Spent part of the weekend implementing a file buffer class and parser for yet another format (string, not binary). So I'm reading this email topic with a lot of interest.
It would be good to see some general interface/abstract for file/string reading and parsing. I just looked at the StringParser and other files briefly (would just note the lack of Unicode string parsing ;)) and they all bear similarities to a parser I spent some hours mocking a partial implementation of. There's a lot of re-useable code under the Zend/Pdf location that could be generalised, moved as suggested, and improved and I'd love to see that happen. I have a chunk of ideas that could use it! As it stands I have to give some though to using the current code (even if it's another non-PDF file, it's all plain text) in favour of what I might write - general or not it's better than reinventing something already in the framework. If nothing else it might help cut down development time even if I have to make minor changes via subclasses. ++1 to a proposal. :) Pádraic Brady http://blog.astrumfutura.com http://www.patternsforphp.com ----- Original Message ---- From: Matthew Ratzloff <[EMAIL PROTECTED]> To: Kevin McArthur <[EMAIL PROTECTED]> Cc: [email protected] Sent: Saturday, March 31, 2007 11:39:13 PM Subject: Re: [fw-general] Zend_File_Parser, Zend_String, etc. (was: Operating with file system: OO approach) On second thought, it makes more sense to have Zend_Parser_Interface Zend_Parser_DataSource_Interface* Neither with concrete classes (like SPL). Then Zend_File can implement Zend_Parser_DataSource_Interface and Zend_File_Parser can implement Zend_Parser_Interface. I'll look into this more thoroughly tonight. I can see all kinds of applications for it. -Matt * There's probably a better name for this.
