//!
//! A whitespace-aware quasiquoter for beautiful code generation.
//!
//! Central to genco are the [quote!] and [quote_in!] procedural macros which
//! ease the construction of [token streams].
//!
//! This project solves the following language-specific concerns:
//!
//! * **Imports** — Generates and groups [import statements] as they are used.
//!   So you only import what you use, with no redundancy. We also do our best
//!   to [solve namespace conflicts].
//!
//! * **String Quoting** — genco knows how to [quote strings]. And can even
//!   [interpolate] values *into* the quoted string if it's supported by the
//!   language.
//!
//! * **Structural Indentation** — The quoter relies on intuitive
//!   [whitespace detection] to structurally sort out spacings and indentation.
//!   Allowing genco to generate beautiful readable code with minimal effort.
//!   This is also a requirement for generating correctly behaving code in
//!   languages like Python where [indentation is meaningful].
//!
//! * **Language Customization** — Building support for new languages is a
//!   piece of cake with the help of the [impl_lang!] macro.
//!
//! <br>
//!
//! To support line changes during [whitespace detection], we depend on the
//! nightly [`proc_macro_span` feature]. On stable we can only detect column
//! changes.
//!
//! *Until this is stabilized* and you want fully functional whitespace
//! detection you must build and run projects using genco with a `nightly`
//! compiler. This is important for whitespace-sensitive languages like python.
//!
//! You can try the difference between:
//!
//! ```bash
//! cargo run --example rust
//! ```
//!
//! And:
//!
//! ```bash
//! cargo +nightly run --example rust
//! ```
//!
//! [`proc_macro_span` feature]: https://github.com/rust-lang/rust/issues/54725
//!
//! <br>
//!
//! ## Supported Languages
//!
//! The following are languages which have built-in support in genco.
//!
//! * [🦀 <b>Rust</b>][rust]<br>
//!   <small>[Example][rust-example]</small>
//!
//! * [☕ <b>Java</b>][java]<br>
//!   <small>[Example][java-example]</small>
//!
//! * [🎼 <b>C#</b>][c#]<br>
//!   <small>[Example][c#-example]</small>
//!
//! * [🐿️ <b>Go</b>][go]<br>
//!   <small>[Example][go-example]</small>
//!
//! * [🎯 <b>Dart</b>][dart]<br>
//!   <small>[Example][dart-example]</small>
//!
//! * [🌐 <b>JavaScript</b>][js]<br>
//!   <small>[Example][js-example]</small>
//!
//! * [🐍 <b>Python</b>][python]<br>
//!   <small>[Example][python-example]</small><br>
//!   **Requires a `nightly` compiler**
//!
//! <small>Is your favorite language missing? <b>[Open an issue!]</b></small>
//!
//! You can run one of the examples by:
//!
//! ```bash
//! cargo +nightly run --example rust
//! ```
//!
//! <br>
//!
//! ## Rust Example
//!
//! The following is a simple program producing Rust code to stdout with custom
//! configuration:
//!
//! ```rust,no_run
//! use genco::prelude::*;
//!
//! let hash_map = rust::import("std::collections", "HashMap");
//!
//! let tokens: rust::Tokens = quote! {
//!     fn main() {
//!         let mut m = #hash_map::new();
//!         m.insert(1u32, 2u32);
//!     }
//! };
//!
//! println!("{}", tokens.to_file_string()?);
//! # Ok::<_, genco::fmt::Error>(())
//! ```
//!
//! This would produce:
//!
//! ```rust,no_test
//! use std::collections::HashMap;
//!
//! fn main() {
//!     let mut m = HashMap::new();
//!     m.insert(1u32, 2u32);
//! }
//! ```
//!
