+# nanoc-dejure
+
+*nanoc* filter implementation of the *dejure.org*
+[legal integration service](https://dejure.org/vernetzung.html),
+adapted from the PHP reference implementation
+at <https://dejure.org/vernetzung/vernetzungsfunktion.zip>.
+
+This *nanoc* filter will add links to any references of German
+(federal) law or jurisprudence to the corresponding bill or statute
+or the appropriate case at the *dejure.org* legal information
+service, using the public API of the legal integration service offered
+by *dejure.org*. Results will be cached for (by default) 7 days to
+reduce *nanoc* runtime.
+
+## Installation / Usage
+
+Just drop the `dejure.rb` file into your `lib/filters/` directory and
+add the filter to a `compile` rule in your `Rules` file.
+
+Please set the `base_url` of your site in the *nanoc.yaml*
+configuration file, by adding e.g. `base_url: http://mysite.example`
+at the end of the file. This is used as a service identification tag
+when using the API.
+
+The filter will use the `tmp/dejure-org/` directory for its cache.
+
+Adding `<!-- no-dejure -->` somewhere in a source file will disable
+the filter for that file.
+
+## Parameters
+
+This filter accepts the following parameters:
+
+* `format` (`weit` or `schmal`, Default: `weit`)  
+  Small (*schmal*) format will add the link just to the number of the
+  article or section; wide (*weit*) format will add the link to the
+  whole reference: "**§ 35** Abs. 1 StVO" or "**§ 35 Abs. 1 StVO**".
+
+* `buzer` (`0` or `1`, Default: `1`)  
+  If set to `true` (`1`) references to regulations not present at
+  *dejure.org* will get a link to the *buzer.de* legal information
+  service, covering all of the German Federal Law.
+
+* `target` (Default: `''`)  
+  Add this to the `target` attribute of the `<a>` elements that are
+  generated by the API, e.g. `<a href="..." target="_blank">`.
+
+* `class` (Default: `''`)  
+  Add this to the `class` attribute of the `<a>` elements that are
+  generated by the API, e.g. `<a href="..." class="_dejure">`.
+
+* `cache_days` (Default: `7`)  
+  The cache validity (in days).
