Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

This JavaScript npm package provides all functions and constants that are assumed to be predeclared in the textbook Structure and Interpretation of Computer Programs, JavaScript Edition (SICP JS). This package therefore allows readers of the textbook to run and experiment with all JavaScript programs that appear in the textbook, using Node.js.

Alternatively, you can use the Source Academy, which has all necessary functions and constants predeclared.

Setting up and Using SICP package

You will need node version 16, and yarn.

Create the file package.json first if you have not done that, by running

$ yarn init

Add the following line in the package.json file

{
  ...
  "type": "module"
}  

Install the package sicp as follows:

$ yarn add sicp

To use any functions in the sicp package, you need to import them in your program by writing

import { <Functions here> } from 'sicp';

For example, if your file test.js contains:

import { display, head, list, tail } from 'sicp';

const p = list("I", "love", "sicp");
display(head(tail(p)));

you can check that everything is in place and then run your program:

% ls
node_modules    package.json    test.js         yarn.lock
% node test.js
"love"

The documentation of the functions and constants provided by the sicp package is available here.

This package is generated from the GitHub repository js-slang in the GitHub organization source-academy. Please report issues and bugs in this repository, using the prefix sicp: in the title.

Developers

To install a new version of sicp on npm, bump the version number in package.json and then run

% cd ..
% yarn build_sicp_package
% cd sicp_publish
% npm publish
