To get started with Delve, install it on your machine using the following line: One of the most popular options, Delve offers an easy-to-use, full-featured Go debugging tool. The default log package works well, but third-party logging frameworks are also available. Even if you use a different method to debug your code, it is always a good idea to implement a proper logging system. You can also automate logging notifications so that you’re notified whenever something goes wrong. With a proper logging method and format implemented, you can catch errors more quickly.
This is the standard approach when using logging as a debugging method. You can also take it a step further and integrate with the os package to write the logs into a new file.

Running this code will give you a log and the date and time. But systematic logging can also be done too broadly without considering the use case, leading to spam logs and further problems.įor basic logging, importing the default log package is enough. Logging is another method of debugging code in any programming language. The fmt package in Golang provides three ways to print anything to the console: Printf, which allows you to format the numbers, variables, and strings Print, which only prints the string passed as an argument and Println, which does the same thing as Print, then adds a new line character ( \n ) at the end of the string passed to it. However, this approach is not as comprehensive as others. You don’t need to install a third-party tool. This is the first approach most developers take because it’s easy to get started by importing the fmt package into the code. The most common way of debugging code in any programming language is using print statements. The Delve debugger was designed to address this need.Īnother option is using the Log package to create custom logs for your code.įollowing are details on the various options. But GDB wasn’t explicitly built for many newer features of the language, such as Goroutines. This can lead to problems when writing code.Īs noted, one standard option for debugging is to use the print statement. Golang is still a relatively new language, and some of its nuances aren’t commonly known yet. Check this article to learn more about them. There are other mistakes that developers should be aware of as well. This is because the map must be initialized with the make method. Assigning a value using the below syntax will create a panic error: If you do not add an exit condition inside a recursive function, the function will run until the system runs out of memory.Īnother common mistake by beginners in Go is assigning entry in nil map. One of the common bugs to watch out for is infinite recursive calls. Because of such issues, it is important to know which tool to use when debugging. Some features of Golang can confuse debuggers and cause incorrect outputs. Typical debuggers offer limited features even though they work with Golang. The print statement is often used to debug small programs, but this can complicate the process when working with a large program. Another benefit of goroutines is that they communicate using channels, which prevent race conditions from happening when accessing shared memory.ĭespite its useful features, debugging in Golang can sometimes be frustrating. Goroutines are cheaper than using threads, and the stack size of a goroutine can shrink or grow according to the need of the application. Goroutines: The introduction of goroutines, or activities that execute concurrently, has made Go a great choice for programmers as well as for DevOps engineers. Go also has concurrency, which means it can run multiple tasks simultaneously.
īuild anything: Golang can be used to build anything from standalone desktop apps to cloud apps. Great community: The Golang community is supportive, and you can get help through Slack, Discord, and even Twitter. Learning curve: Golang is one of the simplest programming languages available, so it’s easy to work with.Įxcellent documentation: The documentation is straightforward and informative. You’ll also learn about emerging tools like live debuggers, which are similar to classic debuggers but can help you get instant debug data and troubleshoot easily and quickly without adding new code or waiting for a new deployment. In this article, you will learn about common bugs in Golang programs, as well as some of the traditional approaches used to debug them. Go is the preferred choice among developers, but its simplicity can also leave it vulnerable to bugs and other programming issues. It was first announced to the public in 2009, and it was made open source in 2012. Robert Griesemer, Rob Pike, and Ken Thompson designed the language at Google. Golang or Go is a well-established programming language ground built for speed and efficiency.
