The Debian Project                                 March 2024                                       WMWEATHER(1)

       Please report any bugs to <martin@godisch.de>. Debian users are encouraged to use the Debian Bug Tracking
       System at http://bugs.debian.org/wmweather.

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.

http_proxy
              The HTTP proxy to be used, see also --proxy.

/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.

-sid,--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 https://www.notams.faa.gov/common/icao/.

       -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.

       -i,--imperial
              Display  imperial values: temperatures in degrees Fahrenheit rather than degrees Celsius, pressure
              in inches of Mercury rather than hectoPascal, and  wind  speed  in  miles  per  hour  rather  than
              kilometers 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.

       -toffset,--time=offset
              Convert  update  time  according to (RFC 822 compliant) time offset rather than to localtime, e.g.
              --time=+0100 for MET.

       -xhost[:port],--proxy=host[:port]
              Proxy specification, this option is passed to libcurl.

       -Uusername[: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.
