## Project history and usage

`lolcrab` is a Rust terminal colorizer that describes itself as like `lolcat` but with OpenSimplex-style noise and more color. 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.
