vim-go/synstastic Errors not automatically displaying on save

Question

I noticed that when I save a file and I have a syntax error in my code, the error quickfix window does not automatically appear. I recently rebuilt my system and simply copied over my .vim/ directory along with the same .vimrcfile. I've done this before and have never had any issues. However, if I manually enter :GoErrCheck or GoBuild, the window shows up. What gives?

Here is my .vimrc

Answer 1

Readme file in vim-go explains its usage with syantastic

Sometimes when using both vim-go and syntastic Vim will start lagging while saving and opening files. The following fixes this:

let g:syntastic_go_checkers = ['golint', 'govet', 'errcheck']
let g:syntastic_mode_map = { 'mode': 'active', 'passive_filetypes': ['go'] }

Another issue with vim-go and syntastic is that the location list window that contains the output of commands such as :GoBuild and :GoTest might not appear. To resolve this:

let g:go_list_type = "quickfix"

In this issue

One recommendation is to remove the lines

let g:syntastic_go_checkers = ['golint', 'govet', 'errcheck']
let g:syntastic_mode_map = { 'mode': 'active', 'passive_filetypes': 

and use

let g:syntastic_go_checkers = ['govet', 'errcheck', 'go']

instead

Answer 2

Assuming you are talking about errors shown by syntastic, this issue is probably similar to the one discussed here : vim-go with syntastic

Synastic doesn't check Go files on save by default (anymore). Add this to your .vimrc to make that happen:

let g:syntastic_go_checkers = ['go']
