gcc, Recently I have been interested in creating an open source refactoring tool. I did not have much luck finding an application that does what I need and thought that I could get some feedback from the gcc community. In particular I would like to add a flag which would cause gcc to emit symbol definition and use information. The -fdump-* flags provide much of this information in various formats. I would like to combine the salient information into a denser binary format that could be consumed by a subsequent application which would then modify the original source text. I would like this second application to be a command line tool which uses a syntax similar to gdb. For example "show unused headers in test.cpp" would print the header files which were included but not required in test.cpp. I have been able to come up with a small set of functions that I would like to be available, these include: rename [function|class|variable]+ [in scope] old_name new_name //rename a function or variable or class move [function|class|variable]+ to file //move a function class or variable definition to a different source code location remove using [namespace name] from file //fully qualify each symbol use with the appropriate namespace create function from file.begin_line file.end_line //create a function out of a block of code Having spent some time looking at the code for gcc it seems reasonably easy(with some suggestions) to traverse the tree generated and write the relevant information to a file. Any suggestions or pointers to related work would be much appreciated. Patrick
