Workflow for creating project and pushing existing code

[multimeric]

Issue Description

I'm after a workflow when I already have some AppsScript code from an external source (e.g. from GitHub), and I want to create a new Google project and push the code there.

I had hoped I could do something like this:

clasp create --empty # Note, this flag doesn't exist
git clone SomeAppsScriptRepo
clasp push

Currently the only way to do this, as far as I can tell is:

clasp create --type TYPE --title TITLE
rm appsscript.json # We don't need this
git clone SomeAppsScriptRepo
clasp push

Specifications

• Node version (node -v): v11.15.0
• Version (clasp -v): 2.3.0
• OS (Mac/Linux/Windows): Ubuntu 18.04

@multimeric What do you think of the solution proposed in #991?

[multimeric]

So after this PR, the workflow would be:

git clone SomeAppsScriptRepo
clasp remote create <name>

Is that right? Because that would be better than even what I suggested.

Yep, glad to hear you like the proposal! Could you also voice your support in #991 for visibility? Thanks!
