If you have your compiled templates cached on disk (with the COMPILE_DIR
option), you can try this command:
perl -ne "while ( /\\\$stash->get\\(\\[?'(\w+)'/g ) { print \
qq/\$1\\n/ }" /path/to/cached_template_file|sort -u
I just quickly whipped that up based on the idea that every variable
lookup would compile to a $stash->get() call. It seems to work pretty
well... but I'll admit it's not exactly graceful. :-) And if there are
references to variables that don't result in a $stash->get call, those
would be missed.
