@ -8,4 +8,4 @@ Here are some key ideas of how the plan will be accomplished.
* Implementation will start with Husht == Rust, and use the tree-sitter grammar for Rust to produce tree-sitter parse trees for "Husht" (=Rust) code, which will be transformed into essentially the same trees as rustc_parse would produce (in Rust's own ast structure), and then use the rustfmt code generator to produce Rust code. In the other direction, we will use rustc_parse itself, and likely use algorithms from the prettyplease pretty printer to convert that to a tree-sitter concrete syntax tree, from which it is of course easy to generate "Husht" code. * Implementation will start with Husht == Rust, and use the tree-sitter grammar for Rust to produce tree-sitter parse trees for "Husht" (=Rust) code, which will be transformed into essentially the same trees as rustc_parse would produce (in Rust's own ast structure), and then use the rustfmt code generator to produce Rust code.

* Once that roundtrip is working, we will fork and diverge the Husht tree-sitter parse from its starting point identical to the Rust tree-sitter parser, to implement the syntax that will make Husht a pleasure to use. * Once that roundtrip is working, we will fork and diverge the Husht tree-sitter parse from its starting point identical to the Rust tree-sitter parser, to implement the syntax that will make Husht a pleasure to use.
