[feature request] Find file based on the current buffer

The nixprime/cpsm CtrlP matcher has tihs awesome feature:

cpsm will still attempt to perform matching on an empty query based on the open file in the current buffer.

When the query is empty the match is done based on the current buffer name.

I like this feature a lot because it allows me to quickly switch between the implementation file and his test file. eg: Having the file foo.go open, press <C-p>, select the foo_test.go file…

The current buffer have to be ignore from the search result… (another feature by itself??)

I know such feature can be found in vim-projectionist, but I tend to prefer selecting file though the fuzzyfinder for other reason.

Also, Could it be possible to have another VIM option to always ignore the current buffer name from the search result?

Since we have the feature “Find file based on the current buffer”, I don’t think it is necessary to support it. Because if the file name you intend to find is much similar with current buffer name, it will be placed at the top when no input, meanwhile the current buffer name is at the bottom(we can think it is ignored). If not similar, the current buffer name won’t bother you at the top.

Maybe I will add this feature in the future, currently, you can achieve similar effect through this: If you opened foo.go using LeaderF by typing foo, then launch LeaderF, press <up>, you will see the last search result.
