender rules, es_ES/es_MX updates, and robust substring handling.
