Vue-cli: Add '--force' flag to 'vue init' command

[codetheorist]

Problem:

When testing templates, it's a frequent cause of headaches when testing.

Currently in the template test.sh scripts, they use the yes command piped to the vue init, which doesn't work.

Solution

To workaround this, we could add a --force flag that will send a new line character to each inquirer prompt.

We could use the mock-stdin package for sending the input to the prompt.

There is a PR coming shortly, fully tested with the Vue Webpack template using both the --force and the -f flag.

Imho we should rather provide a way to skip the inquirer prompt completely and load some predefined answers from some .json file or something. Kind of what I implemented in https://github.com/vuejs-templates/webpack/pull/1218

The new version in next branch supports that:

$ vue create --help

  Usage: create [options] <app-name>

  create a new project powered by vue-cli-service


  Options:

    -p, --preset <presetName>       Skip prompts and use saved preset
    -d, --default                   Skip prompts and use default preset
    -i, --inlinePreset <json>       Skip prompts and use inline JSON string as preset
    -r, --registry <url>            Use specified NPM registry when installing dependencies
    -m, --packageManager <command>  Use specified NPM client when installing dependencies
    -f, --force                     Overwrite target directory if it exists
    -h, --help                      output usage information

@yyx990803 or @LinusBorg But i can't use vue create template-url ? So what i'm going to do if i need to init template from repo and skip prompts?

The old 2.x functionality can be re-added with a plugin:

We won't add any new features to it, though.
