02:17 idiosyncrat ronsavage: re https://irclog.perlgeek.de/marpa/2017-04-01#i_14362126 --
02:17 idiosyncrat Another alternative is "Jeffrey Kegler is creating Marpa" -- some Patreon creators take that approach.  *None* of them add an article, at least that I've seen so far.
03:23 idiosyncrat OK.  A few of them add an article.
03:29 ronsavage levelup: You can use multiple lines with the same LHS:
03:29 ronsavage statement_terminator::= semicolon_literal
03:29 ronsavage statement_terminator::=
03:29 ronsavage In this case the 2nd is null, but ignore that.
03:29 ronsavage Likewise for L0 items:
03:29 ronsavage :lexeme~ close_bracketpause => beforeevent => close_bracket
03:29 ronsavage close_bracket~ ']'
03:29 ronsavage close_bracket~ '];'
03:30 ronsavage By ignore, I mean ignore the fact that it's null and just add you own grammar.
03:31 ronsavage Alternately, you could use:
03:31 ronsavage subgraph_sequence::= subgraph_sub_and_id
03:31 ronsavage | subgraph_sub_no_id
03:31 ronsavage | subgraph_no_sub_no_id
03:31 ronsavage This gives Marpa 3 ways to expect a subgraph_sequence.
03:54 idiosyncrat ronsavage: IIRC levelup's question was how to convert jdurand's grammar to LALR/yacc
03:55 idiosyncrat Since LALR is a very small subset of BNF/context-free, that is not in general possible, and is not possible in many practical cases.

04:49 idiosyncrat ronsavage: Let me know what you think is best re Patreon title.
04:50 idiosyncrat Good night!

05:50 ronsavage JK: Re Patreon. How about Jeffrey Kegler Author of Marpa/.... Since your name is in bold, the lack of a colon just after 'Kegler' should be ok.
05:51 ronsavage JK: Re http://irclog.perlgeek.de/marpa/2017-04-02#i_14362721. Oh.
06:13 idiosyncrat joined #marpa
06:15 idiosyncrat ronsavage: The point is Patreon will create a title of the form "X is creating Y", where it uses my name as "X", and I can supply the text for Y.
06:15 idiosyncrat So "
06:16 idiosyncrat So "Jeffrey Kegler Author of Marpa" is just not something their format allows.
06:16 idiosyncrat I need an Y that makes sense when stuck into the above formula.
06:17 idiosyncrat The Y also gets stuck into the phrase "Creating Y" at various points.
06:17 idiosyncrat So if Y == "Marpa", then I get "Jeffrey Kegler is creating Marpa".

22:15 ronsavage JK: Re http://irclog.perlgeek.de/marpa/2017-04-02#i_14363066. Yep, get it. Perhaps you should volunteer to re-write their formula using Marpa. ROFL.
22:17 ronsavage Now, will you be putting a link to Patreon on your Marpa or personal pages? Should I add one to my Marpa page?
23:26 idiosyncrat joined #marpa
23:26 idiosyncrat ronsavage: re https://irclog.perlgeek.de/marpa/2017-04-02#i_14365436
23:26 idiosyncrat Yes, I'll be adding it to my Marpa page.
23:26 idiosyncrat And yes, please add it to the semi-official Marpa page.
23:27 VsyachePuz joined #marpa
23:27 idiosyncrat ronsavage: Note I've promoted your page from "unofficial" to "semi-official".
23:29 idiosyncrat lucs: I think best *NOT* to add it to the IRC topic line.
23:30 lucs Okay
23:30 idiosyncrat My model is that my Patreon contributors will not be the kind of "impulse" contributors most accounts get, but instead will be people who know a lot about Marpa, or who are using it.
23:33 idiosyncrat So I assume that contributors will be people who've spent some time on the official or semi-official pages.
