## What it is
spacer is a small Rust CLI utility that inserts visual spacers into piped command output after a configurable period of inactivity. It is designed for workflows like tailing logs, making it easy to see where one burst of output ends and the next begins.

## Use cases
- insert blank separators in log output when tailing files
- visually separate bursts of command output in the terminal
- replace habitually pressing enter to mark log boundaries
- pipe any command through a filter that adds spacers on idle output
- monitor long-running processes with clearer output separation

## When to choose
- you frequently tail logs and want automatic visual separation of output
- you want a tiny, fast Unix-style pipe filter for terminal readability
- you want a simple installable Rust CLI with configurable idle timeout

## When to avoid
- you need to monitor STDERR, since spacer only watches STDOUT
- you need structured log processing or filtering rather than visual spacing
- you need a GUI or interactive log viewer
