![]() Adjust top-level compilation to accomodate an `#%app` macro that expands to definitions. Allowing `#%app` to expand to a non-expression is more consistent with expansion in a module. There's still an issue with top-level expansion where (define-syntax-rule (#%app id) (begin (define-syntax (id stx) 'ok) id)) does not work, because the kind of partial expansion used for the top level doesn't trigger `#%app`, and so the macro and use are expanded together in a `begin` instead of separately. Changing that would be subtle and maybe not worthwhile for the top level. Also, although the behavior of the (very) old expander may not be relevant anymore, it behaved the same way on that example. Closes #3728 |

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.
This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.
Quick Start
Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at
https://download.racket-lang.org
Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at
Building from Source
