Steps to refactor the Catalyst sample app BookDB

1. First, remove DefaultEnd and write an end method that will forward to either tt or Seamstress.
2. Reword the Actions one at a time starting with book/list

If I could interview Sebastian Riedel

1. Where do you work and what do you do?
2. What languages did you use widely before Perl
3. It seems like you jsut came out ofthe Blue with catalyst… how did you manage to absorb so much Conway and Cozens for so long and not publish on CPAN and why did you just explode out of nowhere

[15:22:01] <claco> what&#8217;s the official term for the development model used by catalyst and dbix; ya know the C3/NEXT load_components type stuff? [15:22:31] <omega> scary

A conversation with Sebastian Riedel on query strings and dispatch

[23:23:21] <metaperl> can the Regex attribute match the query string part also? I suppose I could write a simple app to check&#8230; [23:23:48] <@sri> no it doesn&#8217;t [23:24:22] <rconover> mod rewrite people [23:24:26] <metaperl> hmm so only path matching can occur with attributes&#8230; you do query string dispatching within a default sub by calling $c->forward as needed [23:24:36] <metaperl> rconover: what do you mean about mod_rewrite? [23:24:45] <@sri> aye [23:24:58] <metaperl> sri: what motivated that design decision? [23:25:07] <@sri> RES [23:25:09] <@sri> REST [23:25:31] <@sri> i like to think of paths as RESTish endpoints [23:25:44] <@sri> which take arguments in different forms [23:26:45] <metaperl> oh, a lot of websites have old <acronym title="Hot Tits Transport Pr0nocol (Ulrich Schwarz)">HTTP</acronym> calling conventions. that makes it harder to rework them in Catalyst [23:26:58] <@sri> example? [23:28:23] <metaperl> well, http://perlmonks.org/?node=Recently%20Active%20Threads [23:28:54] <metaperl> instead of perlmonks.org/recentlyActiveThreads [23:29:15] <@sri> why is that hard? [23:29:24] <@sri> have a default action to redispatch [23:29:46] <@sri> thats why we added default! [23:29:48] <@sri> :) [23:29:58] <metaperl> yeah, but then you end up with a default action with a huge if-then for all the different query string possibilities [23:30:13] <@sri> why? [23:30:21] <metaperl> I think there should be a FULL_URL option [23:30:29] <@sri> cat and perl are dynamic [23:30:35] <xover> mooorrrnning all [23:30:39] <@sri> just construct a action path and try [23:30:43] <metaperl> xover: good morning [23:31:07] <@sri> metaperl: it would be very easy to ass a RawRegex action type [23:31:16] <@sri> metaperl: but i don&#8217;t see a point yet [23:31:19] <@sri> add [23:31:30] <metaperl> sri: properly default is for unrecognized requests, it is serving double-duty by grokking Query strings [23:31:42] <@sri> no [23:31:48] <@sri> default is for redispatching [23:31:56] <jdv79> i skimmed jifty and it didn&#8217;t seem too appealing. did you look into it yet sri? [23:32:08] <@sri> the foo : Path is for unrecognzed [23:32:38] <@sri> jdv79: indeed, i sent some patches already :) [23:32:40] <rconover> you know having to use bind_param for blobs in sqllite sucks [23:33:12] <metaperl> &#8220;By leaving the Path definition empty, it will match on the namespace root.&#8221; [23:33:44] <metaperl> that is not the same as unrecognized is it? www.url.com/bad/path # wont match an empty Path [23:33:44] <@sri> jdv79: i see jifty as an interesting experiment, i want to see how much convention over freedom perl people are willing to accept [23:34:28] <@sri> metaperl: it is [23:34:43] <metaperl> sri: where is that documented? [23:34:49] <@sri> metaperl: everything behind the root is an argument [23:34:56] <metaperl> oh [23:34:56] <@sri> Intro.pod? [23:35:05] <@sri> for : Path [23:35:45] <@sri> the big difference between : Path and default is that Path can be local for Controllers [23:36:09] <@sri> while default always gets the whole request path in @_ [23:36:27] <@sri> so it&#8217;s made for redispatch [23:36:39] <jdv79> sri, i thought of it in a similar light. i&#8217;m just wondering if what jifty seems to do couldn&#8217;t be another layer onto of catalyst. [23:36:55] <@sri> jdv79: very easily [23:37:13] <@sri> jdv79: obra just didn&#8217;t grok cat, so he wrote his own framework [23:37:25] <metaperl> sri: you know that? [23:37:32] <@sri> what? [23:37:44] <metaperl> you his reason for writing jifty? [23:37:56] <rconover> jifty is getting good press [23:38:13] <@sri> we talked about it&#8230; [23:38:40] <@sri> top to bottom frameworks are very in atm [23:39:15] <@sri> only thing we are missing is some features in DBIC :( [23:39:48] <metaperl> brian d foy was at our local Perl Monger&#8217;s meeting yesterday. He said that <acronym title="Common Gateway Interface; Computer Generated Imagery">CGI</acronym>::Prototype is going to match the features of Catalyst - $clients are demanding it. Randal is saying the same&#8230; although draven&#8217;s journal entry (http://use.perl.org/~draven/journal/27613) shows a Merlyn wanting to ditch CGIP :) [23:40:23] <@sri> i think he will wrap CGIP around cat [23:41:01] <bda> http://video.google.com/videoplay?docid=-1032978311268695392 # Nice. [23:41:17] <@sri> what i really want is schema support in dbic :S [23:41:37] <metaperl> you mean like Alzabo reverse-engineering? [23:41:44] <@sri> naah [23:41:46] <@sri> sane [23:42:07] <@sri> think DBIx::Migration with perl code [23:42:12] <metaperl> Alzabo is a well-done product. Query formulation is irksome but the reverse-engineering and schema design tool are nicely robust
