Re: Removing and object from an OrderedCollection in the inspector

by Noury Bouraqadi

In the the collection's inspector (left), in the bottom pane (playground) evaluate : self removeAt: 4. "Replace 4 with the index of element you want to remove" I suggest you work more in a playground you open from the "Browse" menu. Here is an example of what you can do: someEvent := "Code to get the event to delete". myEvents := OrderedCollection withAll: {"Your events here"}. myEvents remove: someEvent Noury -- https://PharoJS.org On Jan 12 2024, at 11:15 pm, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > > I am trying to remove some objects from an OrderedCollection in the inspector. > > I have class called Event.

Re: Updating objects in the inspector

by Noury Bouraqadi

Sergio, Welcome back to Pharo Smalltalk. The pane at the bottom of the inspector is a playground that has acces to the object instance variables. You can evaluate what ever expression you want. In your example, that would be name := 'New name' Noury -- https://PharoJS.org On Jan 12 2024, at 10:35 pm, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > Hi, all. > > I have been away from Pharo/Smalltalk for several years, but I am coming back to it now.

Re: Document layout with Pharo

Christian Haider has PDFtalk, originally in Visual works, but he and others have created ports to GenStone, Squeak, and Pharo. Bob Nemec created Report4PDF to make it easier to generate documents. Also, originally in VW, but also ported to GS, Squeak, and Pharo.

Document layout with Pharo

by Sergio Ruiz

Hi, all. I am looking to create a newspaper like listing of movie showtimes. Initially, I thought of using imagemagickâs annotate command to generate the output. Thinking further, I thought it might be worthwhile to generate a LaTeX file, and render that to a jpg. Then, I thought there might be a better way to do this natively in smalltalk. Does anyone have any idea how I might generate a document that can be converted to an image with a reasonable amount of control of the layout? Thanks!

Removing and object from an OrderedCollection in the inspector

by sergio ruiz

I am trying to remove some objects from an OrderedCollection in the inspector. I have class called Event. This has a class variable called Events which is a storage are for and ordered collection of Events. So, i inspected âEvent Eventsâ and I see my ordered collection. In the inspector, I select on of the objects, and I try to evaluate âEvent Events remove: selfâ.. But I am getting an error: an Event not found in OrderedCollection. Does anyone have any ideas on how iâd do this?

Updating objects in the inspector

by sergio ruiz

Hi, all. I have been away from Pharo/Smalltalk for several years, but I am coming back to it now. I am a senior developer, but havenât used smalltalk in any professional projects. I also found that I donât do ANY pet projects for fun anymore, as the current batch of languages/frameworks are not fun. They are effective and all. But not fun. I am starting a bunch of âscratch my own itchâ projects. Iâll be using Pharo as the data store, and maybe more. The thing I really want to do is document the usage of Pharo in my projects, and explain the toolchain, and why i chose each piece. My first project is to take a list of movie events from the local theater and create a listing reminiscent of the newspaper listings we read in the olden days. I have my models set up and figured out, but I have a really simple question. How do i change the value of an instance variable in the inspector. It looks like it should be super simple, but itâs not working. In this case, I am just trying to take the period out of a string. See that attached image.

Re: How to halt on Test errors?

by Denis Kudriashov

Hi David. Try to modify the method #runTestCase:results: to use "testCase suite debug" instead of #run: and you will switch to the debug mode. Then you can try to implement new command this way (copy ClyRunTestsFromClassesCommand as ClyDebugTestsFromClassesCommand and override some methods) Ð¿Ð½, 8 ÑÐ½Ð². 2024â¯Ð³.
