Unicode String Shortener

Try it out! Live at https://noguera.dev/unicode-string-shortener.

The idea of this project is to compress text in terms of bytes or characters used while maintaining its human readability. Using this program you can enter more text than intended into a limited-size form field.

For the intents of this project, anything that looks close enough to a latin letter to be readable is considered acceptable, even if it may have an entirely different meaning.

Here is an example of program functionality.

Enter string to shorten: aether
Input:                         aether               (6)
Shortest in bytes:             æther                (6)
Shortest in characters used:   æᵺer                 (4)

Structure

A human-readable list of shortenings used is available in map.tsv. The columns in that file are: unicode codepoint, unicode character, ascii equivalent strings. There can be more than one ascii equivalent string for a single unicode character, columns are added for each additional one. However, no two unicode characters can be translated to the same string (the program checks for this and will error).

To update the computer-readable list in map.bincode, delete the map.bincode file and run the program. A new bincode will be produced from map.tsv.

Usage

Online

Available online at https://noguera.dev/unicode-string-shortener. The program is compiled to webassembly and runs entirely client-side in your browser.

Command Line Interface

The program member of this workspace compiles to an executable program, unishorten, which by default takes a single argument that is the string to shorten. Alternatively, unishorten -i will run in interactive mode and prompt for input.

Shortens ascii strings by substituting unicode characters that look like more than one ascii character

Usage: unishorten [OPTIONS] [input]

Arguments:
  [input]  string to shorten

Options:
  -i, --interactive  interactive mode
  -h, --help         Print help information
  -V, --version      Print version information

Crate

You can also import the program folder of this repo as a library. This can be done with the command:

cargo add --git https://github.com/michaelnoguera/unicode-string-shortener unishorten

After running the command, your cargo.toml file should contain:

[dependencies]
unishorten = { git = "https://github.com/michaelnoguera/unicode-string-shortener", version = "0.1.0" }

Most users will want to instantiate a StringShortener rather than interacting with the various utility functions in the library.

use unishorten::StringShortener;

let Shortener = StringShortener::new();
let out = Shortener.shorten_by_chars(/* reference to input string */);

To customize the list of mappings, clone this repository, edit map.tsv, then delete map.bincode and run the command line program again. The bincode file will be regenerated from whatever the tsv file contains.

Installation/Development

Option 1: Compile locally

This assumes you have Rust installed.

1. Clone this repo. git clone https://github.com/michaelnoguera/unicode-string-shortener
2. Run cargo build to install dependencies and compile. This will take a long time the first time you run it on this project.
3. Run cargo run to run the program.

Option 2: Clone into a local Docker devcontainer with VS Code

If you use VS Code and have Docker installed, you can clone this repo into a devcontainer that reproduces my build.

1. Install the Dev Containers extension, if not already installed.

2. Then paste this address into your browser's address bar (Github disables vscode:// links)

   vscode://ms-vscode-remote.remote-containers/cloneInVolume?url=https://github.com/michaelnoguera/unicode-string-shortener

   If you don't feel like clicking my strange-looking links, you can alternatively Open VS Code, open the Command Pallete (Ctrl/Cmd + Shift + P), select "Dev Containers: Clone Repository in Container Volume" and specify this repo https://github.com/michaelnoguera/unicode-string-shortener.

3. Wait for the container to set itself up. cargo build will run automatically to configure dependencies.

4. Run the program with cargo run.

Option 3: Clone into a cloud devcontainer with Github Codespaces

To open this repository in Codespaces, use the button below.

Warning

Bad news: This could cost money.

Good news: You get 60 hours free per month (on the least powerful option), so if you are just poking around and want to check out this project for a minute or two, it will almost certainly be free.

1. Click this link

   

2. Wait for the container to set itself up (less than 5 min). cargo build runs automatically to configure dependencies.

3. Run the program with cargo run.
