NAME

     applesingle, binhex, macbinary -- encode and decode files

SYNOPSIS

     <tool> probe file ...
     <tool> [decode] [-c] [-fv] [-C dir] [-o outfile] [file ...]
     <tool> -h | -V

     applesingle encode [-cfv] [-s suf] [-C dir] [-o outfile] file ...
     binhex encode [-R] [-cfv] [-s suf] [-C dir] [-o outfile] file ...
     macbinary encode [-t 1-3] [-cfv] [-s suf] [-C dir] [-o outfile] file ...

DESCRIPTION

     applesingle, binhex, macbinary are implemented as a single tool with multiple names.  All invocations support the three verbs encode, decode,
     and probe.

     If multiple files are passed to probe, the exit status will be non-zero only if all files contain data in the specified encoding.

OPTIONS

     -f, --force
	      perform the operation even if the output file already exists

     -h, --help
	      display version and usage, then quit

     -v, --verbose
	      be verbose

     -V, --version
	      display version, then quit

     -c, --pipe, --from-stdin, --to-stdout
	      For decode, read encoded data from the standand input.  For encode, write encoded data to the standard output.  Currently, "plain"
	      data must be written to and from specified filenames (see also mount_fdesc(8)).

     -C, --directory dir
	      create output files in dir

     -o, --rename name
	      Use name for output, overriding any stored or default name.  For encode, the appropriate suffix will be added to name.  -o implies
	      only one file to be encoded or decoded.

     -s, --suffix .suf
	      override the default suffix for the given encoding

     -R, --no-runlength-encoding
	      don't use BinHex runlength compression when encoding

     -t, --type 1-3
	      Specify MacBinary encoding type.	Type 1 is undesirable because it has neither a checksum nor a signature and is thus difficult to
	      recognize.

DIAGNOSTICS

     In general, the tool returns a non-zero exit status if it fails.

NAME

       base64 - base64-encode/decode binary data

SYNOPSIS

       package require Tcl  8

       package require base64  ?2.4.2?

       ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string

       ::base64::decode string

_________________________________________________________________

DESCRIPTION

       This package provides procedures to encode binary data into base64 and back.

       ::base64::encode ?-maxlen maxlen? ?-wrapchar wrapchar? string
	      Base64  encodes  the  given  binary string and returns the encoded result. Inserts the character wrapchar every maxlen characters of
	      output. wrapchar defaults to newline. maxlen defaults to 76.

	      Note well: If your string is not simple ascii you should fix the string encoding before doing base64 encoding. See the examples.

	      The command will throw an error for negative values of maxlen, or if maxlen is not an integer number.

       ::base64::decode string
	      Base64 decodes the given string and returns the binary data.  The decoder ignores whitespace in the string.

EXAMPLES

       % base64::encode "Hello, world"
       SGVsbG8sIHdvcmxk

       % base64::encode [string repeat xyz 20]
       eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6
       eHl6eHl6eHl6
       % base64::encode -wrapchar "" [string repeat xyz 20]
       eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6eHl6

       # NOTE: base64 encodes BINARY strings.
       % set chemical [encoding convertto utf-8 "Cu2088Hu2081u2080Nu2084Ou2082"]
       % set encoded [base64::encode $chemical]
       Q+KCiEjigoHigoBO4oKET+KCgg==
       % set caffeine [encoding convertfrom utf-8 [base64::decode $encoded]]
