Escape character in {dlgchoose}?

aussieboykie · July 22, 2009, 10:28pm

What I want is..

{dlgchoose|Plus or Minus?|Plus=++Minus=-}

..but of course every + is interpreted as a separator. Is there a way of escaping the first + sign?

You can put quotes around the values, but the problem is that you then get the quotes inserted into the command as well.

{dlgchoose|Plus or Minus?|Plus="+"+Minus="-"}

i.e. That will return "+" or "-" with the quotes.

Not sure if there is a way to do it without the quotes.

You could use something like this:@set strTest = Plus=+Minus=- {dlgchoose|Plus or Minus?|{$strTest}}

This works for Minus (returns -) but not for Plus (returns Plus).

What are you doing with the results of the dlgchoose ?

I'm building a parameter string to pass to an external program. The string needs to include a plus or minus sign. I have tested enclosing the finished parameter string in quotes and it works, so I have a way of bypassing the problem using the method Leo proposed. This is obviously not a common problem, but it would be nice to have a way of escaping the + symbol. One way would be a control code that lets the user define the separator as something other than + (the default).

@stringsep = ;

An alternative approach would be to add support for a @skip [n] control code which could be used to implement a simple if construct by ignoring "n" command lines like so:

@set plusminus = - @set n = {dlgchoose|Plus or Minus?|Plus=0+Minus=1} @skip {$n} @set plusminus = + @set string = some text {$plusminus} some more text
