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 🙏

P2H4K - PDF to HTML converter for Kindle

CLI tool to convert scientific papers into Kindle readable HTML docs.

This project is pure beta.

Features

  • Adjusted pdf2htmlEX options and HTML/CSS optimizations for Converting Scientific Papers.
  • Some Math characters in HTML are captured as images to avoid characters being garbled.
  • Send the converted file to an endpoint at the end of the process (OPTIONAL).

This project focuses on the use of the Kindle Personal Document service. If you are interested in use for Kindle Direct Publishing, contact me.

Feature requests are also welcome.

Usage

p2h4k /path/to/your/pdf [--post <url>][-v, --version][-h, --help]

For More details about options, see --help

Install

This project depends on pdf2htmlEX and many npm projects.

Please setup node.js and pdf2htmlEX by yourself.

Windows

If your computer is based on Windows and pdf2htmlEX is installed on Windows subsystem for Linux 2, no modification is needed.

Run

npm install -g p2h4k

or

yarn global install p2h4k

Others

Notice This project is only tested on Windows.

If your PC has another setup, clone this project, then rewrite Converter Class init (in src/main.ts) with your pdf2htmlEX command.

// let c = new Converter("wsl pdf2htmlEX");
// processingFile = c.convert(wslPath(processingFile), wslPath(tempDir));

let c = new Converter("/path/to/your/pdf2htmlEX");
processingFile = c.convert(processingFile, tempDir);

then build with npm|yarn run build, then follow the instructions for Windows.

Known Difficulty

Text markup on Kindle does not work properly.

  1. Some texts cannot be selected.
  2. Texts sometimes wrap other texts (while all texts can be read).

Causes and solutions are still unknown.

Develop

P2H4K/src
│  convertpdf.ts        small debug script
│  main.ts              entry point
│  pdfUtils.ts          functions and classes to process HTML as strings or to call external APIs/tools.
│  playwright.js        provide web APIs to edit HTML
│  webScript.ts         scripts run in web (to be called by playwright.js)
│  webUtils.ts          classes for webScript.ts

Any help (or bug report) would be appreciated!

Todo

  1. Read all options from a single JSON file (converter path, endpoint, pdf2htmlex options,...)
  2. Config file generator
  3. Snapshot flag
