ESC macro problem [message #52185] Tue, 06 August 2019 16:16 Go to next message

linux, svn 13505

I'm writing a macro and is trying to use either lambda or fn to create callable sub-routines
but find that ESC-functions like GetCursor() and Find() is not available in either.

If I put all the code in the macro itself it works fine, but has a lot of repeating code.

1. What must I do to have access to the ESC-functions within either a lambda or an fn?

2. Also, what is the 'instance' refered to in:
Quote:
. lambda(args) ! instance | Invokes lambda, using instance as instance for lambda execution (accessible via .name or self).


Below demonstrates the issue:
macro "PROBLEM" Ctrl+F8
{
	ClearConsole();
	cp = GetCursor();
	A = "STD";
	B = "COUT";
	
	//this works fine...
	#:cat(a, b, &x) { x = a + ">>>>>" + b; }
	
	c = "error";
	:cat(A, B, c);
	cout(c);
	
	
	//this fails with: [..] 'SetCursor' is not a lambda
	#:test(a, b)
	{
		SetCursor(0);
		if (Find("std::cout", 1, 1))
		{
			f = GetSelBegin();
			l = GetSelCount();
			SetCursor(f);
			Remove(l);
			s = a + "::" + b;
			Insert(s);
		}
	}
	
	:test(A, B);
	SetCursor(cp);
	
}


thx

I've updated another question: https://www.ultimatepp.org/forums/index.php?t=msg&th=107 42&start=0&
attaching a macro that clearly shows the duplications of code that should be in callable lambdas of fn's

Macros are really "methods of editor", and SetCursor etc.. are methods too, that is why you cannot invoke them in global functions. You need to define a method...

	.test = @(a, b)
	{
		SetCursor(0);
		if (Find("STD::COUT", 1, 1))
		{
			f = GetSelBegin();
			l = GetSelCount();
			SetCursor(f);
			Remove(l);
			s = a + "::" + b;
			Insert(s);
		}
	};
	
	test(A, B);

thx mirek, that works fine now

2nd question:
Is it possible to override ide menu-items and toolbar-buttons from macro's and call their real code
after I've done some 'pre-processing' of my own?
In other words I want to intercept the user-action and do something and then let the original method continue.
