- Ed,

- All good stuff -- the world is coming together.
-
- What do you think is the most useful www option for tracing what's out there?
- I have two suggestions - one is a -list option (or something) which makes
- www return only list of related documents, one on each line.
- Another is one which will recursively run down a tree. The
- trouble with the latter is telling it where to stop. Depth isn't really good enough
- as probably you also want to constrain it to only gopher files, for example.
- Perhaps the most flexible would be just the first option, with a perl etc script
- around ir to be flexible. I'd link to see for example lists of all telnet sites
- references by gopher or www links, a wais server for www documents and gopher
- nodes. My guess is that one index could handle the lot so long as one trimmed
- off the few places where people have gatewayed in the entire ftp world, etc.
- Then I'd like to see a www server for that index so that one could jump straight to
- the docoument wherever it came from.... I have to write an articel today, maybe
- tomorrow I'll put in www -list.

- [PS: I assume you meant -p rather than -np in the www command. Perhaps we
- should put in -np if it is more intuitive than -p for no paging.
- I'll look at the CR problem.]

- Tim,

- Some more results of wais/www/gopher collaboration.
-
- I have a new WAIS server running at wais.cic.net, called
- "midwest-weather". It's fed by loading in a bunch of weather reports
- from a gopher at Minnesota every hour. That system gets them from the
- "weather underground" at Michigan using some hairy expect scripts, I
- figured it'd be easier to get things out of gopher instead.
-
- The script looks like:
-
- WEATHER=gopher://mermaid.micro.umn.edu:150/00/Weather
- www -n -np ${WEATHER}/Indiana/Fort%20Wayne | sed -e 's/.$//' > fort-wayne.in
- www -n -np ${WEATHER}/Indiana/Indianapolis | sed -e 's/.$//' > indianapolis.in
- www -n -np ${WEATHER}/Indiana/South%20Bend | sed -e 's/.$//' > south-bend.in
- [...]
-
- For some reason the gopher files are coming out of www with extra ^M's
- on the end, as if they were DOS files; so the sed thing gets rid of them.
-
- I don't see a way to do this with just one invocation of www, so
- instead it runs once for each file.
-
- Neither gopher nor WWW have the notion of a "recursive directory
- listing", either some complete overview of the structure of the system
- or some skeleton outline. (I realize it's arbitrarily hard to do so
- since any link could point off anywhere else.) That makes it tougher
- to do an archie-style catalog. I think it wouldn't be that hard to
- build a tree-walker for gopher that prints out a list of the
- directories on every system that it can find and also the text of all
- of the stuff that's in the ".about" directories. At the very least
- I'm doing some of that by hand now (just a script like the one above)
- & waising it so I have some clue what all is out there. *not* a
-
- replacement for the per-site indexes, but a cross-section.
