history
Project history and usage
spacer is a small Rust command-line utility that inserts separator lines into a stream when command output pauses. It is aimed at terminal users who follow logs or long-running command output and want visible boundaries between bursts.
Project history
The official README presents spacer as a simple CLI tool for inserting spacers when command output stops. It is distributed as a Rust crate and as a Homebrew package according to the README, with additional package availability recorded in the input facts.
Adoption history
spacer's official adoption story is modest but package-manager-shaped: the README names Homebrew and Cargo installation, while the input package facts also list apk, dnf, and Nix. That makes it a small utility available through both language and OS package ecosystems.
How it is used
The default behavior is to emit a spacer after one second without output. Users can change the interval with `--after`, including floating-point seconds, and can pipe both stdout and stderr with shell syntax such as `|&` when a command writes mostly to stderr.
A typical use is `tail -f some.log | spacer --after 5`, which turns a continuous log stream into visually separated bursts without changing the producing command.
Why package nerds care
spacer matters to package nerds as a very small example of packaging terminal ergonomics. It does not replace logging tools; it packages one habit, pressing Enter while tailing logs, into a reusable filter.
Its availability through Cargo and system package managers makes it easy to add to dotfiles, shell pipelines, and development machines without vendoring a script.
