7.4.2 ‘log()’ ¶

‘log()’ is the most commonly used message function in the package manager. It is used to pretty print messages with visual cues, so it is easier to read and understand for the users. It changes message output for each argument it receives (takes up to three arguments).

• If it takes a single argument, it prints a yellow leading arrow followed by colorless text.
• If it takes two arguments, it prints a yellow leading arrow followed by the first argument (colored blue), and then followed by colorless second argument.
• If it takes three arguments, instead of a yellow arrow, it prints the third argument in yellow, followed by the same two arguments as above.
