Time travel debugging or time traveling debugging is the process of stepping back in time through source code to understand what is happening during execution of a computer program. [1] Typically, debugging and debuggers , tools that assist a user with the process of debugging, allow users to pause the execution of running software and inspect ...
It can be used to track the flow of data values of a piece of code. This type of debug code has some distinct disadvantages. It is temporary and usually removed when the bug is solved. The use of many print statements can affect the actual output of a program and slow down the run-time, depending on how often print statements are called.
Time travel debugging is the process of stepping back in time through source code (e.g. using Undo LiveRecorder) to understand what is happening during execution of a computer program; to allow users to interact with the program; to change the history if desired and to watch how the program responds.
Program animation or stepping refers to the debugging method of executing code one instruction or line at a time. The programmer may examine the state of the program, machine, and related data before and after execution of a particular line of code.
Code::Blocks — A free cross-platform C, C++ and Fortran IDE with a front end for gdb. CodeLite — An open source, cross platform C/C++ IDE which have front end for gdb, the next version of CodeLite (v6.0) will also include a front end to the LLDB (debugger) Eclipse C/C++ Development Tools (CDT) [2] — includes visual debugging tools based ...
time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
Step debugging is a powerful tool that allows you to step through code one line at a time, and hover over variables to see their contents at the time of execution. IDEs that easily support Lua step debugging include ZeroBrane Studio, and IntelliJ IDEA with various debugger plugins (Emmy Lua or Lunalysis).
A program known as a debugger can help a programmer find faulty code by examining the inner workings of a program such as executing code line-by-line and viewing variable values. As an alternative to using a debugger, code may be instrumented with logic to output debug information to trace program execution and view values.
