Let's look at the workflow of incrementing the major version of a module using the module definition taken from our What's New in GoLand repository: module renameab.le/module go 1.11 Upgrading a module means bumping the version tag in version control. We also need to change our import paths. For example, if to bump the module version from `v1` to `v2`, we need our imports changed from: "renameab.le/module/pkg/log" to "renameab.le/module/v2/pkg/log" Obviously, this can appear in lots of places in the code. Good news: the IDE can do this for you. With the 2021.1 version of

One of the most anticipated features of Go 1.16 is the support for embedding files and folders into the application binary at compile-time without using an external tool. This feature is also known as go:embed, and it gets its name from the compiler directive that makes this functionality possible: //go:embed. With it, you can embed all web assets required to make a frontend application work. The build pipeline will simplify since the embedding step does not require any additional tooling to get all static files needed in the binary. At the same time, the deployment pipeline is predictable

Today, I'm happy to introduce our latest feature to you to use Windows Subsystem for Linux version 2 (WSL 2, or simply WSL) to run or test Go applications seamlessly. This feature is called Run Targets and supports WSL 2, Docker, and SSH remotes. If you'd like to learn more about these, the overview article of this feature, explaining it in more detail, should come in handy. In this article, I'll focus on the WSL 2 side of this feature. If you wish to use other targets, you can check the article covering the Docker target. If you'd prefer a video version of this article, then please head t

Up until now, when you wanted to test or run your shiny new code, you had only the local machine to do so. Many of our users have told us that they'd prefer to use Docker to run their code since that's where they will ultimately test, build, and deploy the code with their CI/CD pipeline. Today I'm happy to introduce to you our latest feature that allows you to seamlessly use Docker containers for your workflows from the comfort of your IDE. We call this feature "Run targets", and it doesn't extend to Docker support only. We currently support Docker, WSL 2, and SSH remotes. You may

Previously, when you were using GoLand, you could test and run your code only on the same machine you had the IDE installed on. You could use the FTP/SFTP Connectivity (ex. Remote Hosts Access) plugin and the Settings/Preferences | Tools | External Tools feature or the built-in Docker plugin to achieve some sort of workflow. However, this was not convenient to use and did not have the integration level that our users expect when using our tools. That is why our team embarked on a journey to provide a better experience for these kinds of workflows. And that's how the Run targets feature came

In today's article, we will experiment with generics in Go, and their latest form, Type Parameters. Before we start, let's take a quick look at the proposal's history. History of generics in Go Generics have been some of the most desired language features since Go's inception. While the Go team never explicitly rejected them, they also did not have a good way to solve the problem of introducing generics to the language without making Go look and feel less Go-like. That was until August 2018, when the Go team introduced the notion of Contracts and started a big discussion with the community a

During our recent webinar, we shared over 40 GoLand tips & tricks that you can use to boost your productivity with the IDE. Here's the summary of the presentation and all the tips shown: 00:00:18 - Organize projects in IDE 00:01:13 - Hide/Show Editor tabs 00:01:44 - Using the Zen Mode 00:02:09 - Show/hide the Project View Tool Window 00:02:24 - Use the Navigation Bar 00:03:04 - Import a package without typing its name 00:03:43 - Smart Type Completion 00:04:34 - Postfix Completion 00:05:43 - Method-like Completion (more…)

We released an EAP version for a seamless integration of this feature, see https://blog.jetbrains.com/go/2021/02/12/goland-2021-1-eap-3/#run_target_for_wsl Please provide feedback for it. Thank you! Windows Subsystem for Linux, or WSL as it's commonly known, allows Windows 10 to run Linux inside Windows. We are going to have a look at WSL 1 since, as of the publishing of this article, WSL 2 is not officially released yet. After installing WSL 1, and enabling your preferred Linux distribution on it, you can set up Go as you would on a normal Linux installation. You should also install Go for W

Last week we hosted our first webinar, with the theme of Go Microservices development in GoLand. It was great to see so many people attending, asking questions, and giving us their feedback. To that end, I'd like to say a big thank you to everyone who participated, as well as to our JetBrains team that made this all possible. During the webinar, we promised to reply to as many questions as we can, and that's what we're doing in today's blog post. Here's a quick recap of the presentation: We used a basic "Hello World" application using net/http as a base project. We then deployed a datab
