D : New entrant in Systems Software Arena

Image
In the history of computing C language appeared in 1972 with the humble start for writing portable Operating System kernel (UNIX) C. On the wings of Unix success, C reached far and wide to be used from embedded systems to supercomputers. It went onto succeed in both system software and application software. Soon it was being used for projects huge in size (Lines of code) and complexity started to loom over such projects. Only highly disciplined programmers and process kept large projects going while others started to failed. The symptoms of failure were - missing project timelines, huge delay in bug fixes etc. With appearance of C++ on computing scene (1983) Object Oriented Programming features became available and raised this project size limits to higher levels. C++ added more design and structure to programs and enabled programmers to succeed in big projects with lesser effort. Further increases in complexity of projects have brought virtual machine based platforms like (Java and .N...

Reading Source Code : Best tools available

I explored this GUI wrapper for cscope. I am using it to read Linux kernel sources. The tools looks very promising. It has useful features like : 1. all cscope operations 2. Concept of project open/close etc, file/folder selection 3. Call graph and navigation 4. Multi-color syntax highlight It can open a chosen file in any editor - vim, kate etc. See a snapshot below. [Click on the picture to enlarge] Pros: Memory consumption is low and speed is good. Folding- code, comment, function. Bookmarks Its free and open source. Cons: The two features I found missing (compared to SourceInsight(windows only)) are: - rich coloring of syntax (global / local symbols), - zero effort navigation (automatic preview of symbol definition, easy jump to symbol in another window). - catching duplicate symbols definition/declarations etc. Its the best tool on Linux. For windows I find SourceInsight good option(available for 30-day trial). Reading source ...
