Re: [Pharo-users] STON: Metadata of text and yaml translations

by Tudor Girba

Hi, In your case, you probably do not need to store text (this is what gets in the #text port) but the string correspondent. Just use "text asString" before you store the updated text in your object.

Re: [Pharo-users] Zoomable & Infinitely scrollable PasteupMorph

by Alexandre Bergel

Yes it can. But Roassal is not made to replace Morphic. In my opinion, Morphic is not simply about having graphic elements answering events, as Roassal does. Morphic provides ways to build sophisticated UI (even if Morphic behaves poorly in comparison with state-of-the-art UI frameworks). Roassal is made to visualize and interact with data. As it is defined today, Roassal is not made to build sophisticated UI.

Voyage, selectMany with multiple Root

by gonza

Hi people, I've been making a small project using Pharo and Voyage, and everything is going well, but I'm facing a performance issue when retrieving items from Mongo. I've two classes, one for items, and other for users, and both are Root. Each item contains the user who created it. My question is if there's a best way of querying all items for an user, using selectMany, when you have a document containing another. As work-around, by now, I'm making a selectAll and then filter them on memory, and that takes a lot of time and memory when the collection grows. Can you help on this? Thanks, Gonzalo -- View this message in context: http://forum.world.st/Voyage-selectMany-with-multiple-Root-tp4778705.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

You can override/reimplement #toSton: and #fromSton: (check the other implementors) to customize how your objects are handled. Looking at your example, I don't really see the problem, you used Text instances, so they are serialized as such. This way, potential styling is preserved. > 2.

STON: Metadata of text and yaml translations

by Offray Vladimir Luna CÃ¡rdenas

Hi, Finally, with help in the Moose mailing list (thanks Doru!), I have automatic update of nodes in my outliner, and its working pretty well. I'm using STON for persistence and I see that when I update a node body content I got a lot of metadata on the text like runs, text font, text color, lastIndex, lastOfset. For reference I have attached two files, test.1.ston which is the original outline with no updates on nodes and test.2.ston which contains the updated nodes with metadata. So my questions are: 1. There is any way to exclude the text metadata or to select the "deepness" of the exportation, including just the content of the text, but not the metadata of it? 2. I see that there is a way to export from STON to JSON. There are plans to implement something like YAML[1] export? If not, which would be a good approach to explore the existing code on STON-Core and implement this? 3. I have seen that text string containing a carriage return are stored with "\r" character in them, there is any way to make the text be stored containing actual carriage returns?
