Conditionals within tikz node specification

Clash Royale CLAN TAG#URR8PPP

I would like to specify custom hierarchies of tikz nodes where I do a few geometry calculations related to text depth, text width, text height, and so on.

In the process of writing custom commands to automate some of these calculations, I end up wanting to use TeX conditionals mixed in with tikz code. I read in another question that pgfextra can be used for this. However, it seems that this only works at the level of the tikzpicture environment.

A minimal example of what I would like to do is the following:

documentclass[class=minimal, border=0pt]standalone

usepackagetikz

newififDebug
%Debugtrue
Debugfalse

newcommandMyNode
 node[anchor=north west,
 minimum width=5cm,
 minimum height=5cm,
 fill=green,
 pgfextraifDebug opacity=0.2,fi
 ] at (current page.north west) 

begindocument
begintikzpicture
 MyNode;
endtikzpicture
enddocument

The line containing pgfextra is giving me trouble. What should I do to conditionally change arguments to node?

Thanks!

Welcome to TeX.SE! Please try to avoid all pgfextra stuff. You can achieve almost everything with pgfkeys, also here.

documentclass[class=minimal, border=0pt]standalone

usepackagetikz

newififDebug
%Debugtrue
Debugfalse

tikzsetDebug/.code=ifDebugpgfkeysalsoopacity=0.2fi

newcommandMyNode
 node[anchor=north west,
 minimum width=5cm,
 minimum height=5cm,
 fill=green,
 Debug,
 ] at (current page.north west) 

begindocument
begintikzpicture
Debugtrue
 MyNode;
endtikzpicture
enddocument

If I comment out Debugtrue, I get.

With a Tikz style (implemented with the /.code handler) this is rather straightforward:

documentclass[class=minimal, border=0pt]standalone

usepackagetikz

newififDebug
Debugtrue
%Debugfalse

tikzset
 my node/.code=
 tikzset
 anchor=north west,
 minimum width=5cm,
 minimum height=5cm,
 fill=green,
 
 ifDebug
 tikzsetopacity=0.2
 fi
 


begindocument
begintikzpicture
 node[my node];
 Debugfalse
 node[my node] at (6,0);
endtikzpicture
enddocument

As mentioned by marmot in his answer you should stay away from pgfextra in general. My personal preference is also to stay away from custom commands where styles can do the same, but that really is personal.
