aperçu
Ur/Web programming language
historique
Ur/Web is a domain-specific, statically typed functional programming language and compiler for database-backed web applications. The official site presents Ur as an ML/Haskell-like pure, strict, statically typed language with row-type metaprogramming, and Ur/Web as Ur plus web-specific parsing, optimization, and a standard library for dynamic SQL-backed applications.
Adam Chlipala's 2010 PLDI paper introduced Ur as a language for statically typed metaprogramming with type-level record computation and described Ur/Web as a special standard library for modern web applications. The official resources page lists additional 2010 talks, a 2010 OSDI paper on security policies, and later Ur/Web research papers.
The 2015 POPL paper framed Ur/Web as a simpler model for modern web programming: one language compiled to the necessary web-standard languages, with modular encapsulation of web state and a concurrency model based on transactions and cooperative preemption. The same period also produced an ICFP 2015 compiler paper describing Ur/Web compilation to efficient native code without garbage collection.
The current GitHub README and official site emphasize type-level guarantees uncommon in mainstream web frameworks: well-typed programs should avoid code injection, invalid HTML, dead internal links, form-handler mismatches, invalid SQL queries, and marshaling mistakes between browser, server, and database.
The official site lists several production applications, including BazQux Reader, Bitcoin Merge Mining Pool, Ecosrv, Extensibl, and Oilprice, along with student projects and blog posts from 2010 onward. It also lists package/container availability in Arch AUR, Debian, Docker, Homebrew, Milis Linux, Nix, OpenBSD experimental ports, and Ubuntu, while this batch's input confirms Homebrew and Nix package-manager records.
A typical package-manager user installs the compiler as urweb, writes .ur, .urs, and .urp project files, and invokes the urweb executable to compile applications. The GitHub README shows compiling and running a bundled hello demo, while the official resources page directs users to a tutorial, reference manual, demos, FAQ, mailing list, and GitHub issues.
Ur/Web is package-nerd significant because it is not just another library: it is a research language, compiler, runtime model, and web framework packaged as a Unix-style compiler tool. Its availability in Homebrew, Nix, Debian, Ubuntu, and other systems makes an academic language experiment installable through ordinary package workflows.
It also illustrates why package metadata can matter for niche languages. A formula or derivation gives users a reproducible compiler and dependencies, which is crucial for trying a language whose value comes from whole-program guarantees and compiler behavior rather than a single library API.
