edist

Simple command line coordinate processing

SYNOPSIS

edist [option]... <command> <location...>

DESCRIPTION

edist operates on one, or more, locations specified in various formats. For example, a location string of “52.015;-0.221” would be interpreted as 52.015 degrees North by 0.221 degrees West, as would “52d0m54s N 000d13m15s W”. Positive values can be specified with a “+” prefix, but it isn’t required.

It is possible to use Maidenhead locators, such as “IO92” or “IO92va”, for users who are accustomed to working with them.

Users can maintain a local configuration file that lists locations with assigned names, and then use the names on the command line. This makes command lines much easier to read, and also makes reusing locations at a later date simpler. See CONFIGURATION FILE.

CONFIGURATION FILE

The configuration file, by default ~/.edist.conf`, is a simple ``INI format file, with sections headers defining the name of the location and their data defining the actual position. You can define locations by either their latitude and longitude, or with a Maidenhead locator string. Any options that aren’t handled will simply ignored. For example:

[Home]
latitude = 52.015
longitude = -0.221

[Cambridge]
latitude = 52.200
longitude = 0.183

[Pin]
locator = IO92

With the above configuration file one could find the distance from Home to Cambridge using edist -l Home -l Cambridge distance.

BUGS

None known.
