Local-scoped coordinate names in tikz?
8
I think I just discovered (!) that coordinates names are global in tikz:
documentclassarticle
usepackage[T1]fontenc
usepackage[utf8]inputenc
usepackagetikz
begindocument
begintikzpicture[black]
draw(0,0) coordinate(alfa) -- (3,0) coordinate(beta);
endtikzpicture
begintikzpicture[blue]
draw (alfa) -- (beta);
endtikzpicture
begintikzpicture[red]
beginscope
draw(1,0) coordinate(alfa) -- (2,0) coordinate(beta);
endscope
endtikzpicture
begintikzpicture[green]
draw (alfa) -- (beta);
endtikzpicture
enddocument
...and I really expected
- an error in the second
tikzpicture(I am not usingremember picture!), and - a
(0,0)--(3,0)green line...
So,
am I correct that coordinate names are global to all
tikzpictures?As a bonus question, is it possible to create local coordinate names?

+1 I didn't know that either. On page983we find this, and I quote:pgfgetlastxymacro for xmacro for y Since (x,y) coordinates are usually assigned globally, it is safe to use this command after path operations

Yes, I've observed that before. And I think your interpretation is correct, and you can make coordinates "local" by using name prefix.

begindocument
begintikzpicture[black]
draw(0,0) coordinate(alfa) -- (3,0) coordinate(beta);
endtikzpicture
begintikzpicture[blue]
draw (alfa) -- (beta);
endtikzpicture
begintikzpicture[red,name prefix=Rmano]
beginscope
draw(1,0) coordinate(alfa) -- (2,0) coordinate(beta);
endscope
endtikzpicture
begintikzpicture[green]
draw (alfa) -- (beta);
endtikzpicture
