NAME¶
wmweather - dockable weather monitor
SYNOPSIS¶
wmweather
-s
<4-char ICAO location indicator> [
options]
DESCRIPTION¶
wmweather monitors local weather conditions: temperature, dew point,
pressure, humidity and wind direction and speed. The user needs to specify a
4-character `ICAO location indicator'. The standardized METAR station
designations and current weather reports are designed for use by the aviation
community. Since most major cities have at least one airport, there is usually
one or more METAR stations in a given city. You--obviously--need to be
connected to the internet and you also need to have libcurl installed.
wmweather will then attempt to download the latest METAR report for the
station of your choice from the National Weather Sevice run by NOAA.
You can toggle back and forth between imperial and metric units, i.e. between
degrees Fahrenheit, inches of Mercury, and miles per hour--and--degrees
Celsius, hectoPascal, and kilometers per hour. A middle click will do this.
Also, a left click will bring up the fully decoded METAR report in xmessage. And
a right click will force an immediate update, i.e.
wmweather will
attempt to grab weather information.
OPTIONS¶
- -s id, --station=id
- This option tells wmweather which METAR station to
show data for. id can be any four-letter ICAO location indicator,
which can be found at
http://www.nws.noaa.gov/tg/siteloc.shtml.
- -c, --compat
- Switch into compatibility mode. The old monitor style will
be used, default metric pressure units are millimeters of Mercury instead
of hectoPascal, and the colorization options are enabled. When the time
turns red, this means that the weather report is older than 24 hours. When
the wind speed turns red, this means that the wind is gusty and the listed
value is an average only. Similarly, a red direction indicates a variable
wind direction and the value given is the average direction. The symbolic
link wmWeather is functionally equivalent to
wmweather --compat.
- -d [@]min, --delay=[@]min
- Set the time (in minutes) between updates, default is 15
minutes. Use @ to specify minutes past the hour.
- -m, --metric
- Display metric values: temperatures in degrees Celsius
rather than degrees Fahrenheit, pressure in hectoPascal rather than inches
of Mercury, and wind speed in kilometers per hour rather than miles per
hour. This option can be toggled at runtime using a middle click.
- -w, --chill, -W
- Display wind chill--if available--instead of dew point
temperature.
- -e, --heat
- Display wind heat index--if available--instead of
temperature.
- -b, --beaufort
- Display wind speed on the `Beaufort scale'.
- -n, --knots
- Display wind speed in units of knots, i.e. sea miles per
hour.
- -u, --utc
- Display update time in UTC instead of localtime. This is
equivalent to --time=+0000.
- -t offset, --time=offset
- Convert update time according to (RFC 822 compliant) time
offset rather than to localtime, e.g. --time=+0100 for MET.
- -x host[:port], --proxy=host[:port]
- Proxy specification, this option is passed to libcurl.
- -U username[:password], --proxy-user=username[:password]
- Proxy authentication, this option is passed to libcurl.
Please don't specify this option, use the file ~/.netrc for
authentication instead.
- --lcd
- Use LCD style display.
- --display=id
- Set the display to use, e.g. --display=:0.0.
- --geometry=pos
- Set the position of the dock app. Note that the size
(64x64) is hard-coded and cannot be changed.
- -h, --help
- Display a list of command-line options.
- -v, --version
- Display the program version.
- -a, --hPa
- When toggled to metric, display pressure in units of
hectoPascals, i.e. milliBars.
- -k, --kPa
- When toggled to metric, display pressure in units of
kiloPascals.
- -g, --mmHg
- When toggled to metric, display pressure in units of
millimeters of Mercury.
- -p, --mps
- When toggled to metric, display wind speed in units of
meters per second.
- --bc=color
- When toggled to compatibility mode, set the background
color (#8e8e69 is LCD-ish).
- --lc=color
- When toggled to compatibility mode, set the color of the
labels, e.g. --lc=red or --lc=salmon or --lc=#4523ff.
- --dc=color
- When toggled to compatibility mode, set the color of the
data entries.
- --wgc=color
- When toggled to compatibility mode, set the
gusty-wind/variable-direction color. The wind speed indicator will turn
this color when the wind speed is gusty. The value shown in this case is
the average speed. Similarly, the wind direction indicator with change to
this color when the wind direction is variable. The value shown in this
case is the average direction.
- --tc=color
- When toggled to compatibility mode, set the color of the
ICAO location indicator and update time header.
FILES¶
- /etc/wmweather.conf
- The system-wide configuration file. Specify one long option
per line, e.g. station=EDDC or metric. Whitespace, empty
lines, and lines beginning with a # will be ignored.
- ~/.wmweather/config
- The user configuration file.
- ~/.wmweather/????
- These files contain the latest downloaded weather records
in decoded METAR format.
- ~/.netrc
- These file contains authentication information and should
be used in preference to --proxy-user.
ENVIRONMENT¶
- http_proxy
- The HTTP proxy to be used, see also --proxy.
