|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 1184: Start structured editing API r=matklad a=matklad I think I finally understand how to provide nice, mutable structured editing API on top of red-green trees. The problem I am trying to solve is that any modification to a particular `SyntaxNode` returns an independent new file. So, if you are editing a struct literal, and add a field, you get back a SourceFile, and you have to find the struct literal inside it yourself! This happens because our trees are immutable, but have parent pointers. The main idea here is to introduce `AstEditor<T>` type, which abstracts away that API. So, you create an `AstEditor` for node you want to edit and call various `&mut` taking methods on it. Internally, `AstEditor` stores both the original node and the current node. All edits are applied to the current node, which is replaced by the corresponding node in the new file. In the end, `AstEditor` computes a text edit between old and new nodes. Note that this also should sole a problem when you create an anchor pointing to a subnode and mutate the parent node, invalidating anchor. Because mutation needs `&mut`, all anchors must be killed before modification. Co-authored-by: Aleksey Kladov <[email protected]>

Note: Right now it only handle a poison macro in a single crate, such that if other crate try to call that macro, the whole process will do again until it became poisoned in that crate.

Handle `*+` matcher properly 3. Add missing separator in rhs macro expansion. 4. Fixed bug in single token with empty delimiter subtree case. It is because the current `mbe_expander` will create an delimiter subtree for each expansion. But in `tt` case, all puncts expansion will be incorrect because of it. 5. Fixed lifetime bug 6. Add more information on parse_macro fail 7. Add tests for above. Co-authored-by: Edwin Cheng <[email protected]>
