grunt-init template conditional copy files

问题

I've just started using grunt-init. I have everything working. And I was wondering if there is a way to do conditional copy root files based on prompts which based on answers to previous prompts.

You can make use of the rename.json file via the docs.

The prop should be the path to the file you want to copy/not copy, and the value can be a template string with a conditional. For example, let's say you had two different main.js files, one empty and one with code you tend to re-use:

{
  "app/js/main-empty.js": "{% if (empty) { %}app/js/main.js{% } %}",
  "app/js/main-skeleton.js": "{% if (!empty) { %}app/js/main.js{% } %}"
}

The destpath checks the value of the props.empty variable from your template.js file, copies and renames correctly.

Here is a link to a gist showing the template.js and rename.js for that example.
