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
