I want to dynamically include functions from files based on condition.

Below code gives you an Idea.

File1.jl

```julia
function foo()
    println("In File1.jl")
end

```

File2.jl

```julia
function foo()
    println("In File2.jl")
end

```

Main.jl

```julia
function main(get_func_from)
    if get_func_from=="File1.jl"
        include("File1.jl")
        foo()
    end
end

```

Please note that I don’t want to include File1, File2 under global scope and want to call foo and include file only when needed.

You cannot do that. `include` works only at global scope for the same reason as `eval` only works at global scope (`include` really is eval-this-file), namely performance. If you could eval into local scope, Julia’s compilation-scheme would not work anymore. This limitation is really at the heart why Julia is fast.

Try to formulate your problem as a dispatch problem instead. Or just call into different functions in a if-else statement.
