//! Placeholder substitution.
//!
//! A template file is plain text with `__TOKEN__` markers. Substitution is a
//! sequence of string replacements rather than a template engine: the token
//! set is closed, every token is a single word, and a generated project has
//! to be readable as the file the developer will edit next.

use super::catalog::{Database, Stack};
use super::name::ProjectName;

/// Render a template by substituting the placeholder tokens.
///
/// `__DATABASE_URL__` is expanded before `__RUST_NAME__` because the default
/// connection string names the database after the crate.
