I was originally julia 0.3.1 on windows 7
this is on Macosx 10 julia 0.3.2
I loaded the file LogParse.jl below and then in the repl ran
reload("LogParse.jl")
methods(isless)
ary1 = LogParse.DayPriceText[]
push!(ary1,LogParse.DayPriceText(4,"a1",1))
push!(ary1,LogParse.DayPriceText(2,"a1",1))
push!(ary1,LogParse.DayPriceText(6,"a1",1))
sort(ary1)
sort(ary1,lt=LogParse.isless)
I get the same messages - methods(isless) shows that it's loaded
but the sort can't find it, even when I try to specify the function
#in file LogParse.jl ###########
module LogParse
export DayPriceText
import Base.isless
type DayPriceText
a1::Uint32
b1::ASCIIString
a2::Uint32
end
function isless(a::DayPriceText, b::DayPriceText)
if (a.a1 < b.a1)
return true
else
return false
end
end
end
######
Many thanks.
Kind regards, John
