## 1. Project Overview & Quickstart (cisco/ChezScheme) [](https://github.com/cisco/ChezScheme/actions/workflows/ci.yml) *Tip: Clone this repo with* `git clone --filter=blob:none` *to avoid eagerly downloading large boot files for older versions.* Chez Scheme is both a programming language and an implementation of that language, with supporting tools and documentation. Supported platforms (bytecode interpreter may work for others): * Windows: x86, x86_64, AArch64 * Mac OS: x86, x86_64, AArch64, PowerPC32 * Linux: x86, x86_64, ARMv6, AArch64, RV64G, LoongArch64, PowerPC32 * FreeBSD: x86, x86_64, ARMv6, AArch64, PowerPC32 * OpenBSD: x86, x86_64, ARMv6, AArch64, PowerPC32 * NetBSD: x86, x86_64, ARMv6, AArch64, PowerPC32 * Solaris: x86, x86_64 * GNU/Hurd: x86, x86_64 * Haiku: x86_64 * Android: ARMv7, AArch64 * iOS: AArch64 * WebAssembly via Emscripten (bytecode interpreter only) As a superset of the language described in the [Revised6 Report on the Algorithmic Language Scheme](http://www.r6rs.org) (R6RS), Chez Scheme supports all standard features of Scheme, including first-class procedures, proper treatment of tail calls, continuations, user-defined records, libraries, exceptions, and hygienic macro expansion. Chez Scheme also includes extensive support for interfacing with C and other languages, support for multiple threads possibly running on multiple cores, non-blocking I/O, and many other features. The Chez Scheme implementation consists of a compiler, run-time system, and programming environment. Although an interpreter is available, all code is compiled by default. Source code is compiled on-the-fly when loaded from a source file or entered via the shell. A source file can also be precompiled into a stored binary form and automatically recompiled when its dependencies change. Whether compiling on the fly or precompiling, the compiler produces optimized machine code, with some optimization across separately compiled library boundaries. The compiler can also be directed to perform whole-program compilation, which does full cross-library optimization and also reduces a program and the libraries upon which it depends to a single binary. The run-time system interfaces with the operating system and supports, among other things, binary and textual (Unicode) I/O, automatic storage management (dynamic memory allocation and generational garbage collection), library management, and exception handling. By default, the compiler is included in the run-time system, allowing programs to be generated and compiled at run time, and storage for dynamically compiled code, just like any other dynamically allocated storage, is automatically reclaimed by the garbage collector. The programming environment includes a source-level debugger, a mechanism for producing HTML displays of profile counts and program "hot spots" when profiling is enabled during compilation, tools for inspecting memory usage, and an interactive shell interface (the expression editor, or "expeditor" for short) that supports multi-line expression editing. The R6RS core of the Chez Scheme language is described in [The Scheme Programming Language](http://www.scheme.com/tspl4/), which also includes an introduction to Scheme and a set of example programs. Chez Scheme's additional language, run-time system, and programming environment features are described in the [Chez Scheme User's Guide](http://cisco.github.io/ChezScheme/csug/csug.html). The latter includes a shared index and a shared summary of forms, with links where appropriate to the former, so it is often the best starting point. Get started with Chez Scheme by [Building Chez Scheme](BUILDING). For more information about the implementation and a guide to modifying Chez Scheme, see [implementation notes](IMPLEMENTATION.md).

Before starting work on a new feature, enhancement, or fix, please create an issue and optionally assign it to yourself or a developer. 1. Fork the repository and make your changes against the 'development' branch (not master). 1. After making your changes in your fork, run tests and ensure that the page looks good and works with all supported browsers. 1. If you have made a series of commits into the 'development' branch, please try to squash them into a small number of commits. 1. Issue a Pull Request against the 'development' branch (not master). 1. The admins will review your code and may optionally request conformance, functional or other changes. Work with them to resolve any issues. 1. Upon acceptance, your code will be merged into the master branch and will become available for all. ## Don't See Your Project Here? 1.
