Combining calc and perpendicular coordinates in tikz

As it is described there, the following does not compile:

documentclassreport

usepackagetikz
usetikzlibrarycalc

begindocument
begintikzpicture
node at (0, 0) (node1) Hello;
node at (0, -2) (node2) World;

% working:
draw ($ (node1.south) + (1,0) $) to ( node1.south |- node2.north);

% not working:
draw ($ (node1.south) + (1,0) $) to ( ($ (node1.south) + (1,0) $) |- node2.north);

endtikzpicture
enddocument


Why? How to make it work?

The syntax of the line to operation given in the manual is to place |- between two coordinates:

line to

|-

path ... -| < coordinate or cycle> ...;

path ... |- < coordinate or cycle> ...;

You just have to write in your code:

draw ($ (node1.south) + (1,0) $) to ($ (node1.south) + (1,0) $) |- (node2.north);


instead of

draw ($ (node1.south) + (1,0) $) to ( ( ( $ (node1.south) + (1,0) $) |- node2.north);`


Your code becomes like this:

documentclassreport

usepackagetikz
usetikzlibrarycalc

begindocument
begintikzpicture
node at (0, 0) (node1) Hello;
node at (0, -2) (node2) World;

% working:
%draw ($ (node1.south) + (1,0) $) to ( node1.south |- node2.north);

% now working too:
draw ($ (node1.south) + (1,0) $) to ($ (node1.south) + (1,0) $) |- (node2.north);
endtikzpicture
enddocument
