Re: [Pharo-users] openstreetmap + roassal

by Nicolas Lusa

Hi, sorry for the late response. I tried to debug it on my own and got to some point where it seems it works. I had some complains when it was parsing at first and then some issues with the openstreetmap server I guess. I'll check the tutorial to and try to fix it and make it as smooth as possible. Thanks a lot for the hints.

I am currently working on my master thesis and I am getting into pharo, playing around a little bit and tasting the potential that is hidden in pharo. I recently saw a tweet from mr. Serge Stinckwich about how to build 2d buildings and rivers with the openstreetmap API and roassal as drawing support. I tried to replicate the code since I would like to play with it but I got some errors that I didn't menage to fix. So I was thinking to ask here if anyone has such code to share. Thanks in advance. Cheers, Nicolas

Re: [Pharo-users] Citizen example for manipulating a bibtex file

by Damien Cassou

from Damien Pollet: You will need to load the .bib file from zotero (read the file however you like, then pass the stream to the CZ parser). You'll get a CZBibSet (I don't recall the name exactly) which represents the contents of the file. A Set is composed of entries, each of which has a key and a set of fields. Finally, fields accept a few different kinds of values. Your processing is just iterating a set then setting the key of each entry (or possibly removing and re-adding the entry, I don't recall if it's implemented like a dictionary or more like a list).

Re: [Pharo-users] [squeak-dev] FFI syntax

by Annick Fron

Hi Eliot, Thank you. Meanwhile I have tried to use only pointers to structs by writing some C code. I confirm that in Pharo you can load FFI and OldAlien in the ConfigurationBrowser. Yet it seems both FFI and Alien versions in the ConfigurationBrowser are behind the squeak repositories. I did not try if the new versions worked. I have posted some time ago an example for X11 windows on Linux, and I never got an answer why it was failing. It was the following testGetOurWindowLocation "self new testGetOurWindowLocation" | display ourWindow aParent anX anY aWidth aHeight aBorderWidth aDepth | display := X11Display XOpenDisplay: nil. ourWindow := display ourWindow. (Alien lookup: 'XGetGeometry' inLibrary: 'X11') primFFICallResult: nil withArguments: {display. ourWindow xid. (aParent := Alien new: 4). (anX := Alien new: 4). (anY := Alien new: 4). (aWidth := Alien new: 4). (aHeight := Alien new: 4). (aBorderWidth := Alien new: 4). (aDepth := Alien new: 4)}. (anX unsignedLongAt: 1) inspect. Has anybody looked at Wayland (replacement of X11) on Linux ?

Re: [Pharo-users] FFI syntax

Works fine here with TightVNC. Worked all evening on a remote box that was quite far in FullHD. I noticed some missing keybindings (numeric pad for example). But that's because the supported mappings in RFB are incomplete, not because of bugs. Phil â

But only if it loads and works cleanly in that version of Pharo, we need a minimum of quality assurance.

I can push RFB in there as it seems to be missing.

Yes, for pharo this is easy. For squeak, it took me some time to get it "working" (at least the tests are green, examples do not work). 2014-10-16 8:49 GMT+02:00 Torsten Bergmann <astares(a)gmx.de>: > >I can not even find up to date information on how to *install* current > >working FFI > > In Pharo 3.0 open the world menu, then "Tools", then "Config browser" > and there look for "FFI" in the list ... > > If people would care on providing easy access to own packages > life would be easy for all. > > Bye > T. > >
