/* TODO Known Issues
|
|
|
* 1. ChainPad diff is not completely accurate: we're not aware of the other user's cursor
|
|
|
position so if they insert an "a" in the middle of "aaaaa", the diff will think that
|
|
|
the "a" was inserted at the end of this sequence. This is not an issue for the content
|
|
|
but it will cause issues for the colors
|
|
|
2. ChainPad doesn't always provide the good result in case of conflict (?)
|
|
|
e.g. Alice is inserting "pew" at offset 10, Bob is removing 1 character at offset 10
|
|
|
The expected result is to have "pew" and the following character deleted
|
|
|
In some cases, the result is "ew" inserted and the following character not deleted
