[WIP] go.nvim

A modern golang neovim plugin based on treesitter and nvim-lsp. Written in Lua. Async as much as possible. PR & Suggestions welcome

install

add 'ray-x/go.nvim' to your package manager related binaries will be installed the first time you using it Add lsp format in your vimrc. You can check my dotfiles for details

require('go').setup()

code format

nvim-lsp support goimport by default.

autocmd BufWritePre (InsertLeave?) <buffer> lua vim.lsp.buf.formatting_sync(nil,500)

The plugin provides code format, by default is goline + gofumports (stricter version of goimport)

The format tool is a asyn format tool in format.lua

require("go.format").gofmt()
require("go.format").goimport()

Textobject

Supported by treesitter. TS provided better parse result compared to regular expression.

Build and test

Provided wrapper for gobulild/test etc

unit test with gotests

Support table based unit test auto generate, parse current function/method name using treesitter

Modifytags

modifytags by modifytags and treesitter

GoFmt

nvim-lsp support goimport by default. The plugin provided a new formatter, goline + gofumports (stricter version of goimport)

Comments and Doc

Auto doc (to suppress golang-lint warning), generate comments by treesitter parsing result

type GoLintComplaining struct{}

 lua.require('go.comment').add_comment() -- or your faviourite key binding and setup placeholder "no more complaint ;P"

The code will be:

// GoLintComplaining struct no more complaint ;P
type GoLintComplaining struct{}

LSP

LSP supported by nvim-lsp is good enough for a gopher. If you looking for a better GUI. lspsaga and lsp-utils are what you are looking for.

Lint

Supported by LSP, if you need golangci-lint better with ALE

configuration

lua suggested:

require('go').setup(cfg = {
  goimport='gofumports', -- g:go_nvim_goimport
  gofmt = 'gofumpt', --g:go_nvim_gofmt,
  max_len = 100, -- g:go_nvim_max_len
  transform = false, -- vim.g.go_nvim_tag_transfer  check gomodifytags for details
  test_template = '', -- default to testify if not set; g:go_nvim_tests_template  check gotests for details
  test_template_dir = '', -- default to nil if not set; g:go_nvim_tests_template_dir  check gotests for details
  comment_placeholder = '' ,  -- vim.g.go_nvim_comment_placeholder your cool placeholder e.g. ﳑ       
  verbose = false,  -- output loginf in messages
})
