[Pharo-project] learning rewrite rules

by Tudor Girba

Hi, I am trying to write a rewrite rule to replace something like: browser showOn: #xxx; from: #yyy; using: [ browser list ... browser tree ... ] to something like: browser transmit to: #xxx; from: #yyy; andShow: [:a | a list ... a tree ... ] I managed to do the following: RBParseTreeRewriter new replace: '`@browser showOn: `@target; from: `@origin; using: [ ``@.statements ]' with: '`@browser transmit to: `@target; from: `@origin; andShow: [:a | ``@.statements]'; yourself However, the problem here is that I do not know how to replace all the "browser" appearances with "a" inside the andShow: block. I tried multiple variations like the one below, but I could not seem to get it to work as I want. replace: '`@browser showOn: `@target; from: `@origin; using: [ `@browser ``@.statements]' with: '`@browser transmit to: `@target; from: `@origin; andShow: [:a | a ``@.statements]'; Can anyone point me into the right direction? Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

Re: [Pharo-project] Writing API for XML (WAX) - Bibliography example

by Hannes Hirzel

Thank you Stef, for pointing this out. I had a look at Torsten's email of July 6th about XMLWriter and the subsequent discussion. Yes, an alternative approach would be to model an XML generation API along the lines of Seaside html rendering -- with blocks instead of start/end messages. Has there some work going on elsewhere besides what Torsten did? http://squeaksource.com/PharoGoodies/XMLWriter-tbn.5.mcz --Hannes N.B. This is only about 'XML writing' NOT about XML parsing. The idea is to have an API which allows to have readable XML generation code with an implementation which does not consume much memory. And with enough examples and tests.

[Pharo-project] RoarVM: The Manycore SqueakVM

by Stefan Marr

Dear Smalltalk community: We are happy to announce, now officially, RoarVM: the first single-image manycore virtual machine for Smalltalk. The RoarVM supports the parallel execution of Smalltalk programs on x86 compatible multicore systems and Tilera TILE64-based manycore systems. It is tested with standard Squeak 4.1 closure-enabled images, and with a stripped down version of a MVC-based Squeak 3.7 image. Support for Pharo 1.2 is currently limited to 1 core, but we are working on it. A small teaser: 1 core 66286897 bytecodes/sec; 2910474 sends/sec 8 cores 470588235 bytecodes/sec; 19825677 sends/sec RoarVM is based on the work of David Ungar and Sam S. Adams at IBM Research. The port to x86 multicore systems was done by me. They open-sourced their VM, formerly know as Renaissance VM (RVM), under the Eclipse Public License [1]. Official announcement of the IBM source code release: http://soft.vub.ac.be/~smarr/rvm-open-source-release/ The source code of the RoarVM has been released as open source to enable the Smalltalk community to evaluate the ideas and possibly integrate them into existing systems. So, the RoarVM is meant to experiment with Smalltalk systems on multi- and manycore machines. The open source project, and downloads can also be found on GitHub: http://github.com/smarr/RoarVM http://github.com/smarr/RoarVM/downloads For more detailed information, please refer to the README file[3]. Instructions to compile the RoarVM on Linux and OS X can be found at [4]. Windows is currently not supported, however, there are good chances that it will work with cygwin or pthreads for win32, but that has not be verified in anyway. If you feel brave, please give it a shot and report back. If the community does not object, we would like to occupy the vm-dev(a)lists.squeakfoundation.org mailinglist for related discussions. So, if you run into any trouble while experimenting with the RoarVM, do not hesitate to report any problems and ask any questions. You can also follow us on Twitter @roarvm [5].

Re: [Pharo-project] Smalltalk Labs Browser

by Tudor Girba

Hi, I would also like to point out Glamour, an engine for building browsers. It is similar in intent with OmniBrowser in that it models the interaction independently from the rendering, but it aims to go further and model complex interactions. If you want to get an idea about it, here is a small tutorial example: http://www.themoosebook.org/book/internals/glamour/glimpse If you want to play with it, you can: - load it in a PharoDev 1.1: Gofer new squeaksource: 'Glamour'; package: 'ConfigurationOfGlamour'; load. (Smalltalk at: #ConfigurationOfGlamour) perform: #loadDefault - or get it from the nightly built Moose image: http://hudson.moosetechnology.org/job/moose-latest-dev/lastSuccessfulBuild/… Here is an example of a browser (in this case, only readonly) that is available on the web (best seen with Firefox). We use to browse the code meta-model we use in Moose: http://online.moosetechnology.org/moose/metaBrowser The same code can be seen by executing "MooseMetaBrowser open" in a Moose image.
