# Description:
# Example trigger script to write changelist and list of files that fixed job to a
# job field so they can be copied to JIRA by P4DTG. If this feeld is configured
# to render using the 'WIKI style' renderer. More information on this can be
# found in:
#    https://confluence.atlassian.com/display/JIRA/Configuring+Renderers
#
# Important Note:
# This is only an example script to demonstrate how you could use P4DTG to
# replicate data and have it displayed as an active URL to p4web in JIRA.
# It has not been tested and is not ready to be installed in a production
# environment. 
#
# Example usage:
# (1) Create a custom Text field in the Perforce jobspec.
#      	135 P4WebURLS text 0 optional
#  
# (2) Create a custom 'Free Text Field (unlimited text)' in JIRA and configure
#     it to render with a custom renderer.
#
# (3) Modify 'jira-config.xml' and set the JIRA custom field to be
#     type 'TEXT'. For example:
#        <CustomField name="CustomTextField" type="TEXT" access="RW" />
#
# (4) Use P4DTG-Config to 'Check Connection' to the JIRA source, click
#     'Apply' then map P4WebURLS-->CustomTextField.
#
# (5) Test the trigger at the command line by output a job that has fixes
#     to a text file, then running the script against this file. For
#     example:
#        p4 job -o job001234 > tmp.txt
#        perl jira6_p4web_url_trigger.pl tmp.txt job001234
#     After running the script 'tmp.txt' should contain the change and list
#     of files in P4Web URL format.
#
# (6) Modify the environment section below to match your Perforce and
#     P4Web settings. 
#
# (7) Creat a 'form-out' trigger definition for the script.
#     Triggers:
#	       jira form-out job "perl ./jira6_p4web_url_trigger.pl %formfile% %formname%"
#
