Vim-go: I have some issues when I save go file.

[stdhi]

What did you do? (required. The issue will be closed when not provided.)

maybe a bug report.

What did you expect to happen?

fix the error alert.

What happened instead?

when I try to save go file, there is a error message alert:

Error detected while processing function <SNR>73_fmt_autosave..go#fmt#Format..go#fmt#run..<SNR>115_fmt_cmd:
line    8:
E706: Variable type mismatch for: opts
line   10:

Configuration (MUST fill this out):

• vim-go version: commit afbfc3765335626b21be2d656f22aecfcb125781

• vimrc you used to reproduce (use a minimal vimrc with other plugins disabled; do not link to a 2,000 line vimrc):
  I don't know how to cut the vimrc for short. full link: vimrc

• Vim version (first three lines from :version):
  VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Aug 2 2017 00:45:39)

• Go version (go version):
  go version go1.10.1 linux/amd64

I fix it. I checkout to the v1.17 release version.

[bhcleek]

What is the value of your g:go_fmt_options?

[stdhi]

@bhcleek nothing, I didn't set the g:go_fmt_options.
this is the output:

:let g:go_fmt_options
g:go_fmt_options

[nkane]

setting let g:go_fmt_options = 0 in my .vimrc stopped this from occuring. I switch to the tag v1.17 prior to setting that in my .vimrc, but that didn't help 🙁

• Update, switching to let g:go_fmt_options = 0 disabled the go fmt that was happening on save, so I switch it to let g:go_fmt_options = '', and it appears to be formatting properly now.

I have the same issue to save go file on master. Checkout to v1.7, v1.8 or v1.9 can fix the problem.

[pavel-odintsov]

Any ideas how I can fix it?

@stduolc it appears that you're using an old version of Vim that vim-go does not support. vim-go currently requires _at least_ Vim 7.4.2009
