Anyone know where I can get at the examples of Inline that were provided at the tech meeting? Against the good sense of others at the meeting, I'd like to try some simple regex compilations and compare their performance, using Inline. All of the inline.pm source code online seems to be targeted at static code, and I'd like to just reuse the examples you provided of dynamic code that md5-hashed itself, etc.
There is a link to the slide source at the bottom of http://www.vendian.org/mncharity/dir3/inline/ Please take the examples with a kilo of salt -- most were `talk in a few hours' write-only slide spewage ("having not been tested, it does not work", "having not been reviewed, it doesn't even try"). Md5 is used for symbol creation in two contexts. First, to help generate a unique function name for dynamically linking a specialized version of a function. One wants a uid which depends only on the rest of the code (ie, not a counter), so you don't give Inline needlessly different resulting code for it to cache-miss on. Second, to generate a simpler uid for some standin for code, with which to do your own caching (for instance, when the C code generation step is expensive). But this last is for debugability, not speed. For example, given strings which define regexps, and an expensive regexp to C code creation process, one might do both with something like my $re_id = md5sum($re); if(!$seen{$re_id}) { my $function_name = "mumble_${re_id}"; my $re_c_code = &compile_re_to_C_code(regexp => $re, function_name => $function_name); Inline->bind(C => $re_c_code); $seen{$re_id} = \&$function_name; } return $seen{$re_id}->(@_); Cheers, Mitchell Date: Fri, 15 Mar 2002 17:41:36 -0500 (EST) From: Michel J Lambert <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: [Boston.pm] Inline Examples from Tech Meeting Message-ID: <[EMAIL PROTECTED]> X-UIDL: +V[!!*Lc!!l/)#!fhS!!
