[ANN] Launching Pharo on Ubuntu
For Ubuntu users who are using my PPA (https://launchpad.net/~pharo/+archive/stable/), you can now launch Pharo from either the Ubuntu Dashboard or the terminal (just type 'pharo'). In both cases, you will see the Pharo Launcher from which you can create new images from templates on the web and launch existing images. http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher No need for manual download of zip files, unpacking, and directory management. The launcher does everything for you. Have fun -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Very nice. Works on Mint, too. Could use more feedback, maybe: It's not always clear when it's doing something when you create an image. On Mon, Sep 23, 2013 at 5:56 AM, Erwan Douaille <douailleerwan@gmail.com>wrote:

yeah I will give it a try, don't know how long will take me but I like what you have done with Pharo Launcher. I will create an enhancement issue when I have it working as I want and report back. Esteban has granted me commit right to pharo 3 inbox too so I will commit there. Or do you want me to contribute directly to smalltalk hub repo ?

ah yes of course. Ok thanks for adding me. I took a look at the code, it points back to Zinc , it look like I would need to override ZnClient >> withProgressDo: , no Idea how to do this currently but will continue looking into . I also found how monticello uses progress bars when downloading repos but it does not seem to use Zinc at all. So yeah this will take me quite some time to implement.

Progress is indicated by HTTPProgress Notification that are being signalled by the underlying code. You have to catch them and do something with them. Have a look at ZnClientTests>>#testProgress Although the example in the comment does no longer seem to work...

Actually it works its just that is not meant to create a progress bar. To create a progressbar I created a new test testProgressBar UIManager default informUserDuring: [ :bar | [ ^ ZnClient new signalProgress: true; get: 'http://zn.stfx.eu/echo?delay=2' ] on: HTTPProgress do: [ :progress | bar label: progress printString. progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ] it displays the progressbar , but it displays no progress (blue bar thing) and it close as soon as it finish the get. I tried to implement that in createImageFromTemplate | name | name := UIManager default request: 'Image name?'. self showDownloadInProgress. [UIManager default informUserDuring: [ :bar | [ imageGroup extractTemplate: self selectedTemplate to: name] on: HTTPProgress do: [ :progress | bar label: progress printString. progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ]] on: PhLDownloadError do: [ :err | UIManager default alert: err longDescription. ^ self ]. self updateAll. I assume that code is deeply flawed , hence why it does not display me any progressbar at all. Looks like I have a lot to learn. First I am not sure if ZnClient downloads in packets and if it reports progress per packet . If its progress is upon success of download then it does not help at all , because in that case there will be only one stage of progress upon success of download. I want multiple stages of progress so the download bar increases from 0% to 100%(preferably per kb ). IF that is the cace then probably I will be better using the HTTP client of monticello to download the images which I know it works that way. Is there a particular reason why we should stick to Zinc ? I am open to suggestions :) Sven Van Caekenberghe-2 wrote

The HTTP client of Monticello _is_ ZnClient, see MCHttpRepository>>#httpClient ;-) Now, for performance reasons, progress in only signalled every ZnUtils class>>#streamingBufferSize which is currently 16K. Apart from that, the download might go that fast that there is little to show. I am certainly not claiming that the HTTPProgress stuff is perfect, but it seems to work.

... and the progress bar certainly much further away from that goal :)
The confusion of the noob, I saw a method though it was a class, did not see "self" in front of it. Yeap its definitely Zinc , its staring me in the face with that blank look :D Ok then its certainly my lack of understanding. I will take my time learning how Zinc works and how progress bar works. Will take a deeper look into how Monticello uses it. Thanks for the help, I should be able to figure this out. If not you will know it by the deep sounds I make when I hit my head against the wall.

Kilon, Here is another example: OrderedCollection streamContents: [ :out | [ ZnClient new signalProgress: true; url: 'http://stfx.eu/PharoV20.sources'; downloadTo: '/tmp' ] on: HTTPProgress do: [ :notification | out nextPut: notification. notification resume ] ]. The resulting collection has more than 1000 elements. So from the standpoint of Zn it works. What is then done with the notifications is another thing.

thank you again. Ok that shows clearly that ZnClient can perfectly stream its contents. I know it can do it, afterall Monticello is doing it, as soon as I figure out how Monticello is doing this , its should be a piece of cake. Assuming that there is such thing as "piece of cake" in coding :D Sven Van Caekenberghe-2 wrote
Kilon,
Here is another example:
OrderedCollection streamContents: [ :out | [ ZnClient new signalProgress: true; url: 'http://stfx.eu/PharoV20.sources'; downloadTo: '/tmp' ] on: HTTPProgress do: [ :notification | out nextPut: notification. notification resume ] ].
The resulting collection has more than 1000 elements. So from the standpoint of Zn it works. What is then done with the notifications is another thing.
Regards,
Sven

The confusion of the noob, I saw a method though it was a class, did not see "self" in front of it. Yeap its definitely Zinc , its staring me in the face with that blank look :D
Ok then its certainly my lack of understanding. I will take my time learning how Zinc works and how progress bar works. Will take a deeper look into how Monticello uses it. Thanks for the help, I should be able to figure this out. If not you will know it by the deep sounds I make when I hit my head against the wall.

Actually it works its just that is not meant to create a progress bar.
To create a progressbar I created a new test
testProgressBar UIManager default informUserDuring: [ :bar | [ ^ ZnClient new signalProgress: true; get: 'http://zn.stfx.eu/echo?delay=2' ] on: HTTPProgress do: [ :progress | bar label: progress printString. progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ]
it displays the progressbar , but it displays no progress (blue bar thing) and it close as soon as it finish the get. I tried to implement that in
createImageFromTemplate | name | name := UIManager default request: 'Image name?'. self showDownloadInProgress. [UIManager default informUserDuring: [ :bar | [ imageGroup extractTemplate: self selectedTemplate to: name] on: HTTPProgress do: [ :progress | bar label: progress printString. progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ]] on: PhLDownloadError do: [ :err | UIManager default alert: err longDescription. ^ self ].
self updateAll.
I assume that code is deeply flawed , hence why it does not display me any progressbar at all. Looks like I have a lot to learn.
First I am not sure if ZnClient downloads in packets and if it reports progress per packet . If its progress is upon success of download then it does not help at all , because in that case there will be only one stage of progress upon success of download. I want multiple stages of progress so the download bar increases from 0% to 100%(preferably per kb ). IF that is the cace then probably I will be better using the HTTP client of monticello to download the images which I know it works that way.
Is there a particular reason why we should stick to Zinc ?
The HTTP client of Monticello _is_ ZnClient, see MCHttpRepository>>#httpClient ;-)
Now, for performance reasons, progress in only signalled every ZnUtils class>>#streamingBufferSize which is currently 16K.
Apart from that, the download might go that fast that there is little to show.
I am certainly not claiming that the HTTPProgress stuff is perfect, but it seems to work.
I am open to suggestions :)

ah yes of course. Ok thanks for adding me.
I took a look at the code, it points back to Zinc , it look like I would need to override ZnClient >> withProgressDo: , no Idea how to do this currently but will continue looking into . I also found how monticello uses progress bars when downloading repos but it does not seem to use Zinc at all. So yeah this will take me quite some time to implement.
Progress is indicated by HTTPProgress Notification that are being signalled by the underlying code. You have to catch them and do something with them.
Have a look at ZnClientTests>>#testProgress
Although the example in the comment does no longer seem to work...
Its Fun none the less ;)

yeah I will give it a try, don't know how long will take me but I like what you have done with Pharo Launcher. I will create an enhancement issue when I have it working as I want and report back. Esteban has granted me commit right to pharo 3 inbox too so I will commit there. Or do you want me to contribute directly to smalltalk hub repo ?
I am new with pharo and morphic so please bare with me :)
the Pharo3Inbox is only for code integrated in Pharo itself. The launcher won't be integrated in Pharo. I added you to the project http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher

YEAH I DID IT !!! HAHAHAHA I am one of you now :D I Implemented the progress bar. Well it displays 2 progress bars. I assume the first one is for unzipping the file though it does not progress , could be something else. But the second one works like a charm , even displays the percentage of download and progress with each 1%. Beautiful and way way way easier than I expected , I just copied a method from monticello and had to add signalProgress: True to PHDownloader method that downloads the file via Zinc. So happy :D So now I am off to improve it, see if I can add progress also for unzipping the file and further improve the GUI. Ready or not here I come :D Thanks Sven for helping me out. I committed to the smalltalkhub repo, I have not added it to the Configuration because I want you guys to test it first to make sure I dont mess things up though I should not since I have not touched the existing methods apart from adding that simple message. So I dont know if you get the enhancement if you simply download the image. So go to monticello and get latest commit, you should see my name in there.

yeap definetly excited. I love python, but really missed such an IDE as pharo. But now I can say I found the tool I was always looking for. :) Ok tried , latest PharoLauncher on windows. Brogress bars work well, it even displays a third one for unziping the files. But I found a bug, it cant launch the image. Does not understand in ExternalWindowProcess >> value , nextPutAll:. There is however a comment inside the method that says : "FIXME: Close the initial pipe handles. For now, I have not implemented passing these to the child, and there is no support yet for nonblocking Windows OS pipes. Once those are available, this method needs to change to support." Is this why image launching fails, or is it unrelated ? btc wrote

Very nice. Works on Mint, too. Could use more feedback, maybe: It's not always clear when it's doing something when you create an image.
