This will show you how to take an LFP and create issue tags at every boundary break.
Additional info: http://www.regular-expressions.info/
Details of Search: ^IM,(.*?),([a-z]),(.*)$
^ – this is an anchor it tells the parser to start at beginning of a line
IM, – common text that will be found on all matches in this example (commas used outside of capture groups again to help anchor)
(.*?), – the round brackets are the 1st capture group that can be backreferenced in the search as
well as the replacement
– the dot is a wild card that will match anything (almost)
– the star (asterisk) tells it to keep matching what’s in front of it (in this case a dot)
– the question mark makes it stop at the first instance of the following character,
in this case a comma. This modifier to the star is called a non-greedy star
([a-z]), – round brackets the 2nd capture group.
-the [a-z] tells to match exactly one letter a thru z
(so spaces, ie non-boundary lines, would not match)
(.*) – round brackets are the 3rd capture group. This is considered a greedy-star and
will match the rest of the line.
$ – this is another anchor it tells the parser to match the end of a line
Details of Replacement:
The captured groups are referenced in the replacement as \<number>
In this case \1, \2, and \3.
So IM,\1,\2,\3 simply replaces what was already there
And IS,\1,HelloWorld adds a new line with HelloWorld issue tag
