Memoize Pkg? Bad use of Metaprogramming?

Derrp yes that should be in the returned expression itself. No worries I’ll take another crack at it. Thanks. Sorry no coffee in me yet. I also forgot to quote the remove file in the free_memo macro - yikes.

Here this should be better

using JLD2

macro memoize(cache_var)
    filename = String(cache_var) * ".jld2"
    quote
        if !isfile( $filename )
            @save $filename $cache_var
        else 
            @load $filename $cache_var
        end
    end
end

macro memoize(cache_var, fn)
    filename = String(cache_var) * ".jld2"
    quote    
        if !isfile( $filename )
            $fn
            @save $filename $cache_var
        else
            @load $filename $cache_var
        end
    end
end

macro free_memo(cache_var)
    filename = String(cache_var) * ".jld2"
    quote
        if !isfile( $filename )
            @warn "Cache is already empty."
        else
            rm($filename)
        end
    end
end
