example_file

Example File

Class helper for example files. Usually it's the alternative to environment variables (and .env files).

You can have git-controlled example files and git-ignored real files. For example, configuration, especially with sensitive data.

Installation

Add this line to your application's Gemfile:

gem 'example_file'

And then execute:

bundle install

Or install it yourself as:

gem install example_file

Usage

require 'example_file'

ExampleFile.new('some_file.example.conf').actualize_regular_file

For some_file.example.conf example file there is some_file.conf regular file.

Editor below is $EDITOR environment variable. You should set it to your preferred editor, console or GUI (console is more comfortable usually for such scenarios). Otherwise the whole program will be aborted with a message about this.

It'll act in these ways:

• If there is no regular file:
  • create it with content from example and open the editor.
• If there is example file with file modified time after regular file:
  • If there is no difference between their contents:
    • touch regular file for updating its modified time.
  • If there is a difference between their contents:
    • ask for a further action:
      • open the editor;
      • just update regular without changes;
      • replace regular file with a content from new example file;
      • or replace and then open the editor.
• If there is regular file with file modified time after example file:
  • do nothing.

You should add example files to git control:

git add some_file.example.conf

And ignore regular ones in .gitignore:

some_file.conf

Recursively it'd be like:

config/**/*
!config/**/*.example*
