Create a File With Amber

Hello,

I work on a university project in Amber, I must move an application in
Smalltalk to Amber. I need to create 3 files .xml .csv .dat but I
don't know to do that.

A way is to use Ajax for sending text to the serveur and using PHP but
I want to do that with only Amber, any idea?

In an other message, I discover the library raphael.js and I think
that i can use this to create an Image with LineSegment,... But
anybody say how to use this? I don't know use a Javascript Library.

Sorry, my english isn't perfect,

Thanks,

Muriel

Hi!

Your english is fine, no problem. If you both want to build a web front end AND need to create files on the server the simplest approach is to just use the same setup that the IDE uses when you use the little webDAV server that Nicolas wrote that is under bin:

1. You build an Amber UI and then use code like you will find if you search for "commit" (I think the method is called that). I can post a followup when I get off the subway.

2. You just use the server Nicolas wrote, if you just want to save files to the server you will not even need to modify it.

Regarding Raphael, yes, quite nice - I have been working with graphs lately too and we use Highcharts, a very nice js lib. I should make some example with it.

regards, Göran

Re: Create a File With Amber

Oh thanks, I had not thought!

Yes, I find the method ajaxPutAt: in the version 0.9.1. I begin to
work with the previous version of amber, I don't know if the method is
the same but in the new version I can't find class AjAx and JQuery so
Can i do Ajax new url:' ' onSuccessDo:' '? I am not on my laptop
today I can't verify it.

I don't know to use Javascript libraries in Amber, I just load it in
index.html and call it like that: <....>? If you can give me some
examples, it could be very interesting because I need to build a
complete application.

Ps: I don't use node.js, I use a PHP server because I need to upload
files on server and I find anything about uploading on Amber. My php
server isn't configure for PUT request, I don't know how to do it. It
seems that it could be a problem for me...

In Amber 0.9.1 the jQuery binding is gone, simply because we don't need
it anymore. There's no Ajax class anymore. Therefore you can do:

jQuery
ajax: anURL options: #{
'success' -> ["do something here"].
'error' -> [window alert: 'something went wrong'!]
}

which is equivalent to:

jQuery.ajax(anUrl, {
success: function() {},
error: function() {window.alert('something went wring!')}
});

See http://api.jquery.com/jQuery.ajax/ about jQuery and this:
http://amber-lang.net/documentation.html#JSObjectProxy about sending
messages to JavaScript objects.

Hope this helps,
Nico

Re: Create a File With Amber

Love it. Makes it painfully easy to include *whatlibever* into Smalltalk syntax!

A great step forward for the Smalltalk community!

Tnx, Guido Stepken

...and yes, you can also use < ... > but if you can avoid it and just
use Amber Smalltalk code - it looks and integrates much nicer :)

Re: Create a File With Amber

Hi,

Now I can create my files, it's so good! But now I have some problem
but it's not important like method removeFirst that isn't implement.
Thanks.

I discover the library highChart, it's good for me. In javascript I
want to write code like:

var options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'line'
},
title: {
text: 'Trait de cote'
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'Distance'
}
},
series: []
};

$.get('test.csv', function(data) {
// Split the lines
var lines = data.split('\n');

// Iterate over the lines and add categories or series
$.each(lines, function(lineNo, line) {
var items = line.split(';');

if (lineNo == 0) {

$.each(items, function(itemNo, item) {
if (itemNo > 0) options.xAxis.categories.push(item);
});

}

// the rest of the lines contain data with their name in the
first position
else {
var series = {
data: []
};

$.each(items, function(itemNo, item) {
if (itemNo == 0) {
series.name = item;
} else {
series.data.push(parseFloat(item));
}
});

options.series.push(series);

}

});

// Create the chart
var chart = new Highcharts.Chart(options);
});

</script>

</head>
<body>
<div id="container"></div>
</body>

</html>

With files that I have created. But I don't now how to use it in
Amber.

Humm, I don't see Jquery method in the Browser on Amber (like ajax:
for ewample, it's hide??)

Thanks,

Muriel

Re: Create a File With Amber

Hi!

Yes, Highcharts is very nice, we use it at work a lot. Regarding not finding jQuery methods etc, that is because Amber can use js libraries without any wrapper classes or other glue code - check the new documentation, read about JSObjectProxy in Kernel-Objects.

Re: Create a File With Amber

IMHO the best ideas in software engineering the last decade. Got this game painlessly converted to Amber Smalltalk within a few hours: Try the JS version here:

http://sebleedelisle.com/demos/JSTouchController/TouchControl.html

Sources:

http://github.com /sebleedelisle /JSTouchController

Authors homepage and videos:

Tnx so much! Keep up the good work!

Re: Create a File With Amber

Hi, I have an other problem!

I have created 5 classes and one of these have 3 subclasses but this
class don't appear when I reload the page.
But I have committed the package and I can see classes in JS files, I
don't understand how to see my classes.

Thanks,

Muriel

Do you have an error in the JavaScript console when your JS files are
loading?

Re: Create a File With Amber

Concerning the us of js librairies, can I create a variable like that
<
options = {
chart: {
renderTo: 'container',
defaultSeriesType: 'line'
},
title: {
text: 'Trait de cote'
},
xAxis: {
categories: []
},
yAxis: {
title: {
text: 'Distance'
}
},
series: []
};>

or <var myArrayName=[];>

Or no?

I try to do this:

html script
type: 'text/javascript';
src: './js/highcharts.js'.
html script with: <script javascript>
html div id: 'container'.

But it doesn't work, I don't be surprise.

I must to write like in smalltalk like: Highcharts.Chart new options:
options. for example?
Sorry, maybe it doesn't difficult but I am new in amber and I never
see a concrete example with another librairies that jquery.

Thanks,

Muriel

Re: Create a File With Amber

Finaly, I insert the script (aString) in the tag Script of my html
canvas and it's work. So I can't use the library like Smalltalk but my
aim it's just to create a chart to verify data that I have created.

regards,

Muriel
