Architecture of logi.Cloud Architecture and Components ● 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

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

Challenges: Dependencies Making logi.CAD3 ready for the Cloud ● Dependency Analysis of Java Code using CDA C lass D ependency A nalyzer ● 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: Dependency Categorizatjon Making logi.CAD3 ready for the Cloud

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

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 ● ...

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, …

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

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

Challenges: Additjonal concerns Making logi.CAD3 ready for the Cloud LC3/logi.CLOUD: General interface of LC3 projects: public interface Lc3Project extends Comparable<Lc3Project> { [...] File getFile(String name); }

Challenges: Additjonal concerns Making logi.CAD3 ready for the Cloud LC3: Using Eclipse IProject to retrieve fjles @Override public File getFile(fjnal String name) { fjnal IFile eclipseFile = this.eclipseProject.getFile(name); return new File(eclipseFile.getLocation().toOSString()); } logi.CLOUD: Using Language Server Project Manager to retrieve fjles (LC3 Server; JAVA) @Override public File getFile(fjnal String name) { fjnal URI baseDir = this.projectManager.getBaseDir(); return new File(baseDir.toFileString() + name); }
