That scalable vector graphic on the page shows source document type on the left and target type on the right. TL;DL: It converts about two dozen document types into about three dozen document types.
P.S.E.G.: PDF ← Markdown ←→ HTML → PDF
P.P.S: Where are my manners? Image transcription added to post.
The author is also involved in a markup language called djot, which is like markdown, but well-defined. It's an awesome language that will probably languish under markdown's dominance.
Like a data format inhabiting the centre of that conversion graph they have on their website, basically a superset of the available input types, that is then version controlled by git, and can be exported to any of the output formats, in a neat frontend that removes all that complexity from me. :D
Well every one already recommended latex or markdown.
I would also recommend typst, it's a modern latex alternative easy to make templates and a markdown like syntax, none of all the backslash keywords that I somehow always forget.
I made a template a while back when I had to make report, since I had a professor that disliked the markdown look of previous ones.
A bit of a learning curve, but once you get the hang of it, you make a few templates and write on them just like markdown with custom alias and whatnot.
Typst is fucking amazing. LaTeX is powerful but just takes too much effort to use for large part of the population to the point that I just can't recommend it to most people outside STEM. Typst is consistent, easier to use, faster, and collaborative. With no nonsensical error messages, broken builds, and technical debt - I can actually recommend it to most.
Haha, kind of. However conversion between all these formats is lossy in some directions and I don't know of any software that integrates version control of documents by default (not saying there are none).
I am confused what would be the combined functionality of the merged product. Do you need to output of converted files to be added to git when a document is version controlled?
No Pandoc isn’t an editor by any means. It’s an document conversion tool. Think converting a Markdown file into an docx or html or epub or pptx or pdf (via LaTeX or ConText). That’s what pandoc does.
If I'm understanding your question right, kind of. Pandoc is only for document conversion though, no spreadsheets, presentations, etc. But at that it can convert between a lot of formats. And git can be used to version and share those documents.
