📻 edio

A command-line tool that opens stdin in your editor, lets you edit the content interactively, and outputs the result to stdout.

Installation

curl --proto '=https' --tlsv1.2 -LsSf https://github.com/muleyuck/edio/releases/latest/download/edio-installer.sh

brew install muleyuck/tap/edio

Usage

edio [OPTIONS]

Options

• -e, --extension <EXTENSION>: Set file extension for the temporary file (default: txt)

Examples

Basic usage: Edit stdin and print to stdout

echo "Hello, World!" | edio

Edit and save to a file

echo "Initial content" | edio > output.txt

Edit stdin in specific editor(e.g. VSCode)

export EDITOR="code --wait"
echo "Initial content" | edio > output.txt

1. $GIT_EDITOR environment variable
2. $VISUAL environment variable
3. $EDITOR environment variable
4. git config core.editor
5. vi (fallback)

Requirements

• Unix-like operating system (Linux, macOS)
• Access to /dev/tty when output is piped
