Sys::OutPut 2.1

Sys::OutPut is a Perl module to help make output easier. SYNOPSIS usage Sys::OutPut; talk $fmtstr [, @args]; out $fmtstr [, @args]; put $fmtstr [, @args]; err $fmtstr [, @args]; debug $fmtstr [, @args]; $Sys::OutPut::quiet = $::quiet; $Sys::OutPut::debug = $::debug; These subroutines will make generating output to STDOUT and STDERR easier. All of the routines treat the $fmtstr argument as a printf format string, with @args as the format string arguments. The talk routine generates output to STDERR only if the variable $Sys::OutPut::quiet is non-null and non-zero. The out routine generates output to STDOUT, with a newline appended to <$fmtstr>, if it is not already terminated with one. The put routine generates output to STDOUT, without any additional trailing newline. The err routine generates output to STDERR, with a newline appended if needed. The debug routine generates output to STDERR only if the variable $Sys::OutPut::debug is non-null and non-zero, which is also returned as the result. This allows for convenient usages such as in the following example: sub foo { ... return if debug "Stopping now."; ... next if debug "Skipping further processing"; ... } If not defined by the user, the $Sys::OutPut::quiet and $Sys::OutPut::debug variables are initialized from their corresponding main variables $::quiet and $::debug, respectively, unless they are already defined..
