[9fans] geoloc - a crappy script I wrote.

[J.R. Mauro]

Hi,

Someone on contrib has a gmap (not the shell script one that was
mentioned recently, the older(?) one done in C). I made the following
stupid script to help start gmap at a user-specified address. Gmap
only understands coordinates, which I can't memorize. But it's
generally useful besides a gmap helper, I suppose. I'm trying to see
if I can get something like google maps directions based on geoloc
since the yahoo site it uses seems to not fail if you give it a very
vague address, unlike most other services I've tried. I suppose I
could try to see if I can get a barebones access to google maps
directions. Like an XML page or something. If anyone knows how, I'd
appreciate some pointers.

The script outputs lat and lon (in that order) delimited with a '?'
character, because that is what gmap uses. This is so that I can do
something like:

gmap -n`{geoloc 123 foo street anywhereville}

Please note that the gmap on sources expects longitude to come before
latitude for its -n option. I think that is backward from the normal
convention, so I modified mine locally to swap them. It's a simple
change.

The script is really stupid and calls sed 87 times because it's
parsing an ugly xml page and I don't know any better. Please feel free
to tell me how bad it is.

Without further ado:


#!/bin/rc
# geoloc - find coordinates of an address

if (~ $#* 0) {
	echo Usage: geoloc address
	exit
}

addr = `{echo $* | sed -e 's/ /+/g'}

hget http://api.local.yahoo.com/MapsService/V1/geocode?appid'='capelinks'&'location'='$addr'&'Geocode'='Geocode
| \
	awk -F'>' '{ print $4"X?"$6}' | sed -e 's/<.*eX//' | sed -e
's/<.*e//' | sed -e '/X/d'

steve's gmap script does a great job with arbitrary addresses.  for example

	; gmap 220 college ave athens ga

- erik

The gmap script is pretty cool, but I have problems with it on p9p and
it's not interactive. The other gmap has some nifty features I like.

I hope even if you don't use the other gmap you might like geoloc
since it is still useful in and of itself. Even though it's a hack.

Here's a hack on top of my hack. The real suckage comes from me making
geoloc separate lat and lon with '?' to appease gmap. It's a small
change if you don't like it. I really want subway directions, but
apparently Yahoo can't do that. I'll keep digging.


#!/bin/rc
# directions -- print directions from a coordinate pair to another.

if (! ~ $#* 2) {
	echo Usage: directions lat1?lon1 lat2?lon2
	exit
}

SLA = `{echo $1 | sed -e 's/\?.*//'}
SLO = `{echo $1 | sed -e 's/.*\?//'}
DLA = `{echo $2 | sed -e 's/\?.*//'}
DLO = `{echo $2 | sed -e 's/.*\?//'}

#echo I got: $SLA $SLO $DLA $DLO

hget 'http://maps.yahoo.com/print?mvt=m&tp=1&stx=&fcat=&frat=&clat='^$DLA^'&clon='^$DLO^'&mag=10&zoom=9&trf=0&radius=134.16445&&q1='$SLA'%20'^$SLO^'&q2='^$DLA^'%20'^$DLO^'&v3=0'
