Missing argument `ctermbg` error

[fortes]

Hi there, I get the following error when using a minimal setup:

Error detected while processing function search_pulse#Pulse[13]..search_pulse#P
ulseCursorLine[44]..<SNR>71_SetCursorLineColor:                                
line    1:                                                                     
E417: missing argument: ctermbg=  

I can reproduce this with the following .vimrc (uses vim-plug, but that should not matter):

call plug#begin()
Plug 'inside/vim-search-pulse'
call plug#end()

Here is my system info (I run vim in the terminal):

The plugin works fine in my normal setup, but breaks once I tried to move to a different colorscheme (I use hybrid normally)

Thanks for the great plugin!

(Originally I thought this was due to base16, but I removed that colorscheme and still get this error)

Hi fortes,

I can't reproduce but can you try it again with this patch applied where the bundle is installed?

Thanks!

Just tested and that works! Thanks for fixing!

You're welcome! I just pushed this fix on the master branch. You can remove your local change and update the plugin with :PlugUpdate vim-search-pulse.
