Asymptote bug reproduce

README.md

This was to reproduce a bug I'd been having with Asymptote, but was actually me not passing the correct arguments. You need to explicitly pass -tex xelatex or whatever TeX engine you're using, and this example has been updated to do that in the Makefile.

circle.asy

size(4 inch);

draw(unitcircle);
label("$A = \pi r^2$");

latexmkrc

sub asy {return system("asy \"$_[0]\"");}
add_cus_dep("asy","eps",0,"asy");
add_cus_dep("asy","pdf",0,"asy");
add_cus_dep("asy","tex",0,"asy");

Makefile

%.pdf: %.tex
	latexmk --xelatex $<

test_external.pdf: circle.tex circle_0.eps circle.pre

circle.tex circle_0.eps circle.pre: circle.asy
	asy -inlinetex -tex xelatex $<
