Gofmt

Go takes a strong stance on code formatting. The gofmt tool rewrites code into the standard format.

Golint

Linter is a tool that analyzes source code to flag programming errors, bugs, stylistic errors, and suspicious constructs.
Using Linter provides many benefits.

  • Find bugs
  • Speed up code review
  • Manage code quality

VSCode setup

Install the Go extension maintained by Go Team at Google(previously maintained by Microsoft).

You should immediately see a prompt in the bottom-right corner of your screen titled Analysis Tools Missing. This extension relies on a suite of command-line tools, which must be installed separately. Accept the prompt, or use the Go: Install/Update Tools command.

Also, see the tutorial https://code.visualstudio.com/docs/languages/go

vim setup

Install the vim-go plugin
Plug 'fatih/vim-go', { 'do': ':GoUpdateBinaries' }

The official toturial https://github.com/fatih/vim-go/wiki

Here are some settings from my vimrc file
