Do you have CLI calls that you want to cache? Here you go!

Seems well-designed, but what’s the use case? I’m trying to think of them but my creativity is failing me.

I've always wanted to deal with cache invalidation in my terminal.

I wish this worked without prefixing the commands with "once". Especially if I ran a command with verbose output and afterwards decided I wanted to grep something from it. Terminals have the output in their scrollback buffer and maybe it's just a matter of writing an "output" command that lets me run:

    $ cmake ..
    $ output | grep "libssl version"

These kinds of tools are very useful. I have my own called memo (which is just a shell script: https://github.com/aktau/dotfiles/blob/master/bin/memo).

It was discussed in https://news.ycombinator.com/item?id=45670052 and others chimed in with their own (like bkt(1) and up(1)).

The main differences I see:

  - memo doesn't need to be built (its a shell script)
  - once keeps output cache in a running daemon. By contrast, memo stores content under /tmp with whatever the best compression available is (it prefers zstd). There's trade-offs in that. More pareto-optimal from the security front may be to have a sort of session key and to compress-then-encrypt files on disk.
