Fixed recursive property null reference problems
Fixed issue with node having no children and property check crashing
Made DynamicXml behave more consistently based on user feedback
Added IsNull and HasValue to PropertyResult (comes back from GetProperty but you may need to cast it)
Added new Model.IsNull(string alias, bool recursive) and Model.HasValue(string alias, bool recursive) and Model.IsNull(string alias) and Model.HasValue(string alias)
Added new IsHelper methods for IsModZero, IsNotModZero, IsPosition, IsNotPosition, IsNotFirst, IsNotLast
Added .Count to DynamicXML
Fixed Media .Url and .NiceUrl to bring back umbracoFile
Moved MediaById and NodeById implementations to RazorLibraryCore and deprecated original methods with redirection
Fixed parsing issue with ExamineBackedMedia XPathNodeIterator cast method
Added bool IsHelper(Func<DynamicNode,bool>), string IsHelper(Func<DynamicNode,bool>, string valueIfTrue), string IsHelper(Func<DynamicNode,bool>, string valueIfTrue, string valueIfFlase)
Added IsFirst/IsLast/IsOdd/IsEven helpers for checking position in current context/list
Added IsEqual for checking if the current node matches another by Id
Added IsDescendant/IsDescendantOrSelf/IsAncestor/IsAncestorOrSelf for checking relationships between two nodes
**Breaking Change: DynamicNull.HasValue and DynamicNull.IsNull have been changed from properties to methods
Rename umbraco.MacroEngines.ExtensionMethods as umbraco.MacroEngines.PrivateExtensionMethods
Implement extension method invokes for DynamicNode
.HasProperty will check for a property existence but because the child types are returned as DynamicNull, you couldn't check for null equality.
Use DynamicNull's .IsNull (true) or .HasValue (false) or .Count() (0) or a typeof check
overloads are .Sibling(int) [which you can pass negative to and is equivilent to .Previous(+int) ] or .Sibling(string) which checks nodeTypeAlias
.Sibling(string) will start walking forward at the current node and then wrap back to 0 until it reaches the starting point again
Expression Tree in DynamicQueryable explictly checks for this type and forces that portion of the predicate/expression tree to return true, bypassing the missing property
Handy when you are checking e.g. a boolean property in a .Where and that boolean doesn't exist on all nodes.
Properties from Richtext editor isn't encoded by razor anymore as DynamicNode will return an IHtmlString for RTE properties
Changed the lookups of Yes/no and tinmce datatypes ids to consts as these won't change anyway
Moved Extension Method searching code to seperate static class
Moved all the defined extension methods for DynamicNode into the same ExtensionMethods.cs file
Changed the way that .ContainsAny within a where is evaluated to use the ExtensionMethodFinder class - should allow extra search methods to be defined
Intended as a future extensibility point, provides a way for the parser to redirect into a static method library of helpers
Currently, only one method is available - ContainsAny
Functions like string.Contains but uses needles from a List<string>
var values = new Dictionary<string,object>();
var keywords = new List<string>();
keywords.Add("Five");
keywords.Add("Four");
values.Add("keywords",keywords);
var items = @Model.Children.Where("Name.ContainsAny(keywords)", values);
Allows this syntax to work now:
@Model.Children.Where("updateDate < DateTime.Now.AddDays(-2)")
This didn't work previously in 4.7beta because updateDate was still boxed as an object and object < DateTime can't be implicitly converted
@Model.Children.Where("bodyText.Contains('ipsum')") still doesn't work because the parser doesn't know how to invoke .Contains on a LambdaExpression (yet)
DynamicNodeWalker is our secret weapon in the fight against the Rebel XSLT Alliance
Navigate nodes by calling Up(), Down(), Next() and Previous() on them
Next(1) will jump two items along within the current list, whereas Next() will walk by one within the list
Previous(1) will move two items backwards within the current list
Up() is a special wrapper around .Parent which has an overload .Up(int) to replace @Model.Parent.Parent.Parent... [.Up(2)]
Down() will take you to the first Child item and is equivilent to .Children.First(), use .Down(1) to replace .Children.First().Children
If one of the NodeWalker functions fails to find a node at the requested position, it will return null
