harmony_composer

harmony_composer is a command-line utility for compiling and bootstrapping deployments for the Harmony orchestration framework.

It's designed to simplify the build process by either compiling a Harmony project found in a local harmony directory or by bootstrapping a new deployment through auto-detection of the current project type.

⚡ Quick Install & Run (Linux x86-64)

You can download and run the latest snapshot build with a single command. This will place the binary in ~/.local/bin, which should be in your PATH on most modern Linux distributions.

mkdir -p ~/.local/bin && \
curl -L https://git.nationtech.io/NationTech/harmony/releases/download/snapshot-latest/harmony_composer \
  -o ~/.local/bin/harmony_composer && \
chmod +x ~/.local/bin/harmony_composer && \
alias hc=~/.local/bin/harmony_composer && \
echo "\n\nharmony_composer installed successfully\!\n\nUse \`hc\` to run it.\n\nNote : this hc alias only works for the current shell session. Add 'alias hc=~/.local/bin/harmony_composer' to your '~/.bashrc' or '~/.zshrc' file to make it permanently available to your user."

Then you can start using it with either :

• harmony_composer if ~/.local/bin is in you $PATH
• hc alias set up in your current shell session.
  • If you want to make the hc command always available, add alias hc=~/.local/bin/harmony_composer to your shell profile. Usually ~/.bashrc for bash, ~/.zshrc for zsh.

⚠️ Warning: Unstable Builds The snapshot-latest tag points to the latest build from the master branch. It is unstable, unsupported, and intended only for early testing of new features. Please do not use it in production environments.

⚙️ How It Works

harmony_composer requires either cargo or docker to be available on your system to compile the Harmony project.

• If cargo is found: It will be used to compile the project locally.
• If cargo is not found: It will automatically download and run the harmony_composer Docker image. This image is a self-contained build environment with the required Cargo binary and build targets for both Linux and Windows.
• If both cargo and docker are unavailable, harmony_composer will fail. Please install one of them.

📖 Basic Usage

Here are some common commands:

# Compile the repo's Harmony module
harmony_composer compile

# Run check script on the project
harmony_composer check

# Run the repo's entire harmony deployment sequence
harmony_composer deploy

# Run the full check, compile, and deploy pipeline
harmony_composer all

For a full list of commands and their options, run:

harmony_composer --help

🏗️ Supported Architectures

The build system currently supports compiling for:

x86_64-unknown-linux-gnu
x86_64-pc-windows-gnu

More target architectures are planned. If your platform is not yet supported, please open a feature request in the main repository.
