| Subject: | [wish] output useful for diff |
There may be more options lurking in this field, but for now I would be very happy to see an option to generate the output suitable for diff with output from another system. If I have the same script on two systems, and it works on one, but fails on the other, I want to compare the versions of the modules loaded. Devel::TraceUse is perfect for that, but in this specific case spews too much info.
As an example of what I used today to be able to compare:
$ perl -d:TraceUse /pro/po/bev/bin/sGBAb.pl -v2 lg1010161309 2>&1 |\
perl -ne's/, \S+ line \d+.*$//;if(s/^\s*\d+\.\s+//){push@x,$_;next}m/^(Modules used,|Possible pr)/ and print sort @x;print'
ideally that could be more like
$ perl -d:TraceUse=sorted_simple /pro/po/bev/bin/sGBAb.pl -v2 lg1010161309
Example of output change
$ perl -d:TraceUse=hidecore -MDP -we'DDumper \1'
\1
