🦋 Welcome to the IRC channel of the core developers of the Raku Programming Language (raku.org #rakulang). This channel is logged for the purpose of history keeping about its development | evalbot usage: 'm: say 3;' or /msg camelia m: ... | log inspection situation still under development | For MoarVM see #moarvm Set by lizmat on 22 May 2021. |

ugexe | call .loaded on a cur | 00:22 | |
Xliff | ugexe: How can I get a CUR by name? | 00:23 | |
ugexe | m: say CompUnit::RepositoryRegistry.^methods | 00:25 | |
camelia | (repository-for-spec setup-repositories use-repository repository-for-name register-name name-for-repository file-for-spec run-script head resolve-unknown-repos resolve_repossession_conflicts BUILDALL) | ||
Xliff | use ICal::GLib::Raw::Definitions; my $a = try ::("ICal::GLib::Raw::Definitions"); say $a.HOW.^name unless $a ~~ Failure | 00:26 | |
Tells me 'Perl6::Metamodel::PackageHOW' | |||
Without the use statement, I get (Any) not failure, so | 00:28 | ||
What's the best way to test for Any? I thought "$a =:= Nil" worked. | 00:29 | ||
moon-child | Any ~~ $a? | ||
m: my $x := Nil; say Any ~~ $x # hmm, maybe not quite | 00:31 | ||
camelia | False | ||
Xliff | Huh! Works for my intended use-case... | ||
moon-child | oh, Nil ~~ Any, so you can use Nil ~~ $a | 00:33 | |
Xliff | Odd. Why the reversed operands? | 00:35 | |
moon-child | well, $x ~~ Any is almost invariably true... | 00:36 | |
$x ~~ Nil is true only if $x is actually Nil, but not if it's a type object | 00:38 | ||
Also my Any ~~ apparently doesn't work correctly either | |||
m: my $x; my Int $y; say Any ~~ $x; say Any ~~ $y #same with Nil ~~ | |||
camelia | True False |
||
ugexe | Int $y does not accept Any | 00:39 | |
i generally try to read $x ~~ $y as "does $y ACCEPT $x" | 00:40 | ||

Xliff | lizmat: I know you are working on the weekly, but do you know if the RakuAST node for "do" blocks has been created? | 16:24 | |
lizmat: At your leisure. | |||
lizmat | Xliff: looks like there are passing tests for it: github.com/rakudo/rakudo/blob/raku...ixes.t#L29 | 16:26 | |
so I'd say: yes | |||

[Coke] | to build a raku with rakuast, just checkout the branch and go? Any env vars to set or config options to pass? | 18:41 | |

raydiak | I just built it the normal way, seems to run all the ast tests just fine | 19:14 | |
[Coke] | ok | 19:35 | |
MasterDuke | don't you have to set an env variable at runtime to actually use the new frontend? | 19:38 | |

rakudo/rakuast: f7244fc1e0 | (Jonathan Worthington)++ | src/Raku/ast/regex.rakumod Coalesce sequences of regex literals When we have `/st/`, the compiler frontend currently produces two RakuAST::Regex::Literal nodes. These were individually compiled also, which breaks matching against the ligature st (with the appropriate options set). Coalesce these as part of the compilation from RakuAST to QAST, meaning that the same job doesn't have to be done by all those synthetically constructing RakuAST in order to get correct matching. |

raydiak | quite possibly. I only ran the tests in 12-rakuast, which build RakuAST nodes explicitly. it could still be using the old frontend and run those tests | 22:55 | |
looks like yes, to enable the new frontend you need RAKUDO_RAKUAST as stated in github.com/rakudo/rakudo/blob/raku.../README.md and at github.com/rakudo/rakudo/blob/raku...in.nqp#L18 | 22:58 | ||
when running. I don't see any sign that it matters for building | 23:00 |
