Struct Extractor 

pub struct Extractor { /* private fields */ }

Struct that extracts all messages from source code and can print them to a .pot file.

This file can then be used as a starting point to begin translation. It should be relatively similar to gettext generated files.

Example

use crowbook_intl::Extractor;
let mut extractor = Extractor::new();
extractor.add_messages_from_dir("src/").unwrap();
println!("{}", extractor.generate_pot_file());

Note

This struct only add messages that are considered as needing localization, that is, the first argument of calls so lformat! macro.

Implementations

impl Extractor

pub fn new() -> Extractor

Create a new, empty extractor

pub fn original_strings<'a>(&'a self) -> &'a HashMap<String, String>

Returns a hashmap mapping the original strings (as used by lformat!) to escaped strings. Only contains strings that are different and must thus be handled.

pub fn add_messages_from_file<P: AsRef<Path>>(&mut self, file: P) -> Result<()>

Add all the messages contained in a source file

pub fn add_messages_from_dir<P: AsRef<Path>>(&mut self, dir: P) -> Result<()>

Add messages from all .rs files contained in a directory (walks through subdirectories)

pub fn generate_pot_file(&self) -> String

Generate a pot-like file from the strings extracted from all files (if any)

pub fn write_pot_file(&mut self, file: &str) -> Result<()>

Write a pot-like file to specified location
