I ported it to VisualAge, maybe we should exchange notes. I am still not happy with the result, for the previous version I had optimized it to use a VA-specific primitive (Character>>testBit: - very useful little primitive, the VA scanner also uses it (I suspect they implemented it specifically for that)) instead of is... methods, and I did not get to do it yet for the current version. This is actually not just an optimization, I consider it a bug-fix as well - one cannot rely on every method in Character that happens to start with "is" to be fast. Plus you don't know in which environment you are using SmaCC and what kind of extensions people have implemented there. I know that I hit some really bad such methods (now I don't remember if it was ours or some third-party extension). Plus, you are generating a parser that relies on methods that may not be there at runtime. Anyway, I also have some ideas for what I think would be some improvements for SmaCC. Too many ideas, too little time (: Florin

Darn, I think we must have both done our updates on the same day. The last update I did was this (time stamp is GMT -4 hours) : CommandShell-dtl.76 Dave Lewis, 5 October 2014 5:29:32 pm CommandShell 4.6.9 Improve pipe closing for PipeableOSProcess class>>command: and related methods to support use as stand alone command processor. An expression such as the following will now close all open handles when command processing is complete: "(PipeableOSProcess command: '/bin/echo this is a test') output" If you could update the configuration to pick this up, that would be great. I think it will be helpful for people who want to easily execute commands directly from the image. I think the two sub-packages that you would update are CommandShell-Base-dtl.38 and CommandShell-Piping-dtl.16 Thanks, Dave > Hi Dave, > > thanks to you.

Hi Dave, thanks to you. I updated OSProcess to 4.5.11 and CommandShell to 4.6.8; are those the latest? I did it last Sunday. Thierry Le 09/10/2014 22:42, David T.

I have tried to embed that kind of philosophy in the previous to last programming language I helped design and implement, but didn't manage to setup the right PhD subject and candidate to integrate that into the IDE/Compiler. I approached a visualisation 'guru' who was very interested, but we didn't manage to get the subject / project of the ground.

Please explore when you'll have time, and describe what you end up with. I have the feeling that Pharo is moving towards providing building blocks to reuse as foundations for that kind of work: Roassal, parsers, ASTs, traces, code models, etc... so that we may build any needed visualisation, as Moose is using for software in the large. I'm currently on a medium to long term quest to learn in depth / maybe improve the AST automatic generation in SmaCC; it should give me a core foundation (a common API for the ASTs for all langages that SmaCC can parse) to build upon interactive visualisations IDEs for the programming languages I'm getting involved in: yesterday C, now R, tomorrow (I hope) Fortran and Python. But this is more about static analysis than runtime behavior analysis, unless I turn to VectorFabrics underlying tech... Hum, this one is ... interesting. It opens new ideas. Thanks a lot, this is really great! Thierry

Hi Noury, OSProcess is alive and well. Let me know if you have any problems with it. The Metacello configurations might be due for an update for Pharo, as there is at least one recent update that would be of interest to users of PipeableOSProcess (in www.squeaksource.com/CommandShell) Dave

Hi Noury, no, OSProcess on Squeaksource is not dead and is integrating all the changes needed for all the platforms it is running on. And as you can see, I very recently updated the configuration to make sure it was pointing to the very latest version.

Hi, Just tried to install the stable version of OSProcess using the configuration browser on a 3.0. I noticed it is still on http://www.squeaksource.com/OSProcess. Does it mean it is dead? if yes, what is the alternative? Thanx Noury
