[Ann] OSSubprocess 1.0.0

by Guillermo Polito

Hi all, News from the OSSubprocess side. For those who do not know it, OSSubprocess is the library to call external processes from Pharo. These are the main points of this release. - 64bits support - Issues Working on both Pharo 6 and 7 - Issue #34: Adding tests to validate that the return code is correctly handled - Issue #27: Cleanup: remove OSSubprocess-Tests package - PR #26: Add stress tests This version works for Pharo >=6. Users of Pharo5 will need to stick with v0.2.5, because of non compatible changes in uFFI (required mostly for 64 bits). Additionally: - We moved the repository to pharo-contribution to remove pressure from Mariano for releases and integrations - We updated the configuration in the catalog - We decided to move to a 1.0.0 versioning schema because 0.* does look like the library is not stable and it actually is (We have been using it in pillar and iceberg for quite some time). You can load this version from the catalog or using with: Metacello new baseline: 'OSSubprocess'; repository: 'github://pharo-contributions/OSSubprocess:v1.0.0/repository'; load. Detailed changes log in - https://github.com/pharo-contributions/OSSubprocess/releases/tag/v1.0.0 - https://github.com/pharo-contributions/OSSubprocess/compare/v0.2.5...v1.0.0 If you have any issues (or PR!), we wait for your issue entry in https://github.com/pharo-contributions/OSSubprocess/issues Have a nice weekend, -- Guille Polito Research Engineer Centre de Recherche en Informatique, Signal et Automatique de Lille CRIStAL - UMR 9189 French National Center for Scientific Research - *http://www.cnrs.fr <http://www.cnrs.fr>* *Web:* *http://guillep.github.io* <http://guillep.github.io> *Phone: *+33 06 52 70 66 13

[Errors] email on error?

by sergio ruiz

Is there Â a way to send an email on an error or exception? I have an app that runs live on a remote server, and I am finding that every now and then, the server will lock up, and I wonât know whatâs going on with it. Currently, i pull the image and run it local, but an email with a stack trace would be SUPER helpful. Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Re: [Pharo-users] Showing Keyboard events as Pharo goes weird when using an RD client for OSX

by Tim Mackinnon

Actually - I installed VNC on Linux server and itâs much faster and doesnât have this issue . I think for keyboard events I would have had to create a morph and then override some handle key events to print them out ?

With the latest Iceberg (with the 'Repair ...' technology), you get a similar experience (I know you wrote your tool earlier). You can also do the PR in Pharo itself now (but doing in the Github web UI is OK too). Sven

Showing Keyboard events as Pharo goes weird when using an RD client for OSX

by Tim Mackinnon

Hi - Iâm wondering if anyone has any experience using Pharo in a Remote Desktop environment? Ive been experimenting with MacInCloud.com and running Pharo there - however Iâve noticed that while it appears to run (and it reasonably performant) after a few seconds/minutes (I canât quite work out what causes it) certain keeps stop working - most importantly the Enter key (but also Cmd-P etc). It looks like its dishing out some kind of tab key (its invisible in the playground - the cursor just jumps forward a few characters) but Iâm not sure, and I wondered if I could print out key codes in Pharo to maybe spot what it is. But keyboard handling is not something Iâve dug into - and Iâm looking for a few pointers (or maybe someone has seen this problem before and might be able to suggest a solution). As I said, It starts out ok but then suddenly swaps to this behaviour (which makes coding then impractical). Restating the RD client doesnât make a difference (and Iâve tried 2 different ones now). Other remote mac apps like Notes donât seem to be affected and I have to exit the image and come back in to correct it. (I havneât tried saving in between to see if it then preserves this behaviour). Ulimately I was hoping to have an easy portable Pharo environment to sneakily take on holiday via an iPad. The approach is to try and compile Pharo for iOS (I did it a long time ago, but it was a pain - whereas a remote server seemed like a neat solution). Tim Sent from my iPhone

Hi Henrik, As I have very limited knowledge on network stuff, to get started, do you have simple example code to show how to use your package?
