Re: [Pharo-users] Pharo /J - Integration

by Martin Saurer

Hi Alexandre Please have look at the video description on youtube. There you will find all the download links as well as instructions (ReadMe.txt) on how to install the Pharo (.mcz) and the J (pre-configured J environment) part. The .mcz file contains all the examples from the video. See www.jsoftware.com for more information, and tons of examples and essays about the J programing language. If you prefer videos for an intro to the language search for playlist "j in 10 minutes" on youtube. >From within Pharo, NativeBoost is used to access the jinter.dll/dylib/so (depending on your platform). Jinter then access the underlying J interpreter. Don't hesitate to ask me, if you have further questions. Martin > Hi Martin! > > I did not know J at all.

Re: [Pharo-users] Pharo / J - Integration

by Martin Saurer

Hi Stef Sorry, I didn't know the OOPAL paper until this evening :) I read through it very quickly, and I think it's a somewhat different approach I have to think about. To me the OOPAL concept looks like a smalltalk language extension, but with smalltalk oriented syntax, that is able to handle arrays in an easy and efficient way (without loops). The current Pharo/J integration is some sort of regular expression for math and array handling and manipulation from within Pharo. Personally I think the very compact (and sometimes cryptic) syntax of J is one of it's biggest advantages. It's not as easy to read and understand like smalltalk, but very efficient if you got some experience (like regex for strings). In my opinion, the OOPAL approach would be a set of smalltalk classes and methods which accesses an underlying array engine (like J). Please correct me, if I'm wrong. Currently, I'm unsure which approach is better. From a smalltalk point of view, the OOPAL approach is clearer. If you know both Pharo and J, it doesn't really matter. You can program all the enclosing stuff of a desktop- or web-application in Pharo, and just hack the number- crunching part (if there is one) in J. But again, I have to re-think about it ...

Dealing with multiple cases of a string while keeping code short and OOP friendly

by kilon alios

So I am parsing strings that represent python types and other custom objects. An example would be '<Vector (1.0 , 0.2 , 0.8) >' or '<Color (0.3 , 0.9 , 0.4 )>' etc But I dont want to use too many ifTrue , ifFalse and end up with a long method. So I was thinking creating a OrderedCollection that would be 2D , first dimension is the regex that fits the type the second is the pharo object that corresponds to this type . Then I will have a common method for each of those pharo object to deal with the parsing. But I was wondering how to use a class that I dont know its name until runtime. For example lets say i get a string aPythonString := '< Bone [ "side bone" , IK = True , ( 1.0 , 0.1 , 0.2) ]>' I would want in this case to send the message the EphBoneType parse : aPythonString. The problem is that I dont know the contents of the string until I receive it. So I want the name of the class to be composed according the string received . Is this possible ? Is this a smart way ? How would you do it ?

Better write something like: [[[render=false ... ]]] and fix pillar to ignore those blocks On Mar 8, 2015 3:55 PM, "Peter UhnÃ¡k" <i.uhnak(a)gmail.com> wrote: > Sure I can make a shortcut but I don't like that if there is already > something. > > So my question is why can't I do > > {{{comment: > > my > multiline > comment > > }}} > > We already have the syntax, and we already have conditional rendering; so > comment is just something that doesn't end up in any of the output formats. > > Peter >
