Haxe - The Cross-Platform Toolkit

Oh well yeah bills are real

But I think experienced compiler devs are scarce anyway. So maybe still worth a talk with the HF

Rudy Ges

@kLabz

I wouldn't mind following a proper compiler dev formation

Kevin Leung

@kevinresol

Let me bring this up (softly) in the haxe-dev 😜

@kLabz

:ok_hand: :laughing:

(it feels so weird waking up at 4am thinking of Haxe stuff, I deserve a better dream I guess... Cya...)

I’ll contribute to this crowdfund and if it happens, I’ll gladly fix the issues with the python target.

:) Haxe can hire me. Rather work on a compiler than figure out why 4Gl and PowerBuilder apps aren't playing ball.

Gabriel Hayes

@piboistudios

Does Haxe perform all the compiler optimizations on the generated code only or also to the IR?

Gabriel Hayes

@piboistudios

hxgenpe so far.

Right now, it is just a quick test that generates a "Hello, World!" executable assembly using Mono's Ilasm sources (converted into a class library), but this is what it looks like to hook directly into the Ilasm CodeGen API

Hey guys. Have you ever had a problem with haxe JsonParser throwing "Uncaught exception Invalid char 123 at position 337", but when you trace the input, then copy-paste it from the log file into a JSON validator, the JSON is actually valid? Somehow it happens on some of our CI servers but not the others, according to the log the input to Json.parse is exactly the same (same MD5). Running on haxe 4.1.5, eval target (within a build macro)

Peter Achberger

@Antriel

Maybe encoding playing a role?

Rudy Ges

@kLabz

It will be hard to help without the json part that fails on haxe =/

Gene Pavlovsky

@gene-pavlovsky

It turned out that the node process that generates the output sometimes was polluting stdout with some logging... Works after directing logs to stderr

I have a problem with a copied source directory in vscode the libs in the local .haxelib folder don't show up under Haxe Dependencies and the related libs imports within the code are underlined red as Type not found however the app compiles and runs as usual !? Any ideas how to tell vscode where to find .haxelib?

How are you running the build? Are you sure it’s building for js and not another target?

Rudy Ges

@kLabz

And if it's running for another target, how the hell does it end up with js-specific stringmap? :x

Nycole Xavier

@nycolexavier

How are you running the build? Are you sure it’s building for js and not another target?

how can I do this?

Thomas J. Webb

@thomasjwebb

Are you building on the command line or using a gui? If you run haxe manually, the -js argument builds for js. But if you’re doing something like “openfl build mac” then it will use the hxcpp target.

Gene Pavlovsky

@gene-pavlovsky

Looks like the single pattern check v.match(...) doesn't work for enum abstract types, is that right?

Thomas J. Webb

@thomasjwebb

That sounds right. Some things you can’t do because there’s no guarantee the value is one of your defined values.

Like when I do switch statements I have to always have a default iirc

Gene Pavlovsky

@gene-pavlovsky

Heh, it's a pity. We switched a lot of our Enums to enum abstract(Int) to reduce generated code size, but turns out some things are more comfortable with classic Enums

Kevin Leung

@kevinresol

It would be quite simple to add a macro to support that

serjek

@serjek

why macro

static function match<T>(a:T, b:T):Bool
    return a == b;

ah well for matching multiple values yes, a simple macro

serjek

@serjek

@gene-pavlovsky we can add this to our codebase. I know using context.parse is not classy but hey, it works.

Kevin Leung

@kevinresol

or you can just pass it to a switch case directly:
https://try.haxe.org/#9195cc75

public static macro function match(e:Expr, v:Expr) {
  return macro switch ($e) {
    case $v: true;
    case _: false;
  }
}

@PtrMan

I got a problem: I am trying to write a TCP server and get a exception Unix.Unix_error Unix.Unix_error(56, "recv", "") when ever a client disconnects

I am trying to catch the exception to handle the error but when catch(e: Unix.Unix_error) it doesn't compile because it can't find the namespace/class of the exception

so how to catch and handle it?

ah yes I am on windows

Emugel

@emugel

catch (e) will catch everything. To locate the namespace (or I should say package) I would just look for a file called Unix.hx in the computer and look at the first line beginning with package xxx.

Then you can use this name

PtrMan

@PtrMan

i can find the string online in the binary of haxe, because I am using --interp

I'll try catch (e) :)

I can't catch the exception :(

PtrMan

@PtrMan

in --interp

looks like a bug to me, because with --jvm traget I can catch something

Emugel

@emugel

Since you are dealing with a server, I suspect the uncaught exception has to do with the presence or absence of threads. Unfortunately I don't really know the interp target.

PtrMan

@PtrMan

yes I am using threads too, thanks for your help anyways

Emugel

@emugel

on cpp target if a thread is launched, a try/catch on the main process won't catch anything thrown from that thread. Anyway hopefully you will find or someone else helps :)

@senthilattivo

I want to add one of the native(android) activity on top of lime, is any one explore on this ?

pecheny

@pecheny

@senthilattivo Android project is based on template located in lime/templates/android. It can be overridden in your project (template tag in the project file iirc). For interop you can look at externs. Also you can find something useful in native extension like https://github.com/HaxeExtension
