Open source project developed by a team at Google and many contributors from the open source community.

Go version 1.9 moves confidently to final release. Second release candidate is now available.

Let's figure out, what main features Go 1.9 has.

There are two changes to the language.

  1. Go now supports type aliases to support gradual code repair while moving a type between packages. The type alias design document and an article on refactoring cover the problem in detail. In short, a type alias declaration has the form:
    type T1 = T2
    This declaration introduces an alias name T1—an alternate spelling—for the type denoted by T2; that is, both T1and T2 denote the same type.
     
  2. A smaller language change is that the language specification now states when implementations are allowed to fuse floating point operations together, such as by using an architecture's "fused multiply and add" (FMA) instruction to compute x*y + z without rounding the intermediate result x*y. To force the intermediate rounding, write float64(x*y) + z.

Use issue tracker to report any found bug.

If you have Go installed already, the easiest way to try go1.9rc2 is by using this tool.

You can download binary and source distributions from the usual place.

Documentation for Go 1.9 available here.

 

GoLand 2018.3 to be Released by JetBrains

New version of IDE for Go programming language has a lot of new features
22 November 2018   370

Team JetBrains introduced a new version of IDE GoLand 2018.3. In this update, users will see:

  • refactoring by changing the signature;
  • memory dump;
  • Testify support;
  • new debugger tools;
  • Improved verification, prediction and code completion;
  • chart support;
  • updates for VCS, Docker, Kubernetes.

The new method of processing the code Change Signature will allow a single action to change the signature of functions and methods throughout the workspace. The function will show what will change in the code after application. The Inline tool will highlight the embedded code, and Rename will notify you of possible conflicts when renaming.

Added the ability to run and debug Google App Engine applications locally.

Go memory dumps are now available via Run / Open Core Dump directly in the IDE. To automatically create memory dumps, you need to enter GOTRACEBACK = crash in the Environment field.

Also, GoLand 2018.3 supports the Mozilla debugger rr, which allows you to search for a crash in the program by playing back its execution.

The previous version of GoLand 2018.2 was released in July 2018.
