I’d like to propose the tag
textprocessing for stories relating to text processing through computers. This means LaTeX, troff and other methods of computerized typesetting in particular, but would also include things like mandoc as a tool and formats like Markdown or DocBook. Posts like this get submitted on occasion, but they’re hard to fit into the existing tagging system.
I was thinking about just having a tag for typesetting in particular, but then found text processing seems to be popular on here, in a wider sense than merely typesetting.
Proposed description: “Computerized text processing and markup languages, such as LaTeX”
Examples that I believe the tag would be a good fit for:
