Re: new extension for pecl

Jesus, happy holidays and to you! On 27th I went to see what is this stuff SWIG (I mentioned this acronym in a weblog of Derick about Thies' thoughts in Paris). I read the manual page for wrapping libraries for PHP. It is not finished but as most software it is probably evolving. I will give it a try. However for now I am manually wrapping the library. There a few places where the code may be optimized(lowered by using common handler and just passing an pointer to the desired function). But you are right...this is very very big library that will cost me (and I hope in the future others will join) efforts to maintain. I try to implement all functions even those not applicable in the PHP enviroment. Unfortunately I don't know much about the Wez's streams API and thus functions that work with files are emtpy. Today I faced something weird for me. Instead of returning error codes the library just dies in case of error (and telling what was wrong). So the wrapper won't be very applicable in web enviroment. But with CLI this won't . Unfortunately this library is too mathematical for even with my background in physics for 5 years in the High School and Calculus in the university. There are decisions to be made whether to implement some part of the API by using resources or with more native primitives like hashes. So far the api for complex number calculations use to pass around objects of type CComplex. The sum/ passes around hashes and the histogram/ (will finish it in day or two) resources. Any comments are highly appreciated. Even I may give a link to the sources for those who wish to help in testing or in the developing. Best wishes, Andrey ----- Original Message ----- From: "Jesus M.
