Re: [Pharo-dev] [Pharo-users] managing keybindings with gtinspector

by Tudor Girba

Hi Ben, The prerequisite is the GTInspector which requires Glamour. Some of the extensions in GToolkit also rely on Roassal, but we will work in moving those in separate packages that should be loadable through a separate project.

Hi, I finally decided to update myself the Dr. Geo wikipedia page, although I don't really like doing so, as the author I may not have the appropriate neutral tone needed for wikipedia articles.

Re: [Pharo-dev] [ANN] Ephestos - Using and Coding Blender from inside Pharo

by kilon alios

Yeah !!! I did it !!! :D Apparently I was doing it wrong , by returning the message in doesNotUnderstand , this is why the next MNU was returned by Object instead of my parser class. Say bye bye to ugly nil syntax , Ephestos now supports normal pharo messaging. This ugly thing EphParser bpy:nil data:nil objects:'[ "Cube" ]' location: '=(0.0,0.0,0.0)' . has turned to this EphCParser bpy ; data ; objects:'["Cube"]' location:'=(0.0,0.0,0.0)' ; e. or this EphCParser bpy data objects:'["Cube"]' location:'=(0.0,0.0,0.0)'; e. or you can use parentheses . You can send all keywords as single message as I do in the example or separate them with parentheses to different messages , it does not matter because the parser unites them into a single string anyway. Message e, formulates the python string and marks the end of pharo command. Means that now I offer full python support with no weird pharo syntax :) New parser is called EphCParser if you want to give it a try, I am still working on it to make sure it works well in all scenarios. this is an example of using python globals for making the code shorter EphCParser x:'=1.0' ; e. EphCParser cube:'=bpy.data.objects["Cube"]';e. EphCParser cube ; location:'=(x,0.0,0.0)' ; e. You may wonder , "why not use pharo variables instead ?" . Well you can do that too ;) cube := EphCParser bpy data objects:'["Cube"]'. cube location:'=(x,0.0,0.0)' ; e. I will try to test the new parser a bit more and I will work on 1) receiving data from Blender 2) python errors triggering the pharo debugger and 3) buffer together multiple lines of python code for complex stuff like class and function definition etc 4) support BGE .

It's currently using FFI because that's what existed at the time of writing. But it would be interesting to rewrite the foreign call with NativeNoost. The bad news is that there are a lot of entry points! The good news is that most of the foreign calls were generated, so a slight adaptation of the generator for using NativeBoost instead of FFI should do the trick... Or we can attempt an automatic translation FFI->NativeBoost (the range types used in LAPACK is quite limited, so it seems feasible). Does it exist? The second point is that some LAPACK functions take more than 15 parameters, so a Compiler hack is necessary to transform these calls into a single parameter array at the Smalltalk level. The hack exists but is written for the Old Compiler. No problem in Pharo 3.0. For Pharo 4.0, it's possible to port the same principle to the New Compiler, but at first glance it's far less simple (many more classes to modify/derivate). Or in the interim, make the Old Compiler a separate package and declare a dependency on the Old Compiler...
