Better with or without hyphen?

Use dollar-quoted strings to simplify!
Use dollar-quoting to simplify!

Does it matter whether the second part is another noun?
And does it make a difference whether the compound word is used as adjective?

(The dollar character $ can be used to quote strings in the database system PostgreSQL. Hence the technical term. Examples here and here.)

  • Better with the hyphens, and no to your other questions. The compounds "dollar-quoted" and "dollar-quoting" are verb-centred compound adjectives. – BillJ Mar 27 '18 at 13:49
  • The answer and the linked site seem to disagree on your first part. And are you sure "dollar-quoting" serves as adjective in the example? – Erwin Brandstetter Mar 28 '18 at 17:15

It really depends on context.

  1. "Dollar quotes" or "dollar quoting" as a noun phrase: "Sometimes you need dollar quotes when using Postgresql."
  2. "Dollar-quoted" as a compound adjective: "Dollar-quoted strings simplify your life."

So, your first line depends on if there is even a sentence. The second line should be hyphenated, and the last line should not be hyphenated.
