[REBOL] Re: Parse refactoring puzzle

From: SunandaDH:aol at: 1-Aug-2003 11:44

Hi Joel:

Absolutely, -- and I am also cutting corners by producing a function that does just what I need rather than a generic industrial-strength one. For example, an industrial-strength clear-place-holders may need options to: ** only clear officially-sanctioned place-holders ** do "automatic" replacements for place-holders like !!date!! or !!user-name!! ** report stray place-holders left over (because, for some applications, that would indicate a serious error) ** behave differently depending on whether it is running test or production (e.g. test pops up a message, production silently writes to an error log)

That's a useful approach that doesn't really fit my case. For example, one of my place-holders is: !!dynamic-field!! That gets replaced by a HTML table row with an input field _and_ another !!dynamic-field!! place-holder. So the application uses this place-holder as it trundles through the database to dynamically create input fields. At the end, clear-place-holders, removes the !!dynamic-field!! place-holder. That's more of a dynamic structure than might be easy with a fixed table at the start. Hi Maxim:

I think if I was starting again, I'd definitely look at Steel or REBOL Server Pages for HTML webpage creation. As it is, I've got a half-built set of tools and a load of HTML templates using the !!xx!! schema, and I'm stuck with that until I bite the bullet and refactor. Thanks both for the ideas and encouragement! Sunanda.
