Today I forked oik-block to create oik-blocks. The oik-blocks plugin will be the version on WordPress.org. oik-block will contain the Gutenberg compatibility logic only.
The only block in the first version is Countdown, a countdown timer.
Sorry but this block is not working at present.
Testing prototype blocks from oik-block v0.0.0-alpha-20181118 with Gutenberg v4.4.0 on [wp v].
In 4855 the oik shortcode buttons don’t work for the Classic block.
With oik 3.2.5 the shortcode buttons may not work at all, unless the theme or another plugin enqueues thickbox jQuery and CSS using add_thickbox.
Once that’s fixed the actual insertion of the shortcode appears to be random. The behaviour is a similar problem to #10509, which is related to the Add media button, a core component.
The fix to oik issue #100 has also resolved the problem of the buttons not working at all on my iPad.
Gutenberg v4.4.0 was released on 15th November. The list of changes is as long as your arm.
