To access the extended help mode in Julia, you can use the "?" character followed by the name of the function, variable, or object that you want more information about. Typing "?function_name" in the Julia REPL will display detailed documentation about that specific function, including its arguments, return types, and usage examples. You can also use "?" on any module, type, or package to get information about its contents and usage. Using the extended help mode is a great way to quickly access documentation and learn more about Julia's built-in functions and packages.

What is the difference between the regular help mode and the extended help mode in Julia?
In Julia, the regular help mode provides a brief description of a function or a module, while the extended help mode provides a more detailed description, including information on the function's usage, parameters, and examples of how to use it. The extended help mode is more comprehensive and is useful for users who require more detailed information about a specific function or module.
What is the recommended way to use the extended help mode in Julia?
The recommended way to use the extended help mode in Julia is to use the ? or help() function followed by the function or module name you want information about. For example, to get information about the sin function, you can type ?sin or help(sin) in the Julia REPL. This will display detailed information about the function, including its signature, purpose, and usage examples. Additionally, you can use the apropos() function to search for functions or modules containing a specific keyword.
What is the purpose of the extended help mode in Julia?
The purpose of the extended help mode in Julia is to provide additional details, examples, and documentation for a specific function or module. It is designed to offer more in-depth information than the standard help function, making it easier for users to understand and utilize different features of the language. This can be especially helpful for beginners or those looking to explore more advanced topics in Julia programming.
How to access the extended help mode from the Julia command line?
To access the extended help mode from the Julia command line, you can use the "?" question mark symbol followed by the name of the function, module, or variable you want information about.
For example, if you want to get detailed information about the "cos" (cosine) function, you can type the following command in the Julia command line:
1
|
?cos
|
This will give you detailed information about the "cos" function, including its syntax, usage, and examples. You can also use the "??" double question mark symbol to get even more information about the function or variable.
You can use this extended help mode to get information about any function, module, or variable in Julia. It is a useful tool for quickly looking up information and understanding how to use different features of the language.
