Is something like carapace expand possible?

[dwt]

I would often like a tool that allows me to expand short option forms that I copied from some script or Webseite to their long option form.

e.g. carapace expand curl -sSf -L https://install.lix.systems/lix to
Do you want to run curl --fail --show-error --silent --location https://install.lix.systems/lix ?

This would be especially handy, as I (and most other people) do not have the short options memorized, and the long options are much easier to remember / read / understand.

As I don't understand much about carapace yet, does the data it provides / has actually allow to implement something like this?

Yes and no.

For commands that are fully described in carapace without dynamic aspects, yes.
But not all are so simple and for example embed other commands.

I've got some plans for something like this, but that will take a while.

This would also be a spectacular feature for shell scripts as a language server. That way whenever I write them, this could lint them to use long options in written scripts.
