A Rust library to read, manipulate and write GNU gettext translation data in .po format.

Basic Concepts

A Message represents a translation of a text entry from the source language to a target language.

A Catalog holds a collection of Messages, and is stored in a .po file.

Example

Iterate over messages in a .po file

```rust use polib::po_file; use std::error::Error; use std::path::Path;

fn main() -> Result<(), Box> { let catalog = pofile::parse(Path::new("foo.po"))?; for message in catalog.messages() { if message.istranslated() { if message.issingular() { println!("{} => {}", message.msgid(), message.msgstr()?); } else { // message.isplural() println!("{} => {}", message.msgid(), message.msgstr_plural()?.join(", ")); } } else { println!("{} is untranslated", message.msgid()); } } Ok(()) } ```

Remove untranslated or fuzzy entries and save to another .po file

rust let mut catalog = po_file::parse(Path::new(&input_file))?; let mut filtered: usize = 0; for mut message in catalog.messages_mut() { if !message.is_translated() || message.is_fuzzy() { message.delete(); filtered += 1; } } po_file::write(&catalog, Path::new(&output_file))?; println!("{} untranslated or fuzzy translations removed.", filtered);

Fill in missing translations from some other translation service

rust let mut catalog = po_file::parse(Path::new(&input_file))?; for mut message in catalog.messages_mut() { if !message.is_translated() { if message.is_singular() { message.set_msgstr(/* some 3rdparty provided */translate(message.msgid()))?; } } } po_file::write(&catalog, Path::new(&output_file))?;

Compile a .po file to .mo format

rust mo_file::compile_from_po(Path::new(&input), Path::new(&output))?;
