Re: [Pharo-users] How to grab a debug on Syntax Error?

Depends on whether you have a SyntaxErrorNotification or a SemanticError. For SyntaxErrorNotifications, you can wrap in a handler block raising a debugger (and will see at which index in source the error is for). Handling automatically is very kludgey without changes to the way OpalCompiler fetche

Re: [Pharo-users] Problem with input to XML Parser - 'Invalid UTF8 encoding'

XML expects a prolog in the document itself defining the encoding, if absent, the standard specifies utf-8. So when you use an XML parser to parse an HTML page, it will disregard any HTTP encodings, interpret the contents as an XML document with missing prolog, and try to parse as utf8. When you u

Re: [Pharo-users] Problem with input to XML Parser - 'Invalid UTF8 encoding'

In a class named XMLHTMLParser, you may expect that logic to be expanded a bit beyond the basic XML spec though. But since there are multiple potentially correct definitions, there will always be failure cases. Not to mention, in addition to XML/HTTP, HTML4/5 also define (different) meta tags for

A few easily fixed Type/pointers to Types mixups, and a slipup where two different classes are confused for the same aside, the real show stopper, if I haven't missed something entirely, is that the struct parser/NB in general does not handle const sized arrays*, which is used in a few of the requi
