Not sure what should I do now, can anyone help me on this?

I'll restart it asap no worry about that

thanks!

did 0.10 regress it?

OMG

Benchmarks can change but if continue failing I will take a deeper look

Hi, found a pretty significant issue with helios today. The string encoding implementation currently does not escape any characters, so the encoding of a JSON that contains a multiline string would result in an invalid JSON. @AdrianRaFo Do you accept PR’s for this issue?

Sure, go for it

Also have a pending PR, could we maybe discuss this one?

Oh right, that’s on me. I just got back from vacation this week, I’ll check it out tonight!

Thanks a lot 👍

Hey @ambrusadrianz, I checked out the PR and left 2 comments. Looking great! If you have any questions I’d love to help you out 🙂

Hey! Sure, I will address the comments, if there’s a question I’ll let you know.

Hi @AdrianRaFo, can you help me out with something regarding my PR? How could I write a semigroup with extension function to JsNull?

since it’s an object

Also I’m not sure if we should implement Semigroup’s for all these classes, since they could be combined multiple ways (add, subtract, divide etc. for numbers).

We also shouldn’t implement a generic JsonSemigroup because how would you combine a JsDecimal(“1.33”) with a JsString(“abc”)?

We typically expose a default instance which is

add

for numbers and

concatenate

for Strings

The idea is that user can always provide their own strategies since it’s all just a parameter in the function. With typeclasses support and the compiler can automatically provide them you can still do a local override or manually pass another instance.

Hei. When can we expect to have another release in helios, as the currently released version is pointing to 0.9.0.

@simon.vergauwen!

Another question, arrow has another module in incubation

arrow-integrations-jackson-module

, is that ingration for Helios like Retrofit example on the website ? In most webapp frameworks like ktor, spring, usually there are 2 places where one registers encoders and decoders. 1. While intercepting an incoming request, to convert the json payload into data classes, and outgoing response to covert data classes to json strings 2. http clients, where basically same thing happens. Would Helios in the future provide any support for these scenarios with types and apis, like retrofit? Also I see that Helios uses Either for parsing return type, are there plans to use IO/BIO in future?

Hi Satyam, We currently don’t have a lot of focus on Helios, it’s completed logic wise but we’re not happy with the current

Encoder/Decoder

solution since we cannot generate them at compile time at the moment. Later this year with Kotlin 1.4 that would change, and we could automatically provide all of them and guarantee it at compile time.

Not sure what the jackson modules contains, would need to check

To answer your 1/2 question, this could be the same as what people do today for KotlinX serialization or seemingless where no user-code is needed but a compile error would be provided if the configuration could not be satisfied.

Also I see that Helios uses Either for parsing return type, are there plans to use IO/BIO in future?

Either

is a more generic type, and the code in

Helios

is pure, or in other words it does not throw. You could easily lift it into

IO

or

BIO

if you want to run the parsers as an effect on a certain context.

IO { Json.parse… }

Awesome. Thank you so much. Then it makes sense to wait a little. I can surely use it anyway in my own projects. But would be nice to introduce it when it’s more seamless.

@raulraja Pointed me here to get some help

Is this project half dead? It is broken using Kotlin 1.4.x: https://github.com/47degrees/helios/issues/141
