get output of a forked process on windows

by Christophe Demarey

Hi, I would like to evaluate a Smalltalk expression in a forked process (i.e. something like OSProcess thisOSProcess waitForCommandOutput: 'pharo Pharo.image eval "SystemVersion current dottedMajorMinor"'). It is doable on linux/mac with OSProcess but not on Windows. Is there another way to do that on Windows? I would prefer to avoid to write to a file. Thanks, Christophe

The user can write their own rules (for fundamentals, algorithms, quants, screening filters, etc). The code of these rules can be simple keys or Smalltalk blocks. When blocks, these are something like this: [ :aProcessorProxy | aProcessorProxy revenues / aProcessorProxy price ] and things like that. Basically, in general we pass by a "proxy" to a processor which then dynamically understands keys and ends up evaluating rules. Sure, we have problems with mathematical operators and their precedence etc. But we try to document this and provide many many examples. There is also a kind of debugger with some call stack about the called keys etc. See attached (all violet are links that open popups to see more info) And if you liked to see Smalltalk, did you see the rules browser? hahah. See attached. How large is the technical team that built / is building this ? It looks > like a really deep/wide application. > > The product started like a single-man project in 1996. It started with Python, then moved to Smalltalk. It has no UI back then. I joined them about 5 years ago and have been working for them since then. In these last years we started a new UI using Seaside and Bootstrap, start using Ajax everywhere, we started using GemStone for deploy, etc etc. The team was/is really small..... I cannot even believe myself how much we were able to do with the team size we had. And...I cannot stop thinking what we COULD do with a bigger team...
