MetaBuilder CLI

This CLI targets MetaBuilder services via HTTP and includes a Lua runtime for executing package scripts. Uses Conan + CMake for dependency management and builds.

Requirements

• Conan 2 (used for dependency resolution)
• CMake 3.27+ (the Conan toolchain generator targets this minimum)
• Ninja (build backend)
• A running MetaBuilder frontend (defaults to http://localhost:3000)

Building

cd frontends/cli
conan install . --output-folder build --build missing
cmake -S . -B build -G Ninja
cmake --build build

Conan provisions these dependencies:

• cpr - HTTP requests
• lua - Lua 5.4 interpreter
• sol2 - C++/Lua binding
• nlohmann_json - JSON handling

Running

The executable looks for METABUILDER_BASE_URL (default http://localhost:3000):

# API commands
./build/bin/metabuilder-cli auth session
./build/bin/metabuilder-cli user list

# Package commands (run from project root)
./build/bin/metabuilder-cli package list
./build/bin/metabuilder-cli package generate my_forum --category social --with-schema --entities Thread,Post
./build/bin/metabuilder-cli package run codegen_studio package_template get_categories

Continuous Integration

Changes under frontends/cli/ trigger .github/workflows/ci/cli.yml, which:

1. Runs Conan to install dependencies
2. Configures and builds with CMake/Ninja
3. Validates that metabuilder-cli --help exits cleanly
