Hi, Monks. . . This seems like a FAQ but I'll be doggoned if I could find it anywhere. I have a script that will be taking text from a configuration file which will then be executed remotely (or locally) as a perl snippet. How can I syntax check it? eval would compile it and
run it (though the stages that it completes depends on the syntax used - either of
eval BLOCK or
eval EXPR). E.g.:
my $str = <<'CODEIMPORT'; # this code block would be dynamic
print "Don't run me!\n";
prnt 'Just check me for errors\n":
CODEIMPORT
# eval $str; # gives a run-time error
eval { $str; }; # compiles (?) - but does not check syntax
# I just want to check for syntax -
# it will evaluated later and in a new/different context
# (e.g., passed to a different script)
Here's a
discussion from the Original Monks regarding eval in this context.
Am I overlooking the obvious? I know I could shell out to
perl -wc but it seems to be an overkill since I really just want to check that one little code block. I thought the B: or O: modules might help but I can't figure out how they might. Ideas?
