NAME

   tcl::transform::spacer - Space insertation and removal

SYNOPSIS

   package require Tcl  8.6

   package require tcl::transform::core  ?1?

   package require tcl::transform::spacer  ?1?

   ::tcl::transform::spacer chan n ?space?

______________________________________________________________________________

DESCRIPTION

   The  tcl::transform::spacer  package  provides  a  command  creating  a
   channel transformation which adds spacing to the data  written  to  it,
   and removes such spacing from the data read from it.

   The  internal  TclOO class implementing the transform handler is a sub-
   class of the tcl::transform::core framework.

API

   ::tcl::transform::spacer chan n ?space?
          This command creates a  spacer  transformation  on  top  of  the
          channel chan and returns its handle.

          The space character sequence will be added every n bytes of data
          written, and on the read side  the  same  is  done  in  reverse,
          removing the spacing. If space is not specified it defaults to a
          single space character (ASCII 32).
