| coleman | what's LTM mean in this context? | 00:23 | |
| guifa | patrickb: here's a way | 00:52 | |
| my @routines = <abc defg hijklm>; my %routines := @routines.Set; my token routine { <!ww> $<name>=[.*?] <!ww> <?{ %routines{~$<name>} }> }; say 'asd abc woek' ~~ &routine | 00:53 | ||
| evalable6 | ｢abc｣ name => ｢abc｣ |
||
| guifa | basically, you grab what COULD be a match -- once -- and then check it in a set which is O(1), much better than O(n) that is a bare @routines | 00:54 | |
| lizmat / ab5tract : AIUI {} breaks LTM for the token itself, @routines is like inserting the a|b|c in a [ ], so the LTM still has to happen for that particular group | 00:55 | ||
| ab5tract | That’s what I figured | ||
| guifa | oooh -- I wonder if it would be possible to optimize this for at compile time | 00:56 | |
|

| guifa | like if you have @foo = <abc ade foo fooo>, you could do O(@foo), capture that, analyze it at compile time (so must be known then) and rewrite it as [ a [bc|de] | foo o? ] | 00:57 | |
| obviously, can only do it for compile time stuff, but it'd be a pretty straight forward algorithm | 00:59 | ||
| coleman: LTM is longest token matching. A old gotcha in regex of yore was to do something like (go | going | gone) and try to match it on 'He's going to the store'. | 01:00 | ||
| It'll actually match go first, because it's the first alternation | 01:01 | ||
| so most of the time you'd need to sort it. LTM basically says "we'll try each alternation, and the one that's the longest wins first" | 01:02 | ||

| patrickb | Thinking a bit on this, I think the problem is not the LTM. I'm pretty sure Raku is smart enough to sort the LTM alternatives and create a decent NFA. Instead the issue probably is, that interpolating that variable means the regex is dynamic and it will have to recreate the thing from scratch on every use. | 08:58 | |

| patrickb | I didn't verify yet (by doing some timing tests), but I'll do so. My guess is, that the idea to match blindly and check afterwards should work (but not as optimal as could be) and the best way would be to just type out the alternatives in the token literally and not do any interpolation at all. | 09:00 | |

| jdv | coleman: Longest Token Match | 11:33 | |
| tbrowder | i have a question on using rak in a program. as i understand from reading its docs, the first arg must be either a pattern to search for in files or a Callable. | 11:54 | |
| my question is: how do i construct a Callable that says "look at all files that meet this test"? | 11:56 | ||
| rak has very many ways to say that with with named args, so i need a Callable that says "pass me on to the named args" | 11:57 | ||
| in debian using find i would start with "find /" and press on | 11:58 | ||
| but i haven't figured out how to do that with rak | 12:02 | ||
| lizmat | '{ .meets-the-test }' | 12:08 | |
| librasteve | just a thought… this may be an opportunity for rakuAST … ie inspection of the AST produced by that token/alternation may be quite inefficient and maybe you could cut out unneeded actions? | 12:19 | |

| tbrowder | lizmat: it looks like rak is inspecting file contents even with {.meets-the-test}. is there a way to completely ignore inspecting the contents? | 13:15 | |
| lizmat | did you specify --find ? | 13:22 | |
| tbrowder | no | 13:23 | |
| lizmat | rak --find '{ $_ contains an IO::Path object of each selected file }' | ||
| tbrowder | hm, i added .find and now get errors about meets-the-test doesn't work on path object | 13:26 | |
| lizmat | --find you mean? | ||
| we should probably move this to #raku-rak or to an issue | 13:27 | ||
| tbrowder | i need to join that channel... | 13:28 | |

It's redundant because `rakudo.org/` has a huge and prominent "Download" button in the center. So linking to `rakudo.org/` is sufficient. Also linking to subpages of other sites is a bit of a bad practice. |

| [Coke] wonders if anyone else here has to do "CPE" training for their job (continuing professional education) (mainly a requirement any place I've worked with accountants, even if you're not an accountant yourself) | 19:44 | ||
| coleman | Yes, for American Express, which I was a contractor at for a while | 19:48 | |
| Lots of stuff about financial crimes that wouldn't come up most likely, but compliance demands that all employees complete training every year | 19:49 | ||
