Space2underscore

A CLI tool that converts spaces into underscores. Useful for creating or renaming Git branches.

Requirements

Ruby >= 2.4.0
Git

Installation

$ gem install space2underscore

Usage

Create a new branch

Use the -c (--create) option to create a new Git branch with spaces converted to underscores.

$ s2u new branch -c
=> Switched to a new branch 'new_branch'

Rename an existing branch

Use $(s2u ...) as a subcommand.

$ git branch -m $(s2u renamed branch)

Print the converted string

Without any options, the converted string is printed to stdout. By default, the output is downcased.

$ s2u Hello World
hello_world

Preserve original case

Use the -r (--raw) option to keep the original letter casing.

$ s2u Hello World -r
Hello_World

Options

Option	Short	Description
`--create`	`-c`	Create a new Git branch with the converted name
`--raw`	`-r`	Preserve original letter casing (skip downcase)

Caution

This is a command line tool. DO NOT include this module in other Ruby applications, as it uses the system command internally, which may introduce command injection vulnerabilities.
