PetitParser in 3.0?

by Martin McClure

Anyone using PetitParser in Pharo 3.0? What's the best repository to find PP for 3.0 in? Thanks, -Martin

In Dale's story, the "critical code had not only been moved to a different class but the critical method had been moved to a separate package" -- MC doesn't have anything to track "multipackage commits"; (I don't think it needs it, even though it proved useful in Dale's example, because when we have a set of packages we care to work together, MC can instantiate a MCConfiguration to define it). The reason you were able to see the history of WeakRegistry today even though it had been moved from Collections to System is that the MCDefinitions instances are indexed simply by their #description, which is package agnostic. It didn't care that it moved packages. > MCHttpRepository > location: 'http://box4.squeak.org:8888/trunk' > user: 'squeak' > password: 'squeak' > > to the Monticello Browser and then add it to the packages one is > interested in (a script to add it to all is trivial), then a "Browse mc > history" menu item becomes available on the class and method lists in the > browser and voila, one can browse the entire class and/or method history. > > This feature has been missing for a long time.

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

by kilon alios

Does it work with Pharo ? I downloaded the documentation and is really well written. But I have no clue how to test with Pharo. Communication of languages and apps through sockets is nothing original or rare. I was actually considering expanding Atlas to not only talk to python but also talk to Pharo as well. My goal is to make pharo take advantage of multi core cpus. Each new instance of Pharo takes on core because this is how OS works with processes and Atlas could act as a net of communication between different instances of Pharo. Possible its an idea I wont work on but its something I consider in the back of my head. But if its easy enough I may do it.

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

by kilon alios

I do have some great news I solved the problem with blender operators that means I now have full access to the whole API of blender. Everything in Blender API is basically operators and properties.There are still limitations to be solved of course. First that I will tackle is how to communicate data from Blender back to Pharo. Also I have added example code for people to look at. Just pull from my repo here http://www.smalltalkhub.com/#!/~kilon/Ephestos/ Ephestos is not something I am making for others to use, its primarily for my needs. Because I am very interested in interacting and integrating other Blender addons in my workflow I want to keep the Pharo API as close to BPY as possible. This will make it easy for me to port BPY code to pharo and talk to existing Blender addons. Blender addons are extremely important they implement tons of new functionality for Blender. A cube is not a separate object in BPY , a cube is basically a mesh object. So BPYMesh would make more sense. But in BPY its really a BPYObject. Additional I can be lazy and avoid documenting stuff since translating python calls to pharo is dead easy. Python has a very simple syntax, not as simple as Pharo but quite close. So its easy to go to Blender wiki BPY API and find all the information you want instead of me going through the pain of rewriting this huge documentation. There are also a lot of tutorials about making blender addons with python online, there is no way I can compete with that . So in the end if you really want to take advantage of Blender learning python and the blender api is mandatory. Pretty much every major 3d app uses Python and Python is a very popular language so there is nothing to lose by learning it. I would not put too much faith to me mapping alone the huge BPY API, the operators alone are 1500 or so I have been told, properties must be at least double that amount. Translating all that to Pharo objects is just an insane amount of work unless I find a cleaver way around it with some pharo parsing but still too much work for little gain. But I will map some basic stuff to decrease the need of writing python code. About Atlas here is the repo that I am going to post the code https://github.com/kilon/pyAtlas For now I work on Ephestos and when I am happy with the progress I made with it I will port it to Atlas and make an announcement here. Its basically the same code minus the Blender stuff. PS: It may also make some of you happy that I plan to expand Ephestos to include besides BPY also BGE. BGE stand for Blender Game Engine , its a game engine offered by Blender that excels at any kind of interacting graphics, that means that you will have access to a very powerful game engine and a general engine for 3d interactive applications. BGE is a lower priority , but it should be easy to implement once the big limitations of Ephestos have been solved. More info about BGE can be found here http://wiki.blender.org/index.php/Doc:2.6/Manual you can find finished games made with BGE here http://blenderartists.org/forum/forumdisplay.php?39-Finished-Games A very good example is this http://deadcyborg.com/ On Thu, Jul 17, 2014 at 8:31 PM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > > 2014-07-16 12:31 GMT-03:00 kilon alios <kilon.alios(a)gmail.com>: > > yes the one I am considering as strong candidate is >> >> (BPYObjects at: 'Cube' ) location : #( 0 0 0 ) >> >> > Why not BPYCube? > > > >> I would try to simplify bpy ( Blender Python API) and make it a lot more >> pharo friendly. >> >> However plain python string will be kept as well, so you can copy paste >> existing python code. >> >> One thing to note here is that Blender python addons are a huge deal. >> Python addons are actually full blown python apps.

exact differences between two bits of JSON

by Paul DeBruicker

Hi - Is there a convenient way to get only the differences between two json strings (or JSONObjects, or Dictionaries)? Say I have JSON objects (or dictionaries constructed from JSON strings): A { "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } and B { "glossary": { "title": "example glossary", "GlossDiv": { "title": "XXXXXXX", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "XXXXXXX", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } (assuming they aren't pretty printed and aren't in the same key-value order when created) Is there a method in Pharo that will pull out the key-value pair with the "XXXXXXX" values in piece B if I compare it with piece A?
