This is a followup / more specific variant of converting ops on the syntaxTree to https://codemirror.net/docs/ref/#state.ChangeSpec ?
I have the following problem: I have a Scheme/Lisp like language. I want to ensure () and [] and {} are always balanced.
Now, making changes on the syntaxTree and mapping them to changeSpec, in the general problem, we do not have a nice solution for.
I have a more specific question: if all I need to do is to delete nodes of syntaxTree, is there a simple way to do
input: list of nodes of syntaxTree to deleted
output: list of changeSpec
The basic idea here is – in the case of unbalanced () [] or {}, instead of trying to add to make it balanced, I’m just going to delete the spurious one.
