Abstract: Disclosed are embodiments a computer-implemented method, a system and an associated program storage device that provide for automatic programming language grammar partitioning to solve the “code too large” problem. The embodiments partition a particular programming language grammar into logical subsets based on a set of partitioning heuristics and using a dependency graph that is preprocessed so as to be devoid of any cyclically connected grammar rule nodes. For each logical subset, textual code for a corresponding portion of a parsing program can be generated and then converted into machine-readable code for that corresponding portion of the parsing program. Thus, small amounts of textual code for portions of a parsing program are discretely converted into machine-readable code, thereby avoiding the “code too large” problem. The machine-readable code for all portions of the parsing program can then be merged and the parsing program can be executed in order to parse a corpus.

The implementation includes a second data structure and implementation rules which define the syntax rules of the first data structure to be enforced in relation to nodes of the second data structure during a subsequent processing operation which utilizes the implementation in order to establish compliance with the syntax rules represented by the first data structure. Links between nodes of the first data structure are representative of paths of inheritance of substitutability but not implementation and interface between those nodes.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for selecting a first grammar rule in a programming language grammar. The grammar is used for determining a syntax validity of a programming code statement in a text editor and the first grammar rule includes a hard-to-type symbol that is syntactically correct for the programming code statement. A second grammar rule for the grammar is created. The created second grammar rule is substantially identical to the first grammar rule but the hard-to-type symbol is replaced with an easy-to-type symbol that is syntactically incorrect for the programming code statement. An action is associated with the grammar and is performed upon satisfying the second grammar rule. Performance of the second grammar rule causes the easy-to-type symbol in the programming code statement in the text editor to be replaced with the hard-to-type symbol.

Abstract: There is described a method of compiling source code for a computer program into corresponding object code. The source code includes several declared variables. The method comprises, for each declared variable in the source code, including in the object code a declaration statement indicating an associated memory location for that variable and indicating the position in the object code of the next declaration statement. During compilation, the memory location for each declared variable can be retrieved from the object code by examining each declaration statement in turn, using the position information from each declaration statement to locate the next declaration statement. This is of particular advantage where the available volatile memory is limited, because there is no requirement for a look-up table of variables against memory locations.

Abstract: In many messaging systems, message selection filtering involves a significant processing overhead. This includes the parsing and preparing of the message selection filters in readiness for evaluation, as well as the evaluation itself. In systems which involve parsing and prepare processing for expressions that include repeated patterns (such as in many JMS environments), a template-based shortcutting of the conventional processing improves performance. A stored parsing template is used to parse an input sequence such as a received data processing instruction. The parse is used to identify expressions of a first type that can then be implicitly optimized by using a stored evaluation template that is associated with expressions of that type.

This object is achieved according to the invention by a method for editing source code, the method comprising the steps of: receiving a modification to the source code, said modification being made by a user, determining whether the modification would change the semantics of the source code, and handling the modification depending on the result of the determining step.

Abstract: Client Native method Interface (CNI) minimizing eXtensible Mark-up Language (XML) parsing is provided using array pair data structures. An empty array pair is passed to an engine from client code via a CNI call. The engine parses the XML document and fills the array pair with fixed width elements. The filled array pair is passed back to client code. The client code iterates through the elements in the array pair and invokes the appropriate handlers or builds appropriate tree objects for Document Object Model parsing. Thus, one CNI call passes the empty array pair from client code to the engine, and the filled array pair is returned from the engine to client code. Individual sets of CNI calls for each element are avoided, minimizing the number of CNI calls. Further, since elements in the array pair are of fixed width, they can be processed more efficiently by the client code.

The command line is parsed at said client using said selected rule set. If parsing did not result in a syntax error, a command request is sent from said client to said target. In response, the client receives a command response including information regarding a version of syntax rules currently used on said target.

Abstract: A system and method provide the ability to construct lexical analyzers on the fly in an efficient and pervasive manner. The system and method split the table describing the automata into two distinct tables and splits the lexical analyzer into two phases, one for each table. The two phases consist of a single transition algorithm and a range transition algorithm, both of which are table driven and permit the dynamic modification of those tables during operation. A third ‘entry point’ table may also be used to speed up the process of finding the first table element from state 0 for any given input character.

Abstract: Declarations from an input source code or tokenized source code are serialized into a stream of tokens produced by following each branch of a preprocessor conditional directive statement that interrupts a declaration. Tokens are labeled with a parsing path indicator corresponding to a parsing path induced by branches of a preprocessor conditional directive. The declarations that are formed along the different parsing paths are serialized by fetching the tokens that belong to the first parsing path in a first pass, and passing the tokens on to a next phase of a compiler. The pointer that marks the next token is repositioned to return to the start of the declaration. The declaration may be serialized again through the second parsing path in a second pass. The operation may be repeated until each of the parsing paths induced by the presence of branches of the preprocessor conditional directives in the source code is exhausted.

Abstract: When writing code, data structures that include inferred symbols are created based on usage of undefined symbols. As the user continues writing code, code model can be updated to represent updated information based on a learning model. Data structures including inferred symbols can be used by software development tools to provide developer help for symbols that are not yet created or are not yet bound. Inferred symbols can be visually distinguishable making the appearance of the inferred symbol information differ from actual symbol information. The appearance of information based on inferred symbols can be included within tools by activating a particular mode in a programming environment. Conversion of the inferred symbol to a real symbol may trigger the automatic compiler-generation of additional source code by a background compiler. Inferred symbols may be converted to actual symbols by activation of an option to make an inferred symbol a real symbol.
