BiwaScheme 是一个用 JavaScript 编写的 Scheme 解释器。
适用于网络浏览器（包括移动设备）和 Node.js。
这个分支旨在使 Node.js 的上游 BiwaScheme 适应 web worker 和 Node 的工作线程。 此外，系统 API（套接字、文件系统、导入……）被中和，期望在线程中运行的 Scheme 程序是封闭系统。

How to use
只需加载 biwascheme.js（或 biwascheme-min.js）并编写 Scheme 代码。
<!DOCTYPE html>
<html>
<body>
<div id="bs-console"></div>
<script src="biwascheme.js"></script>
<script type="text/biwascheme">
(display "hello, world!")
</script>
</body>
</html>
How to use with node.js to run a biwa script
$ npm install biwascheme
create a file a.scm:
(display "Hello, world!") （换行符）
$ biwas a.scm
How to use from inside node.js as a module
$ npm install biwascheme
创建文件 a.js：
var BiwaScheme = require("biwascheme"); BiwaScheme.run("(+ 1 2)"); // 或 BiwaScheme.run_file("a.scm");
$ node a.js
Conformance
BiwaScheme 实现 R7RS small，包括一流的延续和尾调用优化。
主要缺乏的特性是：
- syntax-rules
- Exceptions
- Library system
JavaScript 有两个限制。 这些不会被修复（技术上可以修复但效率非常低）。
- Strings are immutable
- Integers are not distinguished from float

BiwaScheme is a Scheme interpreter written in JavaScript.
Works with web browsers (including mobile devices) and Node.js.
This fork aims to adapt the upstream BiwaScheme for Node.js to web workers and Node's worker threads. Also, the system APIs (sockets, filesystem, imports…) are neutralized, expecting Scheme programs running in threads to be closed systems.

How to use
Just load biwascheme.js (or biwascheme-min.js) and write Scheme code.
<!DOCTYPE html>
<html>
<body>
<div id="bs-console"></div>
<script src="biwascheme.js"></script>
<script type="text/biwascheme">
(display "hello, world!")
</script>
</body>
</html>
How to use with node.js to run a biwa script
$ npm install biwascheme
create a file a.scm:
(display "Hello, world!") (newline)
$ biwas a.scm
How to use from inside node.js as a module
$ npm install biwascheme
create a file a.js:
var BiwaScheme = require("biwascheme"); BiwaScheme.run("(+ 1 2)"); // or BiwaScheme.run_file("a.scm");
$ node a.js
Conformance
BiwaScheme implements most of the features of R7RS small, including first-class continuation and tail call optimization.
Major lacking features are:
- syntax-rules
- Exceptions
- Library system
There are two limitations that arise from JavaScript. These will not be fixed (it's technically possible to fix but will be very inefficient).
- Strings are immutable
- Integers are not distinguished from float
