Abstract

A method and apparatus are disclosed for enhancing operable functionality of input source code files from a software program by identifying a first code snippet and a first library function which generate similar outputs from a shared input by parsing each and every line of code in a candidate code snippet to generate a templatized code snippet data structure for the first code snippet, and then testing the templatized code snippet data structure against extracted library function information to check for similarity of outputs between the first code snippet and the first library function in response to a shared input so that the developer is presented with a library function recommendation which includes the first code snippet, the first library function, and instructions for replacing the first code snippet with the first library function.

Dependent claims

A method performed by a device having an operating system and a system library for enhancing operable functionality of a software program, the device including a processor and a memory coupled to the processor, wherein the memory includes program instructions stored thereon and the processor executes the instructions to carry out the method, the method comprising:

receiving, by the device, a plurality of input source code files from the software program submitted by a developer;
identifying, by the device, one or more candidate code snippets from the plurality of input source code files;
identifying, by the device, at least a first code snippet and a first library function which generate similar outputs from a shared input by parsing each and every line of code in a candidate code snippet to generate a templatized code snippet data structure for the first code snippet, and then testing the templatized code snippet data structure against extracted library function information to check for similarity of outputs between the first code snippet and the first library function in response to the shared input;
and
presenting, to the developer, a library function recommendation comprising the first code snippet, the first library function, and instructions for replacing the first code snippet with the first library function.

A computer program product comprising at least one recordable medium having stored thereon executable instructions and data which, when executed by at least one processing device, cause the at least one processing device to:

receive a plurality of input source code files from a software program submitted by a developer;
identify one or more candidate code snippets from the plurality of input source code files;
identify at least a first code snippet and a first library function which generate similar outputs from a shared input by parsing each and every line of code in a candidate code snippet to generate a templatized code snippet data structure for the first code snippet, and then testing the templatized code snippet data structure against extracted library function information to check for similarity of outputs between the first code snippet and the first library function in response to the shared input;
and
generate a library function recommendation comprising the first code snippet, the first library function, and instructions for replacing the first code snippet with the first library function.

2 more elements

A system comprising:

one or more processors;
a memory coupled to at least one of the processors, and
a set of instructions stored in the memory and executed by at least one of the processors to enhance operable functionality of a software program by recommending library substitutions for input source code files, wherein the set of instructions are executable to perform actions of:
receiving a plurality of input source code files from the software program submitted by a developer;
identifying one or more candidate code snippets from the plurality of input source code files;
identifying at least a first code snippet and a first library function which generate similar outputs from a shared input by parsing each and every line of code in a candidate code snippet to generate a templatized code snippet data structure for the first code snippet, and then testing the templatized code snippet data structure against extracted library function information to check for similarity of outputs between the first code snippet and the first library function in response to the shared input, and
presenting a library function recommendation comprising the first code snippet, the first library function, and instructions for replacing the first code snippet with the first library function.
