NAME
       uuencode - UU-encode/decode binary data

SYNOPSIS
       package require Tcl  8

       package require uuencode  ?1.1.4?

       ::uuencode::encode string

       ::uuencode::decode string

       ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)

       ::uuencode::uudecode (-file filename | ?--? string)

DESCRIPTION
       This  package  provides  a  Tcl-only implementation of the uuencode(1) and uudecode(1) commands. This
       encoding packs binary data into printable ASCII characters.

       ::uuencode::encode string
              returns the uuencoded data. This will encode all the data passed in even  if  this  is  longer
              than  the  uuencode  maximum  line length. If the number of input bytes is not a multiple of 3
              then additional 0 bytes are added to pad the string.

       ::uuencode::decode string
              Decodes the given encoded data. This will return any padding characters as well and it is  the
              callers responsibility to deal with handling the actual length of the encoded data. (see uuen-code). uuencode).
              code).

       ::uuencode::uuencode ?-name string? ?-mode octal? (-file filename | ?--? string)

       ::uuencode::uudecode (-file filename | ?--? string)
              UUDecode a file or block of data. A file may contain more than one embedded file so the result
              is a list where each element is a three element list of filename, mode value and data.


OPTIONS
       -filename name
              Cause  the  uuencode  or  uudecode commands to read their data from the named file rather that
              taking a string parameter.

       -name string
              The uuencoded data header line contains the suggested file name to be used when unpacking  the
              data. Use this option to change this from the default of "data.dat".

       -mode octal
              The  uuencoded  data  header line contains a suggested permissions bit pattern expressed as an
              octal string. To change the default of 0644 you can set this option. For instance, 0755  would
              be suitable for an executable. See chmod(1).


EXAMPLES
       % set d [uuencode::encode "Hello World!"]
       2&5L;&\\@5V]R;&0A



       % uuencode::uudecode $d
       Hello World!



       % set d [uuencode::uuencode -name hello.txt "Hello World"]
       begin 644 hello.txt
       +2&5L;&\@5V]R;&0`
       `
       end



       % uuencode::uudecode $d
       {hello.txt 644 {Hello World}}
