https://github.com/docker/buildx/compare/master...tonistiigi:buildx:history-inspect-format?expand=1 is my wip for adding format. Main difference is that there is a new struct for history inspection instead of raw HistoryRecord with other (random) values. That struct can be formatted and provides similar output to the default text (that also now comes from printing the struct).

I think this is preferred. If lgty you may finish that instead.

Yes looks good to me, I carry over your changes and keep you posted.

It doesn't return build name and error logs which is needed for GHA summary:

• https://github.com/docker/actions-toolkit/blob/d1d0bdb690cac771d025dcf2c42a74bb129c375c/src/github.ts#L290

I will make some changes to handle that

@tonistiigi Updated on top of your branch.

Steps counts were missing in out and also added build name and error logs that are needed for GHA summary. I didn't add error sources but I think we could. Should probably be base64 encoded?

Also missing materials and attachments. I guess we would want this in out.config?

Edit: added error sources

JSON should be usable as function as well like {{json .}}
