""" prompt
I want to have my main function loop running and execute a user-defined script: usermodule_1.jl, 
  usermodule _2.jl and so on. 
1). Write a main.jl with main function loop to execute user-defined scripts sequentially. 
2). Store each script result in respective variable. 
3). make sure no global variables contamination Give me a complete example.

"""To achieve your goal of running user-defined scripts sequentially within a main function loop in Julia, storing each script's result in a respective variable, and ensuring no global variable contamination, you can follow the example below:
Create a main.jl script with a main function loop to execute user-defined scripts sequentially:"""

# -------------------------------------------- main.jl ------------------------------------------- #
function main()
    script_results = Dict{String, Any}()

    for i in 1:2
        script_name = "usermodule_$i.jl"
        include(script_name)
        
        # Assuming each user-defined script has a function named 'run_script' that returns a result
        result = run_script()
        
        script_results[script_name] = result
    end

    return script_results
end

results = main()


# ---------------------------------------- usermodule_1.jl --------------------------------------- #
module UserModule1

export run_script

function run_script()
    # Your script logic here
    result = "Result from UserModule1"
    return result
end

end

# ---------------------------------------- usermodule_2.jl --------------------------------------- #
module UserModule2

export run_script

function run_script()
    # Your script logic here
    result = "Result from UserModule2"
    return result
end

end

"""    Ensure no global variable contamination by encapsulating each script's logic within a module and exporting only the necessary functions.

When you run main.jl, it will sequentially execute usermodule_1.jl and usermodule_2.jl, store the results in a dictionary script_results, and return it. Each script's logic is encapsulated within its module to prevent global variable contamination.

This approach allows you to run user-defined scripts sequentially, store their results, and maintain a clean and modular structure in your Julia code.
