It supports:

• string, list, and hash commands
• RESP command parsing
• multi-client TCP server
• periodic and shutdown persistence (dump.reddish)

Build

Recommended (MSVC preset)

cmake --preset msvc-release
cmake --build --preset build-release

Binary:

• build/msvc-release/output/reddish.exe

Generic CMake

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build

Binary:

• build/output/reddish
• build/output/reddish.exe

Run

./build/output/reddish

Or with custom port:

./build/output/reddish 6389

Documentation

Generate API docs:

cmake --preset msvc-release
cmake --build build/msvc-release --target docs

Output:

• docs/html/index.html

Theme:

• doxygen-awesome-css (fetched by CMake during configure)

Project layout

• src/NetworkApi.hpp / src/NetworkApi.cpp: cross-platform socket helpers
• src/Server.hpp / src/Server.cpp: TCP accept loop and client thread handling
• src/CommandHandler.hpp / src/CommandHandler.cpp: command parsing and dispatch
• src/Database.hpp / src/Database.cpp: in-memory storage and persistence
• src/main.cpp: startup and background persistence thread

Notes

• Build system is CMake-based; use CMakePresets.json for local setup.
• Threads::Threads is intentionally linked for portable thread support.
