From 84726dad9894e888b211adc6d63c9e287026030b Mon Sep 17 00:00:00 2001 From: scawful Date: Mon, 6 Oct 2025 13:07:49 -0400 Subject: [PATCH] feat: Enhance Emulator with State Management and Command-Line Options - Added command-line flags for ROM loading, GUI toggling, state loading, and dumping, improving emulator flexibility. - Implemented state management in the Snes class with loadState and saveState methods for saving and restoring emulator state. - Updated the main emulator loop to handle frame counting and logging, providing better insights during execution. - Refactored CMake configuration to streamline build options for the emulator application. --- src/CMakeLists.txt | 39 +++++++++++---- src/app/emu/emu.cc | 69 +++++++++++++++++++++++++-- src/app/emu/snes.cc | 114 ++++++++++++++++++++++++++++++++++++++------ src/app/emu/snes.h | 3 ++ 4 files changed, 200 insertions(+), 25 deletions(-) diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt index c0cf634e..e6618f62 100644 --- a/src/CMakeLists.txt +++ b/src/CMakeLists.txt @@ -334,7 +334,7 @@ if (YAZE_BUILD_APP) endif() endif() -if(YAZE_BUILD_EMU AND NOT YAZE_WITH_GRPC) +if(YAZE_BUILD_EMU) if (NOT YAZE_MINIMAL_BUILD AND APPLE) add_executable( yaze_emu @@ -354,6 +354,7 @@ if(YAZE_BUILD_EMU AND NOT YAZE_WITH_GRPC) cli/service/rom/rom_sandbox_manager.cc ) target_link_libraries(yaze_emu PUBLIC ${COCOA_LIBRARY}) + target_compile_definitions(yaze_emu PRIVATE IMGUI_DEFINE_MATH_OPERATORS) elseif(NOT YAZE_MINIMAL_BUILD) add_executable( yaze_emu @@ -383,27 +384,43 @@ if(YAZE_BUILD_EMU AND NOT YAZE_WITH_GRPC) ${CMAKE_SOURCE_DIR}/incl/ ${CMAKE_SOURCE_DIR}/src/ ${CMAKE_SOURCE_DIR}/src/lib/imgui_test_engine + ${CMAKE_SOURCE_DIR}/third_party/httplib ${PNG_INCLUDE_DIRS} ${SDL2_INCLUDE_DIR} ${CMAKE_CURRENT_BINARY_DIR} ${PROJECT_BINARY_DIR} ) - target_link_libraries( - yaze_emu PUBLIC +target_link_libraries(yaze_emu PUBLIC ${ABSL_TARGETS} ${SDL_TARGETS} ${PNG_LIBRARIES} ${CMAKE_DL_LIBS} ImGui asar-static + nlohmann_json::nlohmann_json + yaze_agent + yaze_editor + yaze_zelda3 + yaze_gui + yaze_gfx + yaze_core_lib + yaze_util + yaze_test_support ) - if(YAZE_ENABLE_UI_TESTS) - target_link_libraries(yaze_emu PUBLIC ImGuiTestEngine) - target_compile_definitions(yaze_emu PRIVATE YAZE_ENABLE_IMGUI_TEST_ENGINE=1) - else() - target_compile_definitions(yaze_emu PRIVATE YAZE_ENABLE_IMGUI_TEST_ENGINE=0) + if(YAZE_WITH_GRPC) + target_compile_definitions(yaze_emu PRIVATE YAZE_WITH_JSON) + target_include_directories(yaze_emu PRIVATE ${CMAKE_SOURCE_DIR}/third_party/json/include) + + target_add_protobuf(yaze_emu + ${CMAKE_SOURCE_DIR}/src/protos/imgui_test_harness.proto + ${CMAKE_SOURCE_DIR}/src/protos/canvas_automation.proto) + + target_link_libraries(yaze_emu PRIVATE + grpc++ + grpc++_reflection + libprotobuf) endif() endif() endif() @@ -1040,6 +1057,12 @@ source_group("CLI" FILES cli/cli_main.cc cli/tui/tui.cc cli/tui/tui.h + cli/tui/unified_layout.cc + cli/tui/unified_layout.h + cli/tui/enhanced_chat_component.cc + cli/tui/enhanced_chat_component.h + cli/tui/enhanced_status_panel.cc + cli/tui/enhanced_status_panel.h cli/cli.cc cli/cli.h ) diff --git a/src/app/emu/emu.cc b/src/app/emu/emu.cc index b9dc239f..42e66448 100644 --- a/src/app/emu/emu.cc +++ b/src/app/emu/emu.cc @@ -10,10 +10,20 @@ #include "absl/debugging/failure_signal_handler.h" #include "absl/debugging/symbolize.h" -#include "absl/status/status.h" -#include "util/sdl_deleter.h" +#include "absl/flags/flag.h" +#include "absl/flags/parse.h" #include "app/emu/snes.h" #include "app/rom.h" +#include "util/sdl_deleter.h" + +ABSL_FLAG(std::string, rom, "", "Path to the ROM file to load.");
