[lltx] debugging when luaotfload can't find fonts

[Will Robertson]

Hi,

I'm having trouble loading fonts and I don't know how to debug the problem.

My otfl-names.lua cache contains, for example,

>   {
>    ["familyname"]="XB Zar",
>    ["filename"]={ "/Users/will/Library/Fonts/XB Zar/XB Zar.ttf", false },
>    ["fontname"]="XBZar",
>    ["fullname"]="XB Zar",
>    ["names"]={
>     ["family"]="XB Zar",
>     ["fullname"]="XB Zar",
>     ["psname"]="XBZar",
>     ["subfamily"]="Regular",
>    },
>    ["size"]={},
>    ["slant"]=0,
>    ["weight"]=400,
>    ["width"]=5,
>   },


and yet when I run

> \documentclass{article}
> \usepackage{fontspec}
> \begin{document}
>   \huge
>   \fontspec[Script=Arabic,Numbers=Arabic]{XB Zar}
>   test
> \end{document}


I get the following:

What's going wrong here? Could this error messages be a little more clear?
