 rosssmyth | Yeah my latest project has a lexer that is just a copy of Rustc's lexer with my tokens in it, ungrammar for the cst data structures, and then hand-rolled parser. | 16:29:58 |
| rosssmyth | Logos is cool though | 16:30:09 |
| rosssmyth | Used it before | 16:30:14 |
| rosssmyth | The thing about parsing is that perf doesn't really matter that much, it's such a small amount of time unless you really mess it up. Better to focus on making it have really good errors | 16:32:12 |

| piegames | Due to unfortunate design decisions made (or rather, not made) back when I was in Kindergarten, parsing is on the critical path for evaluation time | 16:35:23 |
| rosssmyth | amazing | 16:35:33 |
| rosssmyth | If you want the highest performance possible, larlpop will be hard to beat. But recovery is bad so it would be difficult to get good diagnostics out of it. | 16:43:50 |
 helle (just a stray cat girl) | what is the process if we need to do a backport of a patch (or other proposals of how to handle this one)
this as nixpkgs mdbook 0.5.0 update depends on https://gerrit.lix.systems/c/lix/+/4653 being in
see https://github.com/NixOS/nixpkgs/pull/462777#issuecomment-3637993347 & https://github.com/NixOS/nixpkgs/pull/467009 | 16:50:39 |

narrator voice indeed it is really messed up something something C++ parsing… | 17:18:05 |
| piegames | that too, but that's not even what I meant | 17:18:20 |

Due to unfortunate design decisions made (or rather, not made) back when I was in Kindergarten, parsing is on the critical path for evaluation time Is that because parsing is so unbearably slow, or is there a more cursed reason? | 17:18:25 |
