Raku UML::Translators

In brief

This repository is for a Raku package for the translations of code into Unified Modeling Language (UML) specifications and vice versa.

Currently, the package only translates Object-Oriented Programming (OOP) Raku code into:

• The Domain Specific Language (DSL) of PlantUML

• Argument specification of the UML class diagram function UMLClassGraph of the Mathematica / Wolfram Language (WL) package [AAp1]

Future plans

A fully fledged version of this package would translate:

• C++, Java, Kotlin, or Raku code into UML specs

• UML specs into C++, Java, Kotlin, or Raku code

Currently, only UML specs are generated to PlantUML's DSL and a much poorer WL DSL. Ideally, subsequent versions of this package would be able to use UML specifications encoded in XML and JSON.

Installation

From zef's ecosystem

zef install UML::Translators

From GitHub

zef install https://github.com/antononcube/Raku-UML-Translators.git 

Command Line Interface (CLI)

> to-uml-spec --help
Usage:
  to-uml-spec [--type=<Str>] [-I=<Str>] [--attributes] [--methods] [--conciseGrammarClasses] [--format=<Str>] <packageName> -- Make a UML diagram for a specified package.
  
    <packageName>              Package name.
    --type=<Str>               Type of the UML diagram. [default: 'class']
    -I=<Str>                   Using include path to find libraries. [default: '']
    --attributes               Should the class attributes be included in the UML diagrams or not? [default: True]
    --methods                  Should the class methods be included in the UML diagrams or not? [default: True]
    --conciseGrammarClasses    Should grammar classes be shortened or not? [default: True]
    --format=<Str>             Format of the output, one of 'Plant', 'PlantUML', 'WL', 'WLUML', or 'Whatever'. [default: 'PlantUML']

Usage examples

Using the script to-uml-spec:

to-uml-spec --/methods --/attributes "Lingua::NumericWordForms"

With this shell command we generate a Plant UML spec for the package "Chemistry::Stoichiometry" and create the UML diagram image with a local PlantUML JAR file (downloaded from [PUML1]):

to-uml-spec --/methods --/attributes 'Chemistry::Stoichiometry' | java -jar ~/Downloads/plantuml-1.2022.5.jar -pipe -tjpg > /tmp/myuml.jpg

UML for ad hoc classes

use UML::Translators;
module MyPackageClass {
  role A { method a1 {} }
  class B does A { has $!b0; method b1 {} }
  class C does A is B { has $!c0; method c1 {} }
}
to-uml-spec('MyPackageClass')

# @startuml
# class MyPackageClass::B  {
#   {field} $!b0
#   {method} BUILDALL
#   {method} a1
#   {method} b1
# }
# MyPackageClass::B --|> MyPackageClass::A
# 
# 
# class MyPackageClass::A <<role>> {
#   {method} a1
# }
# 
# 
# class MyPackageClass::C  {
#   {field} $!b0
#   {field} $!c0
#   {method} BUILDALL

# MyPackageClass::C --|> MyPackageClass::B

UML for packages

Get PlantUML code for the package 'Chemistry::Stoichiometry':

say to-uml-spec('Chemistry::Stoichiometry'):!methods:!attributes
