# Vim engine evolution and improvements
|
|
|
|
- We have a mechanism to understand if the command is writable or not. However, this mechanism requires an
|
|
instance of the editor, what makes idea of splitting editor into mutable and immutable useless.
|
|
We need an additional step in our engine to determine if the command is writable without acquiring the editor.
|
|
- At the moment, we can move the caret at any moment of the code. The caret is mutable, so in the code you rely on the
|
|
fact that the caret has changed. This is not true for the Fleet editor, where the caret movement is in fact creation
|
|
of the new caret.
|
|
- Also, we can move the caret to any position at any moment of time. This would be better if the actions were only
|
|
calculating the new position and this change was applied at once. This is already work very similar to that,
|
|
but this approach should be reviewed with the fact that we create a new caret instead of moving the old one.
|
|
- Tests sharing: IdeaVim has over 3500 tests. We should find a way to efficently share tests between different
|
|
implementations that run tests on different editors.

|
|
- Motion group has a lot of `move..` methods that don't actually move anything
|
|
- Make non-null editor in `executeAction` method |
