This version of Learn Prolog Now! embeds SWI SH , SWI-Prolog for SHaring. The current version rewrites the Learn Prolog Now! HTML on the fly, recognising source code and example queries. It is not yet good at recognising the relations between source code fragments and queries. Also Learn Prolog Now! needs some updating to be more compatible with SWI-Prolog. All sources are on GitHub:

Chapter 6
More Lists

This chapter has two main goals:

  1. To define append/3 , a predicate for concatenating two lists, and illustrate what can be done with it.
  2. To discuss two ways of reversing a list: a naive method using append/3 , and a more efficient method using accumulators.
