 Jan Tojnar | * perhaps you want to add arguments to partition, groupBy, … predicates to make it obvious they are functions | 23:48:21 |
| Jan Tojnar | you might also want to mention the full <set>.<attr> or <fallback> syntax | 23:51:49 |
| Jan Tojnar | string concatenation has wrong operator | 23:59:03 |

perhaps you want to add arguments to partition, groupBy, … predicates to make it obvious they are functions whoops, oversight, those were supposed to have arguments. fixed, thanks | 00:01:30 |

string concatenation has wrong operator fixed | 00:01:37 |

you might also want to mention the full <set>.<attr> or <fallback> syntax good point, will add that as well | 00:01:47 |

for flip, you mention two argument functions but there is technically no such thing I'm forgoing technical correctness in favour of accessibility, deliberately :) | 00:02:00 |
| joepie91 🏳️🌈 | (aside, the manual itself actually speaks of multiple arguments in a couple of places) | 00:03:20 |
| joepie91 🏳️🌈 | but yeah, the target demographic is "people without an FP background", and the scope is "enough information to find your way to the right utility for your usecase, and avoid particularly bad footguns, but no more than that" | 00:04:57 |
| joepie91 🏳️🌈 | for the semantic details, of which there are many, the manual is the correct place to look :p | 00:05:21 |
| joepie91 🏳️🌈 | same reason I generally don't specify return values for example | 00:05:57 |
| Jan Tojnar | I believe path should always be preferred to filterSource nowadays | 00:06:19 |
| joepie91 🏳️🌈 | wasn | 00:06:42 |
| joepie91 🏳️🌈 | * wasn't deprecated according to the manual, at least | 00:06:47 |
| joepie91 🏳️🌈 | it does have a caveat on what it is and isn't suitable for | 00:07:23 |
| Jan Tojnar | yeah, one probably would want to use the lib wrappers around it anyway | 00:08:27 |
| Jan Tojnar | or something like https://github.com/numtide/nix-filter | 00:08:38 |
| joepie91 🏳️🌈 | once flakes stabilize, I will probably update the cheatsheet to include such single-responsibility libraries | 00:09:21 |
| Jan Tojnar | typo in dirOf: director | 00:10:02 |
| joepie91 🏳️🌈 | whoops :D | 00:10:24 |
| Jan Tojnar | I would probably list stdenv.mkDerivation first | 00:13:00 |
| Jan Tojnar | if list the builtin at all | 00:13:13 |
| Jan Tojnar | I have already seen some beginners confused by it | 00:13:33 |
| Jan Tojnar | similarly the fetching section – people will want nixpkgs fetchers 99 % of the time | 00:14:17 |
| Jan Tojnar | * similarly the fetching section – people will want nixpkgs fetchers 90 % of the time | 00:14:35 |
| joepie91 🏳️🌈 | the nixpkgs fetchers! I knew I was forgetting something | 00:14:57 |
| joepie91 🏳️🌈 | swapped around the derivation functions and added a note to only use the builtin if nixpkgs is not available | 00:15:21 |
| joepie91 🏳️🌈 | will add the nixpkgs fetchers at some later time :p | 00:15:42 |
| joepie91 🏳️🌈 | I've left a FIXME in my sheet | 00:15:49 |
| Jan Tojnar | DocBook is spelt with capital B e.g. in literalDocBook | 00:16:19 |
