Re: [Pharo-users] Other format to Filetree

by Dale Henrichs

This is a good suggestion ... along these lines I've always thought that it would make a lot of sense to write a SmalltalkBrowser for Github in Amber of PHaroJS that would read Filetree package structure and display it the "right way" ... For extra credit one could even edit code in the browser:) And of course, the SmalltalkBrowser shouldn't be limited to just GitHub ... I wish that I had the spare cycles to do this:) Dale On 10/21/16 6:06 PM, Charlie Robbats wrote: > > I'd like to suggest you teach people Smalltalk natively, so they don't > get distracted by the false view of a filetree of classes.

If you copy an object then you have a second object and voyage will create a new one in the database. If you want update an object you need to update the object ;) and not a copy of it. If you have control of all the data updated in the UI then an approach like mementos might be appropriate. You can look at Magritte how it is done there. With immutable objects we'll have other options dealing with that.

[Voyage] Question about update of an object

by Cyril Ferlicot D.

Hi! I have an application with Users that are voyage roots. Those Users can have a object X that is also voyage roots. I created a web application where a User can create an object X and save it. But now I want to adapt the component to edit an existing X object. What I have in mind is that I can copy the instance of X, let the user change it and save the changes if the user click on "Edit" or discard the changes if it click on "Cancel". But I don't know how really works the update in Voyage. If I send "save" to the copy of X, will it replace X inside the DB? Or should I create a method "updateFrom:" in X to change all his variable to match the ones from the parameter and then send "save" to the real X object? Thanks -- Cyril Ferlicot http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

image shrinking and cleanup

by Peter Uhnak

Hi, I know that I can cleanup the image with `Smalltalk cleanUp: true except: {} confirming: false.`, however that doesn't seem to help much. My guess is that there are some objects that the system is permanently unable to GC, however I have no idea how to find them (or even where to begin the search). Just as a note, the size of the image by itself is not an issue (I have plenty of disk space), however it is severly slowing down image saving. I remember that there was some issue with image shrinking, but I am not sure what is the state of that. Oh, and I am using Pharo 5. Thanks, Peter

Re: [Pharo-users] Glamorous Toolkit as IDE for another language?

by serge.stinckwich＠gmail.com

Hi Luke, definitively a good idea. We are trying to do the same with Kendrick scripts in order to be able to run it from CLI and also in the image. We don't use Glamour at the moment but more the moldable tools like Playground+inspector.

Re: [Pharo-users] Glamorous Toolkit as IDE for another language?

by Dimitris Chloupis

Did you know that the creator of Smalltalk , Alan Kay , made Smalltalk not as the ultimate environment but as the basis of future environments? And it worked Eclipse for instance , the well known IDE, started as a Smalltalk implementation. I have done something similar with my Python bridge , it allow you to execute Python code from Pharo even using Pharo syntax and if there is an error it fires up the debugger displaying both the Python and Pharo error and even allows you to correct and re execute with ease from inside the debugger like regular Pharo code. I am not familiar with Glamourous Toolkit but I know moose people use it to build tools that analyze code in other languages like Java. SmaCC parser comes with a ton of support for existing languages, its what I used for my Python bridge to parse and convert Python data to Pharo ordered collections. The problem is that building IDEs is a rather painful process, so don't expect a magic button. So yes you can make he Lua IDE, but there is no library in Pharo that will make the IDE for you. Where Pharo suffers is in the text editing department , we cannot compete currently with emacs and vim but we are improving . It's possible to unify emacs or other external editors with Pharo. This way you won't have to remake something that already exists and you can use Pharo as an extension to this editors for example for live coding, code analysis, code visualizations, package installation etc areas that Pharo excels at. Emacs does support communication via sockets you can even take inspiration from Shampoo http://dmitrymatveev.co.uk/shampoo/ Sky is the limit here, you can do amazing things with Pharo if you have the time and desire.

Glamorous Toolkit as IDE for another language?

by Luke Gorrie

Howdy, I am interested in building a Lua IDE using the Glamorous Toolkit. The idea is that the Playground, the Inspector, the Spotter, and the Debugger would all be interacting with an external Lua process instead of running code in the Pharo image. The "under the hood" part of Pharo - Smalltalk code - would be hidden unless specially enabled. Good or bad idea? Any tips on how to approach this? Has something similar been done before? (Is there example code available?) Cheers, -Luke
