Repeat button for Play

[maartenbreddels]

Some animation may benefit from having a repeat option, for instance here:
https://www.astro.rug.nl/~breddels/test/wave/
I'm not sure if a repeat button should always be shown, but I don't think it will hurt.

[jasongrout]

A reverse button and maybe a speed of play button would also be interesting.

[maartenbreddels]

Would be nice if these could be optional, to not clutter the gui.

[SylvainCorlay]

@maartenbreddels PR welcome!

[maartenbreddels]

Ok, but dev-install.sh often fails for me, a new clean clone might work again, I may try.

[SylvainCorlay]

I don't actually use dev_install.sh!

[maartenbreddels]

I always get the same, I start from a clean fork, everythings works. When I run npm run update from nbwidgetsextension a 2nd time, it fails running npm install file:../jupyter-js-widgets

air2 ~/src/ipywidgets/widgetsnbextension (master ✗)$ npm install file:../jupyter-js-widgets                                                                         ipywidgets-dev

Any idea?

[SylvainCorlay]

Did you run npm install in jupyter-js-widgets?

[maartenbreddels]

Yes, I get the same error. I even added "underscore": "^1.8.3" as devDependency, but i guess devDependencies includes dependencies

[maartenbreddels]

I removed the jupyter-js-widgets/node_modules and after that it ran fine!

[dsblank]

A step button would be handy for play. I had to add a button (haven't made it look the same though):

[SylvainCorlay]

@dsblank great idea.

What is this screenshot?

[dsblank]

@SylvainCorlay Thanks... it would be useful for this project. This is a robot simulator written in pure Python. Here is a notebook in the Jyro repo:

https://github.com/Calysto/jyro/blob/master/docs/Visual%20Simulator.ipynb

Requires Jyro and Calysto (SVG graphics) libraries from git.

The library is designed for Deep Learning and Robots. I'm working on a book on this topic. Will come with a set of notebooks for readers to run their own experiments.

It seems like this issue is closed now, yes? I see support for 🔁 repeat in Play in version 7.0.0, per the merged PR above. As for the step button, it looks like I can use my left and right arrow keys to increment by one step, albeit not in a GUI button.
