| vendethiel | I'll try to get back to irclog.perlgeek.de/6macros/2015-10-29 in the afternoon | 10:29 | |
| but for now, family stuff & | |||
| masak | :) | ||
| I tested the patch some more. it looks very promising. | 10:32 | ||
| I think its weakest point right now is Val::Object's stringification. | 10:33 | ||
| the obvious thing is that there's a `=>` in there, which is Perl 6, not 007 :) | |||
| but it also doesn't quote/escape its values properly | 10:36 | ||
| masak notices something odd with the way this is factored for arrays, and goes to fix | 10:38 | ||
| ok, just pushed github.com/masak/007/commit/745db5...b0526f9d0f which will surely help you make a better stringification for objects by exposing the right things | 10:59 | ||

| masak | Q::Property does Q but not Q::Literal. literals are only for things that can occur in expressions. | 14:20 | |
| pushed yet another small commit that makes quoted stringification easier. | 14:48 | ||
| vendethiel: token term:object { '{' ~ '}' <property>* % [\\h* ',' \\h*] } -- why only horizontal whitespace? surely an object can be written over several lines? | 14:55 | ||
| I think both of those should be <.ws> | |||
| ... | 15:11 | ||
| so, I was thinking | |||
| quasi @ Q::Trait { ... } means "put the parser in a state so that it's expecting a trait", right? | |||
| and the default `quasi { ... }` means something like `quasi @ Q::Expr { ... }` (because that's what macros return, because that's what both listop calls and operators are) | 15:12 | ||
| if that's so, then how come we can write arbitrary statementlists inside of the quasi? | 15:13 | ||
| something doesn't add up there. | |||
| this doesn't happen in Lisp because "everything's an expression/AST fragment" | 15:20 | ||
| in Perl 6, we have to agree with the parser what it is we're parsing | 15:21 | ||
| vendethiel: it seems `{bar() {}}` parses as a valid object literal, but `{bar() {} }` doesn't right now | 15:59 | ||

| vendethiel | haha | 16:25 | |
| also, you linked a fork of the riddley project. any reason? | 16:26 | ||
| github.com/ztellman/riddley seems more up-to-date | |||
