From 1171ab38a505e56261842f09b942c06fe41e3561 Mon Sep 17 00:00:00 2001 From: Cesare Tirabassi Date: Tue, 7 Jul 2009 00:20:12 +0200 Subject: [PATCH] Added support for $weather (experimental). Download, parse and display METAR data from the NWS. icao must be a valid icao for the required location (see for instance https://pilotweb.nas.faa.gov/qryhtml/icao/). data_type must be one of the following: last_update : display the date (yyyy/mm/dd) and time (UTC) of the last update. temperature_C : display air temperature in degree Celsius. temperature_F : display air temperature in degree Fahrenheit. cloud_cover : display the highest cloud cover status. pressure : display air pressure in millibar. wind_speed : display wind speed in km/hour. wind_dir : display wind direction. wind_dir_DEG : display compass wind direction. humidity : display relative humidity in %. weather : display any relevant weather event (rain, snow, etc.). delay_in_minutes (optional, default 30) cannot be lower than 30 min. Up to 3 stations can be simultaneously queried. Use --enable-weather to compile this in. --- ChangeLog | 3 + configure.ac.in | 18 ++ doc/variables.xml | 25 ++ extras/nano/conky.nanorc | 2 +- extras/vim/syntax/conkyrc.vim | 2 +- src/Makefile.am | 6 + src/conky.c | 131 +++++++++ src/conky.h | 7 + src/text_object.h | 10 + src/weather.c | 497 ++++++++++++++++++++++++++++++++++ src/weather.h | 50 ++++ 11 files changed, 749 insertions(+), 2 deletions(-) create mode 100644 src/weather.c create mode 100644 src/weather.h diff --git a/ChangeLog b/ChangeLog index af00ce2d..55359af8 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,6 @@ +2009-07-06 + * Added support for $weather (experimental) + 2009-07-04 * Remove newline with comment only lines in TEXT * Improved parsing of graph arguments, removed "log"|"normal" arguments in diff --git a/configure.ac.in b/configure.ac.in index e0fd07c6..c2105ae2 100644 --- a/configure.ac.in +++ b/configure.ac.in @@ -343,6 +343,23 @@ if test x$want_rss = xyes; then AC_DEFINE(RSS, 1, [Define if you want rss support]) fi +dnl +dnl WEATHER +dnl + +AC_ARG_ENABLE([weather], + AC_HELP_STRING([--enable-weather], [enable if you want weather support @<:@default=no@:>@]), + [want_weather="$enableval"], [want_weather=no]) +# +AM_CONDITIONAL(BUILD_WEATHER, test x$want_weather = xyes) +if test x$want_weather = xyes; then + WANT_GLIB=yes + PKG_CHECK_MODULES([libcurl], libcurl) + CFLAGS="$CFLAGS $libcurl_CFLAGS" + LIBS="$LIBS $libcurl_LIBS" + AC_DEFINE(WEATHER, 1, [Define if you want weather support]) +fi + dnl dnl Lua dnl @@ -833,6 +850,7 @@ $PACKAGE $VERSION configured successfully: hddtemp: $want_hddtemp portmon: $want_portmon RSS: $want_rss + WEATHER: $want_weather Lua: $want_lua wireless: $want_wlan IBM: $want_ibm diff --git a/doc/variables.xml b/doc/variables.xml index 1f8d2e05..04d01e85 100644 --- a/doc/variables.xml +++ b/doc/variables.xml @@ -3198,6 +3198,31 @@ from 1.
