| deoac | The docs describe `.fmt` for type/Cool: "[fmt is the] equivalent to calling sprintf with $format as format and the invocant as the second argument." | 02:00 | |
| m: printf('There are %d %s in a %s', 52, 'cards', 'deck') | 02:01 | ||
| camelia | There are 52 cards in a deck | ||
| deoac | m: (52, 'cards', 'deck').fmt('There are %d %s in a %s') | ||
| camelia | Your printf-style directives specify 3 arguments, but 1 argument was supplied in block <unit> at <tmp> line 1 |
||
| deoac | Is the documentation inaccurate? | 02:02 | |

| habere-et-disper | Why can I write : | 20:46 | |
| m: say <Hello, World!>.antipairs.Hash{ 'World!' } | |||
| camelia | 1 | ||
| habere-et-disper | But not as a method chain over 2 lines ? | ||
| m: (<Hello, World!>.antipairs | 20:56 | ||
| camelia | ===SORRY!=== Error while compiling <tmp> Unable to parse expression in parenthesized expression; couldn't find final ')' (corresponding starter was at line 1) at <tmp>:1 ------> (<Hello, World!>.antipairs⏏<EOL> expecting any… |
||
| habere-et-disper | .Hash{ 'World!' }).raku | ||
| How do I ask Camelia to take a line break ? | 20:57 | ||
| lizmat | m: say "foo"; say "bar" | 22:28 | |
| camelia | foo bar |
||
| lizmat | habere-et-disper: ^^^ add a  to your expression, and camelia will change that to a \n in your code | 22:29 | |
| habere-et-disper | So like : | 22:30 | |
| m: m: <Hello, World!>.antipairs.Hash{ 'World!' } | |||
| camelia | ===SORRY!=== Error while compiling <tmp> Unexpected block in infix position (missing statement control word before the expression?) at <tmp>:2 ------> .Hash⏏{ 'World!' } expecting any of: infix infix stop… |
||
| habere-et-disper | Is that expected behaviour ? I was surprised. | 22:32 | |
| lizmat | habere-et-disper: looks like you found a grammar bug | 22:34 | |
| habere-et-disper | Okay -- thanks. | ||
| lizmat | please file an issue for it :-) | 22:35 | |
| grammar bugs have become very rare the past years :-) | 22:36 | ||
| habere-et-disper | Sure -- in rakudo/rakduo ? | 22:42 | |
| lizmat | yes, please | 22:50 | |
