if Ruby and React had an indentation based lovechild, what would it look like? Imba is a new programming language for the web that compiles to performant and readable JavaScript.

@altteo

also i vote for exlicit properies declaration

in this case we can use @ for public properties and # for private. I mean it is convinient when properties are colored, it is pretty obvious what are you changing just from highlight.

Fedor Leschinsky

@altteo

@somebee Huston, we have a problem. It seems that I’m the first developer on Windows who tried Imba 2. Because of the difference in paths nothing works (compiler and rollup).

Sindre Aarsaether

@somebee

:P someone has to be the first

We'll take a look. Maybe @scanf can get it running :smile:

Fedor Leschinsky

@altteo

I could do it. The only thing I could not figure out where and when you remove all "\" from OPTS.imbaPath

Oh, it is removed later. The thing is that you should use path.join for cross platforms.

Sindre Aarsaether

@somebee

Yeah, we definitely need to fix this

Are svg's working in imba2? I'm not sure if it's been discussed.

@scanf

Yes, SVG seems to work. I can make you a nice example.

BTW, if anyone else is struggling with inconsistent indentation on Scrimba. Sindre added the cool SHIFT+ALT+I to make it obvious.

Alexander Alemayhu

@scanf

What do people think about moving to a self-hosted version of Mattermost?

We could run it on chat.imba.io, https://mattermost.com/

Sindre Aarsaether

@somebee

I think discord is the best alternative to gitter actually. Slack done right :j

Alexander Alemayhu

@scanf

Maybe discord is better.

Has anyone else experienced this? I am trying to port an old OpenGL example

@somebee

Oh, this is a compiler infernals error. Startes to improve these error messages yesterday

I might be able to take a look around lunch

Alexander Alemayhu

@scanf

The weird thing is that it compiles fine locally with the latest Imba.

Alexander Alemayhu

@scanf

Actually it's just imbac that works, seeing the same error with the rollup hello world template.

Sindre Aarsaether

@somebee

May be because rollup uses older version of imba?

You could try updating to the latest v on scrimba

Alexander Alemayhu

@scanf

Hmm, I will look at it again later.

I will get a windows machine later today, so hopefully going to experience new issues there :D

Alexander Alemayhu

@scanf

What should the Imba v2 slogan be?

imba/imba.io#101

Fedor Leschinsky

@altteo

The web-language you will love :)

@scanf

:+1:

Eric Vida

@ericvida

@scanf I figured out svg's http://chico.tirado.app

Can I bind an input value to a parent's prop with
<input[#context.search]>?

Sindre Aarsaether

@somebee

Nope - I dont think so, but you can send it in using a special bind syntax.

Will whip up an example

Sindre Aarsaether

@somebee

@iamtirado you can bind props using this syntax: https://scrimba.com/c/c4Pa8ysL

Might change though

but this allows us to use the form bindings in wrapped components etc

Eric Vida

@ericvida

that's perfect.

Eric Vida

@ericvida

Can anyone help me convert this fuzzy search function to imba syntax? I'm getting too many errors. Maybe someone can help me do it well. I'm not sure how to get around the outer part.

'use strict';

function fuzzysearch (needle, haystack) {
  var tlen = haystack.length;
  var qlen = needle.length;
  if (qlen > tlen) {
    return false;
  }
  if (qlen === tlen) {
    return needle === haystack;
  }
  outer: for (var i = 0, j = 0; i < qlen; i++) {
    var nch = needle.charCodeAt(i);
    while (j < tlen) {
      if (haystack.charCodeAt(j++) === nch) {
        continue outer;
      }
    }
    return false;
  }
  return true;
}

module.exports = fuzzysearch;

```

Here's my attempt: https://scrimba.com/c/cD7QnBuv

Sindre Aarsaether

@somebee

We dont support labeled loops ATM - but it could be implemented with a slightly different approach. Will post when at my computer

Sindre Aarsaether

@somebee

@iamtirado See https://scrimba.com/c/cWKeRmt6

Not sure if it works - i found quite a few errors :) But you can at least check it out

Not sure if we will support labeled loops and continue/break (label name). Much more powerful to be able to continue and break with values (see bottom examples here https://www.imba.io/guides/language/loops#loops)

Eric Vida

@ericvida

Thanks for the example. I had never seen that the labels being used in Imba. I thought that might be it.

But i didn't know how to work around it.

Great examples in the docs too. i need to understand those better.

useful stuff

Eric Vida

@ericvida

What's the proper way to export and import a module? I can't get it to work.
Shouldn't I be able to do

---- fuzzySearch.imba
export fuzzySearch needle, haystack
        ...
---- app-root.imba
import fuzzySearch from './fuzzySearch.imba'
console.log fuzzySearch("one", "two")

using the imba2-hello-world example
