Re: [Pharo-users] Pharo for Data Visualization

by Dimitris Chloupis

its possible via my Ephestos project, to render to video or real time but the project is still very much a WIP. Its doable but require some python knowledge and knowledge of Blender UI and API. I will be making a true Pharo API for it fairly soon but as you can imagine these things take time.

Spec on Moose 6.0 error: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

Indeed. The GTInspector and Spotter shows you how to navigate inside such zip files, too :).

Monticello MCZ files are zip files. Just rename the extension to ZIP and unzip it and you'll see multiple files and a directory containing a file. So intuitively I'd say ZIP in Pharo must support directories - not that I know how :) cheers -ben On Sat, Nov 21, 2015 at 4:16 AM, Juraj Kubelka <juraj.kubelka(a)gmail.com> wrote: > If I remember well, ZIP in Pharo supports only one file (one stream of data).

The code you'll be using is the one Metacello uses for its github and bitbucket urls, so I think it should handle it. The Metacello example is just: extractRepositoryFrom: zipFile to: directory "unzip <zipFile> into <directory>" ZipArchive new readFrom: zipFile; extractAllTo: directory asFileReference. As simple as that. So testing will be easy. Note that MetacelloPlatform also has the OSProcess-based unzip as well ;) >> >>> I do not stand on using *.tar.gz, but I have not found better >>> solution for my setup: Directory is compressed on Linux machine >>> and should be extracted on any machine by using local tools. >>> >>> Do I miss some feature in Pharo? >> >> I think you do ;) > > Better :-) Tell us how it goes anyway ;) Thierry > Cheers, Juraj >

However I think the zip Filesystem doesn't work which means you have to manipulate the zip members with the zip API, not as a filesystem. Can you give me an example? The file has about 30.000 files (compressed less then 50 MB).
