Method and system for presenting and analyzing software source code through intermediate representation
The present invention provides a method and system for producing intermediate representation of source code listings with possibly mixed syntaxes to assist software development applications in presenting and analyzing the source code listings through reading the intermediate representation. A source code processor calls Application Programming Interfaces (APIs) to preserve source code information, which includes intermediate representation data sets and is preferably stored in a file-based repository. The source code processor is of a compiler, a preprocessor, a parser, or a comment document processor. The data sets capture lexical, syntax and semantic information of source code construct elements, and comprise of location, processor identification, construct category, and attribute data. A software development environment through a source code search engine is able to present source code construct elements, outlines, and symbol references from software packages over a plurality of distributed servers in a network such as the Internet.

generating a derived source code information in a predetermined data format using the subset of the plurality of SIR data sets, and the listing identifier;
saving the derived source code information into the data storage;
receiving a search request with search criteria comprising a symbol of the source code listing;
outputting a search result comprising the symbol with a reference link using the derived source code information stored in the data storage; and
delivering the search result in response to the search request.
