How to read the source code of eta for learning purposes´╝č
Javier Neira
@jneira
the source is in GitHub https://github.com/typelead/eta
limengyu
@limengyu1990
I found the source code, but I want to know where to start reading. because the source code is too large. .
In addition, is there an example of eta and springboot integration..
Javier Neira
@jneira
@limengyu1990 the unique workaround is build it from source

Hey y'all. I have a Java project, and I'm interested in transitioning to something more functional (I have experience with Haskell). I was initially looking at Scala before I found Eta and Frege but they both look kind of unmaintained. Is Eta unmaintained, or just passively maintained with no big contributors? Thanks!

Hello! I have a small Haskell lib https://github.com/input-output-hk/cardano-addresses , I'd like to cross compile it to a JVM compatible jar. Am I in the right place? Does this even make sense? Thanks!
Alberto
@agocorona
I think so!

The installation steps does not work from binaries (the hostname cdnverify.eta-lang.org does not exists) and from source the stable branch (with the error of hpc is required and then with a compile error building the happy package)
What a shame, I'd really liked to use Eta
Carlos Saltos
@csaltos
I'm able to use the Docker version, cool !! ... I hope we can make this project have momentum ... Haskell at the JVM is a new dream now ;) :)
Javier Neira
@jneira
yeah, I hope it can be reactivated at some point ­čÖé

Does anyone here have a (partial) copy of the cdn, that i could use to set up my own cdn? (Or an idea of how to rebuild the cdn)
Javier Neira
@jneira
no copy here, I guess you will have to dive in etlas/gradle plugin to setup a thing which make it happy (and change URLs, not sure if they are configurable)

anyone able to build eta from sources using stable branch ?
build failed twice for different packages

HttpExceptionRequest Request {

I am trying to understand what and why sending request to register ?
Can we not build Eta offline ?
Javier Neira
@jneira
mmm it should be possible I think
@phoenix2082 what version of stack are you using?
I would upgrade if it is not the lastest
phoenix2082
@phoenix2082
I am just running ./install.sh
stack version > Version 2.3.3
phoenix2082
@phoenix2082
eta install script also uses Gradle 5.0.0 version
as I was using Adopt Open JDK 14 that was all causing build failure
right now I have changed JAVA_HOME to Adopt OpenJDK 14
Javier Neira
@jneira
aha, stack needs downloads libs from internet so at least the first install needs a connection
phoenix2082
@phoenix2082
yes. but it seems it sending request to that endpoint.
method = "POST" host=casa.fpcomplete.com
do all dips get downloaded from that end point
and it is downloading isn't it should be GET request?
phoenix2082
@phoenix2082
*deps
Javier Neira
@jneira
not sure if it follows rest, the path is pull so it tries to get that dep
but it is a stack thing in any case
you don't have internet connection available?
phoenix2082
@phoenix2082
I had. Not sure if it was slow intermittently and causing timeouts. I was able to build from source though and able to run hello world program.
Is there a way to run REPL like ghci ?

@joecrayne
Hello. I'm new to Eta. How do I get started? I don't see a download link. I'm on debian linux.
I want to use Eta to port a my haskell code to android. Is that reasonable?
joecrayne
@joecrayne
I'm having a really hard time building eta
stack doesnt work
and cabal with ghc-7.10.3 is failing with linker errors
Roman / Nea
@romangraef
Desperation
weve all been there
phoenix2082
@phoenix2082
@joecrayne - What is version of cabal and stack on your system?
I am able to build eta from source few days back.
My stack version > Version 2.3.3 &
cabal version > cabal-install version 3.2.0.0
Javier Neira
@jneira
@joecrayne what was the error you got with stack? iirc you can build eta with newer versions of ghc, I think 8.6
8
8.6.5 should work
