WFA advanced incremental naming

In a previous post, I already explained how incremental naming works.  (http://www.wfaguy.com/2016/12/incremental-naming.html#more)

However, sometimes you need something a bit more advanced.
For example you need this incremental functionality

- myvol50xx
- myvol51yy
- myvol52zz

Using the classic incremental naming functionality, this no longer works as we have a changing suffix.

In this case you need to follow these steps :

1. create a custom filter with regex (e.g. WHERE name REGEXP '${regex}'
   Search for the last item by using this regex '^myvol[0-9]{2}.*$
   => Hint : use skip this step if not found !
2. Then use the _found property like this :
   (volume_last._found)?Integer.parseInt(getRegexMatch(volume_last.name,"^(myvol)([0-9]{2})(.*)$",2))+1:1
   
   This seems complex, but isn't.
• If last volume found
• Strip number from last volume
• regex = ^myvol([0-9]{2})(.*)$
  This regex will parse your name and create 4 matches (using the brackets)
  Match 0 = the full string
  Match 1 = the string "myvol"
  Match 2 = the number
  Match 3 = the suffix
  In our case, we grab match 2 (the number)
• And increase by 1
• If not found
• Return 1
3. Finally use the number to reassemble the new name
   'myvol' + padNumber(NEW_NUMBER,2) + 'mysuffix'

The function "getRegexMatch", you can find on my github (https://www.github.com/wfaguy) 

Along this function you can find interesting others.  I recently added a few new ones like :

• trimEnd
• getRegexMatch
• getLastNumber
• getLastNumberWithSuffix
