Re: [Pharo-dev] How often should a uninitializedvariable warning be shown?

by kilon alios

maybe pop up a dialog with the choice for the user to suppress any other warnings of same kind.

Re: [Pharo-dev] Parsing Pharo syntax to C/C++

Thanks Damien :) so I want to further explore Slang , that means downloading the VMMaker , I am following the post of Mariano here https://marianopeck.wordpress.com/tag/vmmaker/ and install VMMaker like this 1 2 3 4 5 6 Deprecation raiseWarning: false. Gofer new squeaksource:'MetacelloRepository'; package:'ConfigurationOfVMMaker'; load. ((Smalltalk at: #ConfigurationOfVMMaker) project version: '1.5') load. Question does CCodeGenerator contain the entire Slang ? I am downloading VMMaker to find how Slang plays with pointers and manual memory management so if you have any pointer (pun not intended) I will greatly appreciate it.

Re: [Pharo-dev] The Dilemma: Building a Futuristic GUI for Ephestos

by kilon alios

thanks for you kind words Ben. No the GUI I am developing for Ephestos is suppose to be separate from Blender , I have no intention of forking Blender and maintaining such fork. Regarding OSWindow that wont be necessary I will most likely use Ephestos to access pyQT which in turn will give me access to QT. So most likely I will be building the futuristic GUI on top of QT. I could also bypass python and do a C++ wrapper for pharo for QT, not full functionality but rather the parts that interest me but that will be a lot more tricky. I have changed my mind, with the advice I have been getting here and in the parser C++ thread it looks like I will keep using pharo for generation of my C code. Afterall Slang is already heavily used so I think I can rely on it. What Slang cannot do I can do it coding manually in C. So I think I can fit Pharo to my workflow quite a lot. Very happy to be proven once more wrong about Pharo :) On Mon, Sep 15, 2014 at 4:21 PM, Ben Coman <btc(a)openinworld.com> wrote: > kilon alios wrote: > > No offense intended but lately the more I dive inside Pharo the more I > feel I waste my time, I love the IDE and the environment and live coding > but using the libraries is a never ending struggle for me.
