Re: [Pharo-users] Problems with auto-updating the text of a playground

by Tudor Girba

Hi, I am not quite sure I understand your problem, but I believe what you want is to only react to a change in a text. This information is placed in the #text port. Here is a basic example of how to react to it: http://ws.stfx.eu/ETEC2JH7363M Cheers, Doru > On Feb 6, 2017, at 2:16 AM, Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> wrote: > > Hi, > > For my Grafoscopio notebooks, I have implemented a way to auto-updating the content of a node, so it is automatically saved in the notebook when a node content is changed.

Problems with auto-updating the text of a playground

by Offray Vladimir Luna CÃ¡rdenas

Hi, For my Grafoscopio notebooks, I have implemented a way to auto-updating the content of a node, so it is automatically saved in the notebook when a node content is changed. The problem is that a node contains an embedded playground that produces text as output when executed (for example the playground reads a file or scraps HTML or calculates a hash), the text of the playground is replaced with the executed output. If the playground produces a visualization or non-textual output, this doesn't happen. I imagine that the source of the problem is here: ======= GrafoscopioNotebook >> autoSaveBodyOf: aNode body body class = TextModel ifTrue: [ body body whenTextChanged: [ :arg | aNode body: arg ] ]. body body class = GlamourPresentationModel ifTrue: [ | playground | playground := body body glmPres. playground when: GLMContextChanged do: [ :ann | ann property = #text ifTrue: [ | playgroundText | playgroundText := (playground pane ports at: 2) value. aNode body: playgroundText ] ] ] ======= as you can see the "when: GLMContextChanged" updates a node body with the playgroundText, as intended, so I can capture any change of the playground code, but I would like to add some condition to **not** update the body content if the text is the result of a playground execution. There is any way to do this? Thanks, Offray

Re: [Pharo-users] Chronos Manager Singleton

by Dimitris Chloupis

Very interesting read Ben thanks for sharing By the way I added the singleton and I optimised the loading of some image files. More optimizations will follow the next weeks. So now you should not be annoyed with multiple instances of ChronosManager Thank you all for your interest in ChronosManager :) On Sun, Feb 5, 2017 at 3:17 PM Ben Coman <btc(a)openinworld.com> wrote: > On Sun, Feb 5, 2017 at 8:32 AM, Cyril Ferlicot D. > <cyril.ferlicot(a)gmail.com> wrote: > > Le 05/02/2017 Ã 01:08, Dimitris Chloupis a Ã©crit : > >> The initial intention was to not make it a singleton to allow for > >> multiple instances of timers.

Re: [Pharo-users] visualizing ConfigurationOf dependencies with GTInspector?

by Tudor Girba

Hi, The dependencies extensions are available in the ConfigurationOfGTInspector (or in the Moose image). You have to inspect a version object: Cheers, Doru > On Feb 5, 2017, at 4:51 PM, Peter Uhnak <i.uhnak(a)gmail.com> wrote: > > Hi, > > maybe I was dreaming but I thought I saw somewhere that GTInspector could show the dependencies and groups in ConfigurationOf classes.

visualizing ConfigurationOf dependencies with GTInspector?

by Peter Uhnak

Hi, maybe I was dreaming but I thought I saw somewhere that GTInspector could show the dependencies and groups in ConfigurationOf classes. Does something like that exist? (Obviously when I inspect any such class it doesn't show it). Thanks, Peter

loading Icerberg repo with dependencies

by Peter Uhnak

Hi, I finally started to move to Pharo 6, so now I can play with Icerberg... my question is: how can I load a repository with all its dependencies? In other words... can I tell Icerberg that for the given Ice Repository to execute BaselineOf? Or is the use case: 1. use metacello to load project (with all dependencies) 2. add all Ice repositories 3. load all code again (this tima via Iceberg) 4. (optionally) remove all previous metacello repositories to avoid confusion Thanks, Peter
