A modular functional UI language for Android

Niklas Klein

@Taig

@clinoge try to suppress the warnings in your ProGaurd config to get the app running. If that doesn't cause runtime errors you're fine

Raúl Raja Martínez

@raulraja

@javipacheco are we seeing those in nine cards too? If so what is the way to fix them?

Javi Pacheco

@javipacheco

We don't have this problem @clinoge Anyway, the TR (TypedResource) is a class for scala-android plugin. Maybe you can upgrade the plugin or ask in the GitHub of sbt-android project. Sorry, I can't help you about it

Carlos Gottberg

@clinoge

No problem at all ^^. Today I hit another problem, but it might very well be my fault. When trying to tweak a Button

w[Button] <~ lp[LinearLayout](64 dp, WRAP_CONTENT, 1)

I'm getting java.lang.NoClassDefFoundError: Failed resolution of: Lscala/math/Numeric$IntIsIntegral$; at runtime :/.

The only extra options I'm giving ProGuard are

proguardOptions ++= Seq(
  "-dontwarn com.fortysevendeg.macroid.extras.*",
  "-dontwarn scala.async.internal.*",
  "-dontwarn scala.xml.parsing.*"
)

sbt android:run doesn't show any error at all. I don't think it's related to ProGuard... or maybe it is? I get the error from logcat :).

Hi folks,

GRBurst

@GRBurst

Is there a way to use Futures with listables, e.g. to tweak my ListView with Future[List[something]]?

val l: Future[List[Int]] = Future { List(2,3,4)}
userListable.listAdapterTweak(l)

GRBurst

@GRBurst

sry was not clear to me but this does the job

l.map(li => userListable.listAdapterTweak(li))

Raúl Raja Martínez

@raulraja

@GRBurst if you are not keeping the results of those tweaks you may want to use foreach instead of map to be explicit that you are performing side effects and it’s an impure operation.

GRBurst

@GRBurst

@raulraja yes you are right, thanks for the hint :-)

@yilinwei

@raulraja are there any plans to make macroid compatible with iOS?

Raúl Raja Martínez

@raulraja

@yilinwei I don’t know enough swift to determine if the lang would support a similar DSL. There is some Scala specific semantics that would need to be workaround or not provide parity of features. Do you have a use case?

Yilin Wei

@yilinwei

@raulraja I don't quite currently (I have a similar compat issues so I was looking to see what you guys were doing) - but why do you want to use swift? There are several VM's which allow you to compile java code to obj-c

We had a few PoC with RoboVM originally but that sadly died.

And from working with swift you won't be able to do anything close to as rich - though it may have changed in the 1 year that I haven't used it.

Raúl Raja Martínez

@raulraja

@yilinwei I thought you implied swift as nobody today uses Scala on iOS AFAIK. Hopefully Scala native would open some doors there, but still to early.

Yilin Wei

@yilinwei

Like I said there are a few JVM's which run on iOS (Unity iirc uses a .NET based one, libGDX uses Xamarin atm). I don't expect the performance of scala on iOS to be particularly much worse than android.

Raúl Raja Martínez

@raulraja

@yilinwei Are there any bindings to access UI stuff from Scala in iOS land in any of those platforms?

Yilin Wei

@yilinwei

@raulraja Originally RoboVM has access to the API stuff (touch gesture etc...); Intel's JVM (which is what the libgdx) should also have bindings. We're probably going to do a deep dive on the JVM stuff in ~ 3 - 6m so we could sync up at that point to see whether it's feasible (since we'll have to perf test etc...).

Raúl Raja Martínez

@raulraja

sounds good, looking forward to learn more about it.

I wish there was a comparison chart of macroid with anko.

The Almikey

@TheAlmikey_twitter

hey came across some dead link on the macroid page, like this one http://47deg.github.io/macroid/docs/api/core/macroid/Tweaks$.html , the pages have been moved to a new url maybe?

Raúl Raja Martínez

@raulraja

@javipacheco do you know if the scaladocs are getting published somewhere ^^^?

Raúl Raja Martínez

@raulraja

@TheAlmikey_twitter scaladocs are no longer getting published. I created 47deg/macroid#106 which will be adressed in the next sprint to fix those links and point to the actual Github sources.

The Almikey

@TheAlmikey_twitter

Cool, thanks. Really want to explore the lib cant wait :thumbsup:

Hi, are there any examples using ConstraintLayout? All the layouts I've tried worked fine, except for this one.

scalac keeps saying "Could not find the appropriate LayoutParams constructor" when I use lp[ConstraintLayout] ()

Raúl Raja Martínez

@raulraja

@yoo-haemin feel free to file an issue and we will look into adding support for that if it's broken. /cc @javipacheco

Rytis Jazdauskas

@RytisJ

how does one add error handling on a listview?

this doesn't seem to work :s

w[ListView]
          <~
          new BackendConnector()
            .getJars
            .map(UserListable.listAdapterTweak)
            .recover {
              case _: JsonParseError | _: BackendException =>
                toast("Service unavailable, try again later") <~ long <~ fry
                UserListable.listAdapterTweak(Nil)
              case _: NoInternet =>
                toast("Turn internet on and try again") <~ long <~ fry
                UserListable.listAdapterTweak(Nil)
            }
          <~ CustomTweaks.List.noHighlighting + ListTweaks.noDivider

Javi Pacheco

@javipacheco

@yoo-haemin maybe you have to use l[ConstraintLayout](), not LP

Zachary Albia

@zalbia

hi, is there a way to center widgets horizontally in macroid?

There didn't seem to be any yet, judging by the source code. Maybe I missed something?

Raúl Raja Martínez

@raulraja

@zach-albia You can use a tweak to access the view and apply any transformations you wish to the view, including changing its gravity and position parameters http://47deg.github.io/macroid/docs/guide/Tweaks.html

Zachary Albia

@zalbia

@raulraja Ok, I'm getting the sense that lp[<LayoutHere>] is what you meant. As I understand it now, I think this is how you add any arbitrary layout tweaks to a view. Thanks!

Raúl Raja Martínez

@raulraja

Yeah you can apply tweaks to views in layouts. Tweaks are ui actions. There are several examples here of views getting tweaked and applied here http://47deg.github.io/macroid/docs/guide/Tweaks.html

Zachary Albia

@zalbia

hi, would there be value in adding a

def margin(left: Int = 0, top: Int = 0, right: Int = 0, bottom: Int = 0, all: Int = -1): Tweak[View]

tweak, in the same fashion as the paddingtweak?

because I noticed that in previous versions where macroid.extras was still outside of macroid, there were tweaks like vMargin which do the same thing, but don't exist anymore in the main macroid repo.

Raúl Raja Martínez

@raulraja

@zach-albia yes, that will be valuable, feel free to submit a PR

Zsolt Szilagyi

@esgott

hi All, I'm pretty new to macroid. Is it possible to build AppWidgets with it? Didn't find anything about it in the docs

Raúl Raja Martínez

@raulraja

@esgott AFAIK since those are just views you can potentially use macroid's dsl there as in a regular activity or fragment but to my knowledge nobody has attempted that yet.

Felix Dietze

@fdietze

Hi, I'm trying to create a https://developer.android.com/reference/android/support/constraint/ConstraintSet.html#connect(int,%20int,%20int,%20int) tweak for ConstraintLayout. The problem I have is, that for applying the tweak, I need access to the view AND to the layout by calling https://developer.android.com/reference/android/support/constraint/ConstraintSet.html#applyTo(android.support.constraint.ConstraintLayout). So how do I do it?

@frgomes

Hello. I'm new to macroid.
I've created a PoC which is just the macroid-starter example with a few updates:

SBT 0.13.16
Scala 2.11.12
sbt-android 1.7.10

I'm using macroid 2.0.0-M5.

It works fine in the emulator, which is good. But IntelliJ complains that it cannot find several classes. This is a bit inconvenient because I cannot easily study the sources in deep detail.
Is that only me or IntelliJ is not really able to find the classes for some reason?
Thanks

Richard Gomes

@frgomes

Hello, any idea why SBT cannot find macroid 2.1.0 ?
