 martin | How can I build only libexpr with meson? | 10:42:17 |
 roberth | martin: with the flake, nix build .#default.libs.nix-expr. For development, instead of meson compile run ninja src/libexpr/libnixexpr.so or meson test nix-expr-tests (runs unit tests, but most of our coverage is in the functional test suite, i.e. meson test) | 12:00:57 |

 tomberek | Double-checking: multiple-outputs for impure-derivations is not expected to work at this time?
error: derivation '/nix/store/h8vc7ifz5lx8zqgmny0jsdmcyf8123ns-thing.drv' doesn't have expected output 'second' (derivation-goal.cc/resolvedFinished,realisation)

 Winter | fwiw tomberek et al, i'm going to get to #13501 soon -- the issue is just a tad more haunted than i originally thought: the fix is still sane, though! i just want to get a better explanation in-tree. | 06:29:56 |

 WeetHet | Now that infra supports lockable tarballs for channel releases, what do you think about adding a channel:name flakeref pointing to channels.nixos.org/name/nixexprs.tar.xz?
Is it too much coupling?
| 20:09:03 |
 leona | I (not part of the nix team nor associated with nix development) wouldn't like the name "channel:" for this, as the concept of a channel is far greater than Nixpkgs and therefore anything channel.nixos.org offers | 20:39:51 |

 dramforever | even though it's debatable whether it would be good to add it to flakes, there is precedence for e.g. channel: urls already being that | 01:42:03 |

nix-instantiate channel:nixpkgs-unstable hello --log-format multiline

 fzakaria | Whose familiar with SourceAccessor in CppNix ?
We were seeing divergent failures for missing files; I was seeing "FileNotFoundError" and Shahar "Dawn" Or (mightyiam) was seeing "SysError" (although not in unit tests).
We've rebased and it's gone away but it's bugging me not knowing the difference.
