So if I needed to parse data in C,
why did I not use lex?
It's pretty much standard on all Unix systems, right?
Yes,
but all it does is lexical analysis.
The job of parsing requires the use of yacc.
So why didn't I use yacc?
Beacuse it doesn't do lexical analysis.
If I use lex,
I also need to use yacc.
Why use two tools when one will suffice?
They are also both a pain to use,
so it's not like I immediately think to use them
(that, and the last time I used lex in anger was over twenty years ago …)
You have my permission to link freely to any entry here. Go
ahead, I won't bite. I promise.
The dates are the permanent links to that day's entries (or
entry, if there is only one entry). The titles are the permanent
links to that entry only. The format for the links are
simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are
interested in, say 2000/08/01,
so that would make the final URL:
https://boston.conman.org/2000/08/01
You can also specify the entire month by leaving off the day
portion. You can even select an arbitrary portion of time.
You may also note subtle shading of the links and that's
intentional: the “closer” the link is (relative to the
page) the “brighter” it appears. It's an experiment in
using color shading to denote the distance a link is from here. If
you don't notice it, don't worry; it's not all that
important.
