(UI layer) Implement UI

[ArchibaldBienetre]

Once #6 and #7 are done, we only need to write a UI to pass the right parameters to the application.

• @ArchibaldBienetre 's vote would be for JavaFX
  • https://www.baeldung.com/javafx
  • a more recent technology
  • comes with a serialization format (FXML) and grphical editor that has IDE integration
    • https://docs.oracle.com/javafx/2/get_started/fxml_tutorial.htm
    • https://www.oracle.com/java/technologies/javase/javafxscenebuilder-info.html
      • it seems with IntelliJ IDEA, there's a different Scene Builder to use https://www.jetbrains.com/help/idea/opening-fxml-files-in-javafx-scene-builder.html
      • looks like this
  • can be tested well https://testfx.github.io/TestFX/
    • docs: https://github.com/TestFX/TestFX/wiki/Queries

I'll explore JavaFX, FXML and TestFX, and create a LearningTest.

I will focus on focusing on

• file selection
  • https://docs.oracle.com/javafx/2/ui_controls/file-chooser.htm
• user error / exception handling
  • https://stackoverflow.com/questions/26361559/general-exception-handling-in-javafx-8#26365798 ?
• and testing
  • see TestFX mentioned above
  • some components like FileChooser or Alerts may not lend themselves to TestFX testing, maybe I can explore some options there (confirmed: link)

    • https://stackoverflow.com/a/59152238/1143126
    • ...

Made some great progress figuring out how to deal with Java modules and TestFX tests:
https://github.com/ArchibaldBienetre/javaFxTestGradle

• JavaFX application that can be run from the commandline ( ./gradlew run )
• TestFX test that can be run from gradle (e.g. ./gradlew clean check --info )
• TestFX test that can be run headless on CI
  • 🟢 https://app.circleci.com/pipelines/github/ArchibaldBienetre/javaFxTestGradle/3/workflows/112f63f6-8bfb-4290-ae76-f98d09386f4f/jobs/4
• TestFX test for FileChooser interaction
  • sigh... [Bug] Double click in FxFileChooserDialog does not return selected file Oliver-Loeffler/FXFileChooser#44
• move the file chooser UI over into csv2tex (some Module issues expected)
  • Add UI and dummy rendering #44

Once #43 and #44 are merged, this issue will be closed.
