For example: -% -% "This is a test." ---> ``This is a test.'' -% -% The double-quote character is still available via \dq. (\" is still -% treated as the umlaut accent.) -% -% This macro makes a couple of assumptions about the double-quotes: -% -% 1. Double-quotes are assumed to come in pairs. When replacing -% double-quotes, the macro alternates between `` and ''. The only -% exception to this is noted in (2) below. -% 2. A double-quote at the beginning of a paragraph is always treated -% as ``. This correctly handles the case where a quotation is -% continued into a second paragraph: -% -% "This is the first paragraph.\par -% "This is the second paragraph of the same quote." -% -% Normal TeX spacing after `` and '' is maintained by saving and -% restoring the \spacefactor. -% -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -% -% HOW IT WORKS: -% -% The double-quote character (") is made active by \begindoublequotes. -% The " macro keeps track of left-quote/right-quote pairs and inserts -% the appropriate `` and '' in its place. -% -% Each character has a \spacefactor associated with it, which specifies -% the amount of stretch or shrink that a space following the character -% can have. Most characters have a factor of 1000, but some punctuation -% marks have higher spacefactors, most notably the period, which has a -% \spacefactor of 3000. This means the space following a period can -% stretch up to 3 times more than the space after a regular character, -% accounting for the increased space at the end of sentences. -% -% The `` and '' ligatures are assigned \spacefactor's of 0, so that the -% \spacefactor that is applied to the next character is the same as that -% of the character preceding the quotes. Because " has been redefined as -% a macro, any spaces following " are swallowed by TeX. It was necessary -% to have this macro re-insert any needed space so that the following -% cases worked correctly: -% -% "This is a test," she said. --> ``This is a test,'' she said. -% "This is in a list"; etc. --> ``This is in a list''; etc. -% -% Without the added space, the first example becomes: -% -% ``This is a test,''she said. -% -% The solution was to save the current \spacefactor before inserting a -% right double-quote, then resetting the \spacefactor after the -% insertion. The net effect was that the " macro has a \spacefactor -% of 0, which matches the way TeX treats `` and ''. -% -%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -{% % Begin a group for which " is active -\catcode`\"=\active % Make " an active character -\catcode`\@=11 % Make @ an active character -% -% \begindoublequotes -% -% This macro makes " an active character, resets the control sequence -% \dblqu@te to L (left), and defines \dq as a replacement for ". -% -\gdef\begindoublequotes{% % \begindoublequotes enables " - \global\catcode`\"=\active % Make " an active character - \global\chardef\dq=`\" % Double-quote char. via \dq - \global\let\dblqu@te=L % Always start with a left double-quote - } % End of macro -% -% Define the macro that will be executed whenever " is encountered. -% -\gdef"{% - % If the double-quote is the first character in a new paragraph, - % make sure it becomes a left double-quote.
