*More detailed description of usage and possibilities:*
Instead of using label tags directly, they are prepended by the $locale
tag. $locale provides a language dependent label string if some is
available und otherwise the entry from weewx.conf or skin.conf
Example:
$locale.obs.label.outTemp
The extension looks for an entry in the appropriate localization file. If
it finds one it returns it. If it finds no entry the value from skin_dict
(weewx.conf or skin.conf) is returned.
For template dependent labels use Cheetah variable as parameter to the
$locale tag.
Example:
#set $page = "mypage"
$locale(tmpl=$page).html_description
This tag is first looked up in the [Templates] section of the localization
file in the subsection defined by (in this example) $page. If it is found
there, it is used. If it is not found there, the entry in section
[Labels][[Generic]] is used, either from skin.conf or weewx.conf. In
general you would have the #set line at the beginning of the template file
and the $locale line within some #include file, called from that template
file. It replaces long #if - #if else etc. constructs as found in several
skins today by a single line.
To make lookup more flexible, it is also possible to provide the label
entry as a parameter to $locale.
Example:
#set $mylabel = "outTemp"
#set $xxx = 'obs.label'+$mylabel
$locale(tag=$xxx)
That looks for $locale.obs.label.outTemp, too. It may be useful in Cheetah
loops.
The extension needs an additional entry called 'lang_file' directly in the
skin section of weewx.conf. It points to the localization file to use.
Relative paths are relative to the skin directory.
The localization file has the same structure as the skin.conf file. Entries
that depend on language need to be defined there, only. Other entries
remain defined in weewx.conf or skin.conf
The localization file is not restricted to "Extras" and "Labels" section,
but can process all sections of the file.
