Regarding the autocomplete project information

by Siddharth Gupta

Hello, I am interested in taking up the autoComplete project. I played around Pharo last year too. Could you tell me places to start from, with respect to the autocomplete project.

Torsten Olivier in our team that is perl freaks from time to time, told me that this is sad that Pharo regexp are not compatible with the "standard" = rePlugin. And I think that his remark makes sense. I was wondering if we should not ressurect the RePlugin to make sure that users can use perlish regexp and do not feel that our world is strange. Do you have experience with re in the past? What do you think about this proposal? Stef > Hi, > > I wrote a little tool to test regular expressions and verify that > given samples match it.

Re: [Pharo-dev] [ANN] XML Metadata Interchange (XMI) for Pharo

Hi torsten do you know the work of peter to generate classes out of XMI and populate models? Because it complements your approach. stef On Wed, 01 Mar 2017 22:26:05 +0100, Torsten Bergmann <astares(a)gmx.de> wrote: > Hi, > if you work with UML, modeling tools or model data exchange often you > might know XMI - > the XML Metadata Interchange format. > I wrote a little package that makes it easier to work and browse data > based on this > format within Pharo. > For instance you can open an XMI object either from a given stream > or URL: > (XMIFile fromURL: 'http://www.omg.org/spec/UML/20131001/UML.xmi') > inspect > You can also open a file > XMIFile importFile > Code is available on https://github.com/astares/Pharo-XMI > The package includes a small GT extension allowing you to walk and dive > through the XMI > structure (see attached screenshot) and as the XMI nodes are unified it > is easy to > code some code generators or transformers in Pharo afterwards. > For instance I used this package for a simple Pharo code generator based > on Eclipse EMF models/diagrams. > Within the code you will find some examples to browse through prominent > XMI models like: > - UML Spec > => (XMIFile fromURL: 'http://www.omg.org/spec/UML/20131001/UML.xmi') > inspect > - VISUAL PARADIGM > => (XMIFile fromURL: > 'https://raw.githubusercontent.com/staruml/XMI/master/unittest-files/VP_XMI2…') > inspect > - ENTERPRISE ARCHITECT > => (XMIFile fromURL: > 'https://raw.githubusercontent.com/staruml/XMI/master/unittest-files/EA_XMI2…') > inspect > - ARCHIMATE > => (XMIFile fromURL: > 'https://www.reflektis.com/repos/archimate-3.0.xmi) inspect > Once the inspector opens you have to select the "rootNode" and then the > "Hierarchy" tab. > In Pharo 6 you can load "XMI" right from catalog.

[ANN] XML Metadata Interchange (XMI) for Pharo

by Torsten Bergmann

Hi, if you work with UML, modeling tools or model data exchange often you might know XMI - the XML Metadata Interchange format. I wrote a little package that makes it easier to work and browse data based on this format within Pharo. For instance you can open an XMI object either from a given stream or URL: (XMIFile fromURL: 'http://www.omg.org/spec/UML/20131001/UML.xmi') inspect You can also open a file XMIFile importFile Code is available on https://github.com/astares/Pharo-XMI The package includes a small GT extension allowing you to walk and dive through the XMI structure (see attached screenshot) and as the XMI nodes are unified it is easy to code some code generators or transformers in Pharo afterwards. For instance I used this package for a simple Pharo code generator based on Eclipse EMF models/diagrams. Within the code you will find some examples to browse through prominent XMI models like: - UML Spec => (XMIFile fromURL: 'http://www.omg.org/spec/UML/20131001/UML.xmi') inspect - VISUAL PARADIGM => (XMIFile fromURL: 'https://raw.githubusercontent.com/staruml/XMI/master/unittest-files/VP_XMI2…') inspect - ENTERPRISE ARCHITECT => (XMIFile fromURL: 'https://raw.githubusercontent.com/staruml/XMI/master/unittest-files/EA_XMI2…') inspect - ARCHIMATE => (XMIFile fromURL: 'https://www.reflektis.com/repos/archimate-3.0.xmi) inspect Once the inspector opens you have to select the "rootNode" and then the "Hierarchy" tab. In Pharo 6 you can load "XMI" right from catalog. Hope the package is useful for others too. Bye T.

[ANN] Regex Tester Tool for Pharo

by Torsten Bergmann

Hi, I wrote a little tool to test regular expressions and verify that given samples match it. It also helps to divide an expression into subexpressions to retrieve parts of a matched string. Screenshot is attached. Code, load instructions and full tutorial on how to use it is on https://github.com/astares/Pharo-Regex-Tools Hope it is useful for others too. Have fun! Bye T.

Re: [Pharo-dev] [squeak-dev] Re: [vwnc] Does anyone have a "new" string literal?

by DavidLeibs

Let me add some more motivation and background for the discussion. I responded to stepharong(a)free.fr questions by mail yesterday but it didn't wind up on the forum. Sorry about that. http://www.erights.org/elang/quasi/overview.html Provides very good background for quasi-liberals. I believe this work lead to the ES6 solution by way of Mark Miller. As to macros I would posit that you have been using them in Smalltalk80 all along without the benefit of having the capability for yourself. There are a classic set of selectors that get special processing by the compiler. "to: do:" is an example of one. It gets turned into a while loop by AST transformation. These special selectors that are really macros are known to the compiler in a special table. A proper macro system opens the capability up everyone. As to 30 years without noticing that macros were needed, I would say they are long over due. I needed them back in 1997 when Adele Goldberg and I had a company called Neometron. We used them for for a large system that had thousands of templates in a template language which had escapes Smalltalk80 code embedded within. Also embedded within the tempting code and Smalltalk code was SQL code. This was allowed to be recursive so it was a little language free for all. We did not want string concatenation style coding with errors only found at run time. By having a Smalltalk80 with macros and quasi-literal little languages we and our non programmer users continued to compile method by method in the browser as usual but all the errors in template or sql syntax were found at compile time. There were no external files and everything continued to work with Change Sets and Change List technology that allowed recovering after a crash. The compile time processing by way of compiler staging plugins also allowed for an order of magnitude performance increase because there was a lot of evaluations that could be done in advance. By doing the work properly in the parser and compiler and making sure code transformations tracked source code offsets proper single stepping in the debugger was preserved. Of course if really aggressive rewriting was done you would sometimes have to debug in the expansion but we emitted code to help the debugger with macros and custom optimizations. The need to debug some macros in the expansion is a very old unsolved problem. Sadly, I was unable to convince Eliot and Steve Dahl to incorporate the work into Visualworks 20 years ago. Also sadly, I don't spend a lot of effort arguing with people that don't understand the need for some technology I see as useful. I have continually had to wait years before the time was right. :-) I know this will sound a bit "Snarky" but for more examples I suggest taking a look at 60 years of Lisp. Stochastic sampeling of the corpus should be revealing. :-) And now for a appeal to authority, "Lisp isn't a language, it's a building material." - Alan Kay and in conclusion: Simple quasi-literally are relatively easy and can be done with out being too disruptive. A real macro system takes very careful design that leads to compiler plugins that can go way beyond macros and open up a world compile time meta programming and the wonderful world of application dependent optimizations. cheers, -David (voice from the distant past) Leibs -- View this message in context: http://forum.world.st/Re-vwnc-Does-anyone-have-a-new-string-literal-tp46670… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
