NAME

       gammu-smsd-run - documentation for RunOnReceive directive

DESCRIPTION

       Gammu  SMSD  can be configured by RunOnReceive directive (see gammu-smsdrc for details) to
       run defined program after receiving every message. It can receive single message  or  more
       messages, which are parts of one multipart message.

       This  parameter  is  executed  through  shell,  so  you  might need to escape some special
       characters and you can include any number  of  parameters.  Additionally  parameters  with
       identifiers  of received messages are appended to the command line. The identifiers depend
       on used service backend, typically it is ID of inserted row for database backends or  file
       name for file based backends.

       Gammu  SMSD  waits  for the script to terminate. If you make some time consuming there, it
       will make SMSD not receive new messages. However to limit breakage  from  this  situation,
       the  waiting  time is limited to two minutes. After this time SMSD will continue in normal
       operation and might execute your script again.

       NOTE:
          All input and output file descriptors are closed when this program is invoked,  so  you
          have to ensure to open files on your own.

ENVIRONMENT

       program  is executed with environment which contains lot of information about the message.
       You can use it together with NULL service (see gammu-smsd-null)  to  implement  completely
       own processing of messages.

   Global variables
       SMS_MESSAGES
              Number of physical messages received.

       DECODED_PARTS
              Number of decoded message parts.

   Per message variables
       The  variables  further  described  as  SMS_1_... are generated for each physical message,
       where 1 is replaced by current number of message.

       SMS_1_CLASS
              Class of message.

       SMS_1_NUMBER
              Sender number.

       SMS_1_TEXT
              Message text. Text is not available for 8-bit binary messages.

   Per part variables
       The variables further described as DECODED_1_... are  generated  for  each  message  part,
       where  1 is replaced by current number of part. Set are only those variables whose content
       is present in the message.

       DECODED_1_TEXT
              Decoded long message text.

       DECODED_1_MMS_SENDER
              Sender of MMS indication message.

       DECODED_1_MMS_TITLE
              title of MMS indication message.

       DECODED_1_MMS_ADDRESS
              Address (URL) of MMS from MMS indication message.

       DECODED_1_MMS_SIZE
              Size of MMS as specified in MMS indication message.

EXAMPLES

   Activating RunOnReceive
       To activate this feature you need to set RunOnReceive in the gammu-smsdrc.

          [smsd]
          RunOnReceive = /path/to/script.sh

   Processing messages from the files backend
       Following script (if used as RunOnReceive handler) passes message data to  other  program.
       This works only with the gammu-smsd-files.

          #!/bin/sh
          INBOX=/path/to/smsd/inbox
          PROGRAM=/bin/cat
          for ID in "$@" ; do
              $PROGRAM < $INBOX/$ID
          done

   Passing message text to program
       Following  script  (if  used  as  RunOnReceive  handler) passes message text and sender to
       external program.

          #!/bin/sh
          PROGRAM=/bin/echo
          for i in `seq $SMS_MESSAGES` ; do
              eval "$PROGRAM \"\${SMS_${i}_NUMBER}\" \"\${SMS_${i}_TEXT}\""
          done

   Passing MMS indication parameters to external program
       Following script (if used as RunOnReceive  handler)  will  write  information  about  each
       received  MMS  indication to the log file. Just replace echo command with your own program
       to do custom processing.

          #!/bin/sh
          if [ $DECODED_PARTS -eq 0 ] ; then
              # No decoded parts, nothing to process
              exit
          fi
          if [ "$DECODED_1_MMS_ADDRESS" ] ; then
              echo "$DECODED_1_MMS_ADDRESS" "$DECODED_1_MMS_SENDER" "$DECODED_1_MMS_TITLE" >> /tmp/smsd-mms.log
          fi

   Processing message text in Python
       Following script (if used as RunOnReceive handler) written in Python will concatenate  all
       text from received message:

          #!/usr/bin/python
          import os
          import sys

          numparts = int(os.environ['DECODED_PARTS'])

          # Are there any decoded parts?
          if numparts == 0:
              print('No decoded parts!')
              sys.exit(1)

          # Get all text parts
          text = ''
          for i in range(1, numparts + 1):
              varname = 'DECODED_%d_TEXT' % i
              if varname in os.environ:
                  text = text + os.environ[varname]

          # Do something with the text
          print('Number %s have sent text: %s' % (os.environ['SMS_1_NUMBER'], text))
