Add GistPress block for Gutenberg

[GaryJones]

The new Gutenberg editor seems ripe for us to consider adding a GistPress Embed block, with all of the current shortcode attributes mapped to block attributes.

Expected Behavior

Quick couple of mockups, as example:

Current Behavior

None

Possible Solution

Gists inserted with GistPress naturally fit into the block system that Gutenberg uses.

Steps to Produce

1. Decide on whether the neutral view (after first inserting a block) should ask for the Gist ID / URL (like the Embed block asks for a URL).
2. Register block, attributes.
3. Display attributes in settings panel, with any descriptions as needed.
4. Try and get a basic preview working.
5. Adapt preview to represent what the block attributes are set as.
6. Support width / alignment attributes like image blocks do?
7. Don't break when used on a site that doesn't use Gutenberg Editor.

Here's a plugin of mine that adds Gist ability to the Gutenberg Editor for reference: Gistr WP Plugin

Tried both the Gistr ( embed block) & GistPress ( html block) . Both impressive, with the former having the edge through ease of use. Maybe you should combine code bases 😉
