convert #hashtag and @user of inbound mail to JIRA labels and watchers

[Matt Snow]

I am looking for a way to have labels and watchers added to new JIRA issues created through email based on social media like @mentions and #hashtags.

The idea is that to parse email inputs (an incoming mail handler plugin/script, or ScriptRunner event Listener) for use of @userid and #hashtag.

If an @userid is found, check if user exists in directory, if so add them as a watcher.

If a #hashtag is found, add it to the labels field in if the issue.

JEMH can do this with its Regexp Field Processor, If CSV is an acceptable approach for mulitple values, rather than mulitple lines, ie:

@value1,value2,value3

rather than
@value1
@value2
@value3

You'd create a  Regexp Field Processor 'Field Mapping' for the Key 'watchers'

\n@([A-Za-z0-9,]+)\n

Then, an email with payload:

some text

@user1,user2

would be extracted, and set as watchers.

Likewise, a Field mapping expression for the key 'Labels':

\n#([A-Za-z,]+)\n

Would match on XX,YY,ZZ:

some text

@user1,user2,user3
#XX,YY,ZZ

These values would then be added as labels.

Removal of these values from the comment being added is also possible, through JEMH Pre-Processing > Body Cleanup Regexps (Body Cleanup Order : After Directives)

I found a few edge-case bugs along the way proving this sceanrio, (no new lines at the end of the email on the last line) but will be fixing this up in the next build for 7.4 (JEMH-5861)
