why I see ^G in the NERDTree explorer

[reubinoff]

when I enable this plugin, I see the ^G in the NerdTree explorer

[reubinoff]

workaround is to put:
let g:NERDTreeNodeDelimiter = "\u00a0"
in vimrc

[PhilRunninger]

@reubinoff , that is the correct workaround, but I'm curious to know why you are seeing the ^G. It should be concealed. What version of vim are you using? Are there other plugins that could be interfering with NERDTree? What other settings do you have in your vimrc?

Thanks!

Thank you very much. It works for me.

[PhilRunninger]

@reubinoff I see from the output of your :version command that the conceal feature was not included in your build of vim. @keonjeo, I'm just guessing, but it's probably the case for you too. If you can compile your own vim from source, you could turn that on with the right switches, and then you wouldn't need the workaround.

Because you don't have the conceal feature, the syntax file instead links the NERDTreeNodeDelimiter highlight group to the Ignore highlight group, which unfortunately doesn't do well with the ^G character.

[cozzbie]

Funny thing is I have the same issue and my conceal flag is intact and only this offered answer cleared things up for me.

Edit

For some weird reason the ^G only shows on some directories and not in others and the solution here causes <a0> to appear in front of file and folder names, where when removing this same line, everything is fine and normal. Wow!!!

[npupko]

Same problem when I set syntax off

[msimkins]

Workaround works for me, Standard vim on MAC does not have conceal either

The workaround works only it adds some extra whitespace between the arrow and folder, if I make it empty I cannot open the folder.

[IAXES]

Best to just re-compile with --with-features=huge (--enable-conceal does not appear to be a valid compile time flag). This resolved the issue easily enough.

Cheers!

[mtilson115]

'brew install vim' could also be a viable solution.

[CharlesB2]

Can it be detected that vim doesn't have the conceal feature, and use appropriate NERDTreeNodeDelimiter?
