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.

The additive shared configuration libraries provide typed TOML, YAML, JSON/JSON5 documents, pure source resolution, named profiles, validation and winning origins without constructing the CLI. Morphir.Configuration.IO reads explicit files or supplied text and exposes bounded project/workspace discovery through native and in-memory trees. See the discovery guide for ProjectSystem.Discover, per-root/member ProjectSystem.Load, membership/selection, host boundaries and explicitly authorized machine sources. Existing Git-first artifact discovery, cache-only tooling and CI overlays keep their compatibility behavior. Shared inspection APIs and morphir config get/list/show/path/explain expose typed values, source reports, scoped queries and redacted explanations. The optional Microsoft adapter projects one resolved document with explicit/source-generated Options binding. See the CLI reference for read controls, JSON schema and exit codes. Shared editing services and morphir config set/unset provide typed, scoped TOML previews and writes, source-preserving changes, optimistic conflicts and explicit recovery ownership. Shared classic project migration and morphir project migrate provide loss-checked previews and guarded TOML adoption while retaining classic bytes. Shared workspace migration adds bounded inventory, verified membership and recoverable batch application through morphir workspace migrate [directory]. See the reader profile for syntax and provenance.

Get started

Install morphirup, the Morphir toolchain manager. It is one file and needs nothing else installed.

# macOS (Apple silicon) and Linux (x64, ARM64)
curl -fsSL https://raw.githubusercontent.com/finos/morphir-dotnet/main/scripts/install-morphirup.sh | sh

# Windows (x64, ARM64), in PowerShell
irm https://raw.githubusercontent.com/finos/morphir-dotnet/main/scripts/install-morphirup.ps1 | iex

# Or with mise
mise use -g 'github:finos/morphir-dotnet[matching=morphirup,version_prefix=v,prerelease=true]'

The script installs the newest release and verifies the download first. Open a new terminal and run morphirup --version; it prints the version you installed.

Next, build your first model. The installation guide covers script options, a given release, manual download and the standalone morphir CLI. If something goes wrong, see Troubleshooting.

SDK libraries

Morphir.SDK.CSharp is an independent net11.0 and net10.0 runtime package with immutable C#/.NET public types. See the C# SDK guide for its bounded operation contract and package usage.

The in-memory C# generator lowers typed classic/v4 libraries with explicit numeric C# 14/15 profiles, immutable values, executable functions/patterns/record operations and public SDK bindings. Original business fixtures and the bounded modern package-host/trimming checks are verified under #474. Implementation #478 landed. The main specification and archived acceptance evidence landed in archive follow-up #480. Coordinator cleanup remains pending.

Generate C# through the existing CLI, with numeric profiles and a validated optional namespace:

morphir generate --input model.json --target csharp --output generated --option language-version=14 --option namespace=Example.Generated --json

The C# walkthrough builds and runs a fresh consumer against the immutable runtime. CLI implementation #482 landed; its main specification and archived evidence are synchronized in this follow-up. Archive PR landing and root-verified cleanup remain pending.

Build from source and other installs

Building from source

The repository builds with the .NET 11 SDK and C# 15. Applications, .NET tools and tests target net11.0. Packable libraries target net11.0 and net10.0 (.NET 10 LTS), so .NET 10 applications can use them. .NET 8 and .NET 9 reached the end of support on 2026-11-10, so .NET 10 is the lowest target. MSBuild tasks and Myriad plugins target net10.0, so the .NET 10 SDK can load them. The netstandard2.0 attribute packages keep that target. The properties MorphirCurrentTargetFramework, MorphirLibraryTargetFrameworks and MorphirHostedTargetFramework in Directory.Build.props set these targets.

Install the SDK pinned in global.json, or use mise install to install the tools in mise.toml. CI uses the same SDK pin.

VS Code users can run Dev Containers: Reopen in Container to use the Microsoft .NET SDK image in .devcontainer/Dockerfile. The SDK includes the C# and F# compilers. Renovate groups the container, global.json, and mise SDK updates together and keeps them on the .NET 11 SDK. Moving to the next SDK major version requires an explicit baseline update.

./build.sh --target Test
./build.sh --target PackAll
./build.sh --target TestBuild

To compile classic Morphir model JSON into F#, see the Myriad getting-started article, plugin reference, and car rental tutorial. The runnable example covers inventory, reservation, pickup, return and billing with one generated F# file per module.

Other ways to install the standalone morphir CLI

To install with morphirup, see Get started. These routes install the morphir command line itself:

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 --global Morphir.Tool --prerelease

Verify Installation:

morphir --version          # native executable
dotnet-morphir --version   # .NET tool

Compile F# to Morphir IR: follow the five-minute Compile F# guide.

Building

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

Requirements

• .NET SDK 11.0.100 or a later patch in the same feature band, as specified in global.json

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.

Build system

The build runs on Fallout 10.5.0, the successor to Nuke. ./build.sh, build.ps1, and build.cmd are the entry points. Target names are unchanged from the earlier Just-to-Nuke move, which is recorded in NUKE_MIGRATION.md.

Developing

The shared .NET SDK contract freezes the bounded operation signatures, scalar limits and independent expectations used by both SDK deliveries. See the fixture guide for the build command, schema and provenance. After building its test project, run the offline validator with:

dotnet exec tests/Morphir.SDK.Conformance.Tests/bin/Debug/net11.0/Morphir.SDK.Conformance.Tests.dll --maximum-parallel-tests 2

F# runtime consumers use Morphir.SDK.FSharp. Its namespace and runtime assembly remain Morphir.SDK, so existing generated source and runtime type identities remain valid. The legacy Morphir.SDK package depends on the canonical package and ships no runtime assembly. See the F# runtime migration guide for dependency selection and covered behavior corrections.

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 the direct C# file execution of the .NET SDK. These scripts are located in the scripts/ directory:

• 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, pack-tool-platform.cs, publish-single-file.cs and publish-single-file-untrimmed.cs scripts have been removed. Use the Nuke build targets (PackTool, PublishTool, PackRelease, PublishSingleFile, PublishSingleFileUntrimmed) 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 Release Profiles

The four .NET deployment offerings each have a named release profile. PackRelease publishes one profile for one platform and packs it into an archive named morphir-dotnet-<release>-<deployment>-<rid>.<zip|tar.gz> (zip on Windows, tar.gz elsewhere, files at the archive root), or for dotnet-tool the Morphir.Tool.<release>.nupkg package. The release comes from CHANGELOG.md. Output goes to artifacts/release/; the publish folders are in artifacts/release/publish/<deployment>/<rid>/.

# Native AOT morphir (src/Morphir). Build on the operating system of the RID.
./build.sh --target PackRelease --deployment native-aot --rid linux-x64
build.cmd --target PackRelease --deployment native-aot --rid win-arm64

# Managed morphir with the in-process F# frontend (src/Morphir.Managed), untrimmed folder archives
./build.sh --target PackRelease --deployment self-contained --rid osx-arm64
./build.sh --target PackRelease --deployment framework-dependent --rid linux-arm64

# The Morphir.Tool package (dotnet-morphir). Portable, so no --rid.
./build.sh --target PackRelease --deployment dotnet-tool

# Publish only, without the archive
./build.sh --target PublishRelease --deployment self-contained --rid win-x64

Platforms: win-x64, win-arm64, osx-x64, osx-arm64, linux-x64, linux-arm64. Any other RID is refused. Beside each archive, <archive>.build-launch.json records its launch path, execution mode, layout (single-file, folder or tool-package), bundled runtime, required runtime or SDK, F# frontend, prerequisites and SHA-256. The operating-system prerequisites are not declared yet; qualifying the artifact on each platform establishes them. It is a build output, not a public contract. PackRelease fails when the publish folder contradicts it, for example a framework-dependent folder that carries coreclr. Building a profile does not qualify a platform: no platform is release-qualified yet. Checking the release profiles from packaged artifacts runs the E2E suite against the packaged archives and lists what has been run on each platform; nothing is qualified by it. PackRelease also writes <archive>.build-contents.json and artifacts/release/size-report.md, which list every file each artifact contains with its size.

The same publish folder always gives the same archive bytes. A publish for one RID writes its NuGet lock files under obj/publish-lock/<rid>/, so it leaves the committed packages.lock.json files alone. To check, run git status --short before and after PackRelease: it should list nothing new outside artifacts/, which is ignored.

On Windows, the Native AOT link needs the Visual Studio C++ build tools for the target architecture, and the ILCompiler targets call vswhere.exe. If the link fails with "'vswhere.exe' is not recognized", put %ProgramFiles(x86)%\Microsoft Visual Studio\Installer on PATH in that shell.

Building Executables

These targets keep the layouts that the workflows and E2E tests use. PublishSingleFile builds the legacy release asset that releases ship as morphir-<rid>[.exe] and morphir-<rid>-v<version>.tar.gz.

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

# 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 --single-file-dir ./bin
build.cmd --target PublishSingleFile --rid linux-x64 --configuration Debug --single-file-dir ./bin

Building the Dotnet Tool

# Pack the Morphir CLI as a dotnet tool
./build.sh --target PackTool                                  # Unix/macOS
build.cmd --target PackTool                                   # Windows

# With version and output directory
./build.sh --target PackTool --version 2.0.0 --output-dir ./packages
build.cmd --target PackTool --version 2.0.0 --output-dir ./packages

Testing

# Run unit tests
./build.sh --target Test                                      # Unix/macOS
build.cmd --target Test                                       # Windows

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

# Build the black-box test project for the published targets
./build.sh --target BuildE2ETests
build.cmd --target BuildE2ETests

# Run end-to-end tests
./build.sh --target TestE2E                                   # Unix/macOS
build.cmd --target TestE2E                                    # Windows

# Run the black-box tests on one target (a value of MORPHIR_TEST_TARGET, or tool, all or offerings)
./build.sh --target TestE2E --executable-type trimmed
build.cmd --target TestE2E --executable-type trimmed

SDK runtime delivery and archival evidence is recorded in the runtime delivery record. The canonical C# runtime spec, F# package spec, and stable C# API handoff describe the landed runtimes. SDK archive #472 landed; source SDK worktrees and their owned artifacts were removed. Empty shared archive directory cleanup remains pending with the recorded permission/policy limitations.

OpenSpec change proposals

The extension installation library documents the implemented distribution parsers, platform mappings and MEP eligibility checks, along with the remaining installer work tracked by #558. Extension installation commands are not implemented yet.

The Morphir Compatibility Kit seed contains portable F# frontend cases, a closed step vocabulary and the deterministic library runner. Its reader/runner tests and Native AOT smoke check are independent of the production F# frontend, which is still being implemented.

This repository uses the shared html-design OpenSpec workflow. New proposals produce capability specs, a standalone design.html, and implementation tasks. See the OpenSpec guide for setup, verification and updates.
