+
+***************
+Source Mappings
+***************
+
+As part of the AST output, the compiler provides the range of the source
+code that is represented by the respective node in the AST. This can be
+used for various purposes ranging from static analysis tools that report
+errors based on the AST and debugging tools that highlight local variables
+and their uses.
+
+Furthermore, the compiler can also generate a mapping from the bytecode
+to the range in the source code that generated the instruction. This is again
+important for static analysis tools that operate on bytecode level and
+for displaying the current position in the source code inside a debugger
+or for breakpoint handling.
+
+Both kinds of source mappings use integer indentifiers to refer to source files.
+These are regular array indices into a list of source files usually called
+``"sourceList"``, which is part of the combined-json and the output of
+the json / npm compiler.
+
+The source mappings inside the AST use the following
+notation:
+
+``s:l:f``
+
+Where ``s`` is the byte-offset to the start of the range in the source file,
+``l`` is the length of the source range in bytes and ``f`` is the source
+index mentioned above.
+
+The encoding in the source mapping for the bytecode is more complicated:
+It is a list of ``s:l:f:j`` separated by ``;``. Each of these
+elements corresponds to an instruction, i.e. you cannot use the byte offset
+but have to use the instruction offset or PC (program counter).
+The fields ``s``, ``l`` and ``f`` are as above and ``j`` can be either
+``i``, ``o`` or ``-`` signifying whether a jump instruction goes into a
+function, returns from a function or is a regular jump as part of e.g. a loop.
+
+In order to compress these source mappings especially for bytecode, the
+following rules are used:
+
+ - If a field is empty, the value of the preceding element is used.
+ - If a ``:`` is missing, all following fields are considered empty.
+
+This means the following source mappings represent the same information:
+
+``1:2:1;1:9:1;2:1:2;2:1:2;2:1:2``
+
+``1:2:1;:9;2::2;;``
