View Source Creating Templates

Rules:

• the OTP application name of a template must be :my_app.
• the base module name of a template must be MyApp.
• the environment variables used in a template must be prefixed with MY_APP.
• = random_string(length) = should be used as the placeholder of random string. For example:
  • = random_string(20) =, which generates 20-char random string.
  • ======== random_string(20) ========, which generates 20-char random string.

Why use "my_app" and similar placeholders? Because combo_new generates projects from templates using string replacement (this method is primitive but straightforward and quick), and to prevent conflicts with strings users might actually use, I subjectively chose my_app, which is short, easily recognizable, and no one uses it in serious code.
