- class ChangesTracker extends EventEmitter
- # The purpose of this class is to track a set of inserts and deletes to a document, like
- # track changes in Word. We store these as a set of ShareJs style ranges:
- # {i: "foo", p: 42} # Insert 'foo' at offset 42
- # {d: "bar", p: 37} # Delete 'bar' at offset 37
- # We only track the inserts and deletes, not the whole document, but by being given all
- # updates that are applied to a document, we can update these appropriately.
- #
- # Note that the set of inserts and deletes we store applies to the document as-is at the moment.
- # So inserts correspond to text which is in the document, while deletes correspond to text which
- # is no longer there, so their lengths do not affect the position of later offsets.
- # E.g.
- # this is the current text of the document
- # |-----| |
- # {i: "current ", p:12} -^ ^- {d: "old ", p: 31}
- #
- # Track changes rules (should be consistent with Word):
- # * When text is inserted at a delete, the text goes to the left of the delete
- # I.e. "foo|bar" -> "foobaz|bar", where | is the delete, and 'baz' is inserted
- # * Deleting content flagged as 'inserted' does not create a new delete marker, it only
- # removes the insert marker. E.g.
- # * "abdefghijkl" -> "abfghijkl" when 'de' is deleted. No delete marker added
- # |---| <- inserted |-| <- inserted
- # * Deletes overlapping regular text and inserted text will insert a delete marker for the
- # regular text:
- # "abcdefghijkl" -> "abcdejkl" when 'fghi' is deleted
- # |----| |--||
- # ^- inserted 'bcdefg' \ ^- deleted 'hi'
- # \--inserted 'bcde'

- # "abcghijkl" -> "ahijkl" when 'bcg is deleted'

+ # The purpose of this class is to track a set of inserts and deletes to a document, like
+ # track changes in Word. We store these as a set of ShareJs style ranges:
+ # {i: "foo", p: 42} # Insert 'foo' at offset 42
+ # {d: "bar", p: 37} # Delete 'bar' at offset 37
+ # We only track the inserts and deletes, not the whole document, but by being given all
+ # updates that are applied to a document, we can update these appropriately.
+ #
+ # Note that the set of inserts and deletes we store applies to the document as-is at the moment.
+ # So inserts correspond to text which is in the document, while deletes correspond to text which
+ # is no longer there, so their lengths do not affect the position of later offsets.
+ # E.g.
+ # this is the current text of the document
+ # |-----| |
+ # {i: "current ", p:12} -^ ^- {d: "old ", p: 31}
+ #
+ # Track changes rules (should be consistent with Word):
+ # * When text is inserted at a delete, the text goes to the left of the delete
+ # I.e. "foo|bar" -> "foobaz|bar", where | is the delete, and 'baz' is inserted
+ # * Deleting content flagged as 'inserted' does not create a new delete marker, it only
+ # removes the insert marker. E.g.
+ # * "abdefghijkl" -> "abfghijkl" when 'de' is deleted. No delete marker added
+ # |---| <- inserted |-| <- inserted
+ # * Deletes overlapping regular text and inserted text will insert a delete marker for the
+ # regular text:
+ # "abcdefghijkl" -> "abcdejkl" when 'fghi' is deleted
+ # |----| |--||
+ # ^- inserted 'bcdefg' \ ^- deleted 'hi'
+ # \--inserted 'bcde'
+ # * Deletes overlapping other deletes are merged. E.g.
+ # "abcghijkl" -> "ahijkl" when 'bcg is deleted'
+ # | <- delete 'def' | <- delete 'bcdefg'
+ # * Deletes by another user will consume deletes by the first user
+ # * Inserts by another user will not combine with inserts by the first user. If they are in the

+ * The value in a byte indicates a command, a number, or subsequent bytes
+ * that are to be interpreted in a special way.
+ *
+ * CharString Number Encoding:
+ * A CharString byte containing the values from 32 through 255 inclusive
+ * indicate an integer. These values are decoded in four ranges.
+ *
+ * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
+ * indicate the integer v - 139. Thus, the integer values from -107 through
+ * 107 inclusive may be encoded in single byte.
+ *
+ * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
+ * indicates an integer involving the next byte, w, according to the formula:
+ * [(v - 247) x 256] + w + 108
+ *
+ * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
+ * indicates an integer involving the next byte, w, according to the formula:
+ * -[(v - 251) * 256] - w - 108
+ *
+ * 4. A CharString containing the value 255 indicates that the next 4 bytes
+ * are a two complement signed integer. The first of these bytes contains the
+ * highest order bits, the second byte contains the next higher order bits
+ * and the fourth byte contain the lowest order bits.
+ *
+ *
+ * CharString Command Encoding:
+ * CharStrings commands are encoded in 1 or 2 bytes.
+ *
+ * Single byte commands are encoded in 1 byte that contains a value between
+ * 0 and 31 inclusive.
+ * If a command byte contains the value 12, then the value in the next byte
+ * indicates a command. This "escape" mechanism allows many extra commands
+ * to be encoded and this encoding technique helps to minimize the length of
+ * the charStrings.
