Quotes in string (f)lex AT&T

Question

How can I write a regular definition in (f)lex for quoted strings from AT&T language?

Example of string that come to my mind:

• "abc"
• "a\"bc"
• "abc\"
• "abc\""

Later edit:

• "abc" "def" should be matched as two strings
• "ab\"c" "def" should be matched as two strings
• "abc\" "def" should be matched as two strings

The definition \"[^\"]\" is not working because it will match "abc" "def" as one string.

Answer 1

could you be more specific as to what strings you are trying to match? Strings that start and end with "? What do you mean by AT&T language?
