Markdeep localization
Please try again to get the German translations for months, days, etc.
There are two ways to localize the keywords such as Table, Diagram, Monday, etc., from English to your favorite language. The first is to put a meta tag with a lang attribute in the document, such as
<meta lang="ru"charset="utf-8"
. If your favorite language isn't supported by Markdeep, just e-mail me a Javascript snippet with the appropriate translations and I'll add it (see the source code for examples). The second method is to manually set the markdeepOptions.lang field before you include the script in your document. When you've selected a language, keywords that you type such as “figure”, “listing”, etc., the names of days and months, and any text inserted by Markdeep such as “contents” will all be in that language.
