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. ### Timeline - Current README: Documents Homebrew installation. - Current README: Documents Cargo installation. - Current README: Documents `--after` and stdout/stderr pipe behavior. ### Related projects - Cargo is the Rust package channel documented by the README. - Homebrew is the system package channel documented by the README. - `tail -f` is the example producer used in the README. ### Sources - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** spacer - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - spacer: normalized package name match | nixpkgs package indexes: pkgs/by-name/sp/spacer/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - spacer - 0.5.0-r0: normalized package name match | Alpine Linux edge package indexes: spacer from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | CLI tool to insert spacers when command output stops | https://github.com/samwho/spacer - apk - spacer-doc - 0.5.0-r0: normalized package name match | Alpine Linux edge package indexes: spacer-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | CLI tool to insert spacers when command output stops (documentation) | https://github.com/samwho/spacer - dnf - spacer - 0.5.0-2.fc44: normalized package name match | Fedora Rawhide package metadata: spacer from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | CLI utility for adding spacers when command output stops | https://github.com/samwho/spacer ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [moor](https://www.automicvault.com/pkg/brew/moor/) - Shares av.db curated category or tags: cli, developer-tools, rust, terminal. - [ansifilter](https://www.automicvault.com/pkg/brew/ansifilter/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [colordiff](https://www.automicvault.com/pkg/brew/colordiff/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [colormake](https://www.automicvault.com/pkg/brew/colormake/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [et](https://www.automicvault.com/pkg/brew/et/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [faketty](https://www.automicvault.com/pkg/brew/faketty/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [grc](https://www.automicvault.com/pkg/brew/grc/) - Shares av.db curated category or tags: cli, command-output, developer-tools, logs, terminal. - [mle](https://www.automicvault.com/pkg/brew/mle/) - Shares av.db curated category or tags: cli, developer-tools, terminal. - [fblog](https://www.automicvault.com/pkg/brew/fblog/) - Both packages touch the same language runtime or ecosystem.
