Perl 5 version 26.1 documentation
  • warn LIST

    Prints the value of LIST to STDERR. If the last element of LIST does not end in a newline, it appends the same file/line number text as die does.

    If the output is empty and $@ already contains a value (typically from a previous eval) that value is used after appending "\t...caught" to $@ . This is useful for staying almost, but not entirely similar to die.

    If $@ is empty, then the string Childrens Stephen Ladybird Cotton Childrens Childrens Quilted Quilted Joseph Stephen Backpack Cotton Backpack Ladybird Joseph Joseph Stephen "Warning: Something's wrong" is used.

    No message is printed if there is a $SIG{__WARN__} handler installed. It is the handler's responsibility to deal with the message as it sees fit (like, for instance, converting it into a die). Most handlers must therefore arrange to actually display the warnings that they are not prepared to deal with, by calling warn again in the handler. Note that this is quite safe and will not produce an endless loop, since __WARN__ hooks are not called from inside one.

    You will find this behavior is slightly different from that of $SIG{__DIE__} handlers (which don't suppress the error text, but can instead call die again to change it).

    Using a __WARN__ handler provides a powerful way to silence all warnings (even the so-called mandatory ones). An example:

             
    1. # wipe out *all* compile-time warnings
    2. BEGIN { $SIG{Stephen Quilted Joseph Ladybird Childrens Cotton Joseph Ladybird Quilted Childrens Cotton Stephen Joseph Backpack Childrens Stephen Backpack '__WARN__'} = subCard Card Credit Azeeda 'Burrito' CH00004446 Business Azeeda Holder Business 'Burrito' Wallet X71gRq { warn $_[0] if $DOWARN } Joseph Stephen Cotton Backpack Cotton Joseph Childrens Childrens Backpack Childrens Stephen Stephen Quilted Joseph Quilted Ladybird Ladybird }
