PyChecker is a tool for finding common bugs in Python source code. It finds problems that are typically caught by a compiler (or lint) for less dynamic languages, like C and C++. Common errors that can be found include forgetting to import a module, misspelling a variable, passing the wrong number of parameters to a function/method, and not using a module/variable.
Clint is a test bed for static source code checking, designed to check C++. It is designed to detect common programming errors and warn the programmer about these errors. It can warn you about errors or potential problems like header files not being protected. It is very extendible and has a Python plugin so you can write rules in Python.
Steel Bank Common Lisp is a development environment for Common Lisp, with excellent support for the ANSI standard: garbage collection, lexical closures, powerful macros, strong dynamic typing, incremental compilation, and the famous Common Lisp Object System (multimethods and all). It also includes many extensions, such as native threads, socket support, a statistical profiler, programmable streams, and more. These are all available through an integrated, interactive native compiler which feels like an interpreter. SBCL is unique in being a multiplatform native compiler which bootstraps itself completely from source, using a C compiler and any other ANSI Common Lisp implementation.
Kelly is a JBuilder 4 & 5 plugin that makes it easy to deploy EJBs to JOnAS 2.x. Kelly can be installed and run with other JBuilder 4 & 5 plugins such as BEA WebLogicServer 5.1, BEA WLS 6, IBM WebSphere 3.5, Borland AS 4.5, etc. Kelly provides services to Jbuilder 4 & 5 java developers such as the ability to create any XML deployment files required by JOnAS 2.x, hot loading and unloading of any EJBs to JOnAS (only for JBuilder 5), control of JOnAS start-up from JBuilder 4 & 5, and the supply of JOnAS word dictionaries to JBuilder 4 & 5 in order to enhance the JBuilder 4 & 5 text completion services.
ltrace is a debugging program which runs a specified command until it exits. While the command is executing, ltrace intercepts and records the dynamic library calls which are called by the executed process and the signals received by that process. It can also intercept and print the system calls executed by the program. The program to be traced need not be recompiled for this, so you can use it on binaries for which you don't have the source handy. You should install ltrace if you need a sysadmin tool for tracking the execution of processes.
jLouiss is a shared library for logging of start and return of Java methods together with their parameters and result values. Is is designed as an add-on to the JDKs 1.2, 1.3, and 1.4 by various vendors. The tracer output can be controlled by using regular expressions. jLouiss is designed on the JDK JVMDI interface (older releases used the JIT interface).
