Menu variable for commit subject

[corytodd]

I’m trying to add a custom commit menu that can copy a oneline log from a commit. My first idea was to use the git command with argv but then I thought there might be an existing variable for $commit_subject. I don’t see one in the Default package.

Does anyone know of such a variable?

Here is what I’d like to have

[
    {
	"caption" : "Log Oneline",
	"command" : "copy_to_clipboard", 
	"args" : {
	    "text": "($short_commit) $commit_subject"
	},
    }
]
