My task was to get rid of every Node which has no subnodes of type file at the last level of the hierachy. So for this example the result I needed was an array containing only the nodes 1,2,4,5.
Of course in reality the nested structure was way more complex. My approach was a recursive function which checks every element’s type and nodes length property and calls itself if there are any subnodes. Also it is recommended to loop backwards through the array while deleting from it.

            
            const removeEmptyNodes = nodes => {
                for (let i = nodes.length - 1; i > -1; i--) {
                    const n = nodes[i]
                    //call function recursive to go deeper through the nested structure
                    if (n.nodes) removeEmptyNodes(n.nodes)                        
                    //remove element if it's not a file and has no subnodes
                    if (n.type !== 'file' && (!n.nodes || n.nodes.length === 0)) nodes.splice(i, 1)
                }
            }

            // nodes contains the array data from above
            removeEmptyNodes(nodes)

[SAPUI5] Copy Table Row

 , , , ,

Button für das Kopieren einer Zeile hinzufügen.

<Table id="itemsTable" items="{oModel>/ITEMS}">
<columns>
      <Column id="splitColumn" hAlign="Center" demandPopin="false">
            <Text text="{i18n>SPLIT}"/>
      </Column>
</columns>
<items>
      <ColumnListItem>
            <cells>
                  <Button press="onSplitPressed" id="SPLIT_ROW" icon="{= ${oModel>CUSTOM_ITEM} === true ? 'sap-icon://delete' : 'sap-icon://add'}"/>
            </cells>
      </ColumnListItem>
</items>
</Table>

Nur neu hinzugefügte Zeilen sollen auch wieder gelöscht werden dürfen, daher werden manuell hinzugefügte Zeilen markiert mit CUSTOM_ITEM = True;
Via Expression Binding wird dann das erforderliche Icon bestimmt.

onSplitPressed: function (oEvent) {
		var oContext = oEvent.getSource().getBindingContext("oModel");
		var path = oContext.getPath();
		var oModel = oContext.getModel();
		var oItems = oModel.getProperty("/ITEMS");
		var index = path.substr(path.length - 1);

		//selektiertes Item lesen
		var oItem = oModel.getProperty(path);

		//was soll passieren? Zeile hinzufügen oder entfernen?
		if (oItem.CUSTOM_ITEM !== true) {

			//Neues Item anlegen
			var oNewItem = JSON.parse(JSON.stringify(oItem));
			//Markiere neue Zeile, da nur diese auch wieder gelöscht werden darf
			oNewItem.CUSTOM_ITEM = true;
			// +1 weil Zeile soll ja nach der Aktuellen einfügt werden
			index++; 
			oItems.splice(index, 0, oNewItem);

		} else {
			// Item löschen
			oItems.splice(index, 1);
		}

		oModel.setProperty("/ITEMS", oItems);
	},

Terminal

[Shell] Delete a folder and its content

 , , ,

If you downloaded a series there are often folders for each episode. Each episode folder often includes another folder called “Sample” with a short demo video file.

Series -> Season 01 -> Episode 01 -> Sample -> sample.mkv

To get rid of these you can use the “find” and “rm” command. To remove each sample folder with its content you have to use the remove command with an “-r”.

find -name "Sample" -exec rm -r "{}" \;
