in reply to Redefining Imported Subs: of scope and no

Don't mess with say, it will byte you or a later maintainer of this code.

Instead, (1) define sub debug {...}; with a plain old if inside. (2) Replace all occurences of say with debug(). (3) Replace those say's that aren't really for debugging back again. (4) Re-run your tests to see if anything got lost.

You can then consider moving debug() to a separate module for re-use, or switch to Log4perl altogether as other monk suggests here, or even write a debug_off() sub that replaces debug() on the fly. But at least it's not like "Hey, say() prints nothing! Our perl interpreter must be broken!"

[LanX]: probably I need to teach the app to restart after C-c Kill
[Corion]: LanX: Maybe have an infinite-loop cmd file? Much easier than trying to manage that from within Perl IMO
[Corion]: Alternatively, relaunch the application from cron (or a Windows cron) every minute
[LanX]: will try infinite loop ...
[Corion]: :START ... goto START
[LanX]: oh .bat you mean?
[LanX]: obscure cult ...
[Corion]: LanX: cmd.exe is just another way to launch Perl
[LanX]: I know its a cult... and I repent it every time
[LanX]: But cygwin comes with path problems and powershell requires too much learning for me
