Abstract: A compositional or alternate object model is employed over an imperative object model to facilitate inspection and construction of imperative structures in a user-friendly manner. Transformations between compositional and imperative models and vice versa can be specified to provide a bridge between differing computing worlds. Moreover, various architectures and/or design patterns can be employed to effect transformation in different ways.

Abstract: Compositional program content is compiled to statements of an imperative application interface in manners that optimize execution and/or resource utilization, among other things. In one instance, a constructor is employed in a manner that obviates a need for extensive memory allocation and parameter copying. Names and namespaces are also cached to avoid expensive table lookup, and redundant namespace declarations are removed and/or moved statically and/or dynamically.

Abstract: A batch compiler is employed to enable compilation of code provided at runtime. A managed application receives code during execution and invokes the compiler to transform the code to enable it to execute within the context of the receiving application. Among other things, employment of a batch compiler preserves investments made to such compilers while also opening up new scenarios in application scripting and/or hosting that are otherwise unavailable.

Abstract: White space is made visible in a code editor to facilitate identification thereof via color, symbols, characters and/or the like. Further, white space can be explicitly identified and distinctly presented of various types including significant, insignificant and editor introduced. White space information can also be employed to aid code compilation and/or processing.

Abstract: When a user enters text into an application, the application can utilize an auto-complete feature to provide the user with estimations as to a complete term a user is attempting to enter into the application. Visualization can be provided along with an estimation to disclose the likelihood the estimation is what the user intends to enter. Furthermore, a rationale can be provided to the user for the reason an estimation was provided to the user.

Abstract: Intelligent assistance functionality is provided in development environments and/or other editors for schematized data. Input of a trigger character sequence can initiate an intelligent assistance box having data corresponding to a related schema. Thus, the intelligent assistance data can be dynamic as schematized data can change; the data can be queried from the schema as requested to facilitate this end. In one embodiment, the data can be an extensible markup language (XML) schema having a plurality of elements. In this regard, syntax can be entered into a development environment to effectuate an intelligent assistance box comprising the elements of the schema; a root level element can be displayed for an initial trigger character sequence. After selecting the element, another trigger sequence can be input to facilitate querying the schema for next level elements, and so on.

Abstract: This disclosure pertains to the interaction between query expressions and metadata. Metadata, for example provided by one or more schemas, can supply information over a domain to be queried and/or navigated. This metadata can be applied to the query expression, or vice versa, to return information about the domain and/or the query expression.
