> Sometimes I feel that contemporary markup languages like Markdown, Textile, etc. fall short compared to the syntax that was just as readable and quite a bit more powerful in troff... I've never used troff myself, but your comment prompted me to look at the spec for it. I also searched for a "markdown vs troff" comparison, but didn't have much luck. Do you know of a head-to-head comparison? I've been using markdown for the past year or so when I don't need the full power of LaTeX. But your comment has me wondering if I'd be better off just using troff?

troff takes a little bit more work but it can put out some very nice-looking documents with a lot of control over the formatting and some pretty handy utilities for tables and math and such. For example, pretty much all the Plan 9 papers were written in troff: https://9p.io/sys/doc/ https://9p.io/sys/doc/

  Okay. I guess what I'm wondering is, if I'm already reasonably proficient in LaTeX (for documents where I want/need lots of control) is there an advantage to learning/using troff versus using markdown?

    No two latex installations are the same.

        In my opinion, I'd say pull out troff if you're thinking about making a PDF, or if you want tables or equations (see http://www.troff.org/prog.html http://www.troff.org/prog.html). Personally, I mostly use markdown when I want to generate some HTML but don't feel like typing tags by hand, or just as a sort of "style guideline" when writing text files.

        I meant when in two years you add something to your tex file and make blows-up, that's a reason to use roff if you can get away with it.

        Gotcha, thanks for the clarification. I guess I don't use very many "exotic" packages, so I haven't had much of an issue with old LaTeX files not compiling. Though, I also rarely have to go back and recompile them.

It's not bad. It's got some not-entirely-awful metaprogramming features; a while back I got interested in it and wrote a 'modern' macro package proof-of-concept for it: http://cowlark.com/meta http://cowlark.com/meta Example input follows. Defining a paragraph style in meta: .STYLE TITLE . FONT SANS . FACE B . FONTSIZE 30 . ALIGNMENT CENTER ./STYLE ...and using it: .TITLE The meta macro package ./TITLE This is a very simple, noddy example of how to use the meta macro package. It's not intended to be a reference (there currently isn't one). But the core language is kinda horrible, needing a really hacky implementation, and you can't define inline macros --- the \fB and \fP above are built-ins. Macro invocations have to start on new lines. In fact, this isn't a bad limitation in practice for anything even slightly heavyweight, but for italics, bold and underline it's still nice to have inline markup.

The troff suite includes eqn for equations, pic for diagrams, etc. that make it more like TeX in its capabilities than HTML like for Markdown etc. http://www.troff.org/prog.html#pic http://www.troff.org/prog.html#pic And the basic inline markup tags are, at least in my opinion, just as simple as Markdown, Textile, or AsciiDoc.
