zchee / nvim-go

Go development plugin for Neovim written in pure Go

nvim-go

nvim-go is a Go development plugin for Neovim written in pure Go.

Requirements

Neovim

Installing Neovim - Neovim wiki

Go

Getting Started - The Go Programming Language

Requires Go 1.11.x or higter. or, use devel.

Install

nvim-go uses Go 1.11 Modules.

We can build nvim-go outside $GOPATH. It's still early development feature. For use it, needs to:

export GO111MODULE='on'

After that, Just add following line to your init.vim:

" dein.vim
call dein#add('zchee/nvim-go', {'build': 'make'})

" NeoBundle
NeoBundle 'zchee/nvim-go', {'build': {'unix': 'make'}}

" vim-plug
Plug 'zchee/nvim-go', { 'do': 'make'}

Features

• First goal is fully compatible vim-go.
  • See TODO.md.
• Delve debugger GUI interface.

nvim-go's Issues

imported and not used

Hello,

I'm getting an error when I'm running make on the plugin.

lint.go:19:2: imported and not used: "nvim-go/log"
nvim-go/command/delve
FATAL: command "build" failed: exit status 2

Do nvim-go will add syntax hightlight?

Do nvim-go will add syntax hightlight?

Exit status: 2 when installing

When doing PlugInstall after following instructions, I was given the following error:

  1 x Post-update hook for nvim-go ... Exit status: 2                                                │~

How do I find out what went wrong?

Run goimports on save

Since one of nvim-go stated goals is to be fully compatible with vim-go, I noticed that one of the config options missing at the moment is what command to run for auto formatting when saving.

Basically, we should have a way of specifying a similar flag/variable as done in vim-go with:

let g:go_fmt_command = "goimports"

This runs goimports on save and adds/removes the required/unused imports respectively.

See the mirror issue in vim-go.

Error occurs when I excute :w two or many times in neovim.

When I excute :w many times in neovim, error occur like:
Error detected while processing BufWritePre Auto Command for ".go"
Error detected while processing BufWritePost Auto Command for ".go"
E475:invalid argument: Channel does't exsit.

Install via Plug fails

I'm switching to neovim and try to get nvim-go running. My Plug section in my init.vim looks like this:

call plug#begin('~/.vim/plugged')

Plug 'zchee/nvim-go', { 'do': 'make'}
Plug 'sebdah/vim-delve'

call plug#end()

If I open nvim and run PlugInstall, I get the following errors:

Error detected while processing
/home/domma/.vim/plugged/nvim-go/plugin/nvim-go. vim: line 20:
E121: Undefined variable: g:go#debug

I checked the file and the error makes sense. But I have no idea where this variable comes from, how it should be set. How can I fix this?

Gobuild does nothing

running :Gobuild shows or does nothing. Then, after running it once, running it again shows E475: Invalid argument: Channel doesn't exist

snippets directory

Should we support ultisnips as well, or only neosnippets?

Use GOPATH to determine the GB_CMD in Makefile

Can we change from:
GB_CMD := gb
to
GB_CMD := $(GOPATH)/bin/gb
?

I think this way will make it easier for everyone.

is it fully vim-go compatible?

the TODO.md in the readme is a deadlink, so what is the progress?
