Crate rspolib

PO and MO files manipulation library.

Port to Rust of the Python library polib. The implementation differs a bit to make it even better.

Quick start

Read and save a PO file

use rspolib::{pofile, Save};

let file = pofile("tests-data/obsoletes.po").unwrap();
for entry in file.translated_entries() {
    println!("{}", &entry.msgid);
}
file.save("tests-data/docs/pofile_save.po");

Read and save a MO file

// You can include the prelude to access to all the methods
use rspolib::{mofile, prelude::*};

let mut file = mofile("tests-data/all.mo").unwrap();
for entry in &file.entries {
    // All entries are translated in MO files
    println!("{}", entry.msgid);
}
file.save("tests-data/docs/mofile_save.mo");

Features

• Unicode Line Breaking formatting support.
• Correct handling of empty and non existent PO fields values.
• More detailed error handling parsing PO and MO files.
• Custom byte order MO files generation.

General view

• POFiles, contains POEntrys.
• MOFiles, contains MOEntrys.

Items of the same level can be converted between them, for example a POEntry can be converted to a MOEntry using MOEntry::from(&POEntry) because MOEntrys implement the From trait for &POEntry.

All of the conversions that make sense are implemented for all the structs. For example, to get the representation of a POFile just call to_string() or to get the binary representation of bytes of a MOFile calls as_bytes().
