How to Access an Object Created Inside A Module In Julia?

2 minutes read

To access an object created inside a module in Julia, you need to use dot notation to specify the module name followed by the object name. For example, if you have a module named MyModule with an object named myObject, you can access it by typing MyModule.myObject. This allows you to access and use the object defined inside the module in your Julia code.


How to check the contents of a module in Julia?

To check the contents of a module in Julia, you can use the names function. Here is an example of how to do this:

  1. Load the module you want to inspect by using the using or import keyword:
1
using MyModule


  1. Use the names function to retrieve the names of all the variables, functions, and types defined in the module:
1
names(MyModule)


This will return an array of symbols representing the names of all the objects defined in the module. You can then inspect each object further by using the typeof function or by accessing its properties and methods.


Alternatively, you can also use the workspace function to list all the variables and modules currently in the workspace:

1
workspace()


This will display a list of all the variables and modules currently available in the workspace, including the module you are interested in.


How to access a variable defined inside a module in Julia?

To access a variable defined inside a module in Julia, you can use dot syntax to specify the name of the module followed by a dot and the name of the variable. For example, if you have a module called MyModule and it contains a variable named myVariable, you can access it like this:

1
2
3
4
using MyModule

value = MyModule.myVariable
println(value)


Make sure that the module is loaded into the current environment using the using keyword before trying to access its variables.


How to call a function defined inside a module in Julia?

To call a function defined inside a module in Julia, you need to first import the module using the using keyword or the import keyword. Then, you can call the function using the dot syntax, which involves typing the module name followed by a dot and then the function name.


Here is an example demonstrating how to call a function defined inside a module named MyModule:

 1

# Define a module named MyModule
module MyModule
    export my_function

    function my_function()
        println("Hello from my_function!")
    end
end

# Import the module
using .MyModule

# Call the function defined inside the module
MyModule.my_function()


In the code above, we define a module named MyModule with a function my_function. We then import the module using using .MyModule and call the function my_function using MyModule.my_function().
