Incremental Save ESTK

Postby h4unt3r » Tue Jun 04, 2013 9:47 pm

Hey guys, I'm very new to photoshop scripting but I have a fair bit of experience with OOP in javascript (client side and nodejs) also I have a bit of experience with maxscript (weep those who know it). So recently where i work someone asked for an incremental save script so here it is in its blazing beta glory! Some things might not work, I haven't been able to spend too much time on it, hope you can use / learn from it

Code: Select allfunction zeroPad ( num, digit ){
   if( num < 10 ) return "00"+num;
   if( num < 100 ) return "0"+num;
   return num;
}

function basename( str ){
   var regex = /(.*)\.[^\.]+/
   var match = str.match( regex ) ? str.match( regex ) : [ str, str, undefined ];
   return match[1];
}

function SaveIncrement()
{
   try {
      activeDocument;
   }catch( err ){
      alert( "You must haved saved the document to save a version." );
      return;
   }
   // Properties
   this.file = new File( decodeURI( activeDocument.name ) );
   this.folder = new Folder( activeDocument.path );
   this.basename = basename( this.file.name );

   // Basic options
   this.defaultExt = 'psd';
   this.suffixStart = '_';
   this.suffixLenght = 3;
   // Save options
   this.opts = new PhotoshopSaveOptions();
   this.opts.embedColorProfile = true;
   this.opts.alphaChannels = true;
   this.opts.layers = true;

   // Get the next unused increment
   this.nextIncrement = function( basename ){
      var regex = '.+?'+this.suffixStart+'(\\d+).*';
      var increments = this.folder.getFiles( basename+this.suffixStart+'*.'+this.defaultExt );
      var nextIncrement = 0;
      for( var i=0; i < increments.length; i++ )
      {
         var increment;
         var match = increments.name.match( regex );
         if( !match || isNaN( Number( match[1] ) ) )
            continue;
         increment = Number( match[1] );
         if( !isNaN( increment ) )
            nextIncrement = increment > nextIncrement ? increment : nextIncrement;
      }
      nextIncrement++;
      return nextIncrement;
   }

   // Save the file as the next increment
   this.saveIncrement = function( increment ){
      if( increment == undefined )
         increment = this.nextIncrement( this.basename );
      var saveFile = new File( this.folder+'/'+this.basename+this.suffixStart+zeroPad( increment, this.suffixLength )+'.'+this.defaultExt );
      activeDocument.saveAs( saveFile, this.opts, true, Extension.LOWERCASE );
      if( saveFile.exists )
         return true;
      return false;
   }

   // Create the ui and show it
   this.show = function(){
      var t = this;
      dlg = new Window( 'dialog', 'Save Increment' );

      // Set dialog color
      var brush = dlg.graphics.newBrush( dlg.graphics.BrushType.THEME_COLOR, 'appDialogBackground' );
      dlg.graphics.backgroundColor = brush;
      dlg.graphics.diabledBackgroundColor = brush;

         if( selFolder != null ){
            dlg.uiDestinationTXT.text = selFolder.fsName;
            t.folder = new Folder( selFolder );

si = new SaveIncrement();
si.show();
