show
show(x)
Write an informative text representation of a value to the current output stream. New types should overload show(io, x) where the first argument is a stream. The representation used by show generally includes Julia-specific formatting and type information.
Examples
julia> show(10)
10
julia> show("Hello, Julia!")
"Hello, Julia!"
julia> show([1, 2, 3])
[1, 2, 3]The show function is used to generate an informative text representation of a value and output it to the current output stream. It is commonly used to display the value of an object or variable in a human-readable format. The representation generated by show often includes specific formatting and type information relevant to Julia.
Here are some examples demonstrating the usage of show:
-
Show an integer value:
julia> show(10) 10The
showfunction outputs the integer value10to the current output stream. -
Show a string value:
julia> show("Hello, Julia!") "Hello, Julia!"In this example,
showgenerates a text representation of the string"Hello, Julia!"and outputs it to the output stream. - Show an array:
julia> show([1, 2, 3]) [1, 2, 3]The
showfunction can be used to display the contents of an array. In this case, it outputs the array[1, 2, 3].
Note that for new types, it is possible to define a custom show method that overloads show(io, x), where io is the output stream and x is the object being displayed. This allows developers to define a custom representation for their own types.
Please make sure to refer to the official Julia documentation for more detailed information on the show function and its usage.
