WundergroundPlugin

Provides weather forecast for a specified place, using the Weather Underground service.

Syntax Rules

%WEATHER{"5-digit-zip" options...}%

%WEATHER{"City, State" options...}%

%WEATHER{"City, Country" options...}%

%WEATHER{"AirportCode" options...}%

%WEATHER{"lat,long" options...}%

%WEATHER{"IP:address" options...}%

%WEATHER{ options...}%

Expands to the weather forecast obtained from Weather Underground's weather API for the specified place as a table. Additional information can be obtained by hovering over the table cells. Hyperlinks to the full forecast and to the terms-of-service page are included. Note that because some data is displayed conditionally, the table size may vary.

The default location is the IP address of the Wiki client. IP geolocation is imprecise, and so shouldn't be relied upon. It definitely won't work for private IP addresses.

lat,long are in decimal degrees.

The Weather Underground servers are queried at most every 15 minutes for the same data to reduce the chance of exceeding the license quota. Cached data is served between queries.

Options

Options are specified in the usual format -- each option is of the form name="value", where the quotes are required. multiple options are separated by spaces.

language

Specifies the language of the forecast. Default is "en". Note that the tags are not the ISO country or language codes.
See the Weather Underground documentation for the list of supported languages and tags.

heading

Specifies whether or not to include the place name and forecast time before the table. Default is true.

tableattributes

Specifies a string to be passed to the %TABLE% directive of the TablePlugin. May be used to customize the formatting of the table. Note that double quotes must be escaped with a backslash.

units

Specifies the units for measurements: ' metric ' uses SI units (°C, km/H, etc); ' us ' uses English units (°F, mi/H, etc). The default is us.

future

Specifies how many days beyond current conditions to forecast. 0 means the rest of today. 1 will include tomorrow. The maximum value is 4 (a Weather underground limit).

nocache

If set to a true value, the cache will be ignored. Use only if your license is unlimited and you want up-to-the-second data. This is rarely wise.

Issues

  • At this writing, the Weather Underground geolocator does not support IPv6 addresses.
  • Strings initiated by the plugin do not follow the language codes. They can be replaced using %MAKETEXT%
  • Weather Underground uses observations from its own network of stations. These may (or may not) agree with official observing stations.
  • Links to the Weather Underground website in this document may have changed by the time you read this.
  • %WEATHER% can not be embedded in a TML table (work-around is to embed in an HTML table).

Examples

%WEATHER{"85003"}%

%WEATHER{"85003"}%

%WEATHER{"London, England" tableattributes="tableframe=\"border\"" future="0"}%

%WEATHER{"London, England" tableattributes="tableframe=\"border\"" future="0"}%

%WEATHER{"CDG" language="fr" units="metric" tableattributes="databg=\"none\"" heading="1" future="3"}%

%WEATHER{"CDG" language="fr" units="metric" tableattributes="databg=\"none\"" heading="1" future="3"}%

The plugin is not enabled on this system. Here is a screenshot showing the expansion of the examples. It does not exactly match the latest version of plugin. Of course the links and hover text are not active in this screenshot.
Examples.

Plugin Settings

There are no user settings for this plugin.

The API key is stored in {Plugins}{WundergroundPlugin}{ApiKey}, found in the Extensions section of the configure script. This can only be done by the wiki administrator.

Plugin release notes

This replaces the obsolete GoogleWeatherPlugin. It provides better data and some additional location options.

It also provides more detailed data than GoogleWeatherPlugin did - hovering over most elements is worthwhile.

It should service the %WEATHER% macros in existing topics, although the resulting table size and contents vary.

Some options from GoogleWeatherPlugin are not required/used by WundergroundPlugin; they are ignored for compatibility with existing topics, but should be removed from topics when the opportunity arises.

As noted above, a WU license key is required (but for many applications, a free license suffices.)

This release is alpha quality - this plugin is not completely internationalized.

Plugin Installation Instructions

Note: You do not need to install anything on the browser to use this plugin. The following instructions are for the administrator who installs the plugin on the TWiki server.

Weather Underground requires a license key to use it's API. Free licenses are available, although for heavy use fees are required. To use this plugin, you must obtain a license key.

Weather Underground's website describes the options. At this writing, obtaining a key is a two-step process. Create an account, then obtain the license.

The plugin author has no connection to Weather Underground, and does not vouch for the service provided. You must determine whether the service is suitable for your needs, and obey the licensing restrictions that accompany your license. The plugin only provides an interface to the service from TWiki topics. Note that the attribution to Weather Underground is required by the license.
