As the GitHub Copilot is placed right in the editor component, the IdeaVim's actions are also collected. Action promoter promotes the IdeaVim's action and, since the data context has the editor, executes a Vim's actions like backspace.
Now we make sure that IdeaVim works only in the actual editor.
Since this change may affect some places where the IdeaVim used to work, but won't work now (this will be a surprise), a registry key is introduced to help the users that face this problem.
The `editorInFocus` used the weak reference in order to avoid editor leaks. However, if the user is unlucky, the GC may be called in between the console closing and switching focus to the new editor. In this case, the logic breaks and the Editor remains in the insert mode.
Now, we store only the required information about the last used editor.
This commit fixes 2 bugs at once:
1. Correctly trim surround with closing brackets motion, e.g.: `cs()`.
It should trim all surrounding white space or leave things unchanged if
there's no space.
For example cases like these:
"( ${c}foo )" // single spaces
"( ${c}foo )" // multiple spaces
"( ${c}foo)" // assymetric spaces
"(${c} )" // single space without text
"(${c} )" // multiple spaces without text
Should trim white spaces into these results accordingly:
"${c}(foo)"
"${c}(foo)"
"${c}(foo)"
"${c}()"
"${c}()"
In case of no spaces - they should be left unchanged, e.g.:
"(${c}foo)" // no spaces around the word
"(${c})" // empty parenthesis
2. Leave empty parenthesis unchanged. IdeaVim now deleted them instead.
**Context**:
In vim surround extendsion closing brackets (`}, ], )`) should remove
whitespace when using `cs` movement.
Example:
- Before: `{ example }`
- Movement: `cs{}`
- After: `{example}`
This was because were replaced with a string from `SURROUND_PAIRS` map,
which does not have any context about removing characters.
**Solution**:
Inspired from VSCode's VIM plugin[^1], I have introduced new class
`SurroundPair` that will carry this context about need to trim
characters.
**Disclaimer**:
I have never written in `Kotlin` so solution may be not use best
practices, though at least this PR seems to fix the problem and tests
are passing.
