 goldstein | hi! I’m trying to add a functional test for my patch, but a couple of those seem to be failing even on main, e.g. tarball (fails with line 37: TMPDIR: unbound variable) and bash-profile (fails with ../../scripts/nix-profile.sh.in: No such file or directory). do I need to do something special to set them up other than just build install test?.. | 13:18:34 |
 just1602 | @raitobezarius:matrix.org: do you think you could kick CI on CL 4761? | 13:22:19 |
 piegames | Charles: I've heard you have opinions on Rust parser libraries? | 14:36:01 |
| piegames | Asking for the eventual Lix parser rewrite | 14:36:12 |
| piegames | Main criteria are maximum performance and good error handling, with support for multiple errors but no full-blown error recovery | 14:36:53 |

That is sadly a known bug, you must have it set in your shell env, though dont remember to what value...
Something something functional2 will fix this | 14:56:11 |

Something something functional2 will fix this okay, thanks. it passes in CI, so ig I’ll just ignore it for now | 14:56:49 |

 Charles | i like parser combinators, chumsky is neat but its cool features (zero copy parsing) are only on unstable releases and its development has been slow lately, winnow is also good (i haven't actually tried winnow, but i have tried nom, which is what it forked from; winnow mainly just adds some extra stuff like span tracking for errors) | 15:21:47 |
| Charles | there's a somewhat related library called ariadne which can generate very pretty error messages for parsing errors | 15:23:04 |

But also didn't use it myself | 15:25:14 |
 kloenk | also do quite a bit of parser dev currently for a project :)
decided against chumsky as I also wanted to have the possibility to add a lsp and formatter later. Currently using ariadne as well for error reporting. did consider looking at miette (miette has a magic flag to create screen reader friendly output) | 15:32:11 |
| piegames | Yeah I've heard that of miette, which is really nice | 15:32:43 |
| piegames | Though on a first glance the ariadne API seems a lot simpler | 15:32:55 |
| Charles | hmm what about chumsky precludes its use for LSPs and formatters? | 15:34:30 |
| kloenk | my want for a lossless syntax tree. Chumsky apparently can somehow integrate into rowan, but found it so painful that I decided to use logos and do it with only logos | 15:35:09 |
| Charles | oh right yeah i forgot to mention rowan exists | 15:35:29 |
| kloenk | yeah that is true. and apparently they have a todo for screen reader output so maybe at some point | 15:35:52 |
