The introduction in README.md was updated to provide a more hands-on and interactive description of the tutorial, highlighting both declarative and procedural macros.
Add a detailed overview of procedural macros, including their security considerations and the technical constraints of proc-macro crates. Introduce the core ecosystem tools (syn, quote, proc-macro2) and outline the learning path for this chapter.
- Create token_stream.md with an interactive example. - Create proc_macro2_syn_quote.md to introduce the tool ecosystem. - Update SUMMARY.md to include these new sections.
Expand on the roles of `proc-macro2`, `syn`, and `quote` crates in `proc_macro2_syn_quote.md`. Add a practical code example for parsing `TokenStream` into a syntax tree. Correct the terminology in `token_stream.md` from "AST" to the more accurate "TokenTree".
Add a dedicated chapter for Syntax Trees in procedural macros. This includes: - Moving basic syntax tree examples to a new file. - Adding details on parsing tokens, keywords, and standard syn nodes. - Demonstrating custom parsing via closures and the Parse trait. - Updating SUMMARY.md to link the new section.
Add a new chapter to the tutorial explaining Spans in Rust procedural macros. Includes examples comparing coarse-grained spans from `quote!` with precise spans from `TokenStream::from_str`. - Create src/procedural_macros/span.md - Update src/SUMMARY.md to include the new section
- Include a new chapter explaining the quote crate and its syntax. - Add comparisons between macro_rules! and quote!. - Update SUMMARY.md and cross-reference from token_stream.md.
Marked multiple rust code blocks in procedural macro chapters with `compile_fail` to prevent mdbook/rustdoc from failing during tests. These snippets often require a proc-macro environment or specific dependencies that are not available in the doc-test context.
