Technology Stack

Build System

• CMake 3.16+ with Ninja generator for C++ projects
• Docker containerized builds using gitea.jde.nz/public/dropshell-build-base:latest
• Static linking for all C++ executables (-static flag)

Languages & Standards

• C++23 standard for all C++ projects
• Bash for shell scripts and simple tools
• Shell scripts follow set -euo pipefail pattern

Dependencies

• nlohmann_json for JSON handling in C++ projects
• CPR (static) for HTTP requests in getpkg
• Custom modules in /usr/local/share/cmake/Modules

Common Build Patterns

C++ Projects (CMake)

# Standard build command
cmake -G Ninja -S . -B ./build -DCMAKE_BUILD_TYPE=Debug -DPROJECT_NAME=<project>
cmake --build ./build

Docker Build (for C++ tools)

# Uses Dockerfile.dropshell-build pattern
docker build -t <project>-build -f Dockerfile.dropshell-build --build-arg PROJECT=<project> --output ./output .

Shell Tools

• No build step required
• Executable shell scripts with proper shebang
• Use chmod +x for permissions

Common Commands

Build

./build.sh          # Build individual project
./buildtestpublish_all.sh  # Build all projects

Test

./test.sh           # Run tests for individual project

Clean

./clean.sh          # Clean build artifacts

Publish

./publish.sh        # Publish to getpkg.xyz (requires SOS_WRITE_TOKEN)

Version Management

• Automatic timestamp-based versioning: YYYY.MMDD.HHMM
• Version configured via version.hpp.in template files
• Pre-build scripts (cmake_prebuild.sh) for additional setup

Environment Variables

• CMAKE_BUILD_TYPE: Debug/Release (default: Debug)
• SOS_WRITE_TOKEN: Authentication for publishing
• NO_CACHE: Skip Docker cache when set to "true"
• PROJECT: Project name for build scripts
