When the current dir is no .git or other project...

[stevedsun]

I have set this:
let g:ctrlsf_default_root = 'project'

But when the current dir is not project, ctrlsf.vim will throw an error.
I think it could be switched default root more automaticly :)

Could you post the error message about what happened when the project root was not found? Turn on the debug mode by let g:ctrlsf_debug_mode = 1 to get more information.

CtrlSF should search current file if no project root is found, if that is not the case, maybe it's a bug.

When search "sudo" at the home dir in vimrc file.

Well, it's a problem about output from Ack if only a file is specified, I need some time to fix it.

Before that, you can switch to Ag by let g:ctrlsf_ack = 'ag', to work around it.

Fixed in V1.4 and merged, thank you for your bug report!
