Enhance Your Code Sharing with carbon-now-cli: Discover Its Powerful APIs

carbon-now-cli is a powerful command-line tool that allows you to create beautiful code snippets right from your terminal. This tool integrates seamlessly with Carbon, a web app for creating and sharing code images. In this post, we will introduce carbon-now-cli and dive into its versatile API functions with practical code snippets and an application example.

Getting Started with carbon-now-cli

To install carbon-now-cli, run:

npm install -g carbon-now-cli

Basic Usage

Generating a code snippet image from a file is straightforward:

carbon-now myCodeFile.js

Customizing Your Snippet

You can customize the appearance of your snippet with various options:

Choosing a specific theme:

carbon-now myCodeFile.js --theme=night-owl

Specifying a background color:

carbon-now myCodeFile.js --background-color=#abcdef

Changing the font size:

carbon-now myCodeFile.js --font-size=18px

Batch Processing

Generate snippets for multiple files in one go:

carbon-now *.js

Applications Integration

Integrate carbon-now-cli into a build process or a git hook for consistent and beautiful code sharing:

Example with a Node.js application:

 // File: generateSnippets.js
const { exec } = require('child_process');
const files = ['file1.js', 'file2.js', 'file3.js']; files.forEach(file => {
  exec(`carbon-now ${file}`, (err, stdout, stderr) => {
    if (err) {
      console.error(`Error generating snippet for ${file}:`, stderr);
    } else {
      console.log(`Snippet for ${file} created successfully:\n`, stdout);
    }
  });
}); 

Real-World Example

Here’s a practical example showing how to integrate carbon-now-cli into a continuous integration (CI) process using GitHub Actions:

 name: Generate Code Snippets
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
    - name: Install Node.js
      uses: actions/setup-node@v2
      with:
        node-version: '14'
    - name: Install carbon-now-cli
      run: npm install -g carbon-now-cli
    - name: Generate Snippets
      run: carbon-now src/**/*.js --output snippets/
    - name: Commit and Push Snippets
      run: |
        git config --global user.name 'github-actions'
        git config --global user.email 'github-actions@users.noreply.github.com'
        git add snippets/
        git commit -m 'Add code snippets [skip ci]'
        git push

In this example, every time you push changes to your repository, GitHub Actions will generate code snippets for JavaScript files in the src directory and store them in the snippets directory.

By leveraging carbon-now-cli, you can ensure that your code snippets are consistently styled and readily available for review or sharing.
