@infinisil:matrix.orginfinisil ryantm: Oh and nix-build pkgs/top-level/release.nix -A manual is for the Nixpkgs manual 05:12:08
@ryantm:matrix.orgryantmThat one would be a more fair comparison since I render the entire nixpkgs manual (also with a search index)05:13:21

@ryantm:matrix.orgryantmVery similar times!05:15:03
@ryantm:matrix.orgryantmGood on you making it that fast with Python :)05:16:48
@ryantm:matrix.orgryantmLooks like it builds an epub and a single page manual. mmdoc is building a multipage, singlepage, man, epub, and search index, but yeah, maybe pretty close overall speed wise.05:18:04
@infinisil:matrix.orginfinisilYeah and closure sizes are also comparable (70MB vs 200MB)05:22:36
@ryantm:matrix.orgryantm

Oh wait, I don't think that time is apples to apples:

this derivation will be built:

05:22:56
@ryantm:matrix.orgryantmThe manual is already built as the inputDerivation to that derivation.05:23:37
@ryantm:matrix.orgryantmNix is so hard to benchmark with the all the caching and indirection.05:24:40
@infinisil:matrix.orginfinisil ryantm: Not sure what you mean, I'm pretty sure nix-build --check pkgs/top-level/release.nix -A manual is the actual build, it's not just a dependency 05:25:23
@infinisil:matrix.orginfinisilAnd the command you pasted failed05:25:33
@ryantm:matrix.orgryantmAh yeah, oops. Okay.05:25:53
@infinisil:matrix.orginfinisil (gotta build without --check first.. yeah not a great interface) 05:25:58
@ryantm:matrix.orgryantmRedacted or Malformed Event05:26:59
@ryantm:matrix.orgryantmUpdated the gist again. Looks like the nixpkgs closure is bigger, but the nixpkgs closure matters less.05:28:28
@infinisil:matrix.orginfinisilCould you post the results in the github issue? I'm overall not very convinced that this is worth it though ๐Ÿ˜…05:29:31
@infinisil:matrix.orginfinisil * Could you post the results in the github issue (ideally a nice markdown table with the numbers)? I'm overall not very convinced that this is worth it though ๐Ÿ˜…05:29:46
@ryantm:matrix.orgryantmYeah there's a lot of hate for C.05:30:00
@ryantm:matrix.orgryantmand your thing is already working mostly, though not multipage.05:30:23
@ryantm:matrix.orgryantmSeems reasonable not to switch.05:30:26
@infinisil:matrix.orginfinisilI feel kind of bad, you worked on this for so long ๐Ÿ˜…05:31:07
@ryantm:matrix.orgryantmI'll take down my multipage manual when we publish official ones.05:31:08
@ryantm:matrix.orgryantmNo big deal, I still love the project independent of Nix accepting it.05:31:34
@ryantm:matrix.orgryantmI use it for all my projects and blogs and stuff.05:31:44
@ryantm:matrix.orgryantmI love the easy interface with no config I came up with.05:31:59

and your thing is already working mostly, though not multipage.
I've been told the code is literally there for it, though. so we seem to need to do some wiring.ย

@pennae:matrix.eno.space@pennae:matrix.eno.space(infinisil requested our presence :D)09:24:07
@fricklerhandwerk:matrix.orgfricklerhandwerk
In reply to @rina/:matrix.org
i am starting to see that. though, i do not mind pitching in where i can :)

What would you be interested in taking a closer look at? It would also help knowing what you may have had experience with already, to find something that wonโ€™t overwhelm or frustrate you too quickly. Feel free to DM me if you donโ€™t want this public.

Not everything needed to get started is written down nicely yet, so I can offer a brief guided tour of the various construction sites.
