This module, when enabled, registers a handler for certain types of fatal errors, like segmentation faults, and, once such an error occurs, prints a debugger backtrace to standard output before exiting the program. It is intended to be used to debug ...

The "Devel::GDB" package provides an interface for communicating with GDB. Internally, it uses the *GDB/MI* interpreter (see <http://sourceware.org/gdb/current/onlinedocs/gdb_25.html>), which accurately informs the caller of the program state and, th...

From one line data dumping sanity checks to debug print statements in a large body of code I often found myself reinventing these basic solutions. Hence this module was born to help give a host of functions/functionality with a minimum of typing/effo...

A "Devel::MAT" instance loads a heapdump file, and provides a container to store analysis tools to work on it. Tools may be provided that conform to the Devel::MAT::Tool API, which can help analyse the data and interact with the explorer user interfa...

"Devel::MRO" provides several mro functions for XS modules. This module provides only a header file, mro_compat.h, so you need not load it in your modules....

PerlDeBugger is a Curses-based Perl debugger with most of the essential functions such as monitoring windows for paddlist, call stack, custom watch expressions, etc. Suitable for debugging or tracing complicated Perl applications on the spot. FUNCTIO...

Devel::Spy is a transparent wrapper over your objects and data. All accesses are logged. This is useful for instrumenting "black box" code. You can just look at see what the code used and how it used it. I used it to find out what attributes and valu...

This module sets signal handlers for "SIGSEGV", "SIGBUS", "SIGILL", "SIGFPE", "SIGTRAP", "SIGABRT" and "SIGQUIT" that prints a stacktrace and some more information about the fault to stderr before dying. This enables debugging even without gdb being ...

The Carp routines are useful in your own modules because they act like die() or warn(), but report where the error was in the code they were called from. Thus if you have a routine Foo() that has a carp() in it, then the carp() will report the error ...

In the Perl debugger, code created via a string eval is effectively invisible. You can run it, but the debugger will not be able to display the code as it runs. For modules that make heavy use of code generation, this can make debugging almost imposs...

Given a list of Perl modules/filenames, this module makes "require" and "use" statements fail (no matter the specified files/modules are installed or not). They *die* with a message like: Can't locate Module/ToHide.pm (hidden) The original intent of ...

Perl keeps arrays of subroutines that are executed at the beginning and at the end of a running Perl program and its program units. These subroutines correspond to the special code blocks: "BEGIN", "UNITCHECK", "CHECK", "INIT" and "END". (See details...

If you use this module from the command-line, the last value of your one-liner ("-e") code will be serialized as JSON data. The expression is evaluated in scalar context. The output will be either UTF-x (UTF-8, UTF-16...) or just ASCII, depending on ...

Devel::Leak has two functions "NoteSV" and "CheckSV". "NoteSV" walks the perl internal table of allocated SVs (scalar values) - (which actually contains arrays and hashes too), and records their addresses in a table. It returns a count of these "thin...

This module provides a clean way of specifying your script's main routine....

A Devel::Memo object is defined as a subroutine reference to do some sort of calculation, together with a simple sort of prototype. The elements of the prototype may be: -eq, indicating a simple scalar argument (number or string); -equal, indicating ...

This is an interactive shell for Perl, commonly known as a REPL - Read, Evaluate, Print, Loop. The shell provides for rapid development or testing of code without the need to create a temporary source code file. Through a plugin system, many features...
