Xtext hint feature in sysml textual editor

[coldzeraaaaa]

Dear SysML Team,

I am currently working on enabling XText’s text hint feature for SysML’s text editor and have encountered some challenges.
In the GenerateKerMLExpressions.mwe2 file, my initial attempt involved commenting out the line “fragment = ui.contentAssist.ContentAssistFragment2 {}” and uncommenting “fragment = NoContentAssistAntlrGeneratorFragment {}“. However, this resulted in the parser not being generated.

Subsequently, I attempted to address the issue by uncommenting “fragment = ui.contentAssist.ContentAssistFragment2 {}” and adding “fragment = parser.antlr.XtextAntlrGeneratorFragment2 {}“. Unfortunately, this led to an error in InternalSysMLParser.java stating that “The code for the static initializer is exceeding the 65535 bytes limit.”

I am seeking guidance on how to resolve this issue. Alternatively, I would appreciate any suggestions on alternative methods to incorporate the hint feature into the SysML textual editor.

Thank you in advance for your assistance.

Best regards,
Levent
