Q&A Syntax summaries use brackets for optional elements; how do I represent literal brackets in a way readers will understand?

A fairly common solution I've seen to issues like this is to use different font faces for literal text and meta-notation. Often it will be a monospace "teletype" or sans-serif font for literal text...

Note that the styles are not rendered.
  • A fairly common solution I've seen to issues like this is to use different font faces for literal text and meta-notation. Often it will be a monospace "teletype" or sans-serif font for literal text and a contrasting (usually lighter) variable width font for meta-notation.
  • For your example, you'd get:
  • <span style="font-family: monospace">ARRAY[</span> *data-type*[ <span style="font-family: monospace">,</span> *count*] <span style="font-family: monospace">]</span>
  • In case that doesn't render well, here are compromise mimics using `code`:
  • `ARRAY[`*data-type*[`,` *count*]`]`
  • or **bold**:
  • **ARRAY[** *data-type*[ **,** *count*] **]**
  • Other text decorations such as underlining could be used to make it clear what is literal text. I've mostly seen this in older hand-typed documents.
  • As you can tell from the examples, it is easy to distinguish the literal brackets from the meta-brackets.
  • Whatever the approach, it would be explicitly documented in the early part of the documentation but is often intuitive enough even if someone skips that explanation.
