      Having trouble trying to figure out how to do this in one statement…

      Given:

      ~~~Some silly text~ more silly text~~~

      I’m trying to generate:

      ~.~.~Some silly text~ more silly text~.~.~.

      I feed Soarian results and it doesn’t accept the ~~ as a dual carrige return.  If I have any character after the tilde (except space unless there is a character prior to the next ~) the app generates a line feed.  So I’m trying to push periods in to get the app to line feed.

      Thoughts?

          Could you not regsub all the tildes “~” and replace with “~,” ?

            I’m trying to _only_ replace the ~ with ~. when there isn’t a space or another character.

            Any ideas?

              The problem is trying to do all of them.

              Try this

              set x “~~~Some silly text~ more silly text~~~”

              while {[regsub -all — {(~)(~)} $x {1 2} x]} {}

              echo $x

              => ~ ~ ~Some silly text~ more silly text~ ~ ~
