[This seems to be a very useful module for those who try to minimize the memory usage, by finding out irrelevant modules loaded without your consent :)
Michael G Schwern said: Module::Use appears to use the "let's sniff through %INC" approach, which is clever and useful and sometimes more accurate, but requires you actually run the program/module. Module::Info uses the backend compiler. It compiles the module but doesn't not run it. It finds all 'use' and 'require' statements using the opcode tree. As a result its perfectly accurate, except it can't see things inside an eval(). Module::Use can. The other nice thing Module::Info does (err, will do) is tell you one what line and file module was used. Useful for refactoring and figuring out what uses what. ] Michael G Schwern has then announced at [EMAIL PROTECTED]: [I've fixed the message as Michael, has just released 0.09, the original announcement was for 0.08.] This is the Egg Shen release [1] of Module::Info. http://www.pobox.com/~schwern/src/Module-Info-0.09.tar.gz This release adds modules_used(). Tells you all the modules and files required or used by the module in question using the backend compiler. As such its more reliable than a regex-based one. modules_used my @used = $module->modules_used; Returns a list of all modules and files which may be "use"'d or "require"'d by this module. NOTE These modules may be conditionally loaded, can't tell. Also can't find modules which might be used inside an "eval". I had to do some severe cargo-cultery from B::Deparse to make this work. If anyone's curious they can look at B::Module::Info, but I'd recommend against it. This method simply returns a list of all the modules used. I plan on providing another method which provides additional info such as where each is used, how many times and if it was required as a bareword or not (ie. "require Foo" vs "require 'Foo.pm'"). I've got all that information internally, just need to put an interface on it. That should make the refactoring folks happy. 0.08 Mon Dec 10 14:24:56 EST 2001 * Implemented modules_used() - Fixed a little bug in walkoptree_filtered() and $B::Utils::file/line 0.07 Mon Dec 10 11:09:40 EST 2001 * Implemented subroutines(). Need help getting modules_used() done. - Fixed up $B::Utils::file/line handling in B::Utils. - Fixed a little bug in is_core involving cannonical paths. I forget who gave me the patch! -- _____________________________________________________________________ Stas Bekman JAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide http://perl.apache.org/guide mailto:[EMAIL PROTECTED] http://ticketmaster.com http://apacheweek.com http://singlesheaven.com http://perl.apache.org http://perlmonth.com/
