Re: [Pharo-users] gtdebugger in pharo 5.0

by Tudor Girba

Hello everyone, As expected, there was some feedback. Here is a summary: 1. The layout should mirror the classic debugger - The previous layout was chosen to show more of the stack and to make use of the screen real estate. - But, as that is not an essential component of GTDebugger, the current implementation of the generic stack debugger looks like this now: 2. it would be interesting if the buttons would have text - This is something we need to work on 3. Why is there bytecode shown? - There is none by default :). This only appears when the developer explicitly chooses the Bytecode debugger 4. why is there a _thisContext _stackTop? - Because this is what the SpecDebugger offers as well :). - But, we removed them for now from the list. - There would be a possibility to add them to the context menu of the stack or to add them to bottom of the list 5. why is there a Type column in the inspector - Because we want to know what kind of variable we are dealing with (parameter, instvar, temp). This is not explicit in other debuggers. - Furthermore, you can filter the variables by clicking on the type tag. This can be particularly useful when we deal with large states. Please let me know if I missed anything. Of these only point 2 requires work.

I propose this as an exercise. Now I was not aware that we have doubleLinkedList in the system.

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

by Offray Vladimir Luna CÃ¡rdenas

Hi, Lets try something simpler. Consider this code: ============================= | data m1 m2 | data := { 'first' -> 'I\"m just text' . 'second' -> 'ProfStef openPharoZenWorkspace'} asOrderedDictionary. m1 := DynamicComposableModel new. m1 instantiateModels: #(list ListModel). m1 list items: (data keys). m1 layout: (SpecLayout composed add: #list; yourself). m2 := DynamicComposableModel new. m2 instantiateModels: #(right TextModel). m2 assign: m1 to: #left. m1 list whenSelectedItemChanged: [:item | item ifNil: [ m2 instantiateModels: #(right TextModel). m2 right text: '' ] ifNotNil: [ item = 'first' ifTrue: [ m2 instantiateModels: #(right TextModel). Transcript show: m2 right asString, String cr ]. item = 'second' ifTrue: [ m2 instantiateModels: #(right GlamourPresentationModel). Transcript show: m2 right asString, String cr]. ] ]. m2 layout: (SpecLayout composed newRow: [:r | r add: #left; add: #right]; yourself). m2 openWithSpec ============================= Shouldn't be #right dynamically defined according to the values of 'item' and be replaced on the m2 layout? The transcript show that anytime I change the selection in this small spec interface, m2 right is changed. Is it not what I'm putting in the right side of the interface with the line which says: "newRow: [:r | r add: #left; add: #right];" How can I made spec in this small example show the respective value in the dictionary when the key value is "first" inside a TextModel and the respective value in the dictionary when the key value is "second" inside a GlamourPresentationModel?

Hi Johan, I have not found more errors on the booklet, but I think that I'm not getting the explanation of dynamic spec. Consider this code: ============================== GrafoscopioGUI Class>>exampleBootstrapDynamicUI "Starting from an example UI from the Spec-Glamour, to customize towards the grafoscopio UI and get some ideas" |notebook leftUpperPanel leftPanel treeBrowser | "Creating a notebook-tree with dummy data" notebook := GrafoscopioNode new becomeDefaultTestTree. "Defining the tree roots part" leftUpperPanel := DynamicComposableModel new. leftUpperPanel instantiateModels: #(tree TreeModel). leftUpperPanel tree roots: notebook children; childrenBlock: [:node | node children ]; displayBlock: [:node | node title ]. leftUpperPanel layout: (SpecLayout composed add: #tree; yourself). "to debug upto here uncomment the next line, and comment all other 'openWithSpec' ones" "leftUpperPanel openWithSpec." "Integrating the previous tree with the node header and creating the body according to the tags on the node" leftPanel := DynamicComposableModel new. leftPanel assign: leftUpperPanel to: #roots. leftPanel instantiateModels: #(header TextInputFieldModel). treeBrowser := DynamicComposableModel new. leftUpperPanel tree whenSelectedItemChanged: [:node | node ifNil:[ leftPanel header text: ''. treeBrowser instantiateModels: #(body TextModel). Transcript show: 'Nada que mostrar', String cr] ifNotNil: [ leftPanel header text: (leftUpperPanel tree selectedItem content header). leftUpperPanel tree selectedItem content tags = 'cÃ³digo' ifTrue: [ treeBrowser instantiateModels: #(body GlamourPresentationModel). Transcript show: 'I am code', String cr. Transcript show: treeBrowser body asString, String cr. ] ifFalse: [ treeBrowser instantiateModels: #(body TextModel). treeBrowser body text: (leftUpperPanel tree selectedItem content body). Transcript show: 'I am NOT code', String cr. Transcript show: treeBrowser body asString, String cr. ] ] ]. leftPanel layout: (SpecLayout composed newColumn: [:column | column add: #roots; add: #header height: 35]; yourself). "Integrating the previous tree with node body content" treeBrowser assign: leftPanel to: #leftTree. treeBrowser layout: (SpecLayout composed newRow: [:r | r add: #leftTree; add: #body ]; yourself ). treeBrowser openWithSpec. ============================== I can get the interface shown here: and when I move between nodes in the upper left tree the correspondent name in the lower left input box changes accordingly, but nothing else happens on the right side panel. I have put the definition of the type and contents of such panel inside a whenSelectionChanged block, as you can see in the previous code, because I think that right panel should change according to the type of node that is selected, but this doesn't work. The debug info that I send to a transcript show that #body becomes a GlamourPresentationModel or a TextModel depending on which node I'm selecting. I don't know what I'm doing wrong or how this dynamic spec is supposed to behave... well, dynamically, and accordingly making layout components to change on the fly. How can I make the right panel change to become a GlamourPresentationModel or a TextModel in Spec-Glamour? Thanks, Offray On 08/01/16 12:10, Johan Fabry wrote: > > Consider the error as reported!
