This library can be used to parse METAR coded weather reports and fetch current METAR reports from NOAA Internet Weather Service in Lua.
The parser is pretty simple and by no means claims to support every feature one might find in METAR coded weather reports. For example, weather forecasts and automatic weather reports are not detected. Unsupported features in the weather reports are silently dropped.
LuaSocket is
required for fetching weather reports from the Internet Weather Service.
On Debian/Ubuntu systems you can install the package liblua5.1-socket2
in order to get LuaSocket installed.
My Lua weather library is required for doing some unit conversions.
METAR parser home page is at
http://solitudo.net/software/lua/metar/ and it can be downloaded
by cloning the public Git repository at git://scm.solitudo.net/metar.git.
Gitweb interface is available at
http://scm.solitudo.net/gitweb/public/metar.git.
Install the src/metar.lua under some of the directories included in the
default LUA_PATH for your Lua distribution, or install under desired location
and set LUA_PATH accordingly. More info about LUA_PATH at
http://www.lua.org/pil/8.1.html.
API documentation for metar is available under the api/ directory of
the distribution.
