I’m familiarizing myself with a package written by others. What I’m curious to know is how an object is printed at the console when I type this object’s name at REPL. I think the authors of the package overrode the default way of displaying and redefined it somewhere in the package. But I couldn’t locate the overridden display function as I don’t know the keywords by searching which I can find the redefinition.

In Matlab, such a customized display is achieved by overridden function of `disp`. I wonder the keyword in Julia. Could anyone leave me a hint? Thanks!!
