put the tokens of "put" && quote & "something" & quote && "--comment" results in put "something without the trailing quote.
That's not quite what I see - I get just
put something
i.e. without either quote; that makes sense because once the line is tokenized, the quotes are unnecessary.
Sorry - my error. I had already changed my script to investigate the case described later in my email (put a+b into c)
So (naturally enough, with hindsight) using something like token N returns JUST the token itself, whereas token N to K returns the intervening delimiters, but not any trailing one.
So we only need to restore any trailing quote, which is only needed if the final token started out being quoted, therefore
function StripComments theLine local theResult put token 1 to -1 of theLine into theResult if quote is in token -2 to -1 of theLine then put quote after theResult return theResult end StripComents
should do it OK. Seems to work for my simple testing so far - but there may be cases I haven't thought of yet.
Unfortunately, it appears that token DOES include the C-style comment delimiters recently introduced, and they can be multi-line, so you'll need to do something more to deal with that.
