EXIF / JPEG metadata

Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Pharo 6.0 and 6.1 64 bit freeze on MacMini
by Ted F.A.van Gaalen Jan. 27, 2020

Jan. 27, 2020

Hi, I reverted to 5.0 because Pharo 6.0 and 6.1 64 bit hangs on my Mac Mini with UDH 4K screen (may that has to do with?) with its maiden image (at first start after download when: I resize or go to full screen. Maybe VM problem? my mac Mini metrics: Hardware Overview: Model Name: Mac mini Model Identifier: Macmini6,2 Processor Name: Intel Core i7 Processor Speed: 2,6 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 4 GB Boot ROM Version: MM61.0106.B1F SMC Version (system): 2.8f0 maybe this problem was already reported, but could find it. Kind Regards TedvG

Namespaces (was Re: Behold Pharo: The Modern Smalltalk)

It seems the > only questions have been: 1) how to do them *right*, The default position would be leveraging someone else's experience, so this begs the question, what is wrong in namespace implementations in VW, Gemstone, Squeak (as our immediate neighbours, then plus Dolphin, SmalltalkX, other languages) Are there been any research papers around comparing these? I found the "Pharo on Gemstone VM" talk impressive. The "develop on Pharo deploy on Gemstone" philosophy seems like a nice synergy for Pharo's commercial future. So a naive approach would be to do namespaces just like Gemstone. Maybe its not the best, but would it be "good enough" -- perfection being the enemy of done and all that jazz. cheers -ben > and 2) where they fall on the endless prioritized todo list >

Parsing in VW
by Steffen MÃ¤rcker Dec. 3, 2019

Dec. 3, 2019

Dear all, I have two questions regarding parsing frameworks. 1) Do you have any insights on the performance of SmaCC VS Xtreams Parsing VS PetitParser? 2) Has anybody started to port PetitParser 2 from Pharo to VW? Is it worth the effort? Sorry for cross-posting, I thought this might interest both communities. Cheers, Steffen

Microsoft COM

Hi Pablo, At work I managed to remote control Internet Explorer with Excel VBA like this... [1] http://www.automateexcel.com/vba/automate-internet-explorer and went looking for how similar might be achieved from Pharo. IIUC I discovered this would be done via Microsoft's Component Object Model, and then I bumped into your repo... [2] https://github.com/tesonep/pharo-com Could you advise the status and your plans for this? Since I see its only a few months old I've probably stumbled onto it prematurely, but I see no documentation or tests to discover how to use it. So I'll curious whether it makes something like [1] possible? And could you show how that would be done? cheers -ben P.S. For context, at work I automated IE since the intranet document management system (OpenText) does authentication via a javascript function in the browser, which doesn't compute with Microsoft's MSXML.DOMDocument component. So I use IE to do the authentication and grab the raw XML from IE to then stuff it into MSXML.DOMDocument from which I pull the data I need. But I'd love to do it with Pharo instead (if I can get IT to white list it) cheers -ben

Right clicking often fails first time?
by Tim Mackinnon May 20, 2019

May 20, 2019

This has been bugging me for a long time - but its incredibly annoying that when you right click on a class, package, Iceberg entry - that the context menu doesnât often appear. You have to click again (or remember to click first and then right click - even if the reverent item is already highlighted). Why is this? Is it a bug worth reporting and seeing if it can be fixed (or is it just me? This is in 703, OSX High Sierra) Tim

Getting example images - https://picsum.photos

Hi, This is a cool service: https://picsum.photos - it gives you example images (pictures/photos). Here is how you can use this from a standard Pharo image (no pun intended). ZnEasy getJpeg: 'https://picsum.photos/512'. ImageReadWriter formFromStream: (ZnClient new systemPolicy; url: 'https://picsum.photos/640/480?grayscale'; accept: ZnMimeType imagePng; get) readStream.

Why doesn't the VM command line help show the useful image commands anymore?
by Tim Mackinnon May 1, 2019

May 1, 2019

I was asked a question about starting pharo exercism from the command line on Arch linux - seems the Pharo.image file isnât being found (but it was installed with AUR, which I am unfamiliar with). Anyway - I tried using the command line on OSX ( I noticed they had used pharo, and not pharo-ui â which I never understood: why is it not pharo for ui and pharo-cmd for terminal, as it burns most people?) - and typed âpharo âhelpâ, and you get an impressive long list of commands - however it doesnât show you the useful Image commands anymore? So you would never know to use âpharo Pharo.image âlistâ. A while back it showed you that - but its now gone which seems a shame? I also notice at the bottom of the list, its says the the image name defaults to Pharo.image - however I havenât noticed that works at all - you have to specify an image, so thats a bit misleading.

Runaway scrolling in Pharo 7 on Ubuntu 18.04
by Pierce Ng May 1, 2019

May 1, 2019

Anyone encountering runaway scrolling in Pharo 7 on Ubuntu 18.04-based systems? In Pharo 7.0.3, click Help > Glamour Example Browser. When the browser comes up, click Fast List Outline Simple on the left pane. In the right pane's Browser tab, click inside the scrollbar's gutter, i.e., not on the end arrows nor on the positional brick. The list doesn't stop scrolling until it reaches the bottomest entry. In the code browser, it happens in the bottom code pane but not in the other panes. This happens on my laptop running Xubuntu 18.04 and also in VirtualBox VMs running Xubuntu 18.04 and Lubuntu 18.04 on my Mac. It does _not_ happen on the Xubuntu 18.04 laptop when doing the same in a 60546 image. It does also happen running a current Pharo 8 snapshot image; no Glamour Example browser built in but I get the same scrollbar behaviour in a Form inspector window. It does _not_ happen when doing the same in a 7.0.3 image in a VirtualBox VM running a LinuxMint version that is based on Xubuntu 16.04. Pierce
