null - Lua Script:attempt to call global 'tonubmer' (a nil value) -


i new lua,i don't know why,does related environment or libarary?it drive me crazy, being search answer hours.

function gradient()    local maxstep = 10;    local starcolor="41b0f7";    local endcolor ="1622df";    local sb = tonubmer(string.sub(starcolor,1,2),16);    return sb; end print(gradient());

there 2 things going on here:

  1. lua standard library functions tonumber global variables.
  2. if try access global variable not exist (in case, tonu*bm*er) nil ny default.

i recommend using linting tool luainspect detect these typos before bite you.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
