The C Code Analyzer (CCA) is a static analysis tool for detecting potential security problems in C source code. It's fully automatic; no code annotations or the like are required. It features an automatic user input tracer, potential buffer overflow detection, and more. An eclipse frontend plugin is included.
CDuce is a programming language adapted to writing safe and efficient applications that manipulate XML documents. A type system checks at compile time that applications deal with all the possible inputs and produce only valid outputs. Pattern matching is a powerful operation based on regular expressions to inspect documents. CDuce also features general-purpose features; it is a higher-order functional language, with a type-safe interface with Objective Caml.
CIL is a frontend for the C programming language which facilitates program analysis and transformation. CIL will parse and typecheck a program, and compile it into a simplified subset of C. For example, in CIL, all looping constructs are given a single form and expressions have no side effects. This reduces the number of cases which must be considered when manipulating a C program. CIL has been used for a variety of projects, including CCured, a tool which makes C programs memory safe. It supports ANSI C, as well as most of the extensions of the GNU C and Microsoft C compilers. A Perl script acts as a drop-in replacement for either gcc or Microsoft's cl, and allows merging of the source files in your project. Other features include support for control-flow and points-to analyses.
Cameleon is an integrated development environment for Objective Caml and eventually other languages. Its features include a graphical user interface, configuration management based on CVS, easy access to and browsing of documentation, various editors, customizable file types, a plug-in architecture, and a highly customizable interface.
CamlTemplate is a library for generating text from templates in Objective Caml. It can be used to generate Web pages, scripts, SQL queries, XML documents, and other sorts of text files. It provides a versatile, easy-to-learn template syntax that supports common scripting-language constructs, while encouraging a separation between presentation logic and application logic. The supported Caml data structures accomodate lists, tables, and trees of items in a straightforward manner. CamlTemplate works well with mod_caml and mod_fastcgi, supports any ASCII-compatible encoding, including UTF-8, and includes optional support for multithreading.
Felix is a programming language with a fully featured purely functional subsystem embedded in a a traditional Algol-like imperative programming system. The system features garbage collection, static typing, parametric polymorphism, overloading, regular expression matching, and a lot more. A scripting harness is used to invoke source files, but fully compiled binary shared libraries are generated, yielding both rapid prototyping and high performance. Seamless binding of C/C++ code makes interfacing existing libraries easy. Control inversion provides language-level cooperative multi-tasking.
