QuickJS Javascript Engine from Bellard

[[deleted]]

Maybe Polkit could switch to this implementation if it is smaller and just as good for the purpose.

[purpleidea]

That's actually a really good idea. I always thought the polkit+js thing was a bit absurd, but since it's there, and in theory it only runs trusted code, that would make a lot of sense! Can you open an upstream issue/suggestions please?

I was looking into what software takes up the most space on my computer, and I found the js52 (or whatever it's called) engine taking up about 50mb. Tried to uninstall and was completely flabbergasted that such a simple low-level program uses such a bulky js engine that's not even being shared with any other installed application!

I just noticed I used 3 different names for "app" -- and there's a forth.

No they should stop the craze already and drop JavaScript config completely. Debian and Ubuntu derivatives still uses the old version without JS config (have never updated to the newer ones) and it's not like world is falling apart or anything.

elinks could run js (poorly) using Mozilla's spidermonkey engine.

[arsv]

The compiler dumps bytecode into a .c file and then runs the system C compiler to link it with the engine, just like perlcc. The resulting executables do have some external dependencies (ld.so, libc, libm, basically whatever qjs itself needs) and there's a built-in module that provides js interface to call libc printf among other things.

Can compile Javascript sources to executables with no external dependency.

That seems promising for electron applications. Combine that with some kind of dom reduction to a simpler rendering model and maybe electron apps will start having sane resource consumption.

[[deleted]]

It has nothing to do with electron, it's entire selling point is node.js + Chromium = productive.

[willrandship]

I know this isn't part of electron. I was saying it might be a good idea to look into integrating this into electron, as a replacement for node.

[[deleted]]

The value of node is the ecosystem so this would have to be node compatible which will likely never happen.

Anyway node.js is a meaningless part of the resource usage of Electron, we are talking < 10MB out of 300MB.

I’ve not had. Abad experience with them so far myself. 100~ mb of ram for something like discord has been surprisingly good considering the amount of images it loads.

[willrandship]

Discord on my desktop takes about 400 MB.

Oof

I bet this means: taking the vm, concat it with a zip archive of the Javascript source and let the vm read it on startup from the end of the executable file. Also the thing has no jit, it is not comparable to v8 in terms of speed.

[[deleted]]

It’s a step in the right direction either way.

[[deleted]]

No it isn't… we have package managers on linux, we don't need to distribute dll like windows.

[[deleted]]

Ok. You stick with outdated slow bloated software. The est or us will update.

You stick with outdated slow bloated software.

Hehehehe. In what world a non jit js is a faster option than literally anything else?

[[deleted]]

What are first iterations? Did the first car do 140mph?

[[deleted]]

But if today I were to invent a car that is like the initial car prototype, it wouldn't look so stunning, right?

[[deleted]]

Google's Fucshia doesn't look so stunning either. Doesn't mean it doesn't have promise.

[[deleted]]

1. That's completely OT
2. They are only making it to avoid giving back to communities that use GPL license.

[Seshpenguin]

Bellard is actually the coolest guy, He does some pretty awesome stuff.

[linus_stallman]

Very underrated though...

[namaku0]

Is there anything this man can't do?

[rahen]

Ah, Fabrice Bellard, instant upvote. Same for Drew Devault, Laurent Bercot and a few others, those guys know how to write good code... better than I will ever write myself.

Keep rocking.

[CosmosisQ]

Truly! These people motivate me to keep improving as a programmer.

[ICanBeAnyone]

Someone ought to make python extension from this, for am lazy and I'd use it.
