A little shell script to keep a Perl program under check.
When I’m working on a Perl program, every now and then I do some basic check to see if it compiles and its syntax is OK:
$ perl -c some-program.pl some-program.pl syntax OK
That’s because… well, sometimes a syntax error actually gets in:
$ perl -c some-other-program.pl Global symbol "$whatever" requires explicit package name... ... BEGIN not safe after errors--compilation aborted ...
It can be useful to keep a program under continuous check, in the sense that I want to figure out quickly when it breaks the compilation. The following script does exactly this in a Linux machine with inotifywait (part of inotify) installed:
Use it by passing the name of the Perl program you want to monitor:
$ perl-c-ontinuous whatever.pl /path/to/whatever.pl syntax OK ------------------- syntax error at /path/to/whatever.pl line 8, near "my " Global symbol "$original" requires explicit package name ... ... BEGIN not safe after errors--compilation aborted ... ------------------- /path/to/whatever.pl syntax OK -------------------
At each save, the
perl -c command is executed, and in case of syntax
errors… an error message is printed. Thanks to inotify this can
happen only upon saving the file, sparing system resources.
