What's New in GoLand

Starting with Go 1.16, you’ll be able to embed files and directories into a Go binary at build time.

Embedding works on a few types of variables: string, []byte, and embed.FS. You need to declare these variables at the top level of your package. Finally, you need to add the //go:embed directive for embedding to work.

GoLand provides code highlighting, navigation from references inside the embed directive to files and folders in your project, Rename refactoring, Find Usages, code completion, and a few code inspections. For example, GoLand will notify you if you try to embed files into a variable of the wrong type.

In Go 1.16, go vet detects incorrect usages of asn1.Unmarshal, making sure that the value in which a slice of bytes is unmarshaled is not nil.

GoLand 2021.1 provides a similar check with a quick-fix to resolve this problem.

Generate a struct with fields and tags from JSON in no time by simply copy-pasting JSON data into the editor.

If you want to adjust the JSON before generating a struct, press Alt+Enter to invoke the Generate type from JSON intention. GoLand will open the Generate Go type from JSON window with the copied JSON. You can tune it as you wish in the window, then press the Generate button and your struct will be ready to go. Of course, it’s also possible to paste JSON into the window manually.

Additionally, it’s possible to convert JSON inside an already existing empty struct. To do so, just click this empty struct and call the Generate struct fields from JSON intention action by pressing Alt+Enter or by using the Generate menu.

Besides that, GoLand will notify you if you use invalid JSON code in the Generate Go type from JSON window.

Last but not least, GoLand 2021.1 supports the newline-delimited JSON Lines at used for working with structured data and logs. The IDE will recognize .jsonl, .jslines, .ldjson, and .ndjson file types.

In this format, files contain several lines, and each new line is a JSON object separated by a newline character. Commas are required at neither the beginning nor end of lines, and there is no need to enclose the entirety of the file contents in square or curly braces.

We’ve expanded the application area of the quick-fix that addresses type incompatibility. It now also suggests implementing an interface and converting to the expected type inside composite literals.

The Create Type quick-fix offers not only to create a type when GoLand notices you are using one that has not yet been defined, but also it will create fields for you as well.

Generating get and set methods for each field in huge structs can be rather tedious. You can now generate getters and setters for the whole struct all at once.

Press Alt+Enter on any field name in the struct, then choose Generate getter and setters from the drop-down menu. GoLand will open the Select Fields window, where you can generate get and set methods for all the fields or just for the fields you need.

The Configuration widget, which was previously available in the bottom left-hand corner of the IDE, has been replaced with a quick access menu. This new menu appears in the top right-hand corner. Press the gear icon to switch themes or keymaps, navigate to plugins, or go to the settings.

You can now access your recent projects by right-clicking on the GoLand icon on the taskbar or on the Start menu in Windows.

Tooltips are now shown one after another to prevent them from overlapping.

You can now select the font variations from the Settings | Editor | Font settings panel.

We’ve added a new built-in browser preview that helps you quickly preview HTML files. Any changes you make to HTML files in the IDE, as well as in the linked CSS and JavaScript files, will be immediately saved, and the preview will update on the fly.

To open the preview, click on the GoLand logo in the widget located in the top right-hand corner of the editor.

Need more space when working on multiple files simultaneously in a split editor? Double-click the tab you’re working with to maximize the editor window for it. To bring that tab back to its original size, simply double-click it again.

The Makefile Language plugin (previously 3rd-party), which provides GNU Make language support, is now bundled by default. Starting with GoLand 2021.1, you will get syntax highlighting, quick documentation, Find Usages for targets, and some navigation and code completion actions for Makefile right out of the box!

We've improved the Run/Debug Configuration dialog in several ways:

• To add all the necessary build options, click Modify options; to add run options, click Modify. The IDE now validates each option to make sure it is compatible.
• For Docker-compose, we support all the existing options, including the one for declaring Environmental variables files (.env).
• For Dockerfile, you don’t have to remember all the run commands because code completion works in the Run Options field.
• For Docker Image, you can use code completion to enter the name of the image in the Image ID or name field.

We’ve added experimental support for BuildKit, which makes building projects much faster. You can activate this option in Run/Debug Configurations by clicking Modify options and selecting Enable BuildKit (experimental).

Simply click the hammer icon next to the stage name, and the IDE will build the image using BuildKit. If you add the Run section in Run/Debug Configurations, the icon will change. When you click it, you will not only build an image but also run a container.

If you use multiple FROM statements in your Dockerfile, each FROM instruction starts a new stage. In GoLand 2021.1, you can now fold stages and see a distinct separator line between them.

If you decide to stop a running Dockerfile, you can easily do so in the Services tool window. Select the running item, call up the context menu, and click Stop Deploy.

When using bind mounts, you can now enter a path to a directory on the host machine faster. The completion mechanism allows you to select macros and environmental variables in the Bind mount option in Run/Debug Configurations.

Last but not least, we've added completion for image names.

Inspecting your CSS code with Stylelint is now easier. You can now fix problems with this popular linter in just a few clicks. Hover over a problem in your file or place the caret on it and press Alt+Enter, then select Stylelint: Fix current file.

Additionally, you can now specify a path to the configuration file under the corresponding field in Settings | Languages & Frameworks | Style Sheets | Stylelint.

When working with style sheets, you can now check the specificity of your selectors – just hover over a selector that you want to check. Alternatively, focus on a selector and press Ctrl+Q to see this information in the Documentation popup.

We’ve improved the sorting of data:

• A new ORDER BY field works similar to the WHERE field (which was called Filter before): enter a working clause to have it applied to the query of the grid.
• The sorting is not ‘stacked’ by default. This means that if you click on a column name to sort data by, the sorting based on other columns will be cleared. If you would prefer to use stacked sorting, click a column name while holding the Alt key.
• If you want to use sorting on the client side (GoLand will not rerun the query nor sort the data within the current page), uncheck Sort via ORDER BY.
• It’s also possible to open tables with predefined sorting based on the numeric primary key.

This is our solution for anyone wanting to generate simple statements straight from the database explorer. General live templates cover many cases where you need to write a simple query quickly. But we also understand that sometimes, when you are in the context of the database explorer and you are already focusing on the object you need, there is a better way to get a simple query using that object.

Select first N rows from a table looks like a general template (and can be used as such). Since this particular syntax cannot be used in all databases, the corresponding dialects are set for the template. The major difference that makes this template applicable in the database explorer is the special expression dbObjectName, which is used for the $table$ variable.

We’ve added a UI for editing grants when modifying objects.

The Modify user window, which you can invoke on a user in the database explorer with Ctrl+F6, now has a UI for adding grants to objects.

This is available for PostgreSQL, Redshift, Greenplum, MySQL, MariaDB, DB2, SQL Server, and Sybase.
