| jaguart | Ok - so I've skirmished with rakudo-pkg on Debian - and ended up being reminded of how much implicit knowlege is not actually written down. I'm getting the weird impression that zef-install has to be run for *every* user? and then that *zef install module* also has to be run for _every_ user including root? | 02:28 | |
| there is a hint about #inst at the end of the zef readme, or maybe DefaultCUR default value of auto... and directory permissions in /opt/rakudo-pkg | 02:43 | ||
| whew - it is possible to have site modules with a bit of permissioning and tweaking of rakudo-pkg install scripts | 03:48 | ||
| Mason | is there a way to do this? | 05:55 | |
| ```raku | |||
| given $foo { | |||
| when /'keyword '(\w+)/ -> $match { | |||
| $match.say; | |||
| } | |||
| } | |||
| ``` | |||
| jaguart | m: given "one keyword too many" { when / keyword \s+ (\w+) { $0.say } / {} } | 06:28 | |
| camelia | ｢too｣ | ||
| jaguart | if you actually want to do something interesting in the given block you can: | 06:52 | |
| m: given "red keyword one green keyword two blue" { when m:g/ keyword \s+ (\w+) {make($0.Str)} / { $/.map({say .made}) } } | |||
| camelia | one two |

| Mason | $0 was what I was looking for I think | 10:56 | |
| Nemokosch | I don't understand the question and the answer either xd | 11:09 | |
| just to make sure everyone is on the same page | 11:10 | ||
| $/ is the match object | |||
| $0, $1, $2 etc are the capture groups of that match object, i.e $/[0], $/[1] etc | |||
| it's possible to execute code straight from regex because code blocks still count, and apparently those code blocks can already access the forming match object | 11:12 | ||
| make is for assigning data to a certain match, usually for parsing purposes, and .made is to access the assigned data (I think .ast also works for the same purpose) | 11:13 | ||
| for convenience, you can also set the limits of the whole match object with <( and )> respectively | 11:14 | ||
| oh and a disclaimer: Raku regexes are still slow, one could say too slow for mass manipulation | 11:16 | ||

| ToddAndMargo | When I am in a module (pm6), is there one of those fancy system variables that will tell me the name of calling (pl6) program? | 17:08 | |
| jaguart | $*PROGRAM-NAME | 17:09 | |
| ToddAndMargo | thankyouthankyouthankyou!! | ||
| I am getting back "-e.bat" raku -e "use lib '.'; use NativeWinUtils :RunCmd; say RunCmd(Q[ls]);" | 17:26 | ||
| I put the .bat onto it. so "-e" | |||
| Nemokosch | that's your calling program indeed - inline Raku using the -e option | 17:28 | |

| ToddAndMargo | I get it now. Duh! | 17:30 | |
| any reason why "print" does not show up on the screen from inside a module? | 17:32 | ||
