Console Input and Output

Luau provides the print function, which can be used to output one or more lines of information to the console.

In Eryx, this function is augmented to print more types. Printing tables will print a literal version of the table, rather than table: 0x.....

For more complex console interaction, @eryx/stdio is provided.

Using stdio, we can treat the console more like a file that we can read and write to. To read from the console, we can use stdio.readline(). stdio.write() allows us to write to the console without appending a new line at the end. As an example:

const stdio = require("@eryx/stdio")

stdio.write("What is 5+5: ")
local answer = stdio.readline()
if answer == "10" then
    print("Correct!")
end

We can see in this example that readline waited until a line terminator (\n or \r\n) was entered at the console, but that said line terminator was not included in the returned string.
