Parsers and their useful power
I have posted a new entry on the Ocean of Awareness blog: "Parsers and useful power". I look at what parser users want and what makes a parser successful, in light of the 1960s contest between the Irons parser, the first ever published, and recursive descent. One of those is very much with us today, and one survives only in the literature.
For more about Marpa, my own parsing project, there is the semi-official web site, maintained by Ron Savage. The official, but more limited, Marpa website is my personal one. Comments on this post can be made in Marpa's Google group, or on our IRC channel: #marpa at freenode.net.
I blog about Perl, with a focus on parsing and Marpa, my parsing algorithm based on Jay Earley's.
