 John Ericson | fs.copyfile right? | 22:26:02 |
 emily | right, if you want to synthesize an include/nix in the build directory. though my actual proposal was just to move the files :) | 22:31:48 |
| John Ericson | emily: yes moving the files is what i have implemented today | 22:52:16 |
| John Ericson | but I sold Eelco on the compromise that you invented :) | 22:52:31 |

| John Ericson | hmm custom targets don't work with install_headers | 00:20:39 |
| John Ericson | I think I therefore want to symlnk the headers in the repo | 00:22:25 |
| John Ericson | Eelco: is that OK with you? | 00:22:31 |
 fzakaria | is there a good link to understand how the outPath is calculated for a drv ? | 02:48:57 |
| John Ericson | https://github.com/NixOS/nix/pull/12764 OK it's done (pending CI) | 05:50:17 |
| John Ericson | backport to avoid conflicts on other backports? not sure | 05:50:27 |
 Robert Hensing (roberth) | these new docs seem relevant https://nix.dev/manual/nix/development/store/derivation/index.html | 10:36:50 |
| Robert Hensing (roberth) | also its subpages | 10:36:59 |

https://github.com/NixOS/nix/pull/12764 OK it's done (pending CI) seems better to just ignore /libcmd/*.hh etc. rather than having an extra step for every new header | 12:17:07 |
|  sinan changed their profile picture. | 13:10:48 |
| John Ericson | emily: some libraries do have private headers, however | 14:59:42 |
| John Ericson | I would make more of that cleaning up the configuration headers too | 15:00:03 |
| John Ericson | * I would make more of them cleaning up the configuration headers too | 15:00:08 |
| emily | include-private/? :) | 15:02:27 |
| emily | or include/nix-private, avoids setting up another flag | 15:02:43 |
| John Ericson | hmm maybe | 15:04:52 |
| John Ericson | it is traditional to put the private headers with the source files, but it is also traditional to put the private headers and source files in something like src/ to distinguish from include/ | 15:06:47 |
| John Ericson | Another funny option is ....what happens if one .gitignores a .gitignore? :) | 15:07:27 |
| John Ericson | https://www.reddit.com/r/shittyprogramming/comments/auazfo/what_happens_if_you_put_gitignore_into_a/, oh dope! | 15:08:32 |
| John Ericson | emily: OK pushed a new version doing that | 15:35:35 |

| fzakaria | That's not bad but definitely a bit confusing; I think having to explain CA + input deriving makes it extra confusing.
I'm trying to better understand how inputDrvs (for input deriving) get replaced with some other hash recursively (hashModulo) | 16:20:53 |

I'm trying to better understand how inputDrvs (for input deriving) get replaced with some other hash recursively (hashModulo) I'm kind of in the process of implementing that for github.com/mschwaig/laut, except that the input hashes I generate for CA derivations are not based on the ATerm format (for now), but on a canonicalized version of the JSON representation of the derivation.
That implementation is also meant to be readable/understandable. | 16:48:48 |
