Drafts Directory: Diff Versions

Action

Posted by agiletortoise, Last update 11 months ago

Note: The Mergely library on which this action is based is not optimized for use on smaller screens. As such, this action is best used on Mac - although it can be used on iPad, or even iPhone, it is a less than optimal experience.

Open a diffing tool to compare and merge values from the current draft’s version history.

Once opened, you can select from the past draft versions in the drop-down menu. Changes will be displayed and can be merged between the versions.

Once you are satisfied with the changes, you can save either version as the current version of the draft - or discard changes.

This action utilizes the Mergely diffing tool.

Steps

script

// gathers a list of past versions of the draft currently loaded in the editor

let f = () => {
	let versions = draft.versions

	if (versions.length == 0) {
		alert("The current draft has no past versions in the version history. This action requires a version history to show differences.")
		return false
	}

	let sources = [
		{
			"name": "Current",
			"value": draft.content
		}
	]
	for (let v of versions) {
		sources.push({
			"name": `V: ${strftime(v.createdAt, "%Y-%m-%d %H:%M")}, ${v.content.length} char`,
			"value": v.content
		})
	}

	draft.setTemplateTag("sources", JSON.stringify(sources))
	return true
}

if (!f()) {
	context.cancel()
}
