Cscope is a text screen based source browsing tool. Although it is primarily designed to search C code (including lex and yacc files), it can also be used for C++ code.

Using cscope, you can easily search for where symbols are used and defined.

Beautify source code in many languages of the C family (C, C++, C#, Objective C, D, Java, Pawn, and Vala). Features:

• Indent and align code.

• Reformat comments (a little bit).

• Fix inter-character spacing.

• Add or remove parens / braces.

• Supports embedded SQL EXEC SQL stuff.

• Highly configurable - More than 600 configurable options.

GNU GLOBAL is a source code tagging system that functions in the same way across a wide array of environments, such as different text editors, shells and web browsers. The resulting tags are useful for quickly moving around in a large, deeply nested project.

scc provides a lines-of-code counter similar to tools like cloc and sloccount. It aims to be fast as possible while supporting COCOMO calculation and code complexity estimation.

Sourcetrail is a free and open-source cross-platform source explorer that helps you get productive on unfamiliar source code. It includes support for C/C++, providing a graphical means for discovering symbols and their place in a project.

cloc counts blank lines, comment lines, and physical lines of source code in many programming languages. Given two versions of a code base, cloc can compute differences in blank, comment, and source lines.

cloc contains code from David Wheeler's SLOCCount. Compared to SLOCCount, cloc can handle a greater variety of programming languages.

Xenon is a monitoring tool based on Radon. It monitors code complexity. Ideally, xenon is run every time code is committed. Through command line options, various thresholds can be set for the complexity of code. It will fail (i.e., it will exit with a non-zero exit code) when any of these requirements is not met.

The Automatic Component Toolkit (ACT) is a code generator that takes an instance of an Interface Description Language (IDL) file and generates a thin C89-API, implementation stubs, and language bindings of your desired software component.

Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C++/CLI, Objective‑C, C#, and Java programming languages.

Indent is a program that makes source code easier to read by reformatting it in a consistent style. It can change the style to one of several different styles such as GNU, BSD or K&R. It has some flexibility to deal with incomplete or malformed syntax. GNU indent offers several extensions over the standard utility.

Kcov is a code coverage tester for compiled languages, Python and Bash. It was originally a fork of Bcov, but has since evolved to support a large feature set in addition to that of Bcov.

Kcov uses DWARF debugging information for compiled programs to make it possible to collect coverage information without special compiler switches.

GNU cflow analyzes C source files and produces a graph charting the control flow of the program. It can output the graph in several styles and in either the POSIX format or in an extended GNU format. cflow also includes a major mode for Emacs for examining the flowcharts that it produces.

Universal Ctags generates an index (or tag) file of language objects found in source files for many popular programming languages. This index makes it easy for text editors and other tools to locate the indexed items. Universal Ctags improves on traditional ctags because of its multilanguage support, its ability for the user to define new languages searched by regular expressions, and its ability to generate emacs-style TAGS files.

This package provides a complete GCC tool chain for C/C++ development to be installed in user profiles. This includes GCC, as well as libc (headers and binaries, plus debugging symbols in the debug output), and Binutils. GCC is the GNU Compiler Collection.
