Ahoi, since i recently updated my ConTeXt beta, Lua function string.format behaves differently, i.e. type checks are stricter. I guess it’s due to switching to Lua 5.3 in LuaTeX?

This is indeed one of the changes in 5.3 (more about that at the ctx meeting). Anyway, format is a bit unstable over time anyway, which is why in context we have string.formatters with some more options (cld manual): print(string.formatter("%r",1)) print(string.formatter("%r",1.1)) print(string.formatter("%p",1)) print(string.formatter("%p",1.1)) etc. On the average its also faster than string.format. It means that we could make the transition to 5.3 without too much hassle (very little had to be adapted and luigi and i are running context with 5.3 for quite a while now).

E.g. this:

if tonumber(string.format('%d', value)) == value then ...

throws

bad argument #2 to 'format' (number has no integer representation)

Since I just need to check if the number is integer, this works:

if tonumber(value) == math.floor(value) then ...

This also affects Peter Münster’s grph-downsample module; please find a fixed version attached. (Decimal pixel sizes make no sense anyway, so I just "floored" them.)

better round them
