Ignore all errors in vimrc at vim startup

Question

I am trying to create an Ansible script to set up my mac. One role is to set up vim. A first clone my dot-files into a local folder and symlink them to ~/. In my vimrc I use vundle to install extension. So I try to start vim to install all extensions like this:

- name: vim | Install vundle plugins
  shell: vim  +PluginInstall +qall

But when I start this, I get the error:

E185: Cannot find color scheme 'molokai'

Is it possible to suppress this error messages for the first startup?

You can include things like custom colorschemes inside try/catch blocks and/or if <loaded condition> finish style include guards. I had the same issues and ended up doing this so that everything still works cleanly if certain plugins aren't installed or disabled. – Fantom

@swalladge That also sounds like a good solution, thansk – Crazy

Answer 1

Possibly you could split your vundler config into its own file vundler.vim, and on your first startup/ansible script you instead run vim -u vundler.vim (you can make it run :VundleInstall or whatever else would be required via some commandline flags too, -E?).

Then in your regular vimrc you just source vundler.vim for your regular day to day usage.

If you can't get the extra command line flag to work you can split it on more level, vundler-ansible-shim.vim that just has source vundler.vim<NEWLINE>:PluginInstall in it. – Orin

You can silence the E185: Cannot find color scheme 'molokai' error in your .vimrc by setting silent! colorscheme molokai then install with i.e.: vim -E -s -u ~/.vimrc +PlugInstall +qall.

I had the same issue. The way I solved this, was by using the stdin argument of the shell module. I'm passing a new line at stdin.

My task looks like this

- name: "Install plugins"
  shell: vim +PluginInstall +qall
  args:
      stdin: "\n"

You might be able to use --clean arg to get around those startup warnings/errors. Once you're inside vim, if you send a second command, it will pass over those warnings/errors.

This worked for me: vim --clean '+source ~/.vimrc' +PluginInstall +qall

(I know this thread is a little old but I came across this issue myself just now.)

I solved this issue by changing my vimrc, to ensure Vim would run without issues, even if there are no plugins installed.

First, set a variable if some plugin isn't installed:

let b:vim_plugged_path = '~/.vim/plugged/'
let b:sample_plugin = 'vim-surround/plugin/surround.vim'
if ! filereadable(expand(b:vim_plugged_path .. b:sample_plugin))
  let g:no_vim_plugins_installed = 1
endif

Then, at a place in vimrc before any errors:

if exists('g:no_vim_plugins_installed')
  finish
endif
