Editor configuration

To get your editor to behave properly with code that uses cff, you need to add -tags cff to your build tags.

The instructions for this vary on which editor you're using.

• gopls
  • VSCode
  • vim-go
  • nvim-lspconfig

gopls

Most editor integrations with vim, emacs, neovim, and VSCode use gopls (opens new window).

With gopls, you have to set the buildFlags setting (opens new window) to ["-tags", "cff"].

Editor-specific instructions for gopls follow.

VSCode

If you're using VSCode:

1. Locate the gopls configuration section in your settings.json. It might look like this:

   "gopls": {
     ...
   }
   

2. Configure build.buildFlags to set the cff tag.

   "gopls": {
     ...
     "build.buildFlags": ["-tags", "cff"]
   }
   

vim-go

If you're using vim-go, add the following to your .vimrc.

let g:go_build_tags = 'cff'

nvim-lspconfig

If you're using Neovim's built-in LSP client with nvim-lspconfig (opens new window):

1. Locate the gopls.setup call in your init.vim or .vimrc. It should look similar to one of the following:

   require('lspconfig')['gopls'].setup {
     -- ...
   }
   

2. Add a settings.gopls section to it if it doesn't already exist, and configure buildFlags to set the cff tag.

   require('lspconfig')['gopls'].setup {
     -- ...
     settings = {
       gopls = {
         buildFlags = {'-tags', 'cff'},
       },
     },
   }
