Crate ferrocat

Expand description

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.

§Examples

use ferrocat::{parse_icu, parse_po};

let po = parse_po("msgid \"Hello\"\nmsgstr \"Hallo\"\n")?;
let icu = parse_icu("Hello {name}")?;

assert_eq!(po.items[0].msgid, "Hello");
assert_eq!(icu.nodes.len(), 2);

use ferrocat::{
    CompileSelectedCatalogArtifactOptions, CompiledCatalogIdIndex, CompiledKeyStrategy,
    ParseCatalogOptions, compile_catalog_artifact_selected, parse_catalog,
};

let source = parse_catalog(ParseCatalogOptions {
    content: "msgid \"Hello\"\nmsgstr \"Hello\"\n",
    source_locale: "en",
    locale: Some("en"),
    ..ParseCatalogOptions::default()
})?
.into_normalized_view()?;
let requested = parse_catalog(ParseCatalogOptions {
    content: "msgid \"Hello\"\nmsgstr \"Hallo\"\n",
    source_locale: "en",
    locale: Some("de"),
    ..ParseCatalogOptions::default()
})?
.into_normalized_view()?;
let index = CompiledCatalogIdIndex::new(&[&requested, &source], CompiledKeyStrategy::FerrocatV1)?;
let compiled_ids = index.iter().map(|(id, _)| id.to_owned()).collect::<Vec<_>>();
let compiled = compile_catalog_artifact_selected(
    &[&requested, &source],
    &index,
    &CompileSelectedCatalogArtifactOptions {
        requested_locale: "de",
        source_locale: "en",
        compiled_ids: &compiled_ids,
        ..CompileSelectedCatalogArtifactOptions::default()
    },
)?;

assert_eq!(compiled.messages.len(), 1);

use ferrocat::{CatalogAuditOptions, ParseCatalogOptions, audit_catalogs, parse_catalog};

let source = parse_catalog(ParseCatalogOptions {
    content: "msgid \"Checkout\"\nmsgstr \"Checkout\"\n",
    source_locale: "en",
    locale: Some("en"),
    ..ParseCatalogOptions::default()
})?
.into_normalized_view()?;
let target = parse_catalog(ParseCatalogOptions {
    content: "",
    source_locale: "en",
    locale: Some("de"),
    ..ParseCatalogOptions::default()
})?
.into_normalized_view()?;
let report = audit_catalogs(&[&source, &target], &CatalogAuditOptions::new("en"))?;

assert!(report.has_errors());
