Baptz

CLI utility that helps construct names adhering to naming conventions.

Installation

npm install -g baptz

You will also need to install a naming convention configuration by doing baptz add and supplying a URL to the configuration. As such, the naming convention can be hosted externally (e.g. in a git repo).

Usage

$ baptz --help
 
  Usage: baptz [options] [command]
 
 
  Options:
 
    -V, --version  output the version number
    -h, --help     output usage information
 
 
  Commands:
 
    run         construct a name based on the current active naming 
                convention - default if no command specified
    add         add a new naming convention
    update      reload naming convention(s)
    nc          set naming convention to use (if multiple available)
    help [cmd]  display help for [cmd]
 
  Active naming convention: my-aws-naming-convention

Config

Baptz configuration is stored at <USER_HOME>/.config/configstore/baptz.json

In addition to the namingConventions config, the following config props are available:

Name	Description
active	The name of the active naming convention. Can be set in the CLI using the baptz nc command.
autoUpdate	Boolean denoting whether or not auto updating is turned on. Defaults to true.
autoUpdateAfterMinutes	The number of minutes between each update check. Defaults to 120
lastUpdated	ISO date for when the last update was run.

Naming conventions

Naming conventions are json configuration files consisting of templates and questions. Examples say more than 1000 words:

{
  "name": "my-aws-naming-convention",
  "resources": [
    {
      "name": "EC2::Subnet",
      "template": "sn-{regionCode}{az}-{vpcName}"
    },
    {
      "name": "EC2::VPC",
      "template": "vpc-{regionCode}-{descriptiveName}"
    },
    {
      "name": "S3::Bucket",
      "template": "hf-s3-{regionCode}-{envCode}-{descriptiveName}-{f:randomDigits(12)}"
    }
  ],
  "questions": [
    {
      "name": "regionCode",
      "message": "Region?",
      "type": "list",
      "choices": [
        {
          "name": "eu-west-1 (Ireland)",
          "value": "ew1",
          "short": "ew1"
        },
        {
          "name": "eu-west-2 (London)",
          "value": "ew2",
          "short": "ew2"
        },
        {
          "name": "eu-central-1 (Frankfurt)",
          "value": "ec1",
          "short": "ec1"
        }
      ],
      "default": "ew1"
    },
    {
      "name": "availabilityZone",
      "message": "Availability Zone?",
      "type": "list",
      "choices": [
        "a",
        "b",
        "c"
      ]
    },
    {
      "name": "envCode",
      "message": "Environment?",
      "type": "list",
      "choices": [
        {
          "name": "Production",
          "value": "p"
        },
        {
          "name": "Staging",
          "value": "s"
        },
        {
          "name": "Development",
          "value": "d"
        }
      ]
    },
    {
      "name": "descriptiveName",
      "message": "Descriptive name:",
      "type": "input"
    }
  ]
}

Resources

A naming convention resource is described by a name and a template. Templates contain placeholders (enclosed by braces, {}). Placeholders point at questions (which are defined in the questions array of the config file). When running baptz for a given template, the placeholders will be populated by the answers to the questions associated with the placeholder.

If a placeholder references a question that is not defined in the questions array, an "input type" question will be constructed automatically based on the name.

Questions

Defines questions according to https://www.npmjs.com/package/inquirer#questions

Generator functions

Placeholders can reference "generator functions". These are prefixed with f:, such as f:randomDigits(12). When running baptz, these placeholders will be subsituted with the result of such a generator function.

The following generator functions are available:

Generator	Params	Example	Description
randomDigits	size (int)	f:randomDigits(12)	Returns a random string of digits with specified length
randomChars	size (int)	f:randomChars(4)	Returns a random string of letters with specified length
randomCharsUpperCase	size (int)	f:randomCharsUpperCase(4)	Returns an upper-cased random string of letters with specified length
randomAlphanum	size (int)	f:randomAlphanum(4)	Returns a random string of alphanumeric characters with specified length
randomAlphanumUpperCase	size (int)	f:randomAlphanumUpperCase(4)	Returns an upper-cased random string of alphanumeric characters with specified length

Filter functions

Placeholders can reference "filter functions". These are prefixed with <functionName>:, such as pc:myQuestion. When running baptz, these placeholders will be substituted with the filtered output of a user's answer to the question. E.g. if the user answers "my answer", then "MyAnswer" will be the result.

The following filter functions are available:

Filter	Example	Description
uc	uc:myQuestion	UPPERCASE
lc	lc:myQuestion	lowercase
pc	pc:myQuestion	PascalCase
cc	cc:myQuestion	camelCase
sc	cc:myQuestion	snake_case
kc	cc:myQuestion	kebab-case

Special placeholders/questions

Placeholder	Description
shortname	The resource shortname value from the resource JSON (config)
resourceRef	Prompts to select another resource, and outputs its shortname. Can be used if you need your resource to reference another resource.

Support (OS Terminals)

Baptz is based on Inquirer.js, thus you should expect mostly good support for the CLIs below:

• Mac OS:
  • Terminal.app
  • iTerm
• Windows:
  • ConEmu
  • cmd.exe
  • Powershell
  • Cygwin
• Linux (Ubuntu, openSUSE, Arch Linux, etc):
  • gnome-terminal (Terminal GNOME)
  • konsole
