LIPS offers a powerful Scheme-based Lisp interpreter built using JavaScript. It provides seamless interaction with JS, allowing developers to harness the full capabilities of JavaScript, Lisp, and npm together. Perfect for building versatile applications with a unique programming approach.
LIPS is a robust Scheme-based Lisp interpreter built in JavaScript that enhances interaction with existing JavaScript platforms. Designed to comply with the R5RS and R7RS specifications, LIPS unlocks the full potential of both JavaScript and Lisp, providing a versatile environment for developers. This interpreter functions seamlessly in both browser environments and Node.js, making it highly accessible for various applications.
Incorporate LIPS into web pages using script tags:
<script type="text/x-scheme" bootstrap>
(let ((what "world")
(greet "hello"))
(display (string-append greet " " what)))
</script>
Or reference an external source:
<script type="text/x-scheme" bootstrap src="example.scm"></script>
Access the REPL with the following command:
lips
For scripting, use shebang:
#!/usr/bin/env -S lips
(print "Hello, world!")
After saving this to hello.scm, make it executable and run it:
chmod a+x hello.scm
./hello.scm
As a tree-walking interpreter, LIPS may experience performance lags when processing lengthy arrays or when using complex callbacks, particularly within frameworks like React. Strategies such as writing performance-intensive tasks in JavaScript can mitigate these issues.
LIPS supports various SRFIs (Scheme Requests for Implementation) which enhance its functionality:
For a full list of supported SRFIs and additional details, refer to the official documentation.
Engage with the LIPS community on Gitter for discussions or queries. Stay updated on project developments through the official website or follow on Twitter.
By providing a modern Lisp environment within JavaScript, LIPS aims to streamline development processes, enabling users to harness the strengths of both languages efficiently.
