Morphir Command Line Tools

At the moment, Morphir provides two CLI programs that provide the tools that morphir offers, morphir-elm and morphir. morphir-elm is the first program created and may be deprecated in the future, so we advise that you use morphir whenever possible and only use morphir-elm if the feature you intend to use isn't currently available in morphir.

Compile (Elm)​

Morphir revolves around the Intermediate Representation (IR), which is the data format for storing logic. Morphir users compile their business logic into the IR using morphir's compiler tools. For Elm-authored logic, is done through the following:

morphir-elm make
moprhir make

Options include:

Usage: morphir-elm make [options]
Usage: morphir make [options]

Translate Elm sources to Morphir IR

Options:
-p, --project-dir <path>  Root directory of the project where morphir.json is located. (default: ".")
-o, --output <path>       Target file location where the Morphir IR will be saved. (default: "morphir-ir.json")
-t, --types-only          Only include type information in the IR, no values. (default: false)
-f, --fallback-cli        Full rebuild. Only available for "morphir-elm make" (default: false)
-h, --help                display help for command

Visualize​

Morphir contains tools to interact with, learn, and test Morphir applications. This can be invoked via:

morphir-elm develop

Options include:

Usage: morphir-elm develop [options]

Start up a web server and expose developer tools through a web UI

Options:
  -p, --port <port>         Port to bind the web server to. (default: "3000")
  -o, --host <host>         Host to bind the web server to. (default: "0.0.0.0")
  -i, --project-dir <path>  Root directory of the project where morphir.json is located. (default: ".")
  -h, --help                display help for command

Note that the default http://0.0.0.0:3000 sometimes needs to be replaced with http://localhost:3000 depending on the host environment.

Generate​

Morphir provides tools to generate useful things from a Morphir IR.

morphir-elm gen

Options include:

Usage: morphir-elm gen [options]

Generate code from Morphir IR

Options:
  -i, --input <path>                                               Source location where the Morphir IR will be loaded from. (default: "morphir-ir.json")
  -o, --output <path>                                              Target location where the generated code will be saved. (default: "./dist")
  -t, --target <type>                                              Language to Generate (Scala | SpringBoot | cypher | triples | TypeScript). (default: "Scala")
  -m, --modules-to-include <comma.separated,list.of,module.names>  Limit the set of modules that will be included.
  -h, --help                                                       display help for command

Generate Scala​
