Ctrlp not working with paths with hash marks

[j5shi]

• Found Ctrlp doesn't work with paths with hash marks (#).
• Tested on CentOS 7.

[mattn]

Could you please show me your configuration for ctrlp.vim? I can't reproduce this.

Hi, I found the root cause of this issue was that the escaped path broke some vim builtin functions, like readdir() here, and as far as I know there are some other builtin functions having the same issue. These functions does not recognize escaped paths, e.g. /this/is/escaped\#/path where # was escaped. So I tried to de-escape the path (e in the image) before passing it to these functions and then it worked. I used substitute() as I could not find a better way to restore the escaped path to it's original state.

Hi mattn, any plan to fix this? Shall I make a pull request for it?

[mattn]

I wonder where the escaped # comes from.

[j5shi]

It was generated by ctrlp itself.

[mattn]

I guess it is utils.vim:82. But it is not called with a:type=c

[mattn]

Could you please try this patch?
