RewriteTool matching parts of an array
by Peter UhnÃ¡k Aug. 11, 2016

Aug. 11, 2016

Hi, I wanted to use RewriteTool to rewrite dynamic arrays Source AST: | base | base := {#Department -> {710 @ 255. Color lightMagenta}} matching AST: | base | base := {#Department -> {``@first. ``@second}} transformation: | base | base := {#Department -> (Array with: ``@first with: ``@second)} However when I tried to execute it I was met with DNU OrderedCollection>>parent: It seems that the @first/@second part are not matched properly. Any way to fix this? Or am I doing it wrong? Thanks, Peter

manipulating strings
by stepharo Aug. 11, 2016

Aug. 11, 2016

Hi I have the following problem I want to transform a string into another while removing a set of characters 'Uquillas G\'{o}mez' -> 'uquillasgomez' And I wonder how to do that? copyWithoutAll: I was thinking to create a string of the same size and copy only the valid characters. Now I do not know how to set the size of the resulting string. I could use stream. Any ideas is welcome. Stef

Some interesting datasets | https://numeracy.co
by Sven Van Caekenberghe Aug. 10, 2016

Aug. 10, 2016

Hi, I know a lot of people are interested in (public) datasets (to use as examples). The website https://numeracy.co contains a (small) number of interesting ones. Here is how to access them using NeoCSV. (NeoCSVReader on: 'https://numeracy.co/standard-library/us-population/states.csv' asUrl retrieveContents readStream) upToEnd. or ZnClient new url: 'https://numeracy.co/standard-library/us-population/states.csv'; contentReader: [ :entity | (NeoCSVReader on: entity readStream) upToEnd ]; get. Of course, they don't use UTF-8 and don't advertise it, so on some datasets you need to do something extra. (NeoCSVReader on: (ZnDefaultCharacterEncoder value: ZnCharacterEncoder latin1 during: [ 'https://numeracy.co/standard-library/us-population/cities.csv' asUrl retrieveContents ]) readStream) upToEnd. (Warning: this last example is quite large, 500K records). Sven

Final CFP: DSLDI'16 at SPLASH
by Tijs van der Storm Aug. 9, 2016

Aug. 9, 2016

********************************************************************* FINAL CALL FOR TALK PROPOSALS DSLDI 2016 Fourth Workshop on Domain-Specific Language Design and Implementation October 31, 2016 Amsterdam, Netherlands Co-located with SPLASH http://2016.splashcon.org/track/dsldi2016 https://twitter.com/wsdsldi ********************************************************************* Deadline for talk proposals: August 15, 2016 (extended!) *** Workshop Goal *** Well-designed and implemented domain-specific languages (DSLs) can achieve both usability and performance benefits over general-purpose programming languages. By raising the level of abstraction and exploiting domain knowledge, DSLs can make programming more accessible, increase programmer productivity, and support domain-specific optimizations. The goal of the DSLDI workshop is to bring together researchers and practitioners interested in discussing how DSLs should be designed, implemented, supported by tools, and applied in realistic contexts. The focus of the workshop is on all aspects of this process, from soliciting domain knowledge from experts, through the design and implementation of the language, to evaluating whether and how a DSL is successful. More generally, we are interested in continuing to build a community that can drive forward the development of modern DSLs. An additional goal of this year's workshop is to encourage discussion about the usability of DSLs, and to establish connections with researchers in related areas, such as end-user software engineering, who have studied human factors of programming languages and tools. *** Workshop Format *** DSLDI is a single-day workshop and will consist of moderated audience discussions structured around a series of talks. The role of the talks is to facilitate interesting and substantive discussion. Therefore, we welcome and encourage talks that express strong opinions, describe open problems, propose new research directions, and report on early research in progress. Proposed talks should be on topics within DSLDI's area of interest, which include but are not limited to: * solicitation and representation of domain knowledge * DSL design principles and processes * DSL implementation techniques and language workbenches * domain-specific optimizations * human factors of DSLs * tool support for DSL users * community and educational support for DSL users * applications of DSLs to existing and emerging domains * studies of usability, performance, or other benefits of DSLs * experience reports of DSLs deployed in practice *** Call for Submissions *** We solicit talk proposals in the form of short abstracts (max. 2 pages). A good talk proposal describes an interesting position, open problem, demonstration, or early achievement. The submissions will be reviewed on relevance and clarity, and used to plan the mostly interactive sessions of the workshop day. Publication of accepted abstracts and slides on the website is voluntary. * Deadline for talk proposals: August 15, 2016 * Notification: September 5, 2016 * Workshop: October 31, 2016 * Submission website: https://dsldi16.hotcrp.com/ *** Workshop Organization *** Organizers: * Eric Walkingshaw (Oregon State University) * Tijs van der Storm (CWI) Program committee: * Iman Avazpour (Deakin University) * Christopher Bogart (Carnegie Mellon University) * Andy Gill (University of Kansas) * Sylvia Grewe (TU Darmstadt) * Kate Howland (University of Sussex) * Lindsey Kuper (Intel Labs) * Darya Kurilova (Carnegie Mellon University) * Ralf LÃ¤mmel (University of Koblenz-Landau) * Tanja Mayerhofer (Vienna University of Technology) * Marjan Mernik (University of Maribor) * Sarah Mount (King's College London) * Justin Pombrio (Brown University) * Tillmann Rendel (University of TÃ¼bingen) * Tiark Rompf (Purdue & Oracle Labs) * Sonja Schimmler (Bundeswehr University Munich) * Markus VÃ¶lter (itemis) * Peng Wu (Huawei America Lab)

How to wrap text in labels?
by Tommaso Dal Sasso Aug. 9, 2016

Aug. 9, 2016

Hello everybody, I was wondering, is there a way to wrap text inside a Morphic/Bloc label? I am building a list of text elements, but I am not able to wrap the text to match the width of the widget. For the moment I solved the issue by instantiating a Rubric text area for each text element, but it becomes much more resource expensive and slower. Is there a better widget to manage that? Thanks, Tommaso

generating function keys
by Peter Uhnak Aug. 8, 2016

Aug. 8, 2016

Hi, how can one generate function keys? (F1 to F12) I've made a morph for testing ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ c := Morph subclass: #MyKeyMorph. c compile: 'handlesKeyboard: evt ^ true'. c compile: 'handleKeystroke: evt self logCr: evt'. c compile: 'handleKeyUp: evt self logCr: evt'. c compile: 'handleKeyDown: evt self logCr: evt'. m := c new. m openInWindow. m takeKeyboardFocus ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ However the functions keys are not being generated. Is this something that would have to be done in the VM? I'm using linux btw, but ideally it should work on all platforms. Thanks, Peter

About magritte usage in pillar
by stepharo Aug. 7, 2016

Aug. 7, 2016

Hi cyril I would like to discuss with you about the use of magritte in pillar for configuration. In particular I do not understand why accessors are not simply generated and stored as part of the code. It will avoid to have defaultExporters: treated as an unknow message. activate super activate. self optionAt: 'to' ifPresent: [ :subconf | configuration defaultExporters: {subconf} ]. self optionAt: 'path' ifPresent: [ :path | configuration outputFile: (RelativePath from: path) ]. self parseInputFile. self export. self exitSuccess if you are on chat somewhere let me know.

Pillar question PRPrepareForGitBookCommandLineHandler
by stepharo Aug. 5, 2016

Aug. 5, 2016

Hi PRPrepareForGitBookCommandLineHandler defines the following method. PRPrepareForGitBookCommandLineHandler>>generateSummary (baseDirectory / 'SUMMARY.md') asFileReference writeStreamDo: [ :stream | stream << '# Summary' << String lf << String lf. stream << 'Abstract (to be done)' << String lf << String lf. self flag: #todo. "This cannot work anymore because inputFiles has been replaced by inputFile." configuration inputFiles do: [ :inputFile | | document title | document := configuration parseFile: inputFile. title := document title. stream << '* [' << title << ']('. (inputFile , PRMarkdownWriter fileExtension relativeTo: baseDirectory) printOn: stream delimiter: $/. stream << ')' << String lf ] ] and I do not get why configuration is sent parseFile: while only PRParsingPhase defines it.
