|
Ur is a programming language in the tradition of ML and Haskell, but
|
|
featuring a significantly richer type system. Ur is functional, pure,
|
|
statically-typed, and strict. Ur supports a powerful kind of
|
|
metaprogramming based on row types.
|
|
|
|
Ur/Web is Ur plus a special standard library and associated rules for
|
|
parsing and optimization. Ur/Web supports construction of dynamic web
|
|
applications backed by SQL databases. The signature of the standard
|
|
library is such that well-typed Ur/Web programs "don't go wrong" in a
|
|
very broad sense. Not only do they not crash during particular page
|
|
generations, but they also may not:
|
|
|
|
* Suffer from any kinds of code-injection attacks
|
|
* Return invalid HTML
|
|
* Contain dead intra-application links
|
|
* Have mismatches between HTML forms and the fields expected by their handlers
|
|
* Include client-side code that makes incorrect assumptions about the "AJAX"-style services that the remote web server provides
|
|
* Attempt invalid SQL queries
|
|
* Use improper marshaling or unmarshaling in communication with SQL databases or between browsers and web servers
|
|
|
|
This type safety is just the foundation of the Ur/Web methodology. It is
|
|
also possible to use metaprogramming to build significant application pieces
|
|
by analysis of type structure. For instance, the demo includes an ML-style
|
|
functor for building an admin interface for an arbitrary SQL table. The
|
|
type system guarantees that the admin interface sub-application that comes
|
|
out will always be free of the above-listed bugs, no matter which well-typed
|
|
table description is given as input.
|
|
|
|
The Ur/Web compiler also produces very efficient object code that does not use
|
|
garbage collection. These compiled programs will often be even more efficient
|
|
than what most programmers would bother to write in C. For example, the
|
|
standalone web server generated for the demo uses less RAM than the bash shell.
|
|
The compiler also generates JavaScript versions of client-side code, with no need
|
|
to write those parts of applications in a different language.
