It would be relatively easy to translate str-utils to the CLR. It would make no sense to translate sql-utils (JDBC wrapper). I can't speak to all the nuances of Rich's thinking on the subject, but I'm pretty sure letting "each platform [do] its job" certainly applies to sql-utils. In other words, a library which is a wrapper around a Java library does not need to be on the CLR platform, and conversely. For str-utils, I think the question is more interesting. It will take a relatively small set of edits to make it run on the CLR implmentation, things like changing type hints, modifying method names -- .toLowerCase becomes .ToLower, for example. I've done this sort of thing to port core.clj, core_print.clj, etc. The manipulations are fairly straightforward. I have done them as manual edits. In fact, I have tried (successfully) to modify them without even disturbing the original line numbers, to ease moving changes over from the JVM version. For the core libraries, I think things need to remain this way. For other libraries, things in clojure-contrib such as str-utils, the question is whether there are a few coding techniques that, if followed, make it easy to write cross-platform code rather than doing ad-hoc manual editing. I would propose no changes to Clojure, no conditional compilation techniques or reader modifications. Just things like macros that have simple functionality and that at most check one flag to conditionalize output. Word of warning: even this level of bother may violate Rich's intent. In which case, I'll go away. I have a few ideas for this, but welcome design input from anyone with an interest. It's this, or write a a really nasty Perl script. :) -David --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
