Cbrowser is a front end to the popular source code indexing and querying program cscope. The cscope code has been released as Open Source by Santa Cruz Operation, Inc. (SCO) under the BSD license.
Development of cbrowser and cscope is now hosted by Sourceforge. This will allow anyone to improve upon this software, and make it usable to a much wider audience. You can get help, or contribute to the development by visiting the project page. Many thanks to the folks at VA-Linux for providing this service.
Both of these tools have text based user interfaces, and have limited file viewing capabilities. Cbrowser provides a full featured source code viewer with syntax highlighing and full text searching. The file viewer can be detached so multiple files can be viewed simultaneously.
Cbrowser helps manage the recursive process of searching through source code by providing a history mechanism. Every query is recorded and can be recalled at any time, without the need of re-querying the database.
Cbrowser allows you to build and use multiple source code databases for individual software projects. Switching databases is as simple as selecting the file, and a history of all databases used is kept at all times.
Best of all, cbrowser provides a hierarchical function call tree. Functions may be expanded and contracted to show or hide the functions they call. The function's code itself is shown in an adjoining viewer. This feature is implemented using the megawidget Library by Jeff Hobbs which luckily for me comes with an unrestricted license.
Cbrowser is implemented in Tcl/Tk. It requires at least Tcl7.6/Tk4.2. It is now primarily tested with Tcl/Tk 8.3, and Tcl/Tk 8.0p2. I found a few minor problems with alpha releases of Tcl 8.0, so I strongly recommend using at least version 8.0p2.
Cbrowser was designed to be used in a UNIX or UNIX-like environment, but it should be usable under Windows if that's what you really want... You may be able to adapt cs to function properly under Windows, but cscope is a UNIX tool only. Primarily cbrowser has been tested on a GNU-Linux x86 PC, but it has also been tested on SPARC Solaris 2.5.1 and x86 Solaris 2.6. There are no specific features of these operating systems used that should require any porting effort to other UNIX OSes or platforms. See Tcl/Tk Platforms for the complete list of supported platforms.
I have chosen to distribute cbrowser under the GNU General Public License (aka "copyleft"). This means you can use it and abuse it as long as you don't try to sell it to someone else as if it were yours.
You can see a tclet demo of the program here. If you don't have the Tcl/Tk plugin go here to get it.
Now without further ado, you can obtain the full source code and executable here:
Cbrowser is distributed as a gzip compressed UNIX tar file. It contains all of the necessary Tcl/Tk source for cbrowser, including the megawidgets provided by Jeff Hobbs. To install, extract the archive into your preferred installation directory, and follow the instructions in the README file.
