The package is "ConfigurationOfSeaside3-JohanBrichau.323.mcz" Yes that worked for me too. I then had to load my own project using the same API, so not: ConfigurationOfBetaNineT3 project bleedingEdge load: 'trackit'. But: Metacello new configuration: 'BetaNineT3'; version: #bleedingEdge; load: 'trackit'. This then loaded Bootstrap as needed (with Seaside already present). > This loads fine in Pharo 6 except that after installation the "Tools" -> "Seaside control panel" is not working anymore as > "NewListModel" is not found anymore. So the control panel is broken. Dont know what the migration path is for UI's > who used the removed "NewListModel" class. Here is how I quickly patched the control panel: WAPharoServerAdapterSpecBrowser>>#initializeWidgets self instantiateModels: #( listModel ListModel textModel TextModel toolbarModel WAServerAdapterToolbar). WAPharoServerAdapterSpecBrowser>>initializePresenter self initializeAdaptors. textModel aboutToStyle: false. listModel whenSelectedItemChanged: [ :selection | adaptor := selection. self updateUIState]; whenListChanged: [ self updateUIState]; displayBlock: [ :item | (item class name,' ',item statusString) asStringMorph ]; "icons: [ :item | self iconForAdaptor: item]; iconMaxSize: 16@16;" menu: [ :aMenu | self adaptorsMenu: aMenu]. self focusOrder add: listModel; add: toolbarModel; add: textModel. self disableAllButtons So I replaced NewListModel with ListModel and I commented out the icon related stuff.

Re: [Pharo-users] Which is the best way of opening a PDF and HTML local files from Pharo

by Offray Vladimir Luna CÃ¡rdenas

Thanks Hilaire. I was thinking in something that depend on OSProcess and invoke xdg-open on Linux, for example, but is not working neither. OSProcess command: 'xdg-open ', pdfPathString doesn't open the PDF file :-/.

Re: [Pharo-users] Which is the best way of opening a PDF and HTML local files from Pharo

by Hilaire

Oh, you can add your extension to the OSPlateform hierarchy. So one your extensions added in the hierarchy, your code will use it with an uniform: OSPlateforme current openPdf: 'grafoscopio.pdf' Le 24/02/2017 Ã 18:55, Hilaire a Ã©crit : > But likely there is already something like that in the system but I > can't see. -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Which is the best way of opening a PDF and HTML local files from Pharo

by Hilaire

Hi Offray, You may want to do it with a hierarchy of classes, one for each host, to handle concretely the PDF and HTML OS viewer you want to use, and another class to handle it uniformly. For example MyOperation>>openPdf: aFile then it will delegate to LinuxOperation/WindowsOperation/MacOperation depending on the host running the VM. That way you could add up more operation when needed. But likely there is already something like that in the system but I can't see.

There is a better way to open such files from several platforms? -- Dr. Geo http://drgeo.eu

Grafoscopio User Manual: Early beta

by Offray Vladimir Luna CÃ¡rdenas

Hi all, I'm making a couple of articles for the JOSS[1], which, by the way is an interesting critic/hack to the anachronistic published paper on indexed journal[2], making visible the work of research who use mainly software as a medium to communicate and make research. [1] http://joss.theoj.org/ <http://joss.theoj.org/> [2] http://joss.theoj.org/about JOSS proposes a pretty good structure for the companion readme file for the software. I started to write it, but I entered to some kind of "writing frenzy" and, after almost 40 pages(!), it ended in the English Grafoscopio User Manual: http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma… <http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/En/Books/Manual/ma…> Is the first text I write of such length in English, so any critic on typos, clarity or others are welcomed. Please see the "Community Guidelines" section, particularly "Report issues or problems", so I can follow and address the suggestions better. I will be making some minor updates on the software and the manual to improve consistency (manual URL, remains the same, pointing to the last version). Cheers, Offray <http://joss.theoj.org/>
