What type of change do you want to see?

New feature

Overview

Introduce a theme duplicate command in the cli, so developers can duplicate a theme in the library.

Motivation

Pushing an entire new theme via cli takes considerably longer than duplicating a pre existing theme - especially in cases where the merchant has lots of assets.

In my workflow, I never overwrite the live theme directly. Instead, when deploying, I create a new theme and allow the merchant to review it before making the decision to publish.

With the duplicate command, I could simply duplicate the live theme and push any changes to it - in that case only the files that have changed will be overwritten.

This is a clone of the (closed) issue here:
#2000

Just to reiterate, this would be very useful for CI/CD workflows.

This issue is still relevant. We actually have another reason for it - to keep all theme translations. We tried the long way to first download current published theme and then publish it as a new theme. In that case theme translations get removed and lost. But if we use theme duplicate, all theme translations are kept in the duplicated theme. CLI command that would behave the same would actually enable us to use CI/CD the way we need, because currently we need to work directly on the published theme.

We are just starting our shopify implementation and being able to duplicate a theme programmatically seems like a critical requirement for CI/CD and general deployment automation.

I would also love for this command to be available with ability to rename the theme at the same time.

A use case could be, making a backup before deploying changes via CI/CD.

Something like ⤵︎

shopify theme duplicate --environment production --rename-to "📦 Pre Deployment Backup"

Bonus points:

If it could return a theme id in some way, so we can use automate something like ⤵︎

• duplicate a theme -> outputs new theme id
• Use theme id to run test suite against it
• Use theme id to delete it

Just a thought 💡

This should absolutely be a feature of the CLI.
As @mgrbec noted, if it ever does get implemented it's imperative that translations are copied over, the same way they are when using the duplicate button in Shopify admin (related issue: #4486)

Agreed, setting up our CI/CD pipelines right now and surprised this is not a feature of the CLI.

Another vote for this.
