Load a JSON from local storage

[pillo79]

Describe the request

I would like to be able to load a package JSON file (possibily with its matching signature!) from a local path and not an URL. This would be really helpful to CI jobs for testing JSON files before public release. In this context, it would also be helpful to have the cli load only the specified file, ignoring any default index.

Describe the current behavior

--additional-urls can be used to fetch data from extra JSONs in most cli commands. However, arguments which are not URLs have no effect. Also, there is no way to avoid loading the default index contents AFAICS.

A current dirty "workaround" is to initialize the cli, then replace ~/.arduino15/package_index.json with the desidered file contents.

Hi @pillo79.

I would like to be able to load a package JSON file (possibily with its matching signature!) from a local path and not an URL.

You can do this by using the file scheme in the URL.

Also, there is no way to avoid loading the default index contents AFAICS.

I concur. You are welcome to open a dedicated feature request issue if you think this would be useful.
