Hi,
Does anybody know what would be the *best* way to slice and dice the
documentation source files to produce "nuggets" per predicate?
As far as I can see, the gprolog runtime doesn't have apropos or help
predicates like some other implementations so I have decided that as an aid
to learning more I am going to try to implement them but of course they
need access to the underlying documentation for the meat of the output.
I can see from the source distribution that the documentation is written
using .tex files (I have used LaTeX for many many years) BUT would it be
*easier* to pick apart the large single HTML file instead. The H4 tags
carry the predicate name which is useful as a starting point.
I would like to have something like this:
help(predicate).
Dump the relevant part of the help file to the console.
I have written a "C" extension that wraps the dynamic link library calls
(dlopen,dlcose etc) and so far that seems to show promise. I was toying
with writing the actual implementation in C using libxml or something to
scour the HTML file, on demand. My other approach would be to produce a
"database" (bunch of files called predicatename.txt) and then just
interpolate the filename from the help argument and do it that way.
Whatever, with all programs it comes down to defining the data first!
I really like GNU Prolog, I started with SWIPL but it's too big
a dung-ball for me right now. Ciao seems "ok" but again, too big
a dung-ball. I like the lean and mean approach with GNU Prolog plus the
opportunity to make it better with my own extensions.
Thanks,
Sean Charles.
