It reads files or standard input and colorizes terminal output with gradients, animation, and configurable noise parameters. ### Project history The official README says `lolcrab` is a fork of `lcat-rs`, placing it in the family of playful terminal color filters descended from `lolcat`. The GitHub repository was created in 2021, and GitHub releases show the public 0.2 through 0.4 series continuing into 2025. ### Adoption history `lolcrab` is distributed as a Rust crate and through package-manager channels. Its README points users to precompiled Linux, macOS, and Windows binaries on GitHub releases, documents `cargo install lolcrab`, and includes a Repology packaging badge; the batch input records Homebrew packaging. ### How it is used The CLI accepts files or standard input, defaults to a rainbow gradient, and exposes options for gradient selection, custom CSS gradients, noise scale, seed, inverted/background coloring, animation, and version/help output. The README also documents library use from Rust through `Lolcrab::new` and `colorize_str`. ### Why package nerds care `lolcrab` is small but package-catalog-friendly: it is a cross-platform terminal toy, a Rust binary crate, and a modern variant of the long-running `lolcat` terminal-filter idea. It is useful when testing packaging of Rust CLI tools with release binaries and Cargo installation paths. ### Timeline - 2021: `mazznoer/lolcrab` repository created on GitHub. - 2022: v0.2.0 release published on GitHub. - 2024: v0.4.0 release published on GitHub. - 2025: v0.4.1 release published on GitHub. ### Related projects - `lcat-rs` is the upstream project named in the README as the fork source. - `lolcat` is the older terminal-colorizer concept that `lolcrab` explicitly references. ### Sources - - - - source_facts.package-manager-url ## 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:** lolcrab - **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. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [lolcat](https://www.automicvault.com/pkg/brew/lolcat/) - Shares av.db curated category or tags: cli, color, system, terminal, terminal-utilities. - [hr](https://www.automicvault.com/pkg/brew/hr/) - Shares av.db curated category or tags: cli, system, terminal, terminal-utilities. - [bottom](https://www.automicvault.com/pkg/brew/bottom/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [eza](https://www.automicvault.com/pkg/brew/eza/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [hyfetch](https://www.automicvault.com/pkg/brew/hyfetch/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [kbt](https://www.automicvault.com/pkg/brew/kbt/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [lsd](https://www.automicvault.com/pkg/brew/lsd/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [nsh](https://www.automicvault.com/pkg/brew/nsh/) - Shares av.db curated category or tags: cli, rust, system, terminal. ## Combined YAML source View the package source record on GitHub.
