+"""
+Format a pretty string of a `SoupSieve` object for easy debugging.
+
+This won't necessarily support all types and such, and definitely
+not support custom outputs.
+
+It is mainly geared towards our types as the `SelectorList`
+object is a beast to look at without some indentation and newlines.
+The format and various output types is fairly known (though it
+hasn't been tested extensively to make sure we aren't missing corners).
+
+Example:
+-------
+```
+>>> import soupsieve as sv
+>>> sv.compile('this > that.class[name=value]').selectors.pretty()
+SelectorList(
+    selectors=(
+        Selector(
+            tag=SelectorTag(
+                name='that',
+                prefix=None),
+            ids=(),
+            classes=(

+                        '^value$'),
