The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.
The .debug_info section of an ELF contains information generated by compilers to describe the source code while debugging by keeping symbols and its type, scope, file, line number, etc. The .debug_info [1] section is one of the main components of DWARF [2] [3] debug info files. [4] This is generated by a compiler when -g switch or its variants ...
Several open-source scripts have been developed to facilitate the construction of Python one-liners. Scripts such as pyp or Pyline import commonly used modules and provide more human-readable variables in an attempt to make Python functionality more accessible on the command line. Here is a redo of the above example (printing the last field of ...
A debug menu or debug mode is a user interface implemented in a computer program that allows the user to view and/or manipulate the program's internal state for the purpose of debugging. Some games format their debug menu as an in-game location, referred to as a debug room (distinct from the developer's room type of Easter egg).
After the bug is reproduced, the input of the program may need to be simplified to make it easier to debug. For example, a bug in a compiler can make it crash when parsing a large source file. However, after simplification of the test case, only few lines from the original source file can be sufficient to reproduce the same crash.
Memory debuggers work by monitoring memory access, allocations, and deallocation of memory. Many memory debuggers require applications to be recompiled with special dynamic memory allocation libraries, whose APIs are mostly compatible with conventional dynamic memory allocation libraries, or else use dynamic linking.
To avoid facing too many errors at once, the general strategy is to make "one small change" at a time, do a run show-preview, and then save that tested version after a few good changes to have a stable version to restore, in case terrible errors occur after numerous later changes.
Command-line completion generally only works in interactive mode. That is, it cannot be invoked to complete partially typed commands in scripts or batch files, even if the completion is unambiguous. The name tab completion comes from the fact that command-line completion is often invoked by pressing the tab key.
