FOOP is the concept of functional object oriented programming in newLISP. It originated in a thread on the newLISP forum and was officially added to the interpreter for newLISP 9.3. Submit article

Version 9.3 of newLISP has been released and has new functions to facilitate working with XML. newLISP has had the ability to parse XML data into an association list since version 6.10. 9.3 adds the ability to more easily traverse a parsed document and edit its contents. Submit article

While the buzz is all about FOOP (functional object-oriented programming), I am more interested in some of the new functions supporting nested association lists. Submit article

Threaded applications are considered to be so difficult to implement properly that programmers are often encouraged to avoid them unless absolutely necessary. This is because of the difficulty in synchronizing data between threads. There are several techniques to accomplish this. Typical solutions involve sharing an area of memory or a pipe (a channel that maps [...]

In a previous entry, we used a simple C program and SWIG to extend Python. This was because iteration over Python’s strings, being more complex constructs than C’s character arrays, was not speedy enough for large strings. newLisp, being a high level, interpreted language like Python, also suffers from the same problem. However, newLisp’s unpack [...]
