I have just uploaded a source code for metric analyser for C and C++
to the /pub/Linux/incoming directory on sunsite.unc.edu. The file uploaded
is called cccc-1.00.tgz, and it is a gzip'ed tar file. I hope that it will be
moved into the /pub/Linux/devel/c++ directory within a short period of time.
The analyser implements a very coarse parser, the purpose of which is to
break the source code into high-level chunks like a single function body,
global variable declaration, class declaration or definition etc. All
analysis is then done by simple counting in the lexical analyser.
I recommend it to anyone interested in the topic of software metrics, and
also if you are interested in C++ parsing but don't need a thorough parse.
E.g. reverse engineering applications might be find use for a parser which
takes a similar high-level view and largely ignores the internals of
functions except for keeping a careful count of matching braces, brackets and
parentheses (which help to track when the system returns to outer scope).
The implementation has been done on Linux, although I found it relatively
pain-free to tweak the makefile to compile on DEC OSF/1 v3.2. The program
is heavily dependent on an excellent PD compiler generator toolset called
pccts, provided by a programmer called Terence John Parr and a number of
collaborators, formerly at the University of Minnesota. I have also uploaded
a file called pccts-1.33-linux.tgz which contains the source of pccts with
slightly tweaked makefiles etc. to provide installation and environment
settings consistent with the Linux filesystem standard document.
This work has been done to support my thesis studies for an M.Sc., and if
you retrieve the source package, you will find details of the subject of
the study, and an appeal for industry sites willing to participate in my
research.
best wishes, and thanks to TJP and his collaborators for a great tool
