Bkt
Jul 20, 2023
Subprocess caching utility
bkt pronounced bucket is a subprocess caching utility written in Rust, inspired by bash-cache. Wrapping expensive process invocations with bkt allows callers to reuse recent invocations without complicating their application logic. This can be useful in shell prompts, interactive applications such as fzf, and long-running programs that poll other processes.
When bkt is passed a command it hasn’t seen before or recently it executes the command synchronously and caches its stdout, stderr, and exit code. Calling bkt again with the same command reads the data from the cache and outputs it as if the command had been run again.
