spellout

spellout is a Rust library and command-line tool for converting text into various phonetic codes, also known as spelling alphabets. It supports a wide range of predefined alphabets like the NATO phonetic alphabet, as well as custom alphabets defined by the user.

Features

• Dual Functionality: Usable as both a command-line tool (spellout) and a Rust library.
• Wide Range of Alphabets: Comes with many predefined phonetic alphabets, including international and country-specific ones.
• Customizable: Create your own phonetic alphabets by providing a base alphabet with substitutions or by loading definitions from a file.
• Unicode Normalization: Optional feature to normalize input strings for consistent conversion.
• Simple & Fast: Lightweight and designed for quick conversions.

CLI Installation & Usage

⚓ Installation

You can install the CLI tool using Cargo:

brew install tamada/tap/spellout

Basic Usage

To convert a string to the default NATO phonetic alphabet:

spellout "Hello World"

Output:

H    Hotel 
e    Echo 
l    Lima 
l    Lima 
o    Oscar 
     
W    Whiskey 
o    Oscar 
r    Romeo 
l    Lima 
d    Delta 

Specify a Different Alphabet

Use the -c or --code option to specify a different phonetic alphabet.

spellout -c uk "Radio"

Output:

R    Robert 
a    Able 
d    Dog 
i    Item 
o    Orange 

Use a Custom Alphabet File

You can define your own alphabet in a file and use it with the --input option. The file should contain character,codeword pairs. See testdata/custom_codes.txt for an example.

spellout --input testdata/custom_codes.txt "Test"

Output:

T    Target
e    Echo-Six
s    Sector
t    Target

List Available Alphabets

To see a list of all supported predefined alphabets, use the -l or --list flag:

spellout -l

Output:

chp
english
eu
france
indonesia
international
italia
nato
netherlands
philippines
sweden
uk
usaairpots
japanese

🐳 Docker Available

docker run --rm -it ghcr.io/tamada/spellout:latest "Hello World"
H    Hotel
e    Echo
l    Lima
l    Lima
o    Oscar

fn main() {
    // Build the UK phonetic alphabet
    let codes = CodesBuilder::build(PhoneticCode::Uk);

    // Convert a word and print the results
    let word = "Hello";
    for (char, code) in codes.convert(word) {
        if let Some(c) = code {
            println!("{}    {}", char, c.code());
        } else {
            println!("{} ", char);
