@david_megginson @HugoHeagren Currently, I use https://github.com/docbook/xslTNG which depends on the open source home edition of saxon XSLT processor to convert DocBook XML to HTML/ePub, and use #CSS based publishing softwares like https://vivliostyle.org or https://www.princexml.com/

There are zero actively maintained/usable on modern computers #SGML or #DSSSL processors known to me.

I got inspired to study #Scheme and I installed #drracket. Over 20 years ago I worked with #DSSSL, a subset of Scheme.

My goal is to write some scripts to parse large CSV files. I've used #Python for similar tasks.

@callionica HTML before 4.0 was defined with SGML which gives it the flexibility of auto closing tags, but I doubt any #SGML / #DSSSL implementation is still useable today and if people would still be willing to learn it after the language specification has been stale for a while

@juliobiason Actually, #CSS was not meant to fix #HTML. Independent stylesheets were planned from the beginning (as a parallel to #FOSI and #DSSSL for #SGML). (updated with the reference to FOSI, I knew that DSSL was just hacker-only non-corporate solution).

@benjedwards
Does AWK count? For Windows, I'd say Notepad++.

Long ago I formatted directories in #SGML. So big props to James Clark's #DSSSL engine, Jade.

For arcade games, I nominate Qix from #Taito, developed by Randy and Sandy Pfeiffer.

@reiver Interesting! I used to work with #SGML and defined the typesetting style documents using #FrameMaker and later with #DSSSL and Jade. #DescriptiveMarkup
