haskell-ux VS pandoc

> I think that Haskell is a great language to prototype pure business logic because of the type system and focus on purity, but it has several warts, because haskellers focus more on language research than DX.

This is very true. We recently started https://github.com/digitallyinduced/haskell-ux to keep track of haskell DX improvements. Some of our suggestions are already issues on the GHC (haskell compiler) bug tracker.

Here's an example of a great UX improvement in GHC: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/4711

pandoc has a feature called filters. These filters are small programs that can manipulate the AST of the document. They can be written in any language, but the most common language is Lua as its interpreter is embedded in pandoc, and it is faster compared to the JSON filter interface which is also used by other languages (You may wish to listen to the Episode 37 of The Haskell Interlude podcast, where Joachim Breitner and David Christiansen interview John MacFarlane, the creator of pandoc, where he mentions Lua vs JSON filters).

PDF and Epub support a featureset that far exceeds Markdown in it's basic specification. Translating from one to the other would be pretty lossy, but possible.

You could probably use Pandoc to do this yourself, but again I'd stress that this is a pretty poor way to translate the original document: https://pandoc.org/

My main authoring tool is then Emacs Markdown Mode (https://jblevins.org/projects/markdown-mode/). For data entry, it comes with some bells and whistles similar to org-mode, like C-c C-l for inserting links etc.

I seldom export my notes for external usage, but if it is the case, I use lowdown (https://kristaps.bsd.lv/lowdown/) which also comes with some nice output targets (among the more unusual are Groff and Terminal). Of cource pandoc (https://pandoc.org/) does a very good job here, too.

This is one of those things that the ever-amazing pandoc (https://pandoc.org/) does very well, on top of supporting virtually every other document format.

Folks feel the same way about Markdown versus LaTeX: why use something significantly more complicated where a looser, human-readable grammar works better?

For any other situations, I use https://pandoc.org/, or, generate a Word doc scriptomatically.

Congrats on the launch, I guess, but there are so many free options that I can't think of a situation where paying $0.25 per document would be justified...? Just to name a few:

Back in the days, I used to use XSL-FO [0] and it was okay. It was not very precise but it rarely if ever broke, and was perfectly integrated with an XML/XSLT solution. Yeah, this was a long time ago.

Last month I used html-to-pdfmake [1] and it's also not very precise and more fragile, but very efficient and fast.

Yet another approach would be to pro grammatically generate .rtf files (for example) and use Pandoc [2] to produce PDFs (I have not tried this in production but don't see why it wouldn't work).

Others have mentioned static site generators. I like Hakyll [1] because it can tightly integrate with Pandoc [2] and allows you to develop custom solutions if your needs ever grow.
