history

Project history and usage

decasify is a locale-aware string case conversion project packaged as a CLI, Rust crate, Lua rock, Python module, JavaScript/WASM module, editor plugin, SILE package, and Typst package. 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.
