tweld 1.0.0

Dynamic identifier generation for Rust macros. Tweld provides a flexible @[] syntax to "fuse" strings, case-conversions, and logic directly into your generated source code.

//! > *You can read it as tiny-weld, token-weld, or just tweld. The important thing is that it compiles.*
//!  
//! Tweld is a procedural macro toolkit and naming DSL for Rust. It lets you dynamically generate, modify, and compose identifiers directly in your source code using a clean `@[]` syntax — because sometimes the identifier you need doesn't quite exist yet, and writing a full proc-macro just to rename a function feels like bringing a freight train to post a letter.
//! One can only hope the syntax is clean and intuitive enough.
//!
//! ```rust,ignore
//! weld!("## @[(the idea | title)]");
//! ```
//!  
//! The name comes from the idea of fusing tokens together. It started as a tool for writing macros for macros (which sounds recursive, because it is), and then grew somewhat beyond its original remit.
//! See [`weld!`] for full documentation.
