BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 illustrates a block diagram of two stages of software development.
FIG. 3 illustrates a flow diagram that includes a method for identifying dependencies in code and retrieving the dependencies prior to compiling and/or running the program.



DETAILED DESCRIPTION
As discussed above, in software development, after source code is written the source code may be compiled during a compiling stage of development. Following the compiling of the source code, the program may be run during a run stage of development.
Prior to compiling source code during the source code compiling stage of development, some compilers may need access to compile stage dependencies such as, libraries, files, or other infrastructure in order to properly compile the source code.
After the source code is complied, when the program is run (during the run stage), run stage dependencies may be needed by the program to run. Run stage dependencies include, for example, use of a database library, advanced message queuing protocol, or a message service.
For a developer who, for example, is using open-source source code, determining what compile stage and run stage dependencies that are needed to effectively compile and run the program can be burdensome. The methods and systems described herein provide for heuristically analyzing the source code to determine if any compile stage dependencies exist and/or any run stage dependencies exits. If dependencies exist, the method and system is operative to retrieve the dependencies to facilitate compiling and running the code.
FIG. 1 illustrates an exemplary embodiment of a processing system 100. The system 100 includes a processor 102 that is communicatively connected to a memory 104, a display 106, an input device 108, and a network 110. The methods described herein may be performed by the system 100.
FIG. 2 illustrates a block diagram of two stages of software development. In this regard, a compiler 206 during the compile stage receives source code 202. During compiling, the compiler 206 receives, retrieves, accesses, or stored compile stage dependencies 204, which facilitate compiling the source code 202.
After the source code 202 has been compiled, the program 208 may be run during the run stage. To run properly, the run stage dependencies 210 are retrieved, accessed, received, or stored by the program 208 when the program runs.
FIG. 3 illustrates a flow diagram that includes a method for identifying dependencies in code and retrieving the dependencies prior to compiling and/or running the program. In block 302 the source code is received by the processor 102 (of FIG. 1). In block 304, the source code data set is opened and scanned to identify compile stage dependencies (CSD) and run stage dependencies (RSD). The CSDs may be identified by, for example, scanning the code to identify header/include files and checking to ensure that the files or libraries associated with the header/include files are present. The system may also identify declaration of variables that use the identified classes. A RSD may be identified once a CSD is found. The program has a database that identifies the common libraries and what the common libraries are used for. The program may search through the CSDs looking for libraries that use a run-time infrastructure such as, for example, databases or messaging que systems. For example, if a CSD scan identifies a declaration for a JAVA database connectivity (JDBC) handler, the program will retrieve the libraries used by the JDBC handler. The RSD scan will check the system database and determine that the JDBC is used for databases. The RSD will allocate a database server for the user.
In block 306, the processor 102 determines whether any compile stage dependencies have been identified. If yes, the processor 102 determines whether the identified compile stage dependencies are present or available or accessible for the compiler in block 308. If no, the processor 102 retrieves or identifies addresses or other access information for the identified compile stage dependencies in block 310. In block 312, the processor 102 determines whether any run stage dependencies have been identified. If no, the processor 102 compiles and saves the compiled code in block 314. If yes, in block 316, the processor 102 determines whether the identified run stage dependencies are present or available or accessible for running the compiled program. If no, the processor 102 presents a list of the run stage dependencies to the user in block 318. If the user desires to both compile and run the program, the user may choose to enter an input indicating what run stage dependencies that the user would like the processor 102 to retrieve prior to running the program in block 320. In block 322, the processor 102 compiles and saves the code. In block 324 the processor 102 (or another processor) may run the program. The processor 102 may output to a user a summary of the retrieved compile stage dependencies and the retrieved run stage dependencies. The summary may include, for example, credentials, internet protocol addresses or other information that may be useful to the user for further development or integration of the program.
In some programs, run stage dependencies may include a database or other data structures to properly run the program during the run stage. In this regard, the processor 102 may identify such run stage dependencies (as shown in block 312 of FIG. 3). The processor 102 is operative to determine the database requirements for running the code, and in some embodiments, provision or request the generation of a database or other data structure that may be present on server and accessible via a network.
In this regard, the processor 102 may determine the parameters of the database that is identified as a run time dependency and generate a database or file structure that satisfies the run stage dependency. This run time dependency may be present on the system 100 (of FIG. 1) or externally via a cloud based or server based service. When deploying remotely, the program will change its configuration files to match the locations of the dependencies. For example, if a database is deployed onto a cloud system, the local system will need to know the location of the database as well as username and password credentials that are used to access the database. The program updates the configuration files for the project.
The methods and systems described herein provide for identifying compile stage dependencies and run stage dependencies in source code and retrieving or generating the dependencies to effectively compile and run the code.

In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
