16:40 CQ https://www.quora.com/unanswered/What-are-the-di​fferences-between-Marpa-and-the-Perl-6-grammars ...might be worth answering, was one of the first hits I saw when googling marpa vs perl6
17:24 gabiruh joined #marpa
17:27 gabiruh hey, guys
17:27 gabiruh how can I make Marpa act like Regexp::Grammars?
17:28 gabiruh like.. returning a hashref-based tree
17:30 gabiruh I want to feed it with a grammar, a string to parse and I want an AST back
17:37 CQ gabiruh: if noone is here, wait a while, or read the irc log tomorrow, they usually answer
17:38 gabiruh CQ: ok
21:10 ronsavage joined #marpa
21:23 ronsavage gabiruh: From the Marpa home page you'll see there are many modules to study: http://savage.net.au/Marpa.html#Perl_Packages. In particular see MarpaX::Languages::SVG::Parser and X500::DN::Marpa where I use actions to return hashes. But in most modules I save the data in a stack whose elements are trees managed by Tree or Tree::DAG_Node.
21:24 ronsavage gabiruh: IOW You can any data structure. It's really a matter of seeing how other authors have done it and choosing what best suits your application.
21:26 ronsavage CQ: See https://jeffreykegler.github.io/Ocean-of-Awa​reness-blog/individual/2015/12/topdown.html. Down near the end Jeffrey lists some things Marpa can do and which Perl6 can't.
21:31 gabiruh ronsavage: thank you!
21:31 ronsavage CQ: I decided not to register with quora.com because they want - if I log in via Google - access to my contact among other things, and my contacts are none of their business.
21:32 ronsavage CQ: 'contact' -> 'contacts'.

22:10 idiosyncrat_ Re: Quora
22:12 idiosyncrat_ Quora requires you give an account, not only to answer questions (which is reasonable), but even to look at answers.
22:13 idiosyncrat_ Note that they make the questions available to all, but to actually see an answer you have to have an account, and an account ...
22:13 idiosyncrat_ requires you to give them email and name.
22:13 idiosyncrat_ This IMHO is leveraging the questions as clickbait.
22:15 idiosyncrat_ To be clear, Quora has every right to try to build a profitable business and to attract customers, but I do not see why volunteers from the Marpa community would want to provide answers which Quora makes its own IP and puts behind a paywall.
