Draw a shape with operation on parameters in Tikz

I want to draw a shape that I want to reuse. This shape is defined by geometrical input parameters (distances, radii) in a newcommand. Thus I want to perform some operations to define for example the center of my shape for example.

Maybe I am not treating thos problem correctly as I also want this shpae to work with the node proprties tu use the anchors and not only the origin of the shape for placement.

Here my small code. Thank you in advance.

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz


newcommandhinge[3] % #1 = name , #2 = rotation angle

draw[black, line width=1mm] (#1-#3,#2+#3)--++(1,0)--++(0:0) arc(0:180:-1)--++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)--++(-1,0)--cycle;



begindocument


begintikzpicture
hinge(0,0,1);
draw[red] (0,0) circle (0.1);
endtikzpicture
enddocument

You could also use a rectangular node but with a border and filling based on path picture option.

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz
usetikzlibrarypositioning

begindocument
begintikzpicture[hinge/.style 2 args=
 path picture=(path picture bounding box.north east)
 --([xshift=#2]path picture bounding box.north) arc(0:-180:#2) 
 -,
 hinge/.default=5mm
]

node[minimum width=4cm, minimum height=2cm,
, hinge] (a) Some text inside;
node[minimum width=2cm, minimum height=1cm,
, hinge=fill=red!302mm, above right=0pt of a] (b) Test;

node[minimum width=2cm, minimum height=1cm,
, hinge=draw=green,fill=blue!302mm, right= of a] (c) Test 2;
endtikzpicture
enddocument

I probably misread the question but if you want to give the thing node-like anchors, you may want to use a pic. In the following example, I give the thing the name X and draw a 45 degree line from its north east corner.

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz
tikzsetpics/.cd,
hinge/.style args=#1/#2/#3code=
draw[black, line width=1mm] (#1-#3,#2+#3)--++(1,0)--++(0:0) arc(0:180:-1)--++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)--++(-1,0)--cycle;



begindocument
begintikzpicture
pic[local bounding box=X] at (0,0) hinge=0/0/1;
draw (X.north east) -- ++ (1,1);
draw[red] (0,0) circle (0.1);
endtikzpicture
enddocument

When you create a command with newcommand, the arguments must be given within pairs of braces, so for the command to work you would need to use hinge001. To preserve the usage syntax and keep the command TikZ-like, you can use xparse:

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz
usepackagexparse

NewDocumentCommandhinge
 > SplitArgument2, r() % #1 = name , #2 = rotation angle
 %
 hingeMAIN#1%
 
newcommandhingeMAIN[3]%
 draw [black, line width = 1mm]
 (#1-#3,#2+#3)--++(1,0)--++(0:0) arc(0:180:-1)--++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)--++(-1,0)--cycle;


begindocument

begintikzpicture
hinge(0,0,1);
draw[red] (0,0) circle (0.1);
endtikzpicture
enddocument

The argument specification > SplitArgument2, r() says that there is a required argument delimited by () which will be pre-processed by the SplitArgument, which will split the input argument in 2+1 items separated by a ,. This command will transform (0,1,2) into 012, which is then passed to hingeMAIN, which expects braced arguments and does the drawing. The ; after the hinge command is not necessary.

Thank you for your fast answer!!! I feel stupid because of the synthax of my command... anyway, is it the right way to make a macro-shape to reuse in tikz or is there an elegant way?

I think xparse is the best way to easily create custom-delimited commands. The other way to to that would be defhinge(#1,#2,#3)<stuff here>, but this would be much more fragile than the xparse version, so I think it's as elegant as it can get :)

I had the same idea as @marmot: you should use a pic for this -- but I really like Ignasi's approach too!

Most of the solutions above do not seem to handle your requirement about node coordinates and the shapes are not styled further. It is easy to do both using pics, which you can read more about in section 18.2 of the tikz manual (version 3.0.1a).

Specifically, you can create something like:

enter image description here

using the code:

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz

tikzset
 pics/hinge/.style args = #1,#2% name, style
 code = 
 draw[black, line width=1mm, #2]
 (0,0)--++(1,0)--++(0:0) arc(0:180:-1) node[pos=0.5](#1)
 --++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)
 --++(-1,0)--cycle;
 
 


begindocument

 begintikzpicture
 draw (4,4) pichinge=first,blue;
 pic at (0,0) hinge=second,red,rotate=30;
 draw (0,4) pichinge=third,scale=0.4;
 draw[thick,->](first)--(second);
 endtikzpicture

enddocument

As I have shown, you can place a pic using either a draw command or a pic command. I have define a pic called hinge that takes two mandatory arguments:

the node name, which is in the center of the pic

and any styling

Both arguments to hinge are mandatory but you can omit one of them by using a comma:

draw (4,0) pichinge=fourth,;

is perfectly valid -- but be careful because you will get a nasty error message if you try:

draw (4,0) pichinge=fourth;

Finally, as pics are placed relative to the point that they are placed (using draw or pic), I dropped your (#1-#3,#2+#3). If this is really needed it is easy enough to add back in as pics can take many arguments, although at some point it becomes easier to use keys.

node[minimum width=4cm, minimum height=2cm,

node[minimum width=2cm, minimum height=1cm,

using the code:

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz

tikzset
 pics/hinge/.style args = #1,#2% name, style
 code = 
 draw[black, line width=1mm, #2]
 (0,0)--++(1,0)--++(0:0) arc(0:180:-1) node[pos=0.5](#1)
 --++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)
 --++(-1,0)--cycle;
 
 


begindocument

 begintikzpicture
 draw (4,4) pichinge=first,blue;
 pic at (0,0) hinge=second,red,rotate=30;
 draw (0,4) pichinge=third,scale=0.4;
 draw[thick,->](first)--(second);
 endtikzpicture

enddocument

As I have shown, you can place a pic using either a draw command or a pic command. I have define a pic called hinge that takes two mandatory arguments:

the node name, which is in the center of the pic

and any styling

Both arguments to hinge are mandatory but you can omit one of them by using a comma:

draw (4,0) pichinge=fourth,;

is perfectly valid -- but be careful because you will get a nasty error message if you try:

draw (4,0) pichinge=fourth;

Thank you very much all for your fast answer. Pic seems to be dedicated to what I try to do!

I had the same idea as @marmot: you should use a pic for this -- but I really like Ignasi's approach too!

Specifically, you can create something like:

enter image description here

using the code:

documentclass[border=2mm]standalone %<--- standalone
usepackagetikz

tikzset
 pics/hinge/.style args = #1,#2% name, style
 code = 
 draw[black, line width=1mm, #2]
 (0,0)--++(1,0)--++(0:0) arc(0:180:-1) node[pos=0.5](#1)
 --++(1,0)--++(0,-2.1)--++(-1,0)--++(0:0) arc(0:180:1)
 --++(-1,0)--cycle;
