[Pharo-project] Writing API for XML (WAX) - Bibliography example
by Hannes Hirzel Nov. 1, 2010

Nov. 1, 2010

Hello I read the post by Stephane Ducasse about writing XML (see below) with a bibliography example. Recently I (re)-discovered the port to Squeak/Pharo of the Writing API for XML (WAX) (http://java.ociweb.com/mark/programming/WAX.html) and could put it to good use for writing an XML file a bit more complex than the bibliography example. >From the web site WAX has the following characteristics: * focuses on writing XML, not reading it * requires less code than other approaches * uses less memory than other approaches (because it outputs XML as each method is called rather than storing it in a DOM-like structure and outputting it later) * writes all XML node types * always outputs well-formed XML or throws an exception unless running in "trust me" mode * knows how to associate DTDs, XML Schemas and XSLT stylesheets with the XML it outputs * is well-suited for writing XML request and response messages for REST-based and SOAP-based services However I do not know how far these points apply to the Squeak/Pharo port. http://www.squeaksource.com/WAX It needs the VB Regex package (http://www.squeaksource.com/Regex) As an exercise I did the code to produce the example Stephane gave. It worked fine; see below.

The biggest problem is that huge testsuites spend all their time searching the image for pragmas when printing the TestSuite.

Thanks nicolas. I prefer that than to chase a MC bug :) I wrote some tests too to cover the float printing and I will check yours.

Hi guys this morning I could not work on that issue when I integrated some pending changes. I could not run the tests to their completion. Actions: - we should look at that. - I would like to modularize tests Test-XXX -> XXX-Tests following the seaside patterns - subclass from longTest the tests taking time to run. Stef

Re: [Pharo-project] Syntax extension for continuations / class specific compiler

(I never discussed implementation and using continuations never occurred to me). My idea didn't seem popular then so I assume it won't fly now though, for the record, I would like to see such an operator. I prefer adding this syntax than the use of "asPipe" method (see http://blog.3plus4.org/2007/08/30/message-chains/) though I admit that asPipe is a very clever idea. I too dislike use of ";;" syntax; for me it conjures up the ugly "=" vs "==" syntax of C and subsequent languages that failed to fix this problem. ----------------------------------------------------------------------------------------------- One thing mentioned in the "asPipe" discussion is that each class can create it's own syntax/compiler. This strikes me as a really useful feature of Smalltalk. What I don't understand is: How do you do this? This feature is important enough that it should out in the open with proper documentation, some useful examples, etc. How about putting this information in Pharo by Example? If such a feature was available, and apparently it is, I would like to use it to be able write regular expressions or grammars as methods of a class and then have them be compiled from the editor (in the same way I do for smalltalk methods). Hopefully, I haven't upset too many by having two unrelated topics in a single post. Regards, Ralph Boland

[Pharo-project] XML package is barking at load time
by stephane ducasse Nov. 1, 2010

Nov. 1, 2010

Gofer new squeaksource: 'XMLSupport'; package: 'XML-Parser'; load. raise error because of tests not present. Did I do something wrong? Then why the configuration load pastell? why this is squeakCommon? Does it work if this is in pharo? Why do we load SIXX in gemstone? This configuration looks like a mess. Can somebody fix that. core should load the parser sixx may be sixx pastell should load core and pastell Stef version105: spec <version: '1.0.5' imports: #('1.0.5-baseline' )> spec for: #'common' do: [ spec blessing: #stable. spec author: 'Alexandre Bergel'. spec timestamp: '10/5/2010 14:06'. ]. spec for: #'squeakCommon' do: [ spec package: 'XML-Parser' with: 'XML-Parser-AlexandreBergel.93'; package: 'Pastell' with: 'Pastell-Alexandre_Bergel.18'.]. spec for: #'gemstone' do: [ spec project: 'Grease Core' with: '1.0-rc'. spec package: 'XML-Parser' with: 'XML-Parser.g-DaleHenrichs.93'; package: 'SIXX' with: 'SIXX-NorbertHartl.171'.].

Hi Hannes, I am not currently working on LightWidgets. If you're interested, Cuis includes a working implementation where you can use the UI pattern. Cheers, Juan Vuletich Ps. Please send copy to me of any mail intended for me... I'm not following the Pharo list closely, and I might miss it.
