wtf is gist?

Gist is a command-line tool that lets you quickly share snippets of code or text through GitHub's Gist service without ever leaving your terminal. Instead of copying a file's contents, opening a browser, navigating to the website, and pasting it in, you just run a single command and get back a shareable link. The tool works by reading a file or text you pass to it and uploading that content directly to GitHub. You can pipe text into it, give it a specific file, or even type text directly into the terminal. It supports creating private snippets, guessing or letting you set the programming language for syntax highlighting, and uploading multiple files at once. To use it, you authenticate with your GitHub username and a personal access token, which you can store as environment variables or in your standard Git configuration. This tool is for developers, system administrators, or anyone who spends a lot of time working in a terminal and wants to share code or logs quickly. For example, if a developer needs to share an error log with a teammate, they can run a command to send the log directly to a private gist and get a link to share. It is also useful for sharing short scripts or configuration files without manually opening a web browser. You can configure it to open the newly created gist in your web browser automatically or to create all snippets as private by default. The project is built in Ruby and can be installed through common package managers like Homebrew or RubyGems. Notably, it offers a clever security feature where your GitHub token does not have to be stored in plain text. Instead, the tool can be configured to fetch the token from a secure storage system like the macOS Keychain by running a command to retrieve it on demand.
