Creating PDFs in a Ruby on Rails application
You have a few options when trying to create a PDF in a Rails environment. Prawn and Wicked PDF have been around for quite a while. I have been using both gems and they work fine. However, they have a few limitations that can make it difficult to handle more complex PDFs. I recently discovered Grover, which can remediate some of this inflexibility in creating PDFs.

Has anyone tried Grover to generate PDF files on Heroku?
I am looking for a PDF generation tool for a Rails project. I have looked Prawn, Wicked and PDFKit, but Grover seems to be the most easy to use. The only thing concerns me is: in order to run Grover on Heroku, I will have to add 2 additional build packs (one for node.js and one for puppeteer). Can someone share their experience on how will the extra build packs affect performance on Heroku? Because I really do not want to slow the app down. My use case is a styled HTML property list that will be mostly 2 pages long.

Converting HTML to PDF using Rails
The gem I recommend is called Grover. It uses Puppeteer and Chromium to "print" an HTML page into a PDF. So your PDF will look exactly how your page looks in Google Chrome's print preview. This will also allow you to reuse CSS from your app rather than having to write specific CSS just for your PDF exports.

Question about Yard
An example for a very simple setup is the cmdparse gem documentation. It only has a few additional documentation files that accompany the main API documentation. The other end of the spectrum is the documentation for HexaPDF which encompasses many additional documentation files besides the API documentation and deeply integrates the API docs into the whole documentation website.

Understanding Text in PDF
Regarding TrueType font support: What I meant was that the library isn't a full TrueType font library but contains just the parts necessary for PDF supports. So what it can do is write a subset of a TrueType file because that's needed. But it can't serialize any arbitrary TrueType tables and it only handles those TrueType tables needed for displaying text in PDF. More advanced things like glyph positioning based on the language and characters in question is also not supported but may be in the future. Have a look at https://github.com/gettalong/hexapdf/tree/master/lib/hexapdf/font/true_type/ to see the implementation. All the things in this folder and below should be independent of PDF.
TrueType subsetting mainly consists of generating the necessary glyph and various index tables, and copying over all the other necessary tables which don't need to be adjusted. See https://github.com/gettalong/hexapdf/blob/master/lib/hexapdf/font/true_type/subsetter.rb for what is needed to subset.

One Class/Module per File Rules - Working With Nested Modules
Break the "rules" if need be. There is no need to separate out small classes into their own file because "something says so". If one were to look for the file of such a class, they would see there isn't one and automatically look into the file of the parent module/class. See e.g. https://github.com/gettalong/hexapdf/blob/master/lib/hexapdf/type/annotation.rb

Free / low cost software to remove a page from PDF on Windows 10?
There are a variety of command line tools like HexaPDF and qpdf that can do this; however, they need to be used on the command line.

Hooking into RDoc for better documentation with automatically executed examples
