Its most visible purpose is title-casing prose, especially where English-only tools fail. ### Project history The README states that decasify was born from frustration with all-caps titles in Markdown sources and the lack of tooling for Turkish prose case conversion. The public repository was created in July 2023, and the changelog shows early CLI and Lua/Rust work followed by Python, JavaScript/WASM, SILE, Typst, Vim, and Neovim integrations. ### Adoption history decasify is unusual for a small case-conversion tool because it deliberately exposes the same functionality through many packaging ecosystems: Homebrew and Arch for the CLI, Cargo for Rust, LuaRocks, PyPI, npm, SILE, Typst Universe, and editor plugin managers. That spread is documented by the README installation and usage sections. ### How it is used CLI usage accepts arguments or standard input and defaults to English title case, with flags for locale and style guide. Library users call case-specific functions, while editor integrations expose a `:Decasify` command for transforming lines or ranges with configurable locale, style guide, and override words. ### Why package nerds care Package nerds care about decasify less as a huge utility and more as a clean example of one text-processing core shipped across several language and editor ecosystems. Its packaging matrix is the story: a Rust implementation serving CLI, Lua, Python, JavaScript, SILE, Typst, Vim, and Neovim users. ### Timeline - 2023: Repository created and 0.1.0 accepted standard input for the CLI. - 2024: Python, JavaScript/WASM, SILE, Neovim, and broader API work arrived through the 0.5-0.8 series. - 2025: Typst packaging and Spanish support appeared in later releases. - 2026: 0.11.3 added Neovim preview behavior, CLI help colors, binary-install tooling, and Lua 5.5 support. ### Related projects - decasify builds on and references the Rust titlecase crate for Gruber-style English title casing, while also consulting language-specific style sources such as Turkish Language Institute rules and Spanish style references. ### 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:** decasify - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - decasify: normalized package name match | nixpkgs package indexes: pkgs/by-name/de/decasify/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - pacman - decasify - 0.11.3-2: normalized package name match | Arch Linux sync databases: decasify from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | cast strings to title-case according to locale specific style guides including Turkish (CLI tool) | https://github.com/alerque/decasify ## 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. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [hck](https://www.automicvault.com/pkg/brew/hck/) - Shares av.db curated category or tags: cli, developer-tools, rust, text-processing. - [sd](https://www.automicvault.com/pkg/brew/sd/) - Shares av.db curated category or tags: cli, developer-tools, rust, text-processing. - [srgn](https://www.automicvault.com/pkg/brew/srgn/) - Shares av.db curated category or tags: cli, developer-tools, rust, text-processing. - [titlecase](https://www.automicvault.com/pkg/brew/titlecase/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, title-case. - [translate-toolkit](https://www.automicvault.com/pkg/brew/translate-toolkit/) - Shares av.db curated category or tags: cli, developer-tools, localization, python. - [tuc](https://www.automicvault.com/pkg/brew/tuc/) - Shares av.db curated category or tags: cli, developer-tools, rust, text-processing. - [align](https://www.automicvault.com/pkg/brew/align/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [bsdconv](https://www.automicvault.com/pkg/brew/bsdconv/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. ## Combined YAML source View the package source record on GitHub.
