I think I might need to bite the bullet and learn RegEx

I'm working on a rename expression for TV series, and I'm stuck trying to work out a way to handle video files with multiple episodes.

[Series]=Lost
[Season]=6
[Episode]=1-2   (ie double episode)
[Name]=Episode Name  (can't remember)

I'd like an output of Lost - s06e01-e02 - Episode Name.mkv
  (ie individual episodes padded out to 2 digits each and separated by a hyphen and an e-)

MC pads out Season and normal Episode numbers to 2 digits, which is nice.

In this case, I'm having trouble:
  - splitting the '1' and the '2' to put a '-e' between them
  - turning the '1' into '01' and the '2' into '02'

I did some pottering with the Pad and Mid(...) functions but got lost because I was trying to refer to an element within the expression and not a field itself...

If any kind souls have a solution I'd be very happy

You can use ListItem(), but it is more cumbersome since ListItem() doesn't manage degenerate list cases well (eg. single item lists).

RegEx([Episode], /#^(\d+)(?:-(\d+))?$#/, -1)[Series] - sPadNumber([Season],2) ePadNumber([R1],2)IfElse(!isempty([R2]),-ePadNumber([R2],2)) - [Name]

The above runs the RegEx() to capture the 1 or 2 episode numbers, and outputs the string as you want.  It has to test for a possible empty second series value to skip outputting a useless dash after the first episode.

Edit: added missing optional quantifier ?

Thanks MrC!

The above runs the RegEx() to capture the 1 or 2 episode numbers, and outputs the string as you want.  It has to test for a possible empty second series value to skip outputting a useless dash after the first episode.

It is working perfectly on files with multiple episodes separated by a hyphen.
When I run the expression above, however, if [Episode] only contains 1 digit (ie [Episode]=3) I get an output like
   Stargate Atlantis - s01 e00 - Hide and Seek

I know how to use MCs expression language to say 'if episode contains a hyphen do this, else do this' so I can do it that way, but is there a way with RegEx or have I fudged it up?

[MrC]

Silly Me.  I forgot a ? in the pasted RE:

RegEx([Episode], /#^(\d+)(?:-(\d+))?$#/, -1)[Series] - sPadNumber([Season],2) ePadNumber([R1],2)IfElse(!isempty([R2]),-ePadNumber([R2],2)) - [Name]

[MrC]

And here's the explanation of the RE portion:

  ^(\d+)(?:-(\d+))?$

^	Match from beginning of string (your [Episode])
(\d+)	match 1 or more digits, and remember them - capture 1
(?:	start of a cloister group
(\d+)	match 1 or more digits, and remember them - capture 2
)	end of the cloister group
?	The previous atom (here, the cloister group) is optional
$	Match must now be at end of string

[Woops I'm sorry I directed my thanks to EpF and not MrC in my last post as I was reading a post on another thread. I'm a bit scatterbrained this morning! - post amended]

Thanks so much for that MrC. This works flawlessly.

I think I'm starting to wrap my head around the language a bit better. There's a lot of flexibility here with a bit of time investment!
MC has made some great steps with automating import, processing metadata and renaming and moving the files.

No problem, heck I posted a response into the wrong thread today.

Glad to hear its working for you. Cheers.
