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.

morphir-scala

Provides Scala language bindings and JVM based tooling for Morphir.

Installation

You can install the morphir-cli in the following ways:

Using Coursier

cs install --channel https://raw.githubusercontent.com/finos/morphir-scala/main/coursier-channel.json morphir-cli

Then run the CLI:

morphir-cli setup

We also offer an insiders channel that grants access to snapshot releases of the CLI.

cs install --channel https://raw.githubusercontent.com/finos/morphir-scala/main/coursier-channel.json morphir-insiders-cli

Then run the CLI:

morphir-cli setup

NOTE: The main channel above (non-insiders), also offers insiders builds under the name morphir-insiders-cli:

cs install --channel https://raw.githubusercontent.com/finos/morphir-scala/main/coursier-channel.json morphir-insiders-cli

Then run the CLI:

morphir-insiders-cli setup

How to build and test

Morphir-jvm use mill as its build tool.

IntelliJ Setup for Linux

If you are using IntelliJ IDEA to edit morphir-jvm's Scala code, you can create the IntelliJ project files via:

./mill mill.idea.GenIdea/idea

BSP Setup

If you are using Visual Studio Code, IntelliJ, or any of the Editors which support BSP you can also generate BSP config files via:

./mill mill.bsp.BSP/install

You can also try the following to use the mill-contrib-bloop plugin to install and use the Bloop based BSP setup.

NOTE: The recommended BSP based setup for mill is to run: ./mill mill.bsp.BSP/install as mentioned above.

Run Tests

./mill __.test

or in watch mode:

./mill -w __.test

NOTE: When running tests you will want to ensure you have generated the MorphirIR for elm sources if you are running tests for the runtime. A simple way to do this is to use the build.sh helper script an invoke the elm-build option. ./build.sh elm-build

For your convience, you can run the morphir-runtime tests using the following command:

./build.sh test-runtime-jvm

Test Coverage

Before checking test coverage, ensure that all tests have been run using the following command:

./mill __.test

HTML Coverage Report

To generate a human-readable coverage report, run the following command:

./mill scoverage.htmlReportAll

To view the resulting coverage report, open out/scoverage/htmlReportAll.dest/index.html

XML Coverage Report

To generate an XML coverage report, run the following command:

./mill scoverage.xmlReportAll

The report will be generated at this location out/scoverage/xmlReportAll.dest/scoverage.xml

Formatting Scala Code

Code needs to be formatted according to scalafmt rules. To run scalafmt on all the source code using:

./mill mill.scalalib.scalafmt.ScalafmtModule/reformatAll __.sources

or the much shorter:

./mill reformatAll __.sources

or in watch mode to reformat changed files:

./mill -w mill.scalalib.scalafmt.ScalafmtModule/reformatAll __.sources

Formatting Elm Code

The evaluator tests utilize elm code. To reformat the elm code for those tests:

elm-format --elm-version=0.19 examples/morphir-elm-projects/evaluator-tests/src/Morphir/Examples/App/*.elm

If you don't have elm-format installed, you can either install it through npm or a different package manager like brew:

npm install -g elm-format

Alternatively, this can be done directly via npm run format, which is documented here

IntelliJ Setup for Windows

If you are using IntelliJ IDEA to edit morphir-scala's Scala code, you can create the IntelliJ project files via or use the BSP Setup option (BSP is the recommended approach):

.\mill -i mill.scalalib.GenIdea/idea

BSP Setup

If you are using Visual Studio Code, IntelliJ, or any of the Editors which support BSP you can also generate BSP config files via:

.\mill mill.bsp.BSP/install

You can also try the following to use the mill-contrib-bloop plugin to install and use the Bloop based BSP setup.

NOTE: The recommended BSP based setup for mill is to run: .\mill mill.bsp.BSP/install as mentioned above.

.\mill -i --import ivy:com.lihaoyi::mill-contrib-bloop:  mill.contrib.bloop.Bloop/install

Run Tests

.\mill -i __.test

or in watch mode:

.\mill -i -w __.test

Elm Tests

Documentation for the elm tests are located at examples/morphir-elm-projects/evaluator-tests/ReadMe.md

Formatting Code

Code needs to be formatted according to scalafmt rules. To run scalafmt on all the source code using:

.\mill -i mill.scalalib.scalafmt.ScalafmtModule/reformatAll __.sources

or in watch mode to reformat changed files:

.\mill -i -w mill.scalalib.scalafmt.ScalafmtModule/reformatAll __.sources
