  • logi.CAD3 ofgers public API
  • logi.CAD3 is a tool integrated by OEMs
  • API is pretty comprehensive
  • Makes it quite simple to
  • Extend logi.CAD3 itself
  • Create stand-alone applications (with extensions)

Key Enablers Making logi.CAD3 ready for the Cloud

  • Eclipse projects
  • Xtext: language mechanisms
  • LSP4J: JSON RPC over WebSockets (incl. support for LSP)
  • Eclipse Theia: Frontend/Backend framework
  • Eclipse GLSP: Graphical Language Server Protocol
  • Eclipse Che: future execution context of logi.CLOUD
slide-18

Challenges: Dependency Categorizatjon Making logi.CAD3 ready for the Cloud

  • UI dependencies
  • Rely on Eclipse UI to work
  • Example: custom editors
  • Eclipse dependencies
  • Rely on common Eclipse functionality (but no UI)
  • Example: Eclipse builders, Workspace
  • OSGi
  • Low-level Eclipse functionality
  • Example: Service access
  • OK
  • Functionality that works in any Java environment
  • Example: (Generated) Xtext parsers
slide-19
SLIDE 19

Challenges: Dependencies Making logi.CAD3 ready for the Cloud

  • Dependency Analysis of Java Code using CDA
  • Class Dependency Analyzer

http://www.dependency-analyzer.org/

  • Handles class, package, and plug-in level dependencies
  • Can visualize dependency hierarchies
  • Dependencies exported to CSV format
  • Categorizatjon and aggregatjon in Spreadsheet Sofuware
  • Identifjcation of (potentially) problematic dependencies

Challenges: Workspace handling Making logi.CAD3 ready for the Cloud

  • Challenge:
  • Eclipse Workspace depending functionality (Project Index; H2-based)
  • Theia IDE does not know Eclipse Workspaces
  • Solutjon:
  • Custom “Cloud-aware” Workspace implementation
  • Will behave difgerently to Eclipse fjle system
  • Limits possibility of shared code with logi.CAD3
slide-22
SLIDE 22

Challenges: Workspace handling Making logi.CAD3 ready for the Cloud

  • Workspace types being used
  • Theia Backend: FS/TS-based workspace
  • logi.CAD3 Server: Cloud-aware workspace
  • logi.CAD3 Build Server: Eclipse workspace (generated; snapshot)
  • logi.CAD3 T

arget Comm Server: none needed

Outlook The (near) Future

  • Full support for C/C++ editjng
  • Based on clangd
  • Diagnostjc Features
  • View variable values
  • Contjnue FBD support
  • Variable table
  • Context menus
  • Full editing, e. g. routing for connections
  • Copy-paste
  • ...
slide-24
SLIDE 24

Outlook The (far) Future

  • Integratjon of new platgorms
  • Licensing issues/challenges
  • Workspace management
  • Based on Eclipse Che
  • Decision on the executjon platgorm for logi.CLOUD
  • RedHat OpenShift, MS Azure, …
slide-25
SLIDE 25

Outlook The (far) Future

  • Ofgering logi.CLOUD as an integrable solutjon
  • logi.cals products typically sold as integrable framework
  • OEMs use our product and add branding
  • OEMs expect a plugin infrastructure
slide-26
SLIDE 26

Summary Findings, Recommendatjons

  • Build Proof-of-Concept Prototypes
  • Based on well-defjned use-cases
  • Getting to know new technologies and frameworks
  • Helps to estimate the time frame for developing the actual product
