 alexfmpe | I'm not sure if -dedupe per-se will come back | 23:05:36 |
| alexfmpe | doyougnu: do you...gnow? | 23:05:49 |
|  Kyle joined the room. | 23:30:40 |

| @dmjio:matrix.org | alexfmpe: w/o the -dedupe too .. not sure if that even does anything anymore. There was a time when js-sources were duplicated in all.js though. 3x smaller | 23:54:07 |
| @dmjio:matrix.org | $ nix-build --arg examples true -A miso-examples
| 23:54:54 |
| alexfmpe | Hmmm about 2.5x or so. I wonder if the gap goes down considerably post closure and compression | 23:56:09 |
| alexfmpe | Though... it might already be less bloated than 10 | 23:57:06 |
| alexfmpe | * Though... it might already be less bloated than 8.10 | 23:57:13 |
| alexfmpe | Huh I wonder if I can already build my project with 9.12 js backend | 23:58:00 |
| alexfmpe | Ah one thing though | 23:58:56 |
| alexfmpe | The stuff coming out of the derivation I pasted and it's all ~10MBs | 23:59:23 |
| alexfmpe | I think that's an actual executable | 23:59:33 |
| alexfmpe | At least it is for the hello package | 23:59:53 |

| alexfmpe | I'm not sure what else is there, maybe just a call to nodejs | 00:00:43 |
| alexfmpe | * The stuff coming out of the derivation I pasted where it's all ~10MBs... | 00:01:08 |
 Tristan Ross | https://endoflife.date/ghc this is fun to look at, anything older than 9.2 isn't supported at all. | 00:04:22 |
| @dmjio:matrix.org | ❯ nix-shell -p closurecompiler --run 'closure-compiler -W QUIET < ./result/bin/simple.jsexe/all.js > out.js && du -hs ./result/bin/simple.jsexe/all.js out.js'
The compiler is waiting for input via stdin.
4.5M ./result/bin/simple.jsexe/all.js
3.7M out.js
| 00:07:26 |
| @dmjio:matrix.org | seems advanced opts aren't working with this version of closure compiler, even when externs are specified | 00:07:55 |
| alexfmpe | by "aren't working" do you mean incorrect behavior or just less savings that it used to? | 00:13:49 |
| alexfmpe | because I see use of ADVANCED in hello world example in https://gitlab.haskell.org/ghc/ghc/-/issues/24584 | 00:14:37 |
| alexfmpe | haven't yet tried out closure on actual js backend stuff | 00:14:56 |
| alexfmpe | though I think we're in the wrong room to continue this conversation | 00:15:17 |
| @dmjio:matrix.org | -O ADVANCED > out.js gives me a 0B file. The version of closure compiler miso uses is old. This one I just pulled from nixpkgs 25 | 00:15:27 |
| alexfmpe | shall we move this branch to #ghc-js-backend:matrix.org ? | 00:15:41 |
| @dmjio:matrix.org | sure | 00:16:09 |
 Divam | I agree with maralorn; for all projects I am aware that still use ghcjs from nixpkgs (via the old reflex-platform), there won't be a migration to newer nixpkgs. | 04:38:20 |
 eldritchcookie | i've spent the better part of today to get fourmolu to compile on ghc 9.12 but one of the fixes need fourmolu version 0.18.0.0 but the latest one available from nixpkgs is 0.16.2.0 what is the solution? | 23:04:48 |
| eldritchcookie | because i intend to upstream my fixes | 23:05:52 |
 maralorn | Is that on the haskell-updates branch? Seems unlikely that that wouldn't have a newer version. | 23:09:29 |
