Abstract: Creating metadata for dynamic code in a descriptive metadata language. The method includes obtaining one or more first data structures defining constructs in a body of dynamic language source code. From the one or more first data structures, identifier information is extracted for one or more of the defined constructs. Knowledge about the constructs is augmented. Metadata about the body of the dynamic language source code is provided, with the source code, in a specific metadata format, to a user.

Abstract: Various embodiments provide an ability to describe, independent of a programming language, one or more interfaces associated with an operating system. Alternately or additionally, a compiler associated with a specific programming language can be configured to map the independent interface description(s) to the specific programming language. In some embodiments, an application can be configured to programmatically determine one or more interfaces of the operating system.

Abstract: Various embodiments provide an interface between a Web browser's layout engine and a scripting engine. The interface enables objects from the layout engine to be recognized by a memory manager in the scripting engine and interact in a streamlined, efficient manner. In accordance with one or more embodiments, the interface allows browser layout engine objects to be created as objects that are native to the scripting engine. Alternately or additionally, in some embodiments, the native objects are further configured to proxy functionality between the layout engine and the scripting engine.

Abstract: Aspects of the subject matter described herein relate to generating and caching software code. In aspects, a target device may receive software to install. The software may include source code that has not been compiled. The target device may install the software and indicate the source code of the package is to be compiled into intermediate or executable code that is persistently stored. If the target device receives a request to execute the software prior to it being compiled, the target device may compile and execute the software without delay. If the target device receives a request to execute the software after it is compiled, the target device may obtain and execute the compiled code. The behavior above may also be applied to scripting code obtained from a server remote to the target device.

Abstract: An object reference is tagged with an isolation permission modifier. At least two permissions can be included, and in an example three permissions are included. In implementing the permissions, type modifiers for controlling access to type members through references pointing at an object are defined. One of the type modifiers is associated with each occurrence of a type name. Each of the of type modifiers defines a different access permission to restrict operations on the object to which the reference points.

Abstract: Enhancing dynamic code. A method includes obtaining one or more first data structures defining constructs in a body of dynamic language source code. From the one or more first data structures, identifier information is extracted for one or more of the defined constructs. Knowledge about the constructs is augmented. Using the identifier information and augmented knowledge, metadata about the body of the dynamic language source code is generated. The generated metadata is represented as a symbol table. The body of dynamic language source code is visually enhanced based on the symbol table structure.

Abstract: Creating metadata for dynamic code in a descriptive metadata language. The method includes obtaining one or more first data structures defining constructs in a body of dynamic language source code. From the one or more first data structures, identifier information is extracted for one or more of the defined constructs. Knowledge about the constructs is augmented. Metadata about the body of the dynamic language source code is provided, with the source code, in a specific metadata format, to a user.

Abstract: A method disclosed herein includes acts of receiving code at a Just-in-Time compiler executing in an application on a computing device and compiling the code to generate machine code and causing the machine code to be placed on at least one page that is accessible by at least one processor on the computing device, wherein the Just-in-Time compiler compiles the code utilizing at least one technique for preventing a Just-in-Time spraying attack.

Abstract: A method, system, and computer product for processing information embedded in a text file with a grammar programming language is provided. A text file is parsed according to a set of rules and candidate textual shapes corresponding to potential interpretations of the text file are provided by compiling a script. An output is provided, which may include either a processed value corresponding to a particular textual shape, or a textual representation of the text file that includes generic data structures that facilitate providing any of the candidate textual shapes, where the generic data structures are a function of the set of rules.
