FFI + Windows + Cygwin
by Mariano Martinez Peck 24 Jun '08

24 Jun '08

Hi everybody. I am developing SqueakDBX a openDBX C library. We are using FFI to call C functions. OpenDBX has always been compiled in linux and mac. But since the last version, it works under Windows using Cygwin or WinGW. I could test the library and works well (in windows). It has been generated the necessary .dlls. The problem is that theese .dlls files are in c:/cygwin/usr/lib/* . And, I can't "see" those functions from FFI. In FFI I am using apicall instead of cdecl (the one I use under linux). I have never work with C under linux. Can someone help me? thanks, Mariano

[ANN] new release of Prolog
by Stéphane Rollandin 23 Jun '08

23 Jun '08

hello list, the latest version of Prolog I just uploaded on SqueakMap features major changes (in my view improvements :) and is now seriously departing from the original Mike Teng code; it is backward compatible though. main points: * refactored the core code for clarity * fixed the semantics of or() and and() which are now exactly equivalent to the standard ; and , operators * defined three levels of database scoping: global, class-local and instance-local (global is still the default) * cached the mapping from prolog predicates (symbols) to their actual implementors (selectors) for faster evaluation * implemented an API for calling Prolog from Smalltalk directly, bypassing LParser/LCompiler. this is similar to the way LispKit interpreters handle code written in Array syntax and makes it possible to populate Prolog databases (which can now be class-local as stated above) with facts about live Smalltalk objects * enabled easy redirection of printed output (to Transcript or to an arbitrary WriteStream) * improved the GUI * added tests feedback, criticism, suggestions, etc. welcomed as usual Stef

Re: [squeak-dev] How to file out all the methods in a message list window?

The basic unit for creating fileouts is the change-set. So a way to approach this is to create a new change-set and get all the messages in your message-list to be in that change-set; then file-out the change-set. This will give you precisely what you want. But how to get all the methods that re in your message-list into the change-set? Here are four possibilities: (1) Select, in turn, each method in your message-list window; after each one is selected, type a space followed by a backspace (thus marking the method as "changed" without really changing it), then accept ("save") the method afresh. After you've done that to all methods in your method-list, the fresh change-set you created will bear precisely that method-list as its list of changes, so you can file out the change-set (using a change-sorter) and you'll have what you want. (2) Bring up, and "pin up', the shifted selector-list menu for the message-list in question. Find the item "add to current change set" there. Now, in turn, select each item in the message list, then hit that "add to current change-set" item. This places the method in the current change-set without actually modifying it. (3) If you have a big message list, both of the above may be too labor-intensive. So instead, you can open an Inspector on the model of the message list. In the bottom pane of that Inspector, type and then evaluate the following expression: self messageList do: [:mr | ChangeSet current adoptSelector: mr methodSymbol forClass: mr actualClass] (4) Finally, if you have a frequent need for such a feature, it would be a very simple matter to add a menu item to the selector-list menu to carry out the work described in alternative (3).

Mysql
by Bèrto ëd Sèra 20 Jun '08

20 Jun '08

Hello! I'm new to Squeak but I have spent several years programming in SmallTalk back then... so choosing squeak for a project would be a nice way to get my mostly good memories back :) The one and only problem I have is the same I used to have... object persistence :) I'm supposed to interface to a MySQL DB that accepts commands in XML (via a PARSER stored procedure) and answers with objects in XML format. It's VERY nice to see in the image that the XML library is there. This should make things pretty simple. Now... HOW do I connect to Mysql? Berto
