I like to have separate .mp files to organize my Metapost projects. But I'm facing this error message when I try to input file within a macro
File names can't appear within macros. Even with this very clear message I'm wondering if there is a solution to call input files in a macro ? (package, extension, Metafun, Metafont, little hack, etc. ?)
def init = input var.mp draw (0,A)--(10,B)--(20,C); enddef; beginfig(1); init; endfig; end.
Thank you for your help.
