You mentioned that workspace is not the only place where to work. One can work also in the debugger or in the browser. Yes - but a playground is also not the only place where I play with objects. Some people love to play with their objects in the debugger, browser, script manager, or elsewhere... Â >Yes, I use the playground extensively for so many use cases.

Sorry could'nt resists ;) I stand with my point: the playground is too close to the existing concept of a Workspace to deserve a new name. At the opposite tools like "Spotter" really introduce something conceptually new. Bye T.

Great! Thanks a lot for doing this. At this moment, you cannot add more than one action. It's hardcoded, but we want to extend that part as well. We just did not get to do it yet.

Applying GTSpotter to domain objects, an experiment

by Stephan Eggermont

GTSpotter looks like a nice way to build end-user applications too. An address book is a simple example of that, with parties and addresses Clear the address book ABAddressbookModel reset. Add someone ABAddressbookModel default addFirst: 'Stephan' last:'Eggermont'. Add a telephone number to someone ABAddressbookModel default parties first addTelephone: '+31-6-55555555'. Open a spotter on the address book GTSpotterMorph new width: 400; doLayout; spotterModel: (GTSpotter on: ABAddressbookModel default); openCenteredInWorld How do I add actions to add a person/address, edit it, or remove it? I can see how I can add one action, can I add multiple? Stephan

Re: [Pharo-dev] [Esug-list] [Pharo-users] [ann] gtspotter: a moldable interface for spotting objects

by Johan Fabry

OK now I get it â¦ thanks for clarifying! I think my confusion stems from the use of âcategory' and then talking about 'the collection objectâ, which made me think about collections and source code and protocols and packages and I got lost. I think that the sentence of the blog would be clearer like this (uppercase to show changes): To do this, GTSpotter offers an extra action: diving in a RESULTS category. Pressing Cmd+Shift+ArrowRight dives in the collection OF RESULTS OF that category. Thus, we can continue refining the search inside the category. So then, my suggestion for a legend at the bottom of the results list would be: Cmd+Shift+ArrowUp/ArrowDown = Next/Prev category, Cmd+RightArrow = Dive into Result, Cmd+Shift+RightArrow = Dive into Category > On Dec 8, 2014, at 12:48, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Hi, > > Ok.

If you're just going to use .xlsx files, it might be possible to unzip the file and peek the xml representation of that table (not that I've done it though). By unzip the file you actually see the xml, but I will complicated to use the values of the formula cells and to differentiate the sheets... If you're going to support .xls / Excel < 2003 files, you will probably need a COM-bridge. I remember that I've seen it for Squeak in the past, I don't recall having seen it for Pharo. It is only Excel > 2003. Another kind of hackish solution could be setting up an ODBC driver for Excel files and then using DBXTalk/ODBC or the ConfigurationOfODBC-based package. I have tried. But when I launch the DBXTalk tests it asked me to choose a DBXODBX*Facility... Which one should I choose? Should I install some plugins? And in ConfigurationOfODBC there is no tests and doc so I don't know how to launch it... I heard about OLE (Object Linking and Embedding) to interact with Windows objects.

Re: [Pharo-dev] playground vs workspace

>And Playground would match so well the marketing term of "playing with live objects". Sorry - but to me it looks like you were catched too much into: now we have to be more modern or rival with all this "lively" stuff (Lighttable IDE, Apple Swift, ...). We all know that being "lively" is something Smalltalk had already years ago and in the best way one can do it. >You might say that Playground is not the only place where people can play with objects, but Same argument against Workspace is an argument against Playground then.

Re: [Pharo-dev] [Esug-list] [Pharo-users] [ann] gtspotter: a moldable interface for spotting objects

by Tudor Girba

Hi, Ok. Let's take it step by step and see if we cannot find a better way of explaining. Take a look at the first picture in the blog post. Entering GTSpo shows results both for Classes and for Packages. These "Classes" and "Packages" are what we call search categories, and they have associated a query processor that can populate them with results (see the "Spotting your objects" section from the bottom of the post). In our case, we get 39 classes (of which only 5 are shown) and 1 package that match the query. If you want to look at all those 39 classes, you can dive in the whole collection behind the category in a separate step. This is achieved through Cmd+Shift+ArrowRight. Does it make more sense now? I did not consider the category to be confusing. Would you propose another name?
