Adding extra files to an already compiled binary using embed.FS

[Pablo Caballero]

Hi folks! I tried to do my homework and I think that the response is "No." I'm just looking for confirmation (maybe I missed something).

We are using embed.FS to create "bundles" with a LOT of extra files embedded into the executable. So far so good until we hit a use case where we should be adding an extra tiny file depending on some user interaction to already-built bundles. We:

* would love to have this extra file in the embedded FS (We want to avoid delivering it as an extra file)

* would love not to have to recompile

Is there any way to achieve that?

Thank you for any help you can provide!

What about merging two io.FS instance? A quick search positively surprises me, as there's https://pkg.go.dev/github.com/yalue/merged_fs for this already existing. So you could benefit from the build cache and yet add something later by merging/fusing multiple io.FS instances at runtime, from different packages. Deal...?

Thank you! I'll definitely take a look at that.

Best!
