How do i turn off specific auto analysis in headless? I need mangled name of a function

[anzosasuke]

Hello,

I am looking to print the mangled name of the function and turn off specific Demangler GNU analysis. I looked the DemanglerUtil and DemanglerObject(), but no luck to get the getMangledString() to work. Any help on this is greatly appreciated.

From a GhidraScript passed into headless with -prescript:

setAnalysisOption(currentProgram, "Demangler GNU", "false");

I did not test this, but used this existing script as an example:

ghidra/Ghidra/Features/Base/ghidra_scripts/TurnOffStackAnalysis.java

Lines 24 to 34 in 54e0ab1

	public class TurnOffStackAnalysis extends GhidraScript {
	public void run() throws Exception {
	setAnalysisOption(currentProgram, "Stack", "false");
	setAnalysisOption(currentProgram, "Function ID", "false");
	/*if(currentProgram.getCompilerSpec().getCompilerSpecID().getIdAsString().equals("windows")){
	setAnalysisOption(currentProgram, "Find and Create ASCII Strings", "true");
	}*/
	}
	}

Thanks so much. I used your java version. i was not able to replicate it in python. Any idea why?
Also, getMangledString() function in Demangled class, how would one use it?

Not sure why it didn't work in python for you...i'd have to see your script.

As far as I know, the Demangled interface is only for use by our internal demanglers. You would have to kick off demangling yourself (instead of using the analyzer) to get a hold of one of those objects.
