Auto Fill in class structure from python?

[cessna85]

I've got a script that can recognize which functions are a __thiscall but I would like to also be able to fill in the class structure based on the newly added class funcs.

Is there a way to programmatically auto fill in a class structure?

I was also looking for this and found the UI function that performs this at

ghidra/Ghidra/Features/Decompiler/src/main/java/ghidra/app/plugin/core/decompile/actions/CreateStructureVariableAction.java

Lines 82 to 112 in a0205ff

	public void actionPerformed(ActionContext context) {
	ProgramLocation location = null;
	Program program = null;
	if (context instanceof DecompilerActionContext) {
	DecompilerActionContext decompilerActionContext = (DecompilerActionContext) context;
	if (decompilerActionContext.isDecompiling()) {
	Msg.showInfo(getClass(), context.getComponentProvider().getComponent(),
	"Decompiler Action Blocked",
	"You cannot perform Decompiler actions while the Decompiler is busy");
	return;
	}
	location = decompilerActionContext.getLocation();
	program = decompilerActionContext.getProgram();
	}
	else if (context instanceof ListingActionContext) {
	ListingActionContext listingContext = (ListingActionContext) context;
	// get the data type at the location and see if it is OK
	// make sure what we are over can be mapped to decompiler
	// param, local, etc...
	location = listingContext.getLocation();
	program = listingContext.getProgram();
	}
	else {
	return;
	}
	DecompileOptions decompileOptions = DecompilerUtils.getDecompileOptions(tool, program);
	FillOutStructureCmd cmd = new FillOutStructureCmd(location, decompileOptions);
	tool.executeBackgroundCommand(cmd, program);

While searching I found that

ghidra/Ghidra/Features/Decompiler/ghidra_scripts/CreateStructure.java

Line 55 in a0205ff

FillOutStructureCmd cmd = new FillOutStructureCmd(currentLocation, decompileOptions);

exists so there's already a Java script that can do this.

Note that you need to put your cursor on the first parameter to make this work for a "this" parameter. I've yet to figure out how to get that location from a function.
