How to use standard input/output

By default, Whiskers:

1. Takes in a template via standard input.
2. Renders the template.
3. Outputs the template to standard output.

Let’s walk through those steps to get a better understanding:

1. Execute the following command in your terminal:

   $ whiskers -

2. The terminal is now waiting for standard input, let’s get the value of Catppuccin Mocha Red as a hex code by typing the highlighted text:

   $ whiskers -
   Catppuccin Mocha Red - {{flavors.mocha.colors.red.hex}}

3. Now press Ctrl-D to send an EOF signal, and allow Whiskers to render and output. Your terminal should now look like this:

   $ whiskers -
   Catppuccin Mocha Red - {{flavors.mocha.colors.red.hex}}
   Catppuccin Mocha Red - f38ba8

4. Well done! You’ve just used Whiskers via standard input/output.
