yml-include v1.0.5

YML-INCLUDE

The yml-include library is a simple and efficient solution for developers working with YAML files. It allows easy management of YAML file inclusions, which simplifies configuration management and reuse of code fragments.

Getting started

You can easily install yml-include using this command

npm install yml-include -D

Use

Once installed yml-include is used with this single command

npx yml-include <entry_file.yml> <dist_file.yml>

This will start a build of your YAML files

You can add the --watch parameter to make yml-include rebuild when saving an included file

npx yml-include <entry_file.yml> <dist_file.yml> --watch

Or you can defined a script in your package.json to run npm run <your_script_name>

  "scripts":{
    "build-yml": "yml-include <entry_file.yml> <dist_file.yml>"
    "watch-yml": "yml-include <entry_file.yml> <dist_file.yml> --watch"
  }

Syntaxes

There are two syntaxes specific to the yml-include library #@include <relative_path> & #@slot:<slot_name> <value>

@include

Syntax @include <relative_path>

The use of @include allows to include the content of another YAML file, this one needs a relative path to the desired .yml file, there is no need to specify the .yml extension

Example

./entry-docker-compose.yml

services:
  database:
    image: mysql
  #@include ./services/nginx

./services/nginx.yml

web:
  image: nginx

out-docker-compose.yml

services:
  database:
    image: mysql
  web:
    image: nginx

@slot

Syntax @slot:slot_name <value>

Combined with an @include the @slot allows to interpolate a value in the included file, let's use the same example as before

example

./entry-docker-compose.yml

services:
  database:
    image: mysql
  #@include ./services/nginx
  #@slot:image_version nginx:latest

./services/nginx.yml

web:
  image: #@slot:image_version

out-docker-compose.yml

services:
  database:
    image: mysql
  web:
    image: nginx:latest

This allows you to create some kind of reusable YAML component.

Features

Error Management

In case of error on imported files, the script shows you the line and the file concerned by the erroneous include

File Caching

The purpose of this script is to simplify the writing of large YAML files by allowing multiple use of the same include from the same or another file. The script caches all open files to preserve access to your hard disk.

In the futur

• Prevent from circular include cause infinit loop
• Add warning about syntax close to basic yml-include syntax (#@)
