CAM CLI

This is the cam cli. It's here because we are dumb and forget stuff.

Usage

1. build the monorepo project with: rushx build
2. run npm link from this projects directory
3. type cam into your shell

Adding New Commands

After any updates, you must re run rush build and you must navigate to this projects directory and run npm link.

IMPORTANT NOTE: This is a rush repo, so using npm link can be screwy. If you get errors, run rush unlink and try again. Note that you will not be able to run npm link inside of the "scripts." That will cause issues with Rush.

Basic Example

Step 1 - Create a function that does shit in any file in src/helpers/whatever-you-want.ts

import 'zx' // the $ syntax won't work without this
const printShitToConsole = async (shit: string) => {
  await $`echo "${shit}"`
}

Step 2 - Add a function that returns a new command with Commander to src/commands.ts

import { Command } from 'commander'
import { printShitToConsole } from './helpers/printShitToConsole'
const doShitCommand = () =>
  new Command('printShit') // "cam printShit" is the text you would type to run this command
    .alias('ps') // you could use "cam ps" instead of "cam printShit"
    .addHelpText('after', "You can't be helped") // if you ran "cam ps --help" then this text would be displayed after
    .description('prints stupid shit to console') // If you ran "cam" without arguments, this text would show up next to the command
    .action(() => {
      // This is the stuff that happens when the command is run
      printShitToConsole('shit')
    })

Step 3 - Add command to object inside of src/cli.ts

src / cli.js

const UNIMPAIRED_CLI = new Command('cam')
  // ... all commands are in this chain
  .addCommand(doShitCommand()) // This is the line you will add to this file

How to Add A Select Field

We use the inquirer package to do this

import inquirer from 'inquirer'
const askForDisability = () => {
  const prompt = inquirer.prompt(
    // First Question
    [
      name: 'firstQuestion',
      message: 'Do you want to quit life?',
      type: 'confirm',
      choices: ['yes', 'no'],
    ]
    // Second Question
    [
      name: 'secondQuestion',
      message: 'Which character traits match you?',
      type: 'checkbox', // they will select check the options they want
      choices: ['idiot', 'freak', 'sexual deviant', 'mindless murderer']
    ]
  ).then((prompt) => {
    // prompt is an object whose 'keys' equal the 'name' property in the prompt
    // the value is equal to the 'choices' that the user decided
    const firstQuestionData = prompt.firstQuestion
    const secondQuestionData = prompt.secondQuestion
    console.log('Go fuck yourself, ', secondQuestionData.join(' '))
  })
}

NOTES

File Structure

/src
  cli.ts // This is the file we run/export to use the command line
  commands.ts // This file contains all the commands that we use
  /helpers
    // ... any code that is imported into the above files
    // ... there really shouldn't be that much shit here.  Keep it simple.

Important Packages

• commander: creates the CLI
• inquirer: allows the cli to prompt a user for multiple options
• zx: allows us to run bash scripts in our TS code
