Morphir

Morphir is a library of tools that works to capture business logic as data.

For the first time, business logic can be shared, stored, translated and visualised, all with the reliability of standardisation ensured in the Morphir framework.

What is it?

A set of tools for integrating technologies. Morphir is composed of a library of tools that facilitate the digitisation of business logic into multiple different languages & platforms. The Morphir framework is unique too in that facilities elements of automation and conversion that were previously unavailable in the field of finance-tech.

Why is it important?

Makes business logic portable. Business logic digitised provides distinct advantages: capacity for movement across departments and fields & the ability to be converted to new languages and applications.

How does it work?

Defines a standard format for storing and sharing business logic. A clear set of standards and format is in-place from the input/output, allowing for coherent structure.

What are the benefits?

✔️ Eliminates technical debt risk

Refactoring code libraries is often a harmful and time-sensitive issue for businesses, Morphir ensure the standards introduced from input eliminate delays at deployment.

✔️ Increases agility

Adaptability and usability are key concepts of the Morphir framework, business logic can now move with the code, be easily understood and adopted, in an ever-developing eco-system.

✔️ Ensures correctness

Certifying that specified functions behave as intended from input to output is assured through the Morphir library / tool chain.

✔️ Disseminates information through automation

Morphir’s automated processing helps disseminate information which otherwise may not be understood or shared at all, a useful tool when brining elements of business logic to conversation outside of its immediate audience (i.e developers).

Morphir .NET

Provides tooling for the Morphir ecosystem and .NET libraries that can be used to help you work with Morphir.

Getting Started

Quick Start

Install Morphir using one of the following methods:

Using proto (Recommended for multi-language toolchains):

# Install proto (if not already installed)
curl -fsSL https://moonrepo.dev/install/proto.sh | bash # Linux/macOS
# or: irm https://moonrepo.dev/install/proto.ps1 | iex # Windows

# Add Morphir plugin and install
proto plugin add morphir "source:https://github.com/finos/morphir-dotnet/releases/latest/download/morphir_plugin.wasm"
proto install morphir

Using Platform-Specific Install Scripts:

# Linux
curl -fsSL https://raw.githubusercontent.com/finos/morphir-dotnet/main/scripts/install-linux.sh | bash

# macOS
curl -fsSL https://raw.githubusercontent.com/finos/morphir-dotnet/main/scripts/install-macos.sh | bash

# Windows (PowerShell)
irm https://raw.githubusercontent.com/finos/morphir-dotnet/main/scripts/install-windows.ps1 | iex

Using .NET Tool (requires .NET SDK):

dotnet tool install -g Morphir

Verify Installation:

morphir --version

For detailed installation instructions and troubleshooting, see the Installation Guide.

Building

This project uses Nuke for build orchestration, providing a strongly-typed, cross-platform build system written in C#.

Requirements

• .NET SDK 10.0 or higher

Basic Commands

# First-time setup: Restore tools and dependencies
dotnet tool restore
./build.sh --target Restore

# Build the solution (default target)
./build.sh

# Run tests
./build.sh --target Test

# Run linting/formatting checks
./build.sh --target Lint

# Format code
./build.sh --target Format

# Run full CI pipeline (restore, build, test, lint)
./build.sh --target CI

# Show all available targets
./build.sh --help

Windows users: Use build.cmd or build.ps1 instead of ./build.sh

Configuration

You can set the build configuration using the --configuration parameter:

# Build in Debug mode
./build.sh --configuration Debug

# Run tests in Debug mode
./build.sh --target Test --configuration Debug

By default, commands use Release configuration.

Migration from Just

This project was recently migrated from Just to Nuke. See for the complete migration guide and command mappings. The old justfile is preserved for reference.

Development Workflow

1. Restore dependencies:

   ./build.sh --target Restore
   

2. Build the solution:

   ./build.sh --target Compile
   

3. Run tests:

   ./build.sh --target Test
   

4. Check code formatting:

   ./build.sh --target Lint
   

5. Format code (if needed):

   # Unix/macOS
   ./build.sh --target Format
   
   # Windows
   build.cmd --target Format
   # or
   ./build.ps1 --target Format
   

Scripts

The project uses C# scripts (.cs files) for build automation, leveraging .NET 10's direct C# file execution. These scripts are located in the scripts/ directory:

• publish-single-file.cs - Publishes trimmed single-file executables
• publish-single-file-untrimmed.cs - Publishes untrimmed single-file executables
• run-tests.cs - Runs unit tests
• run-e2e-tests.cs - Runs end-to-end tests
• generate-wolverine-code.cs - Generates Wolverine code

Note: The deprecated build-tool-dll.cs and pack-tool-platform.cs scripts have been removed. Use the Nuke build targets (PackTool, PublishTool) instead.

Build Commands

All Nuke build commands support both Unix/macOS (./build.sh) and Windows (build.cmd or ./build.ps1) bootstrap scripts. Examples below show both formats.

Building Libraries

# Unix/macOS: Pack library projects as NuGet packages
./build.sh --target PackLibs

# Windows
build.cmd --target PackLibs
# or
./build.ps1 --target PackLibs

# Pack all projects (libraries and tool)
./build.sh --target PackAll # Unix/macOS
build.cmd --target PackAll # Windows

# Specify configuration and version
./build.sh --target PackLibs --configuration Debug --version 1.2.3
build.cmd --target PackLibs --configuration Debug --version 1.2.3

# Custom output directory
./build.sh --target PackLibs --output-dir ./my-packages
build.cmd --target PackLibs --output-dir ./my-packages

Building Executables

# Build a trimmed single-file executable for a specific platform
./build.sh --target PublishSingleFile --rid linux-x64 # Unix/macOS

# Build an AOT (ahead-of-time compiled) executable
./build.sh --target PublishExecutable --rid linux-x64
build.cmd --target PublishExecutable --rid linux-x64

# Build an untrimmed executable (larger, better for debugging)
./build.sh --target PublishSingleFileUntrimmed --rid win-x64
build.cmd --target PublishSingleFileUntrimmed --rid win-x64

# Common RIDs: linux-x64, linux-arm64, win-x64, osx-x64, osx-arm64

# With custom configuration and output directory
./build.sh --target PublishSingleFile --rid linux-x64 --configuration Debug --output-dir ./bin
