Script / Rename file script
« on: November 08, 2017, 01:10:51 »
Hi.  I couldn't find a way to launch MultiRename profiles on a button or menu, so I wrote a rename script which I am sharing here.  You can duplicate it, tweak it, then put it on a dedicated menu or button.
Pros:
- Can be put on a menu/button
- Can do some things that MultiRename dialog can't (obviously, because it's a programming environment), but it's harder to use.  Once you set it up on buttons though it's all good.
- Works for multiple files selected
- Works in branch view (different paths)

Cons:
- No regex grouping/capture.  So you can't replace (.*) with $1.  This is a big weakness. 
- I couldn't find any StrRegexReplace or any way of knowing how long the match is after StrIsRegExpMatch() returns with a successful find.  I used a messy guess and check iteration to find a match, but it's non-greedy and inflexible.  I'd really like a StrRegexReplace() library function.
- Inefficiency: scRegexExtract(), scRegexDelAfterMatch() and scRegexReplace() only vary slightly.  They should be consolidated into 1 routine.
- No undo.

Notes:
- A popup showing changes is presented giving you the chance to op-out before and filename changes are made.
- Top function MakeNewName() is called once per file.  There are examples in this function (including regex replace, proper case, base reversal, pre/app date).  Uncomment them to try them out.

//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

function MakeNewName($fbase, $fext)
{
   @var $now = GetTime();
   @var $date = FormatDate( "yyyy-MM-dd" , $now );
   @var $seasonepisode;

   // Regex replace base only
   //$fbase= scRegexReplace($fbase, "t.", "AAA", 0);

   // Regex replace global, base only
   //$fbase= scRegexReplaceGlobal($fbase, "(t|T).", "ZZZ", 0);

   // Regex replace, global, case insensitive, base only
   //$fbase= scRegexReplaceGlobal($fbase, ".", "_", 1);

   // Reverse string, base only
   //$fbase = scReverse($fbase);

   // Append date to base
   //$fbase = $fbase + " " + $date;

   // Prepend date to base
   $fbase = $date + " " + $fbase;

   // Regex delete after match case insensitive (base only)
   //$fbase = scRegexDelAfterMatch($fbase, "s[0-9][0-9]e[0-9][0-9]", 1);
   // Proper case base only (Only capitalises.  You need to lowercase first manually.  See examples below)
   //$fbase = scProperCase($fbase);

   // TV Show filename cleanup 1 (Aggresive. Removes episode name and cleans up various things)
   //$fbase= scRegexReplaceGlobal($fbase, "_", " ", 0);
   //$fbase = StrTrim($fbase, " ");
   //$seasonepisode = scRegexExtract($fbase, "s[0-9][0-9]e[0-9][0-9]", 1);
   //$fbase = scRegexDelAfterMatch($fbase, "s[0-9][0-9]e[0-9][0-9]", 1);
   //$fbase = StrToLower($fbase);
   //$fbase = scProperCase($fbase, 7);
   //$fbase = scRegexReplace($fbase, "S[0-9][0-9]e[0-9][0-9]", $seasonepisode, 0);

   // TV Show filename Proper case (Soft. Preserves chars after sXXeXX.  For minor corrections)
   //$fbase = StrToLower($fbase);
   //$seasonepisode = scRegexExtract($fbase, "s[0-9][0-9]e[0-9][0-9]", 1);
   //$fbase = scProperCase($fbase, 0);
   //$fbase = scRegexReplace($fbase, "S[0-9][0-9]e[0-9][0-9]", $seasonepisode, 0);

   // Movie filename cleanup
   //$fbase= scRegexReplaceGlobal($fbase, "_", " ", 0);
   //$fbase= scRegexReplaceGlobal($fbase, "\.", " ", 0);
   //$fbase = scRegexDelAfterMatch($fbase, " (hd|dvd|br)rip", 1);
   //$fbase= scRegexReplaceGlobal($fbase, " (hd|dvd|br)rip", "", 1);
   //$fbase = scProperCase($fbase, 0);

Hi,
Any way to do this?  I have a few favorite profiles that I call regularly.  As a workaround, if I script my own rename sequence, can I put that on a toolbar button?  How about on a custom menu if I create say a RenameProfiles menu?
thanks,
SpiroC
