I have an mtxrun on a .tex file that has problems I need to debug. The .tex file handles well, but whenMETAPOST has a go, it crashes. But after the run, I cannot inspect what source was fed to METAPOST. Can I inspect that (outside of what the log tells me)? In this case, I know METAPOST is fed: picture pic; x:=80.000; y:=200.000; w:=133.000; h:=53.000;pic := ApplicationComponentLogo( w, h, typeString) shifted (x, -y); draw pic; but the log says this is wrong: metapost log > >> unknown picture pic metapost log > >> ApplicationComponentLogo metapost log > ! Equation cannot be performed (unknown picture=numeric). metapost log > <to be read again> metapost log > ( metapost log > <*> ... h:=53.000;pic := ApplicationComponentLogo( metapost log > w, h, typeString) shifted... SoI need to inspect what is fed to METAPOST to see why METAPOST thinks pic or ApplicationComponentLogo have not been defined. G
