of the JDT platform AST for any selected class or method. Today's VS Code tip: Call hierarchy Explore the callers of a given function of method, or view which functions that function itself calls VS. using the JDT platform Search and Call Hierarchy mechanisms. Also enables exploration of extended class inheritance hierarchies. As we know Doxygen is a very powerful tool to do documentation, but it’s more geared toward object-oriented languages like C++ and Java. Enables graphical analysis of program call relations and flow sequencing. You'll want to tweak that XSLT and then partition that directed graph in the way that cuts across the fewest edges. Provides Call-Path and Sequence Diagram viewers. Which gives you a line per caller-callee like this: main calls svn_error_t * init_apr(apr_pool_t **ppool, int *argc, char const *const **argv) I've inhereted C code for a major project at work which has been commented using Doxygen style, and don't have contact with the old programmer. So for every memberdef/referencedby pair, you have a caller-callee relationship, which you can grab via XSLT: Configuring Doxygen to draw a custom graph on: June 19, 2015, 11:30:36 am Hi Guys, I'm hoping someone here knows a bit about Doxygen. (apr_pool_t **ppool, int *argc, char const *const **argv) For each function marked with the callergraph, you'll find elements in the output that you can use. I'm not obsessed by this being a graphical solution - I'd be quite happy if someone could suggest an alternative analysis tool (free or relatively cheap) or technique using Doxygen's XML output to achieve the same goal.Ī callergraph amalgamated at the file level does have a certain appeal for client documentation rather than a plain list :-)Īnd then you can find your call graph in the XML files. I'm considering writing some kind of DOT merge tool - setting DOT_CLEANUP=NO makes Doxygen leave the intermediate DOT files there rather then just retaining the png files they generated. There are hundreds of functions so simple inspection of the generated callergraphs is painful. The original header files are no use - they expose everything as untyped C functions. What I'd like to do beyond that is amalgamate these graphs so I can determine the narrowest boundary of functions exposed to the outside world. I've marked up the key source files with the Doxygen markup so informative graphs are generated for individual functions. I need to move some files into a pure DLL and determine the minimal interface to make public, which is going to require wrapper functions writing to publish a typed interface. I've already abandoned an attempt to convert these to ANSI declarations due to nested use of function parameters (just couldn't get those last 4 compiler errors to go). This is complicated by the heavily recursive mathematical core code being K&R style declarations. doxygen will generate a call dependency graph for every global function or. I have a collection of legacy C code which I'm refactoring to split the C computational code from the GUI. a/doc/nf Fri Oct 26 22:11:48 2007 +0200 +++ b/doc/nf.
