Debugger Selector (DbgSel) is a program that allows developers to easily switch from one debugger to another. debugger Selector will also allows users to restore the default debugger settings in case they were lost.

ScriptDebugger is a small debugger application that can help you when debugging VB script.

Zeta debugger is a stand-alone source level debugger and code profiler for applications written for Windows 98/2000/XP. Debugging could be done either at the level of machine instructions, or at the source level, when the source code is in C/C++ and debugging format emitted by your compiler is one of those supported by our debugger or external plug-in modules, which can be easily written by most users.

Zeta debugger supports several debugging formats used by compilers of two most known companies - Borland (BC5, BC4) and Microsoft (VC6, VC5). Other versions will be added later.
Here are some key features of "Zeta Debugger":

· Built-in support of Borland C++ and Visual C++ compilers
· Plug-in API, from which you can load any other debugging formats
· Plug-in API to execute user written commands
· The single navigator window with multiple functions
· Graphical representation of jumps between instructions
· Animation of process execution
· Syntax hiliting for C/Asm panels
· Back Step command, undoing changes made by last instruction
· Full and convenient keyboard control
· Popup help window for keyboard commands
· Inspector of programs structure
· Data guards on memory read/write operations
· Cover panel with the list of recent files
· Graphical representation of current modules sections
· Automatic symbol hyperlinks in C/Asm panels
· Automatic / manual insertion of comments
· Automatic address correction after program recompilation
· List view of call frames
· Log file navigator
· MMX registers
· Support for 64 integer expressions
· jit (Just In Time) debugging support


Limitations:

· 30 days trial

DBG description
DBG is a a full-featured php debugger, an interactive tool that helps you debugging php scripts DBG works on a production and/or development WEB server and allows you debug your scripts locally or remotely, from an IDE or console.

Here are some key features of "DBG":

· Native debugger. Works transparently, neither script nor PHP engine modifications required.
· Server part (dbg module) runs on all platforms where PHP itself runs.
· Works transparently across the global network as well as locally.
· JIT. When enabled it can start debugging Just In Time when an error happens.
· Supports back-trace, e.g. displays a list of all procedures with their local variables, the current execution position reached from. In other words you can watch local variables or function parameters in all active and nested scopes.
· Certainly, you can execute script in the debugger step by step (step-in, step-out, step-over, run to cursor, change execution point withing current scope...), evaluate any valid php expression(s) or inspect arrays, classes and simple variables, modify their values on the fly and even create any new variables. Dbg supports conditional breakpoints and even global ones (commercial version only). Breakpoints can be skipped specified number of times.
· Allows to change execution point (commercial version only).
· Has embedded profiler, so now its easy to find out a bottleneck in the scripts.
· Allows multiple debugger processes running simultaneously.
· Compatible with php-4.0.6 and higher.
· Has open COM interfaces for integration with win32-based 3rd party IDEs.
· Commercial version of DBG (3.x) is available with commercial version of PhpED PHP IDE only, see review for details.
· Win32, Linux, SunOs, MacOs, and BSD platforms are supported.
· DBG works with PHP Coder, PHP Edit, and some other IDEs.

CrashDoctor description
CrashDoctor protects your programs from crashing due to invalid memory access and other errors CrashDoctor is a program developed to recover crashing programs. It works as a jit windows debugger and activates when a windows program crashes. It then attaches to the program and tries to recover the program from crashing state by careful analysis of the program.

CrashDoctor has another useful feature, once a program crashes, CrashDoctor monitors the execution of the program. If the program tries to open an existing file for writing CrashDoctor intercepts this and copies the original file to a backup location.

This prevents any further damage done by the misbehaving program. The current version of CrashDoctor however doesnt prevent this if program already has these files open.

CrashDoctor also works like a debugger chooser. After installing CrashDoctor if a program crashes, the CrashDoctor recovery screen shows up. This screen lists debuggers available on the system and you can select a debugger to debug the crashing program instead of recovering its crash. Note here that once you start debugging the program, you wont be able to recover it.

Few words about Crash
A crash can happen in a process due to various reasons like accessing invalid memory locations, resource constraints, resource unavailability etc. One thing to note here is that a crash almost always occur due to bad programming such as not handling error conditions properly.

CrashDoctor tries to recover all the crashes, sometime the crash is so fatal that repeated attempts to recover it fails and in such case, CrashDoctor terminates the process and displays the exit code of the process.

Here are some key features of "CrashDoctor":

· Runs as jit debugger so no overhead when no program is crashing
· Extremely light-weight and doesnt slow down the process even when recovering it from the crash
· Once a process crashes, CrashDoctor intercepts if the process tries to open a file for write and makes a backup copy of the file to prevent data loss
· Works as a debugger chooser also if you have multiple debuggers in your system. Upon a program crash, you can chose which debugger to use to debug the program (in case you dont want to recover the process from crashing).
· Comes with an easy to use graphical user interface


· Whats New in This Release:

· Created a version for AMD64
· Improved crash recovery for x86 as well as added enhanced crash recovery for AMD64
· Improved the color-scheme for better readability

A lightweight yet powerful GUI debugger for your perl scripts that lets you focus on the code.

A debugging took kit for Delphi 3.0 that includes: Hawk Eye-The Component debugger and Eye Spy-The Application Spy. Hawk Eye is the only complete component debugger for Delphi components. Use Eye Spy to spy on Delphi applications.

Script debugger IDE is a development platform for building custom business solutions. It includes a powerful script and form editors and debugging tools. Script debugger IDE can be integrated in any application. This inclusion makes it much easier for developers to create custom solutions using Script debugger IDE and to reuse code across the applications. Script debugger IDE supports full client and server script debugging using everything you expect from a full-featured debugger. You can use the Script debugger IDE to test scripts written in Microsoft Visual Basic Scripting Edition (VBScript) and Microsoft JScript. Powerful, cross-process debugging is one of the most compelling features of Script debugger IDE.

Expert debugger is a free easy-to-use tool for debugging PHP scripts. Expert debugger uses the DBG PHP debugger and allow to debug scripts via network or on local computer. You can run scripts in step-by-step mode and to trace values of any variables and script output. The debugger has a comfortable interface and can be integrated with IDE or editors.
