oohid

Description

oohid is a fast and efficient command-line interface (CLI) tool for generating Universally Unique Identifiers (UUIDs) in various formats. It allows users to output UUIDs directly to a file or standard output (stdout). Features options for custom formatting, duplicate checking, and verbose output.

Features

• Generate multiple UUIDs in a single command.
• Custom formatting options for UUIDs.
• Output to a file or stdout.
• Check for and remove duplicate UUIDs.
• Verbose mode for additional output information.

Characteristics

• Pretty fast, as it is dependent on the work of wiser people. Uses Rayon for embarassingly parallel tasks, probably some more optimization work to do. SIMD or assembly-level stuff or cache optimization. ~1 mil/s on my MacBook Pro w. M2 Pro.
• Formatting options suitable for Python/Rust.
• For the extra-paranoid, duplicate checking.

Installation

To install oohid, ensure you have Rust and Cargo installed on your system. Then run the following command:

cargo install oohid

Usage

Basic Usage

To generate a single UUID and print it to stdout:

oohid

Generating Multiple UUIDs

Generate 5 UUIDs:

oohid --count 5

or

oohid -c 5

Specifying Format

Specify a custom format for the UUIDs (ul for bare with comma, q for quoted, etc.):

oohid --count 5 --format ul

or

oohid -c 5 -f ul

Output to a File

Direct the output to a file:

oohid --count 10 --output uuids.txt

or

oohid -c 10 -o uuids.txt

Checking for Duplicates

Check and remove duplicate UUIDs:

oohid -c 100 --check

Verbose Output

Display benchmarking and checking results:

oohid -c 100000000 -f qlbl -o uuids.txt --check --verbose
