Imagine that instead of having a website or a book or a pdf somewhere you would have a more live version directly in the image that you could interact with. An extremely crude example: â Creating something like that is currently quite awful: ``` window := SystemWindow new. window addMorph: (RubScrolledTextMorph new beWrapped; yourself) frame: (0@0 corner: 1(a)0.2) window addMorph: (SpecWindow allInstances detect: [ :each | each identityHash = 330624768 ]) frame: (0(a)0.2 corner: 1(a)0.4) window addMorph: (RubScrolledTextMorph new beWrapped; beForSmalltalkScripting; yourself) frame: (0(a)0.4 corner: 1(a)0.6) '/tmp/pharo.png' asFileReference binaryReadStreamDo: [ :stream | window addMorph: (PNGReadWriter formFromStream: stream) asMorph frame: (0(a)0.6 corner: 1 @0.8) ]. window addMorph: (RubScrolledTextMorph new beWrapped; beForSmalltalkScripting; yourself) frame: (0(a)0.8 corner: 1@1). window submorphs second push. window openInWorld. ``` Also I've just realized that on ESUG someone (Andrei I think) was showing something like this running on Blocâ¦ but I have no memory what it was called.

If you just want to execute code (similar to the old Workspace) then you can just use Rubric. | textMorph | textMorph := RubScrolledTextMorph new newScrolledText. textMorph beWrapped; beForSmalltalkScripting. textMorph openInWindow extent: 432@432.

embedding images inside Playground

by Peter UhnÃ¡k

Hi, is it possible to somehow embed images (Form) inside Playground? The use case is a kind of in-image help or guide where one could also execute code, but there would be also example images. Or maybe have a container Morph that would contain Playground? Is that possible? Thanks, Peter

No real progress here. The binding was/is quite complex - so I used a simpler serial interface over usb instead of the full native implementation.

Hi, Thanks for looking at this.

The help lists: GTSpotter - Examples (gtSpotterExamplesFor:) - Catalog Projects (spotterCatalogProjectsFor:) - Clipboard History (spotterClipboardFor:) - Methods (spotterConcreteMethodFor:) - Dirty Monticello packages (spotterDirtyMonticelloPackagesFor:) - Playground cached pages (spotterForCachedPlaygroundPagesFor:) - Classes (spotterForClassesFor:) - Directories (spotterForDirectoriesFor:) - Calculator (spotterForExpressionsFor:) - Files (spotterForFilesFor:) - Global variables (spotterForGlobalVarsFor:) - Help topics (spotterForHelpTopicFor:) - Messages (spotterForMessagesFor:) - Metacello Configurations (spotterForMetacelloConfigurationsFor:) - Packages (spotterForPackagesFor:) - Pragmas (spotterForPragmasFor:) - References (spotterForReferencesFor:) - Monticello Repositories (spotterForRepositoriesFor:) - Senders (spotterForSendersFor:) - spotterForStashedPlaygroundPagesFor: (spotterForStashedPlaygroundPagesFor:) - History (spotterHistoryFor:) - Implementors (spotterImplementorsFor:) - Moose Models (spotterMooseModelsFor:) - ws.stfx.eu (spotterStfxFor:) - Menu (spotterWorldMenuFor:) All of these, can be used with #.
