[TxMt] export property list keys as BASH variables

[Hans-Joerg Bibiko]

Hi,

of course I forgot something.

In order to be able to have access from a perl, python, ruby, etc.  
script I export these BASH variables now.

On the other hand there is still one question:

I set the value to an empty string if the given key is not set as key  
witin the plist. Is there a better way? I believe it is ok and the  
user has to catch this by itself.

Bye,

Hans

#
#   exportpl set BASH variables according to the property list <key>=<value>
#
#    if <value> is an array tag a BASH array will be returned
#    if <value> is a date tag output format YYYY-MM-DDTHH:MM:SSZGMTshift
#
#    all variable values are UTF-8 encoded
#
#    if a given key is not specified in plist an empty string will be returned
#
#    each variable is named $TMD_<key>
#
#   Usage:
#
#     exportpl <data|file> {key1 key2 key3 ... keyn}
#
#     data        := string containing valid plist data
#     file        := plist file [.plist extension is not necessary]
#     key1...keyn :=　valid key(s) for plist
#
#
#   Examples: (output is an array with 8 items)
#
#   a)
#   KEY=("returnCode" "output")
#   . "$TM_BUNDLE_SUPPORT"/bin/exportpl.sh "$TM_BUNDLE_SUPPORT"/bin/test.plist ${KEY[@]}
#   echo $TMD_returnCode
#   echo ${TMD_output[0]}
#
#
#
#   b)
#   . "$TM_BUNDLE_SUPPORT"/bin/exportpl.sh "$TM_BUNDLE_SUPPORT"/bin/test returnCode output
#   echo $TMD_returnCode
#   echo ${TMD_output[5]}
#
#   c)
#   DIA=$( cat "$TM_BUNDLE_SUPPORT"/bin/test.plist | tm_dialog -m test )
#   . "$TM_BUNDLE_SUPPORT"/bin/exportpl.sh "$DIA"
#   #all key(s) for $DIA are exported
