Re: [Pharo-users] Problem cleaning up image

by Vitor Medina Cruz

Ok, I did some extra tests and I think I figured what is happening: the code I load on the image subject to clean has a startUp method that starts a Teapot server on port 8080. I tried various scenarios: 1- Load a fresh image from get.pharo.org and execute clean --> Ok 2- Load a fresh image from get.pharo.org only with the dependencies from my project (ConfigurationOfTwitterChallenge), one at a time, and execute clean --> Ok 3- Load a fresh image from get.pharo.org, apply ConfigurationOfTwitterChallenge and execute clean --> Fail 4- Load a fresh image from get.pharo.org, apply ConfigurationOfTwitterChallenge and execute eval "TwitterChallengeMain stopDefaultExecution. ImageCleaner cleanUpForProduction. Smalltalk snapshot: true andQuit: true." --> *Ok *(Assuming ImageCleaner cleanUpForProduction. Smalltalk snapshot: true andQuit: true. does the same as clean --production) It appears I cannot clean an Image with the server started. Question: is that an error or I really should not try to clean an image with a server on? If the former I open an issue on FogBuz and I will try on a not-headless vm to see if some error happen.

Hi Holger, I think your scenario is not covered by Iceberg. It could be a nice feature but not one of the most important. Nicolas will answer but I think he focuses on most common scenarios. In my case, what I miss is to be able to choose what I want to commit. Nicolas already planned to add this.

Hi Brad, all forms can be shown as part of a Spec UI. Thereâs the ImageModel for that. For example, supposing you have an âiconâ instance variable in your UI, add to initializeWidgets: icon := self newImage. icon image: (#thumbsUp asIcon). HTH -- Does this mail seem too brief?

Spec - Display an ICON without dropping to Morphic

by Brad Selfridge

I want to create a MessagePrompter widget that will display either and error, warning, or information message. I want to display a different icon associated with each message type. Is there a way to do this in Spec without having to drop down into Morphic? I do NOT want to have to learn Morphic.
