02:38 jeffreykegler An interesting Marpa-related Q&A on stackoverflow: http://stackoverflow.com/questions/27655176/one-character-parenthesis-matching

17:38 jeffreykegler A thought: I am still working on the idea of piece-wise parsing -- producing partial parses, then piecing them together ...
17:39 jeffreykegler and it occurred to me that the ability to produce "partial parse trees" or "parse trees so far" has another use ...
17:39 jeffreykegler error tracing.
17:41 jeffreykegler That is, you can, when the parse ends due to an error, produce a tree showing what was parsed so far.  This might be a much easier (more intuitive) way to find problems than examining progress reports.
17:42 jeffreykegler Any thoughts?
17:42 jeffreykegler Would it be useful if, when you have an error, you could say to Marpa: "Show me the tree"?

19:04 Aria YES. I've been thinking about this a lot, too.
20:12 ronsavage1 Some really scary syntax where Pg meets JSON: http://www.postgresql.org/docs/9.4/static/functions-json.html
20:15 Aria "Show me the tree" or "show me the trees" would be super useful for errors. I wonder about automating a multi-tier grammar from a single BNF -- are there ways to preserve useful semantics that way?
