+To use custom CodeMirror assets (modes, themes, plugins) other than the ones predefined here you need to add those assets to the codemirror assets folder `src/assets/codemirror` If you need to add a mode added to the `modes` folder; same with the themes.

CodeMirror: APL mode

+
+
+
+APL mode
+
+
+
+
+ Simple mode that tries to handle APL as well as it can.
+ It attempts to label functions/operators based upon
+ monadic/dyadic usage (but this is far from fully fleshed out).
+ This means there are meaningful classnames so hover states can
+ have popups etc.
+
+ MIME types defined: text/apl
(APL code)

+ *
+ * $traversableInfo
+ * @define mutability
+ * @define traversableInfo
+ * This is a base trait of all kinds of $mutability Scala collections. It
+ * implements the behavior common to all collections, in terms of a method
+ * `foreach` with signature:
+ * {{{
+ * def foreach[U](f: Elem => U): Unit
+ * }}}
+ * Collection classes mixing in this trait provide a concrete
+ * `foreach` method which traverses all the
+ * elements contained in the collection, applying a given function to each.
+ * They also need to provide a method `newBuilder`
+ * which creates a builder for collections of the same kind.
+ *
+ * A traversable class might or might not have two properties: strictness
+ * and orderedness. Neither is represented as a type.
+ *
+ * The instances of a strict collection class have all their elements
+ * computed before they can be used as values. By contrast, instances of
+ * a non-strict collection class may defer computation of some of their
+ * elements until after the instance is available as a value.
+ * A typical example of a non-strict collection class is a
+ *
+ * `scala.collection.immutable.Stream` .
+ * A more general class of examples are `TraversableViews`.
+ *
+ * If a collection is an instance of an ordered collection class, traversing
+ * its elements with `foreach` will always visit elements in the
+ * same order, even for different runs of the program. If the class is not
+ * ordered, `foreach` can visit elements in different orders for
+ * different runs (but it will keep the same order in the same run).'
+ *
+ * A typical example of a collection class which is not ordered is a
+ * `HashMap` of objects. The traversal order for hash maps will
+ * depend on the hash codes of its elements, and these hash codes might
+ * differ from one run to the next. By contrast, a `LinkedHashMap`
+ * is ordered because it's `foreach` method visits elements in the
+ * order they were inserted into the `HashMap`.
