golang delete breakpoint

In the Go language, breakpoints are an important tool for developers when debugging code. It can help us pause program execution, view the values ​​of program variables, stack information, etc., to better understand problems during program execution. However, in some special cases, we need to clear or delete the breakpoints that have been set. So, how to delete breakpoints in Go language? This article will introduce it to you in detail.

1. GDB debugging tool

In the Go language, the GNU debugger (GDB) is a commonly used debugging tool. It can realize real-time debugging of programs, including setting and deleting breakpoints and other functions. . We can use GDB to debug Go programs. The following are some common commands of GDB:

1. Run the program: run or r

2. Set a breakpoint: break or b

3. Clear breakpoints: clear

4. List breakpoints: info breakpoints

The above commands are used in GDB in the same way as debugging C/C programs. There is no difference here. Again.

2. Delve debugger

In addition to GDB, Delve is also a debugging tool developed for Go language. Compared with GDB, Delve is more convenient and friendly to use. When using Delve for debugging, we can also delete breakpoints through similar commands. The following are some common commands of Delve:

1. Run the program: run or r

2. Set a breakpoint: break or b

3. Clear the breakpoint: clear , clearall and delete

4. List breakpoints: breakpoints or bp

It should be noted that some commands of Delve are different from GDB and require some modifications. For example, to delete a breakpoint, we can use the following command:

(dlv) delete [breakpoint number]

where [breakpoint number] is the number of the breakpoint we want to delete . We can view the set breakpoint numbers through the breakpoints command.

3. VS Code debugging tools

In addition to GDB and Delve, VS Code is also a commonly used code editor. It has a set of built-in debugging tools that can help us quickly debug Go programs. In VS Code, we can use the following command to delete the set breakpoint:

1. Enter debugging mode: F5

2. Set breakpoint: Click on the left side of the editor Number of lines

3. Delete breakpoints: Select "Delete all breakpoints" in the debug menu

It should be noted that when deleting all breakpoints in VS Code, the current code will be deleted. All breakpoints that have been set are deleted. If we only need to remove a specific breakpoint, we can use the line number on the left side of the editor to cancel the breakpoint for that line.

4. Summary

In the Go language, when we use GDB, Delve, VS Code and other tools for program debugging, we can use similar commands to delete the set breakpoints. No matter which debugging tool we use, we only need to remember some basic commands to easily delete breakpoints, thereby effectively improving the efficiency of program debugging.
