Hi bill you can use FFI, we should write a chapter. I think that there are some material on the web you can define your own plugin. Have a look for the second on the chapter of the book http://stephane.ducasse.free.fr/FreeBooks/CollectiveNBlueBook/ On Apr 21, 2010, at 6:41 PM, Bill Rodgers wrote: > Hi Experts, > > How can I connect to libraries of the type that I would "include" in a C program?

How To Bind To External Libraries in Pharo ?

by Bill Rodgers

Hi Experts, How can I connect to libraries of the type that I would "include" in a C program? Must I re-compile Pharo to include them or is there some other way to do this at run-time? I'm looking at some Gnome libraries (GTK+, Gstreamer) which I would like to use from Pharo. Thanks, Bill

[CfP] DLS'10

by Pascal Costanza

Dynamic Languages Symposium 2010 October 18, 2010 Co-located with SPLASH (OOPSLA) 2010 In cooperation with ACM SIGPLAN John Ascuaga's Nugget, Reno/Tahoe, Nevada, USA http://www.dynamic-languages-symposium.org/dls-10/ ***** Call for papers ***** The 6th Dynamic Languages Symposium (DLS) at the conference formerly known as OOPSLA is a forum for discussion of dynamic languages, their implementation and application. While mature dynamic languages including Smalltalk, Lisp, Scheme, Self, Prolog, and APL continue to grow and inspire new converts, a new generation of dynamic scripting languages such as Python, Ruby, PHP, Tcl, and JavaScript are successful in a wide range of applications. DLS provides a place for researchers and practitioners to come together and share their knowledge, experience, and ideas for future research and development. DLS 2010 invites high quality papers reporting original research, innovative contributions or experience related to dynamic languages, their implementation and application. Accepted Papers will be published in the ACM Digital Library. Areas of interest include but are not limited to: * Innovative language features and implementation techniques * Development and platform support, tools * Interesting applications * Domain-oriented programming * Very late binding, dynamic composition, and runtime adaptation * Reflection and meta-programming * Software evolution * Language symbiosis and multi-paradigm languages * Dynamic optimization * Hardware support * Experience reports and case studies * Educational approaches and perspectives * Object-oriented, aspect-oriented, and context-oriented programming === Submissions and proceedings === We invite original contributions that neither have been published previously nor are under review by other refereed events or publications. Research papers should describe work that advances the current state of the art. Experience papers should be of broad interest and should describe insights gained from substantive practical applications. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Accepted papers will be published in the ACM Digital Library. Papers are to be submitted electronically at http://www.easychair.org/conferences?conf=dls2010 in PDF format. Submissions must not exceed 12 pages and need to use the ACM format, templates for which can be found at http://www.acm.org/sigs/pubs/proceed/template.html. === Important dates === Submission of papers: June 1, 2010 (hard deadline) Author notification: July 15, 2010 Final versions due: August 13, 2010 DLS 2010: October 18, 2010 SPLASH/OOPSLA 2010: October 17-21, 2010 === Program chair === William Clinger, Northeastern University, Boston, Massachusetts, USA === Program committee === Robby Findler (Northwestern University) Jeffrey S. Foster (University of Maryland) Lars Thomas Hansen (Adobe Systems) Charlotte Herzeel (University of Brussels) S. Alexander Spoon (Google) Eric Tanter (University of Chile) Jan Vitek (Purdue University) Alessandro Warth (Viewpoints Research Institute) [to be completed] -- Pascal Costanza, mailto:pc@p-cos.net, http://p-cos.net Vrije Universiteit Brussel Software Languages Lab Pleinlaan 2, B-1050 Brussel, Belgium
