Calling "get" anywhere in a function makes a global variable undefined.
Can anyone please help explaining the following?
1) without calling "get", the global variable is fine:
a=0
>
> Dicta = Dict{Int,Int}()
>
> function testGlobal()
>
> println(a)
>
> merge!(Dicta, Dict(1=>1))
>
> # a=get(Dicta, 1, 0)
>
> println(a)
>
> nothing
>
> end
>
>
> julia> testGlobal()
0
0
2) calling "get" (same code as above except uncommenting the "get"
statement) and the global variable becomes undefined:
a=0
>
> Dicta = Dict{Int,Int}()
>
> function testGlobal()
>
> println(a)
>
> merge!(Dicta, Dict(1=>1))
>
> a=get(Dicta, 1, 0)
>
> println(a)
>
> nothing
>
> end
>
>
> julia> testGlobal()
ERROR: UndefVarError: a not defined
in testGlobal() at /xxx/testType.jl:4
3) not calling the first println, the code works, but the global a is not
set:
a=0
>
> Dicta = Dict{Int,Int}()
>
> function testGlobal()
>
> # println(a)
>
> merge!(Dicta, Dict(1=>1))
>
> a=get(Dicta, 1, 0)
>
> println(a)
>
> nothing
>
> end
>
>
>
julia> testGlobal()
1
