Sets the variable $diagnostics::PRETTY
to true
Prints the perldiag manpage introduction, then any diagnostic messages
As a pragma:
use diagnostics [-verbose]
enables the use of diagnostics in your program (and enables
Perl’s -w flag). Compilation is then subject to
the enhanced diagnostics, which are issued to STDERR. Set the
diagnostics::PRETTY
variable in a
BEGIN block to provide nicer escape sequences for pagers, so your
output looks better. The -verbose
option prints the perldiag manpage
introduction, then any diagnostic messages. Functions are:
enable
Turns diagnostics on at runtime
disable
Turns diagnostics off at runtime
