@freemo
@jneira hmm might be doable then.. its a hard decision for me to make. I want to use haskell for the fun of it, I dont have a good reason beyond that. So the risks are a bit tougher to swallow
I'm tempted to just bite the bullet and give it a go
Javier Neira
@jneira
Sounds good, dont hesitate in posting any question here or in the github issue tracker
Jeffrey Phillips Freeman
@freemo
I will thank you
Jeffrey Phillips Freeman
@freemo
Does ETA fully support all java features... in particular can I write generic interfaces on the ETA side to be seen by the java side?
Javier Neira
@jneira
No specifically interfaces: you can export static methods or instance methods, with generics type parameters public <A> A static myMethod(A my param)
see https://eta-lang.org/docs/user-guides/eta-user-guide/java-interop/java-interop-basics#exporting-eta-methods
Jeffrey Phillips Freeman
@freemo
darn, if i cant produce interfaces I wont be able to use ETA for my project, since the purpose is to write a library intended for Java consumption and you cant do that (Sanely) without interfaces and generics :( Hopefully ill get a chance to try ETA another time.
Thans for your help though
Javier Neira
@jneira
mmm you can include java files in the eta project with the interfaces and use it for the default implementation(s) with haskell code, using exisiting packages
i did something alike to make a port between the dhall prog lang, written in haskell and java client code
Jeffrey Phillips Freeman
@freemo
Can I have *.java directly in an eta project? I thought java files would have to be in a seperate jar?
Javier Neira
@jneira
yeah, you can: see https://github.com/eta-lang/dhall-eta
Jeffrey Phillips Freeman
@freemo
ahhh ok yea that might be doable then, thanks ill check it out
Javier Neira
@jneira
that was my more elaborated lib using eta with the goal of being used from java client code
you can add the java files in the .cabal config file: https://github.com/eta-lang/dhall-eta/blob/master/dhall-eta.cabal#L88
But you can use gradle too: https://github.com/eta-lang/dhall-eta/blob/master/build.gradle

@freemo
awesome! thanks

Is eta still alive?
Javier Neira
@jneira
Well, it is not dead 😜
Sam Grönblom
@sgronblo
https://github.com/typelead/eta "Latest commit Jul 16, 2019" Failing its tests even.
Javier Neira
@jneira
No bugs introduced since that date! 😛
Seriously, the released version is relatively stable, but the development is not active right now
So probably anybody using them will have to work on the tool itself
Sam Grönblom
@sgronblo
So what happened
Javier Neira
@jneira
Citing @rahulmutt (project owner):
"Hey guys, just wanted to announce that I’ve joined Symbiont as a full-time engineer. Things will move as usual, just a lot more slowly since I’ll be working at my leisure. For anyone looking to contribute, feel free to reach out as we could really use the help to speed things up a bit."
Sam Grönblom
@sgronblo
Thanks. That to me sounds like the end of Eta though.
Javier Neira
@jneira
Well, take a look at ghcjs, it is not very active (i have a pr to add support for windows for one year)
But i think having a haskell compiler to jvm bytecode has still sense, so i hope some day it can be reactivated in some way
Sam Grönblom
@sgronblo
Yeah I always was interested in this project. Even though I work in TypeScript and Node mostly. But I understand that Rahul has to support himself.

Is there any possibility to support installation using Gradle >4.8
It seems that currently there are issues with installation on those versions. I'm trying to integrate with a large project that uses Gradle 6.2
Javier Neira
@jneira
It is possible for sure, but there are not active contributors with Gradle knowledge right now
santiweight
@santiweight
Oof - hmmm. I'll take a look this weekend - I'd really like to suggest eta for the company I work at - we're building compilers to run on the JVM. I guess Frege is the other option :( But I want my sweet sweet GADTS.

I created a ProjectName.cabal file to import local java jars, but when I run:
./gradlew repl --no-daemon -q --console plain
I get this error:
etlas: can't find source for ProjectName in src
Here is my .cabal file:

name: ProjectName
version: 0.1.0.0
build-type: Simple
cabal-version: >= 1.10

library
hs-source-dirs: src
exposed-modules: ProjectName
build-depends: base >=4.8 && <4.9
default-language: Haskell2010
java-sources: /path/to/jar/LocalJar.jar

anyone know/remember where you can find detailed info on failed builds? I run into this: 
Building mono-traversable-1.0.15.1 (lib)...
Building library for mono-traversable-1.0.15.1..
etlas: Failed to build mono-traversable-1.0.15.1 (which is required by
yaml-0.11.4.0). See the build log above for details.
but I do not find a build log with details
@rahulmutt, we need you back!
Joshua Shinavier
@joshsh
actually, I think I found the source of the problem (no support for DerivingStrategies), but I do hope Eta will continue to be supported in the future. The acceptance and success of Haskell at my company might depend on it, as we need easy integration with at least one of our officially supported languages (Go and Java)

Hi. Does eta REPL compile/jit-compile expressions to native code or does it interpret them?

@jirkavrba
Hi I just wanted to point out, that you have an expired certificate on the eta-lang.org domain
ShalokShalom
@ShalokShalom
@jneira How is the support for error messages? I know they are like in Elm here, but how far have they been integrated?
Javier Neira
@jneira
afair it was done for some errors by Jyothsnasrinivas, changing directly the compiler, but I don't find the relevant commits/pr now
ShalokShalom
@ShalokShalom
Well, there is a tweet on her Twitter account, pinned to the top
But I would more like to know, if I can use Eta as a replacement for GHC in regards to compiler messages?

@alvarofgd
I'm trying to install eta lang... I went the gradle way, and then tried to download etlas and the URL lands me in a Disney site with no binaries... does anyone know what's happening?
