Can anyone help me to work out why this is not working. Scanner: <anyLetter> : [A-Z a-z _ 0-9] ; <upperLetter>: [A-Z] ; <lowerLetter> : [a-z_0-9] ; Parser: Test : <upperLetter>+ <lowerLetter>+ <upperLetter> <anyLetter> ; Test String: HelloWorld I was expecting the parser to at least get past the 'o' in world. many thanks in advance Keith Send instant messages to your online friends http://uk.messenger.yahoo.com

SUnit missing tests.
by rvclayton＠acm.org 03 Jun '06

03 Jun '06

I have a project with the following categories and classes: ContextFreeGrammar ContextFreeGrammar ContextFreeGrammarTests GrammarProduction GrammarProductionTests EarleyParser EarleyParser EarleyParserTestCases EarleyParserTests ParseState ParseStateSet ParseStateSetTests ParseStateTests When I open a SUnit test runner, it lists the following: [blah blah blah] ColorTest CompiledMethodTest ComplexTest DateAndTimeEpochTest [blah blah blah] DurationTest EarleyParserTestCases EarleyParserTests EventManagerTest [blah blah blah] FractionTest HashAndEqualsTestCase [blah blah blah] OrderedCollectionTest ParseStateSetTests ParseStateTests PasteUpMorphTest [blah blah blah] That is, it's missing ContextFreeGrammarTests and GrammarProductionTests. How can I fix or get around this? I've tried various combinations of 1 switching between "Test" and "Tests", 2 filing out, deleting, and filing back in, and 3 closing and reopening the test runner with no success. This is squeak 3.8 update 6665 on a debian testing system.

Monticello Configurations help
by Ron Teitelbaum 02 Jun '06

02 Jun '06

Hi all, Ok, I got Monticello Configurations working. I have to admit I was thinking about ENVY configuration maps when I saw this and was hoping that Monticello Configurations would work much the same way. I loaded up the squeakSource image (thank you Cees for hosting the image and Torsten Bergmann for creating it http://de-1.tric.nl/~cg/images/ ) ported my code to 3.9a, stored all my changes. Then I created a test configuration and it worked. I was very happy. When I went to modify the configuration after doing an update, it did nothing. Storing did nothing. It didn't give any indication that it was going to do nothing. I think that the intention is for the user to provide a unique name for each configuration and when a name is reused it does nothing, so I provided a new name and that worked. Thinking ahead I could make this work by providing my own version numbering of the configuration, but looking around there doesn't seem to be a way to purge the old configurations from squeakSource. The configuration is not visible from squeakSource, and it appears to be hidden in data files, so deleting it manually seems problematic. Am I missing something? I would like to be able to version off configurations and purge old version when necessary, or I would like to be able to modify definitions. Is any of this possible? Is there another way to manage multiple packages load them all at once and save configurations of multiple packages? Also when defining a configuration and adding a repository it said that only http is supported. This was why I went looking for and setting up my own squeakSource. But when storing a configuration it asked me where to write it and it worked when writing to a directory. Assuming that the stored repository on the configuration is to be used as the source for loading a configuration, why doesn't the configuration support other repository types? Should I be storing versions of packages on squeakSource and configurations on a directory? Thanks for your help! Ron Teitelbaum

You can find it here: http://www.comtalk.net/Squeak/uploads/20/bootstrap7033.zip Simply take fresh Squeak 7033 image and load all the files. The resultant image has still some obsolete classes. You can browse mirrors using "MirrorsBrowser open". -- Pavel

[ANN] LispKit on SqueakMap
by Stéphane Rollandin 02 Jun '06

02 Jun '06

from the SqueakMap description: ------------- LispKit is a kit for building one's own custom Lisp implementations it's beta !! provides: 1) LispKernel, a minimal Lisp interpreter with - dynamic scoping - the fundamental special forms: let, setq, and, or, if, defun, defmacro ... - a few basic functions: list, car, funcall, null ... - catch/throw, unwind-protect - a GUI 2) SLisp, a Lisp dialect tightly integrated with Smalltalk usage: by subclassing LispKernel one can implement a custom dialect of Lisp. see SLisp for an example specificities LispKernel is implemented as a pure Smalltalk extension. There is no parser nor compiler; the interpreter is the 'eval' lisp function itself. Lisp code can be written as plain Smalltalk arrays. advantages: - we can chase the senders of a symbol - we can use the debugger to debug Lisp code - we can easily implement powerful control structures - we can integrate Lisp and Smalltalk ... see LispKernel class comments for more
