This is a feature request.

apm is allow us to install package from github/gitlab/bitbucket but sync-settings doesn't support that.

Describe the solution you'd like

If the package is a git source, use the install source to construct apm arguments.

Here's an example of git package info:

{
  "name": "atom-tabs",
  "version": null,
  "apmInstallSource": {
    "type": "git",
    "source": "dangh/atom-tabs",
    "sha": "9264913b95450bb6ea4ad01338059376a47531ab"
  }
}

The command I use to install my package from github:

apm install dangh/atom-tabs

The command sync-settings constructed:

apm install atom-tabs

Describe alternatives you've considered

Maybe we can use atom API to install package instead of apm and skipping constructing the command. But I'm not familiar with atom API to say if it's possible to do so.

I don't think there is an Atom API to install the packages. The settings-view package just uses apm to install and update packages.

Just wondering if a minimal change to https://github.com/atom-community/sync-settings/blob/80c61f5f628960d2e1da3e9106fd9fc595145617/lib/utils/utils.js#L326-L331 would be enough...

Something like this :

if (atom.config.get('sync-settings.installLatestVersion')) {
  pkg.version = null
}
if (pkg.apmInstallSource) {
  pkg.name = pkg.apmInstallSource.source
  pkg.version = null
}

I'll test it and give results here.
