Full2Half

A simple project to allow conversion of full-width characters to half-width characters and vice versa, which supplies a library and CLI binary.

Command-Line Interface

The binary has three main functions.

Convert a string directly:

full2half "Ｈｅｌｌｏ　Ｗｏｒｌｄ！"

Do the conversion on a file by overwriting or copying:

This will overwrite the file.

full2half -f "file_to_convert.txt"

This will create a copy with this naming scheme: "[File Name] ([Duplicate Counter])[ext]"

full2half -c -f "file_to_convert.txt"

Customize Behaviour:

If needed you can also ignore specific characters like so:

full2half -i "ｅ" "！" -- "Ｈｅｌｌｏ　Ｗｏｒｌｄ！"

Or ignore specific character sets by using the specified flags, get more info by running:

full2half -h

Installation

To use this library in your Rust project, simply add the following line to your Cargo.toml file:

[dependencies]
full2half = { version = "0.1.0" }

To install the full2half binary locally, simply run the following command:

cargo install full2half

The binary will be downloaded from crates.io and compiled by cargo. After installation you can simply use the full2half binary from the command line.

Usage

Simply import the CharacterWidth trait and you are ready to go:

use full2half::CharacterWidth;

let full_width_string = "Ｈｅｌｌｏ　Ｗｏｒｌｄ！";
let half_width_string = "Hello World!";

println!("{}", full_width_string.to_half_width());
println!("{}", half_width_string.to_full_width());

See more details in the docs.
