Perl supports a -x command line option that was originally intended for
saved emails containing a perl script. When perl is invoked with the -x
option, it scans the file for a #!perl line and treats that as the first
line of the script. The related #line option allows the line number to
be reset so perl can report line numbers from an arbitrary offset in the
file.
In our environment, we frequently need to source shell configuration
files before starting a perl script. The -x functionality allows us to
combine the setup shell script and the perl script in a single file; we
call this a shell springboard.
Because PPI doesn't understand the -x option or the #!perl
functionality, when perlcritic is run on a script using a ksh
springboard, the script generally gets confused and starts reporting
rather inaccurate messages. For example, in the attached script,
perlcritic reports "code before use strict" and "mismatched operator"
where it really complains about the ksh code leading up to the perl script.
The request: make PPI and perlcritic support this, either through some
sort of -x option or by recognizing the #!perl line.
