Re: [Pharo-users] Pharo 7 image cannot write changes message on startup

Sanjay I have had messages like this when I inadvertently tried to start two copies of the same image (in my case pharo 6.1). The first image was running happily in the background, the second gave this message (but still seemed to start OK). I am also on Windows 10, using 32-bit Pharo.

pharo 6.1 64bit segmentation fault on linux
by Johan Brichau Jan. 13, 2018

Jan. 13, 2018

Hi, Iâm also hitting this issue: https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c… <https://pharo.fogbugz.com/f/cases/20737/Segmentation-fault-trying-to-load-c…> Also reported here: http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-… <http://forum.world.st/Pharo-6-1-64-bits-segmentation-fault-loading-code-on-…> This stops us from using Travis-CI because the OSX builds are just way too slow there. Since more recent vms are working (see thread), any chance the vm for linux is updated on the pharo site so we can use Smalltalk-CI? thx for an update Johan

Ben, (this is a bit off-topic) do you happen to know the purpose of that pre-debug-window? I must say that I find it annoying every time I get it in Pharo or VA? Why doesn't the debugger show up immediately? But your suggestion is a good one, imo. In the startup phase of an image, the image might not be ready to provide any means of reacting to a problem, so why bother showing errors that early? What you describe should be quite easy to achieve with a handler that records and resumes errors during startup.

Sean, I am not a regular Pharo user, so I have no code example for you. Just an idea: why not save an image copy instead of the image itself? Thus if an error occurs that might not happen at next startup (external dependencies etc.) , you couldÂ restart the "real image" and still use the failed copies to analyse your startup problems. I guess Pharo can do a "Save image as..." ? Joachim Am 08.11.2017 03:16 schrieb "Sean P.

[ANN] Python3Generator and MatplotLibBridge
by Julien Jan. 12, 2018

Jan. 12, 2018

Hello, My new year main resolution: stop keeping my side-projects for me. Itâs been like 1 year that I created these two projects, one coming from a refactoring of the other. Now it is time to take time to announce them. I initially come from Python world and during my bachelor & master, I really liked to use matplotlib to plot data using Python. So I wanted to be able to use this Python module from Pharo. I did it by generating Python 3 code from Pharo and making Python 3 executing it. So, first I implemented everything in MatplotLibBridge package and then I split it in two package in order to be able to eventually create bridges to other Python 3 modules. So, Python3Generator [1] is made for generating programatically Python 3 code from Pharo. Basically, it allows you to easily build a Python 3 AST, to serialize it in Python 3 source code and eventually to execute it. For now you can transfer data from Pharo to Python (e.g. providing arguments to functions that are Pharoâs objects) but you can not retrieve data stored in Python variable from Pharo (but it should be possible, just I donât need to do that for my bridge to matplotlib). Some examples are provided on the githubâs README. MatplotLibBridge [2] is made for creating plots using matplotlib [3] from Pharo. There is a bunch of examples of what you can do on the README. The two features from matplotlib I like the most are: 1. You can generate your plot in a lot of file formats (png, pdf, svg, ps, etcâ¦) 2. It allows to embed LaTeX mathematical formulae everywhere in the plot (which can be really cool). All the possible plots in matplotlib are not available in Pharoâs side because I build parts of the bridge when I need them but it is not hard to do. I someone is interested in a plot type not available yet, please tell me. So, it is announced, if someone want to do something with those, please do it! Happy new year.

Unresponsive/frozen Gui
by Andrei Stebakov Jan. 11, 2018

Jan. 11, 2018

I experience that issue once in a while when I leave the pharo 6.1 on windows and when I come back to it the UI is frozen. Now I download pharo with moose image and it started to happen again (BTW I couldn't install Moose in my pharo 6.1 using Metacello command) I wonder if it's something that happens to many users and I have to get used to it (ui freezes) or there ways to avoid it. Again, maybe it's a windows specific problem and most of the pharo users are either on Mac or Linux.

Hi, anyone used/uses Pharo to bind to ActiveDirectory? Last thread I've seen is http://forum.world.st/Pharo-amp-LDAP-td3308841.html Does it work now? Is http://map.squeak.org/package/ccbcb878-e09b-48ed-a773-5939bf8c2c3e the latest code is there something more updated? Thanks T.

Line feeds appearing in methods source code?
by Julien Jan. 9, 2018

Jan. 9, 2018

Hello, Itâs the third or fourth time that linefeeds appears in my methods source code while Iâm coding and I do not know whyâ¦ It happens on Pharo 6.1 and on different images. I am on MacOS and I am not copy/pasting code from the outside to Pharo so I do not understand why this happensâ¦ Anyone encounter the same thing?
