The README positions `counts` as an improved alternative to the Unix `sort | uniq -c` pipeline for profiling data gathered from logging print statements. The project reached a 1.0.0 release in 2023 and continued with later 1.0.x releases. ### Adoption history Official installation is through `cargo install counts`, with Homebrew adding a binary-package route for users who prefer system package managers. ### How it is used The tool is commonly used by inserting temporary logging into a program, piping or saving those logs, and then using `counts` to aggregate hot paths, loop counts, allocation sizes, or other domain-specific measurements. The README includes a Firefox heap allocator instrumentation example, showing `counts` applied to millions of log lines and weighted byte totals. ### Why package nerds care For package nerds, `counts` is interesting because it deliberately packages a Unix-pipeline-shaped workflow as a fast single-purpose Rust binary: no daemon, no config, and no profiler integration required. ### Timeline - 2018: Public GitHub repository created. - 2020: 0.1.2 release published. - 2023: 1.0.0 release published. - 2026: 1.0.7 release published. ### Related projects - Rust - cargo install - sort - uniq ### Sources - - - ## 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:** counts - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 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. - [cargo-flamegraph](https://www.automicvault.com/pkg/brew/cargo-flamegraph/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling, rust. - [cargo-bloat](https://www.automicvault.com/pkg/brew/cargo-bloat/) - Shares av.db curated category or tags: cli, developer-tools, profiling, rust. - [cargo-instruments](https://www.automicvault.com/pkg/brew/cargo-instruments/) - Shares av.db curated category or tags: cli, developer-tools, profiling, rust. - [flamebearer](https://www.automicvault.com/pkg/brew/flamebearer/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [flamegraph](https://www.automicvault.com/pkg/brew/flamegraph/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [gprof2dot](https://www.automicvault.com/pkg/brew/gprof2dot/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [memray](https://www.automicvault.com/pkg/brew/memray/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [py-spy](https://www.automicvault.com/pkg/brew/py-spy/) - Shares av.db curated category or tags: cli, developer-tools, performance, profiling. - [samply](https://www.automicvault.com/pkg/brew/samply/) - Both packages touch the same language runtime or ecosystem.
