#![cfg_attr(docsrs, feature(doc_cfg))]
#![warn(missing_docs, rustdoc::broken_intra_doc_links)]
//! Public Rust entry point for the `ferrocat` workspace.
//!
//! This crate re-exports the primary API surface from the lower-level
//! `ferrocat-po` and `ferrocat-icu` crates so application code can depend on a
//! single package.
//!
//! # Feature flags
//!
//! The default feature set is `full`, which enables the complete current API
//! surface through `catalog` and `serde`.
//!
//! - `catalog` exposes high-level catalog parsing, updates, combining, audits,
//!   machine-translation metadata, plural handling, FCL storage, and runtime
//!   artifact compilation.
//! - `serde` enables serde support in the re-exported `ferrocat-po` and
//!   `ferrocat-icu` types.
//! - `compile`, `mt`, and `plurals` are reserved subsystem aliases. Today they
//!   imply `catalog`; they do not reduce or split the catalog API surface.
//!
//! Use `default-features = false` for low-level PO and ICU parsing without the
//! catalog layer. Enabling `compile`, `mt`, or `plurals` currently has the same
//! dependency effect as enabling `catalog`.
//!
//! # Examples
//!
//! ```rust
//! use ferrocat::{icu, po};
//!
//! let po = po::parse_po("msgid \"Hello\"\nmsgstr \"Hallo\"\n")?;
//! let icu = icu::parse_icu("Hello {name}")?;
//!
//! assert_eq!(po.items[0].msgid, "Hello");
//! assert_eq!(icu.nodes.len(), 2);
//! # Ok::<(), Box<dyn std::error::Error>>(())
//! ```
//!
//! ```rust
//! use ferrocat::catalog::{
//!     CompileSelectedCatalogArtifactOptions, CompiledCatalogIdIndex, CompiledKeyStrategy,
//!     ParseCatalogOptions, compile_catalog_artifact_selected, parse_catalog,
//! };
//!
//! let source = parse_catalog(
//!     ParseCatalogOptions::new("msgid \"Hello\"\nmsgstr \"Hello\"\n", "en").with_locale("en"),
//! )?
//! .into_normalized_view()?;
//! let requested = parse_catalog(
//!     ParseCatalogOptions::new("msgid \"Hello\"\nmsgstr \"Hallo\"\n", "en").with_locale("de"),
//! )?
//! .into_normalized_view()?;
//! let index = CompiledCatalogIdIndex::new(&[&requested, &source], CompiledKeyStrategy::FerrocatV1)?;
//! let compiled_ids = index.iter().map(|(id, _)| id).collect::<Vec<_>>();
//! let compiled = compile_catalog_artifact_selected(
//!     &[&requested, &source],
//!     &index,
//!     &CompileSelectedCatalogArtifactOptions::new("de", "en", &compiled_ids),
//! )?;
//!
//! assert_eq!(compiled.messages.len(), 1);
//! # Ok::<(), Box<dyn std::error::Error>>(())
//! ```
//!
//! ```rust
//! use ferrocat::catalog::{
//!     CatalogAuditOptions, ParseCatalogOptions, audit_catalogs, parse_catalog,
//! };
//!
//! let source = parse_catalog(
//!     ParseCatalogOptions::new("msgid \"Checkout\"\nmsgstr \"Checkout\"\n", "en").with_locale("en"),
//! )?
//! .into_normalized_view()?;
//! let target = parse_catalog(ParseCatalogOptions::new("", "en").with_locale("de"))?
//! .into_normalized_view()?;
//! let report = audit_catalogs(&[&source, &target], &CatalogAuditOptions::new("en"))?;
//!
//! assert!(report.has_errors());
//! # Ok::<(), Box<dyn std::error::Error>>(())
//! ```
