I'm trying to find the minimum x coordinate in a set of TikZ coordinates.
Consider this code
documentclass[tikz]standalone
usetikzlibrarypositioning

newdimenxmin
xmin=10000pt
newdimeny
begindocument
begintikzpicture[every node/.style=draw]
node (1) 182;

node[below=of 2] (3) 74632;
path (1.west); pgfgetlastxyxy
ifdimx<xmin xmin=x fi
fill[red] (xmin,y) circle (1pt);

fill[red] (xmin,y) circle (1pt);
path (3.west); pgfgetlastxyxy

endtikzpicture

foreach i in 1,2,3
path (i.west); pgfgetlastxyxy
ifdimx<xmin xmin=x fi
fill[red] (xmin,y) circle (1pt);
endtikzpicture
enddocument
These are the outputs of the first code (left) and the second code (right) side by side:
Look at the dot at the bottom. The first code gives the intended output, but the second doesn't.
Why? And how to modify the foreach loop in the second code so that it gives the same output as the first?

In the foreach variant, you are in a group when setting the dimension, so the "outside" value won't change. So you need to make the dimension global (or smuggle it out of the group). Here I made it global by just adding global before xmin=x.

foreach i in 1,2,3
path (i.west); pgfgetlastxyxy
ifdimx<xmin globalxmin=x fi
fill[red] (xmin,y) circle (1pt);

ADDENDUM: Of course, there are loops which do not introduce groups. The arguably simplest of those is the built-in loop.

@JouleV You only change the local but not the outside value. (This is also the reason whydraw[blue] ...renders only the...but not every other path blue. Likewise, if you saytikz[blue]....everything in thetikzpicturewill be blue, but not outside, and so on.) In TeX all macros are local unless you explicitly make them global.

You can use a different loop that doesn't do grouping. Instead of i you use simply #1.

@JouleV The first line sets a temporary function according to the code in the third argument; the second line does a loop from the starting point (first argument) to the final point (second argument). No fancy syntax likeforeach, but for most cases it's sufficient. You find a more elaborate implementation at tex.stackexchange.com/a/329628/4427

@JouleV The first line sets a temporary function according to the code in the third argument; the second line does a loop from the starting point (first argument) to the final point (second argument). No fancy syntax likeforeach, but for most cases it's sufficient. You find a more elaborate implementation at tex.stackexchange.com/a/329628/4427

You can use a different loop that doesn't do grouping. Instead of i you use simply #1.
